Appendix:Glossary of contract bridge

The following terms are used in contract bridge, duplicate bridge, and auction bridge. Some of them are also used in Whist, Bid whist, and other trick-taking games.

Note: Except for those indicated in bold, all links in this article are internal, i.e. lead to other list entries rather than external articles

A



 * Above the line : In rubber bridge, points recorded above a horizontal line on the scorepad. These are extra points, beyond those for tricks bid and made, awarded for holding honor cards in trumps, bonuses for scoring game or slam, for winning a rubber, for overtricks on the declaring side and for undertricks on the defending side, and for fulfilling doubled or redoubled contracts. See Below the line.


 * ACBL : American Contract Bridge League


 * Acol: An approach-forcing, natural bidding system popular in the United Kingdom and the Commonwealth.


 * Active : 1) An approach to defending a hand that emphasizes quickly setting up winners and taking tricks. Contrast with Passive.
 * 2) An approach to competitive bidding that emphasizes frequent interference with opponents' bidding sequences.


 * Adjusted score : In duplicate bridge, a score that penalizes a pair or team that has committed an irregularity, or that compensates a pair or team that has been damaged by an irregularity. The penalty and the compensation need not be commensurate.


 * Advance cue bid : The cue bid of a first round control that occurs before a partnership has agreed on a strain.


 * Advance sacrifice: A sacrifice bid made before the opponents have had an opportunity to determine their optimum contract. For example: 1 - (1SS undefined) - Dbl - (5SS undefined).


 * Advancer : Overcaller's partner, especially one who bids following the overcall.


 * Adverse vulnerability : Vulnerable vs. non-vulnerable. Also called "unfavorable vulnerability."


 * Aggregate scoring : Deciding the outcome of a contest by totaling the raw points gained or lost on each deal. Also called "total point scoring."


 * Agree : To decide, explicitly, conventionally or by implication, in which strain to play a hand.


 * Agreement : An understanding between partners as to the meaning of a particular bid or defensive play.


 * Alcatraz coup: Declarer's intentional and unethical attempt to locate a finessable card by revoking. If the play is unintentional, it is nevertheless subject to score adjustment.


 * Alert : A method of informing the opponents that partner's bid carries a meaning that they might not expect; alerts are regulated by sponsoring organizations such as the ACBL and the EBU, and by individual clubs or organisers of events. Any method of alerting may be authorised including saying "Alert", displaying an Alert card from a bidding box or 'knocking' on the table.


 * Antipositional : A call is antipositional if it tends to make the "wrong" partner the declarer. If West opens the bidding, it may be best for South to declare a North-South contract, so that West will have to play from his high cards on opening lead. This positioning may protect South's tenaces. In that case, a call that will make North declarer is antipositional. See wrongside.


 * Appeal : In tournaments, to appeal is to request that a committee review a ruling made by a director.


 * Approach-forcing : A principle, first used in the Culbertson system, that has survived in modern bidding. The original idea was to abandon the indiscriminate notrump bids that characterized auction bridge in favor of a slower exchange of information via suit bidding.


 * Arrow : A marker, usually a large card with an arrow on it, that shows which direction is treated as North at a table in a duplicate event.


 * Artificial : 1) A call that is not natural, one that carries a coded message not necessarily related to the call's (or to the prior call's) denomination.
 * 2) A bidding system that contains many such calls.


 * Asking bid : A bid that, by prior agreement, requests information about a feature of partner's hand: for example, number of controls, suit length, or control of a particular suit.


 * Attacking lead : A lead that instigates an active defense; often, the lead of an honor from a sequence, or a forcing defense.


 * Attitude : A defender's desire, or lack thereof, for his side to continue playing a suit. By means of signals, defender encourages or discourages the continuation of the suit.


 * Auction : 1) See bidding.
 * 2) Auction bridge, an older form of bridge, replaced by Contract bridge.


 * Autobridge: A non-digital game for one person, designed to teach bridge (see image).


 *  Automatic squeeze : A squeeze position that succeeds against either opponent. Contrast with positional squeeze.


 * Average : In matchpoint scoring, an "average" that score awarded to both pairs when for some reason they cannot complete the board and neither pair is at fault; each pair is given a score equal to its own average on all other boards in that session. If one pair is at fault, it receives an "average-minus" (often its average minus 20%). The pair not at fault might receive "average-plus," or average plus 20%. Also see IMP pairs, where "average" refers to the datum used in scoring.


 * Avoidance play : A play designed to keep a particular defender off lead, often to prevent the lead of a suit through a tenace position in either declarer's hand or dummy.

B

 * Back in : To make a partnership's first bid, having previously passed. For example, in 1HS undefined - (P) - 1NT - (P); 2 - (bl), the doubler has backed into the bidding.


 * Backward finesse: A combination of two finesses in a suit such that the first finesse is "backward" (that is, the reverse of the normal direction).


 *  Balance : To keep the bidding open when it is about to be passed out at a low level. For example, if the bidding goes 1HS undefined - (P) - P - (1NT), the 1NT bid is a balancing action. The balancing bid is often made with a hand of substandard strength, to prevent the opponents from buying the hand too cheaply.


 * Balanced hand : A hand is said to be balanced if it has a distribution of 4-3-3-3, 4-4-3-2, or 5-3-3-2 (Also defined as "no voids, no singletons, and at most one doubleton"). Notrump bids, when natural, generally denote balanced hands.


 * Bar : To prevent a player from making a bid, either by a penalty caused by an irregularity, or because partnership agreement requires a pass in a given situation. In either case, the player is said to be "barred."


 * Barometer scoring : In a duplicate event, the posting of contestants' running scores after each round. Knowledge of the current standings often adds excitement to the contest, and can affect the strategies adopted by those in a position to win the event.


 * Bath coup: A holdup by declarer, to prevent an opponent from continuing a suit. In the classic position, declarer holds SS undefinedAJ2 and West leads SS undefinedK from SS undefinedKQ1098. By playing the 2 on West's K, South makes it impossible for West to continue spades without giving South a free finesse.


 * Below the line : In rubber bridge, points awarded for tricks bid for and taken are recorded "below the line." These are the points counted towards game. See Above the line.


 * Bermuda Bowl : The cup awarded to the winner of the international team championship, the most prestigious award in bridge. Also, the championship contest itself.


 * Bid : A declaration of both level and denomination that suggests a final contract. Some bids are instead used as conventions: they carry coded messages and are not normally intended as final contracts.


 * Bid out of turn : A bid erroneously made when it was another player's turn to bid. Subject to penalty.


 * Biddable suit : A suit that is, systemically or by partnership agreement, long and strong enough to be bid.


 * Bidding : The first phase of a deal, when players establish the final contract by making a series of bids.


 *  Bidding box : A box, physically attached to a table, that contains cards with bids printed on them. By selecting and displaying a card, a player can bid without speaking. Silent bidding removes one source of unauthorized information from the game.


 * Bidding space : The number of steps available in an auction (see Useful space principle), or the number of steps consumed by a bid. The sequence 1 - 1 consumes only one step, whereas 1 - 2 consumes four steps. Because alternative bids are skipped, it often happens that the more steps a bid takes up, the more specific meaning it carries.


 *  Bidding system : The complete set of agreements and conventions assigned to  bids, and sequences of bids, by a partnership.


 *  Blackwood convention : Popular bidding convention in contract bridge, used to determine number of partner's aces/kings to evaluate for slam bids.


 * Blank : 1) (Adjective) Unprotected by other, usually lower cards in the same suit: "I held the blank king of spades."
 * 2) (Verb) To discard in such a way as to leave a card unprotected: "She blanked the king of spades."


 * Blitz : (Slang) A win by the widest possible margin.


 * Blocked : (Adjective) A suit that cannot be run without an entry in another suit is blocked. If North holds AK and South holds QJ10, South cannot cash all three diamond tricks without an entry in another suit. The diamonds are blocked.


 *  Board : 1) A device that keeps each player's cards separate for duplicate bridge.
 * 2) The dummy's hand. For example, "You're on the board," means "The lead is in the dummy."
 * 3) See deal.


 * Board-a-Match: A form of scoring for team events, similar to matchpoint scoring in pair games, in which every deal carries equal weight. For example, a team receives 1 point if its score is higher than the other team's on a board, 1/2 point for a tie, and 0 points if its score is lower. Now less common than IMP and victory point scoring.


 * Body : Intermediate cards such as the 9, 8 and 7, that contribute to a suit's trick-taking potential.


 * Bonus : In bridge scoring, beyond points for bid tricks taken, which are awarded for making a contract, the additional points awarded for making a doubled contract, or for making doubled or redoubled overtricks. There are different bonus amounts at the partscore, game, small slam, and grand slam levels. The size of most bonuses depends on the vulnerability. Bonus amounts are different in rubber bridge and duplicate bridge. See Bridge scoring.


 * Book : 1) (Noun) The basic six tricks that must be taken by the declaring side. The first six "book" tricks are always assumed and are not taken into account in bidding or scoring. Thus, a contract at the 1-level commits declarer to take at least 7 (that is, 6 + 1) tricks, and provides trick points only for the trick above book. The term apparently originated from the whist practice of arranging the first six tricks into a stack called a "book."
 * 2) (Noun) The number of tricks that the defensive side must take so as to hold declarer to his contract. If the contract is 4SS undefined, defenders' book is 3.
 * 3) (Verb, usually passive) Slang. As declarer, to have lost the maximum number of tricks without being set. At 4SS undefined, declarer is "booked" when he has lost three tricks.


 * Bottom : At matchpoint scoring, the lowest possible score on a board. Also, zero.


 * Bracket : A group of entries in a tournament that will eventually have one winner. The grouping is often done on the basis of master points.


 * Break : 1) (Noun) The distribution of cards in a suit between two (often unseen) hands: "I got a 4-1 spade break." An even break occurs when the cards are distributed evenly or nearly so, such as 3-3 or 4-2. A bad break, connoting a distribution that is difficult to handle, suggests an unexpectedly uneven distribution, such as 5-1 or 6-0. See distribution.
 * 2) (Verb) To be divided between two hands. "The spades broke 3-2."
 * 3) (Verb) To lead a particular suit for the first time during a particular deal.
 * 4) (Verb) Slang. To play for and find a particular distribution, usually the most favorable. "I broke the spades."


 * Bridge maxims: A compilation of short "laws", "rules" and rules-of-thumb advice; often, not always, valid.


 * Bridge World, The: A monthly magazine, the oldest continuously published periodical concerning contract bridge, and the game's most prestigious technical journal.


 * Broken sequence : A sequence of honor cards, one or more of which is missing, for example AQJ.


 * Business double: A penalty double. Contrast with various competitive and informatory doubles such as takeout double and negative double.


 * Bust : (Slang) A very weak hand. Sometimes paired with the name of a long suit: for example, "club bust" to denote a hand with long clubs and very little high card strength. See also Yarborough.


 * Busy : A card that is needed for some purpose is said to be busy. For example, cards that a defender is trying to preserve while declarer executes a squeeze are "busy." Contrast with idle.


 * Butler: A method of overall scoring in duplicate bridge where every result is subtracted from a datum (average or median) score and converted to IMPs using a table defined by the WBF.


 * Bye : 1) A round of an event during which a team or pair is not scheduled to play.
 * 2) A location, such as a chair or stand, where boards are kept when not in use during an event.

C

 * Caddy: A non-playing person designated to move boards between tables during a tournament.


 * Calcutta : 1) See Cross-Imp scoring
 * 2) A tournament in which bettors bid on participating pairs or teams. The proceeds from the auction are distributed partly as prizes to the top finishers, partly to the bettors who successfully bid on them. A pair or team can typically buy an interest in itself.


 * Call : Any bid, pass, double, or redouble in the bidding stage.


 * Canape : An approach to bidding in which a player bids his shorter suit prior to his longer suit. A feature of the Blue Team Club and the Roman Club.


 * Captain : 1) The partner who makes the decision for a partnership in certain bidding situations, such as ace-asking sequences.
 * 2) The person representing and/or coaching the team; can be playing or non-playing captain (NPC), i.e. participating in the play or not.


 * Card reading : The act of determining the distribution of cards in unseen hands, and the location of high cards therein, by analyzing the bidding, play and other clues.


 * Carding : The defensive signaling used by a partnership.


 * Carryover : In team events, a portion of a score from an earlier session between two teams that is applied to a subsequent match between the same teams.


 * Cash : To take a trick with a card that is currently the highest in the suit, thought certain to succeed, or to take all available winners in a suit.


 * Cavendish variation : A version of Chicago, with declarer's side not vulnerable on the second and third hands, as in the standard version.


 * CBF: Canadian Bridge Federation.


 * Change of suit : A bid in a new suit, as 1SS undefined in the sequence 1 - 1HS undefined; 1SS undefined.


 * Chicago : A form of bridge in which a rubber is completed every four deals, and the vulnerability is different in each of those deals (dealer's side is vulnerable on the second and third deals). The scoring and sequence of dealer and vulnerability used in duplicate bridge are derived from those used in Chicago bridge. Chicago is said to have been devised by commuters who played bridge on daily train journeys, where the time available for play was limited by the length of the trip.


 * CHO : Centre Hand Opponent; a slang, uncomplimentary term for one's partner, or partners generally.


 * Chunky : A suit with enough honor strength to play well unaided by partner's cards (but not solid) is chunky. Normally said of four-card suits. AQJ10 is a chunky suit; AQ96 is not chunky.


 * Claim : A statement by declarer about how the remaining unplayed tricks will be won or lost. Normally the claiming player exposes his hand and describes the sequence of play for the remaining tricks (but such plays as finesses, unless already proven, are disallowed). A claim is best made only when the play of the rest of the hand is obvious. Claims are often unadvisable: apart from the possibility of a mistaken analysis, it can take longer to explain the line of play than to play it. See also concession.


 * Clear a suit : Knock out an opponent's high-card control of a suit, or unblock one's own high cards.


 * Closed hand : Declarer's hand (as distinct from the dummy, which is faced or open).


 * Closed room : In a team match, a room where two of the pairs compete, and in which spectators are not allowed.


 * Coffeehousing: Making improper remarks to mislead the opponents, or asking improper questions designed to suggest a defensive play.


 * Cold : A contract that a player cannot fail to make is cold.


 * Combinaton : 1) See suit combination.
 * 2) finesse: See double finesse in finesse.


 * Combination play : A line of play that offers more than one chance to take additional tricks: for example, playing to drop an honor in a longer suit and then finessing for an honor in a shorter suit.


 * Come-on : A defensive signal that encourages partner to continue a suit, usually by means of the rank of the card used to follow suit.


 *  Comic notrump : A notrump overcall that shows a weak hand with a long suit, to which the overcaller can escape if doubled. Also known as Gardener 1NT.


 * Communication :
 * 1) The placement of the lead in one or the other of the two partnership hands, so as to make a subsequent lead from the more advantageous hand.
 * 2) The means of conveying a message to partner via the bidding. The only legal means of communication is through the calls themselves, rather than by the use of hesitations or mannerisms. Often generalized as communications in both senses.


 * Comparative scoring : The method of scoring used in matchpoint or Board-a-Match events. The metric used is not the number of points earned on a particular deal, as it is when using quantitative scoring, but the number of pairs that have been out-scored.


 * Competitive auction : A bidding sequence which involves both partnerships. Also, competitive bidding.


 * Concession : A statement by a player as to the number of remaining tricks that he must lose. (See claim.)


 * Condone: To act after an opponent's irregularity without arranging for the penalty specified in the Laws to be applied.


 * Congratulatory jack: The unnecessary play (by follow-suit or by discard) of a jack following partner's exceptionally successful action. More often used by the defense, but possible as a play from dummy.


 * Constructive : 1) Bidding that is aimed at reaching a side's optimum contract, as distinct from calls intended to interfere with the opponents' bidding.
 * 2) Constructive raise: by partnership agreement, a single raise of a major suit opening that shows more strength than usual.


 * Contract : 1) The statement of the pair who has won the bidding, that they will take at least the given number of tricks. The contract consists of two components: the level, stating the number of tricks to be taken (in addition to the book tricks), and the denomination, denoting the trump suit (or its absence in a notrump bid). The last bid in the bidding phase denotes the final contract.
 * 2) Short for Contract Bridge as opposed to other forms of bridge, such as Auction bridge.


 * Control : 1) A feature of a hand which prevents the opponents from taking immediate tricks in a suit. Aces are termed "first-round" controls and kings are termed "second-round" controls. In trump contracts, voids are also considered first-round controls and singletons second-round controls.
 * 2) (Said of trump contracts) Declarer's ability to manage the trump suit successfully. To lose control usually means being forced to shorten one's trumps so much that the opponents can subsequently control the play of the hand.


 * Control-bid : A bid that shows control of a particular suit. Often a cue bid, but not all cue bids are control-bids.


 *  Convention : An agreement between partners on the meaning of a bid or sequence of bids, such that the meaning is not necessarily related to the length and strength of bid suits. Many bidding conventions are artificial; see, for example, Bridge conventions (slam seeking). Compare with Treatment. Also, an agreement that a particular defensive play has a special meaning.


 * Convention card : A form filled out by a partnership that shows the bidding and play conventions being used. Normally used during tournaments.


 * Convert : To change the effect of a call. For example, passing partner's overcall of 2 when playing Michaels cue bids converts the overcall from a request to bid a major suit to a contract of 2. There are many other applications: for example, to pass partner's takeout double is to convert it to a penalty double.


 * Correct : In the bidding, to choose (usually) partner's first bid suit; in that case, a correction is equivalent to a preference.


 * Count : 1) (Noun) The number of cards held in a suit or suits, usually said of an opponent's hand.
 * 2) (Verb) To determine, by inference or by follow-suit, the number of cards held in a suit by an opponent.
 * 3) (Noun) In squeeze play, the number of tricks that declarer must lose before the squeeze can function.


 * Count signal : A defensive card play that shows whether the player has an even or odd number of cards in a suit.


 * Coup: 1) Any extremely skillful play.
 * 2) The shortening of trumps in (usually) declarer's hand to bring about a position in which the lead of a side suit will cope with the defenders' trump holding.


 * Coup en passant: The lead of a side suit through an opponent who holds a higher trump so as to score a lower trump in the third hand.


 * Coup without a name: See Scissors coup. "Coup without a name" is an earlier term for the coup, conferred by Ely Culbertson.


 * Cover card : A card (honor or extra trump) which is known to compensate one of partner's losers; for example, a king in trumps covers partner's trump loser.


 * Crack : (Slang) To make a penalty double.


 * Crocodile coup: On defense, second hand's play of a higher card than apparently necessary, so as to obtain the lead. The play is intended to prevent fourth hand from being forced into the lead to make a return favorable to declarer. The name suggests a crocodile opening its maw to swallow up partner's winning card.


 * Cross : To enter the opposite hand. Normally used of dummy or declarer's hand: "He crossed to dummy in diamonds."


 * Crossruff: A playing technique in trump contracts, where extra tricks are gained by ruffing in both hands alternately.


 * Cross-IMP scoring : A form of IMP scoring in pairs tournaments, where each pair's score is determined as an (averaged) sum of differences to all other scores (rather than to a single datum score). Also known as X-Imps or Calcutta.


 *  Cue bid : 1) A bid of the opponents' suit in a competitive auction. Usually a conventional, forcing bid that shows strength or an unusual hand, or a particular distribution.
 * 2) A bid that shows a control in a suit (usually with an Ace or King, sometimes with a void), but does not indicate length or strength in the suit otherwise. See control bid. Partnership agreements indicate when in an uncontested auction a bid is considered a cue bid. Usually used in exploring for a slam contract (see Bridge conventions (slam seeking)), or for showing stoppers needed for a notrump game.


 * Culbertson system : The earliest dominant bidding system, developed by Ely and Josephine Culbertson. Its principal features were an approach-forcing bidding style, four-card majors, strong two-bids and the use of an honor trick table to evaluate hand strength.


 * Curse of Scotland: The 9. The origin of the term is not known with certainty.


 * Cutthroat bridge: A form of three-handed bridge.

D

 * Danger hand : (Usually in reference to the defenders.) An opponent who, if he obtains the lead, can damage declarer's prospects.


 * Datum : The mean or median of raw scores on a deal. The datum is used as a basis for calculating IMPs for the participating teams or pairs. The datum may be trimmed by removing extreme scores at either end of the distribution, a procedure whose effect on a mean or on a median depends on the degree of skewness in the raw scores.


 * Dead : (Usually in reference to the dummy.) A hand that has no card of entry.


 * Deal : The set of particular 52 cards as distributed to each player, and the bidding and play based on those cards. Also called board or hand.


 * Dealer : The player who deals the cards and bids first. In duplicate bridge, cards are dealt only at the outset of the session and the deal is preserved during the session by the use of boards. The dealer for each board is determined by a mark that indicates the dealer's position on the physical board.


 * Deck : The 52 cards used in bridge.


 * Declaration : The contract in which a hand is played.


 * Declarative-Interrogative: See D-I.


 * Declarer : Of the pair that makes the final bid in the auction, the player who first bid that call's strain. The declarer plays the cards in his own hand as well as dummy's cards.


 * Deep finesse: A finesse against two or more cards.

 * Defenders : The pair that tries to defeat the contract.


 * Defense : Declarer's opponents or their line of play.


 * Defensive bidding: A bid or sequence of bids designed to hinder the opponents' bidding, including sacrifices.


 * Delayed : Postponed, as the jump preference in the auction 1HS undefined - 1SS undefined; 2 - 3HS undefined. Many bids have a different meaning depending on whether or not they are made at the first opportunity.


 * Denomination (also 'Strain') : Component of a bid that denotes the proposed trump suit or notrump. Thus, there are five denominations (see Rank (2)).


 * DEPO : Acronym for Double Even Pass Odd. Conventional method for bidding over interference with Blackwood.


 * Deschapelles coup: On defense, the lead of an unsupported honor so as to create an entry for partner.


 * Develop : To establish tricks in a suit, usually by forcing out the opponents' stoppers.


 * Devil's coup: In the endgame, the play of a side suit through a defender to create an overruff and a subsequent trump finesse.


 * D-I : (Abbreviation of Declarative-Interrogative.) 4NT as a general slam try that asks partner to show features. D-I is incorporated in several bidding systems, including Neapolitan, Blue Team Club and Kaplan-Sheinwold. 4NT D-I is distinguished from Blackwood by means of the bidding context.


 * Direction : A player's position at the bridge table (North, East, South or West).


 * Direct position: Usually said of a bid that is made immediately following RHO's bid. Contrast with balance.


 * Director : Referee (in duplicate bridge). The director enforces the rules, assigns penalties for violations, and oversees the progress of the game. The director is also responsible for the final scoring. At a tournament there may be several directors, reporting to a Head Director. In ACBL-sponsored events, a director's ruling as to bridge fact may be appealed; a ruling as to discipline, so as to maintain an orderly event, may not.


 * Discard : 1) (Verb) To play a card that is neither of the suit led, nor trump, and that therefore cannot win the trick.
 * 2) (Noun) The card so played.

come-on]].
 * Discouraging card : A carding signal that discourages partner from leading a particular suit. Contrast with [[#come-on|


 * Discovery play : A play, either by declarer or by the defense, intended to obtain information about the location of other cards.


 *  Distribution : 1) The number of cards in each suit in a player's hand, usually expressed as a series of 4 numbers. A distribution of 4=6=2=1 means 4 spades, 6 hearts, 2 diamonds, and 1 club. Also called a "Hand pattern".
 * 2) The number of cards in one suit as distributed in four (or two) hands, expressed as series of four (or two) numbers.
 * 3) The degree to which a player's hand consists of particularly long and short suits.


 * Distribution point: A measure of a hand's strength due to the length or shortness of suits. See Hand evaluation.


 * DONT: A conventional defense to notrump opening bids.


 * DOPE: Acronym for Double Odd Pass Even. Conventional method for bidding over interference with Blackwood.


 * DOPI: Abbreviation of Double 0 Pass 1. Conventional method for bidding over interference with Blackwood. Pronounced "dopey."


 * Double : A call that increases penalties if the opponents fail to make their contract, but that increases the bonuses if they make it. A player can double only a contract bid by the opposition. Often used conventionally for purposes other than to increase the penalties.


 * Double dummy : (Adjective or adverb.) Said of a play that is made as though all four hands were visible. Compare with single dummy.

 * Down the line : To bid the higher of two adjacent suits before the lower. For example, of two five-card majors, the spade suit is normally bid before the heart suit. Contrast with Up the line.


 * Draw: To extract, usually trumps. To remove the opponents' trump cards is to "draw trumps."


 * Drive out: To force a stopper from an opponent's hand, usually by repeatedly leading the suit.


 * Drop : 1) (Verb) To fall under a higher card: "The SS undefinedQ dropped under the SS undefinedK."
 * 2) (Noun) That occurrence itself: "He played for the drop instead of finessing."


 *  Duck : A play technique in which a player does not immediately play a card that might take a trick, but plays a small card instead.


 * Dummy: 1) The partner of the declarer, whose cards are placed face up on the table and played by the declarer. Dummy has few rights and may not participate in choices concerning the play of the hand.
 * 2) The dummy's hand as exposed on the table.


 * Dummy play : The play of the hand by declarer. The apparent contradiction is due to the fact that declarer plays both declarer's cards and the dummy's.


 * Dummy reversal: A playing technique in trump contracts that gains extra tricks by ruffing in the hand that began with the longer trumps.


 * Dump : To lose a match deliberately, usually so as to assist another team or pair in the event. A subject of considerable controversy in the 1990s and beyond.


 *  Duplicate bridge: A form of bridge where every deal is played at several tables, by several pairs, and their scores on each deal are subsequently compared. At minimum, two tables (four pairs) are required for a duplicate bridge match. Each entry might be a pair, or a team consisting of two or more pairs; the type of scoring varies accordingly. The hands of each deal are kept in metal or plastic containers called boards that are passed between tables.


 * Duplication of values : The possession of values in a single suit, in both partners' hands. Usually said of high card values in one hand paired with a singleton or void in partner's hand. Such a holding is normally undesirable: SS undefinedKJ9 facing a void is much less useful than SS undefinedKJ9 facing SS undefinedQ4.

E

 * Eastern Scientific : A bidding style that developed in the Eastern United States, particularly the New York region. It is characterized by five-card majors with a forcing one notrump response and limit raises, strong notrump with Jacoby transfers, and strong (but not game forcing) two-over-one responses.


 * EBL : European Bridge League, the official organising body of bridge in Europe.


 *  EBU : English Bridge Union, the official organising body of bridge in England.


 * Echo : The play of first the higher, then the lower of two cards of the same suit on separate tricks to encourage or, by prior agreement, to discourage (see upside-down signals) partner's continuation of a suit; or to signal possession of (normally) an even number of cards in the suit at the time the higher card is played.


 * EHAA: Acronym for Every Hand An Adventure, a bidding style that emphasizes very weak notrump opening bids (often 10-12 HCP), four-card majors, and undisciplined weak-two bids.


 * Eight ever, nine never: A Bridge maxim that advises players when to finesse for a missing queen. With eight cards in the suit, always ("ever") finesse; but with nine cards, never finesse, rather play for the queen to drop under the play of the ace and king. Experienced players often ignore this advice in favor of considerations such as the danger hand, combination play, and the known or inferred distribution of other suits.


 * Elimination : The removal, by playing a suit or suits, of safe exit cards from defenders' hands, normally in preparation for an endplay. The classic (but not the only) example is to leave an endplayed defender with the choice of conceding a ruff and discard or giving declarer a free finesse.


 * Elope : To win a trick by ruffing with a trump lower in rank than an opponent's trump. The Coup en passant is an example of an elopement.


 * Encrypted : An agreement that the meaning of bids or card signals may change as more information about a deal becomes available. For example, when declarer shows out of a suit, the defenders can tell whether the rank of West's lowest remaining card in the suit is even or odd (and declarer probably does not have that information). The defenders might have agreed that if West's lowest remaining card is even, normal attitude signals will be in effect, but if it is odd, upside-down signals will be used. In such a case, the defenders' agreement is encrypted.


 * Ending : The layout of the cards when just a few tricks remain to be played. In a "four-card ending," each player has four cards left. Such positions can be of special interest because squeezes and other endplays tend to occur near the end of the play.


 * Endplay: A play which forces a particular opponent to win a trick, so that that opponent must then make a favorable lead. That player is said to be "endplayed". Normally, the player who is endplayed is a defender. Although the word implies that the play occurs toward the end of a hand, it often occurs earlier, and in exceptional cases the opening leader can be said to be "endplayed at Trick One."


 * Enter : 1) To win a trick in the opposite hand, thereby giving it the right to lead to the next trick.
 * 2) To make the first call for a partnership after the opponents have bid.
 * 3) To join a bridge competition.


 * Entry: 1) A card that allows a partnership to win in one hand after leading from the other. Entries are vital to communication.
 * 2) A seating assignment in a bridge competition. Entries designate the participants' initial table number, direction at that table, and (if applicable) section.


 *  Entry-shifting squeeze : A squeeze in which the declarer decides whether to overtake the squeeze card or to let it hold the trick, depending on LHO's play.


 * Entry squeeze : A squeeze that puts pressure on a holding that interferes with declarer's entries.


 * Equal level conversion : An agreement concerning rebids after take-out doubles. Traditionally, the bid of a new suit by the player who has made a take-out double is considered forcing. Under the equal level conversion agreement, the bid of a new suit by the doubler is not forcing if it is at the same level as advancer's bid. So, equal level conversion means that in the sequence 1SS undefined - (Dbl) - P - (2); P - (2HS undefined), 2HS undefined is considered non-forcing.


 * Equals : Cards in one hand that are adjacent in rank and thus have equal trick-taking power.


 * Escape suit : A long suit to which a bidder can escape if necessary or desirable. The bidder of a comic notrump might run to his long suit if doubled.


 * : To make winners of the remaining cards in a suit by playing or forcing out higher cards.


 * Even : 1) A split with the same number of cards in each hand. A 2-2 split is an even split.
 * 2) Of the number of cards in a suit found in a hand: two cards, four cards, and so on.


 * Event : A duplicate bridge contest.


 * Exclusion bid : A bid, such as 2 in the Roman Club system, that shows length in all suits except the one named.


 * Exclusion Blackwood : An agreement that responder to a Blackwood bid will show the number of aces held outside a particular suit.


 * Exit card : A card that is used to put a different hand on lead, normally to avoid making a self-destructive lead in another suit.


 * Expert : A term used to describe someone who plays bridge better than the person using the term.


 * Exposed card : A card whose suit and rank become known through an irregularity. An exposed card may be subject to penalty.


 * Extra values : Values (in the form of High card points, shortage or cover cards), which are in addition to the values that a player has promised so far in the bidding.

F

 * Face : 1) (Noun) The front of a card; the side that displays its suit and rank.
 * 2) (Verb) To turn a card so that its face is visible to other players.


 * Face card : A king, queen, or jack. (Compare with honor.)


 * Factoring : The adjustment of matchpoint scores to correct for dissimilar conditions. For example, a game played with a Mitchell movement might have an extra N-S pair, causing a bye round for N-S. The top is therefore lower for N-S pairs than for E-W pairs, and the N-S scores are multiplied by a fraction (or "factor") to make them commensurate with the E-W scores.


 * Fall : To be captured by a higher card. See drop.


 * False preference : A return to partner's first-bid suit despite a longer holding in the second suit. Usually intended to give partner an opportunity for another bid.


 * False sacrifice : See Phantom sacrifice.


 * Falsecard : A card played with the intention of deceiving an opponent as to one's true holding. Also, the act of making such a play.


 * Fast arrival : A style of bidding under which the fewer bids used to reach a contract (usually said of game contracts), the weaker the bidder's hand. Fast arrival holds that 1SS undefined - 2; 2SS undefined - 4SS undefined is weaker than 1SS undefined - 2; 2SS undefined - 3; 3NT - 4SS undefined. Compare with slow arrival.


 * Feature : An honor or shortness in a suit. Conventional bids such as splinter bids or D-I are intended to show or elicit features.


 * Fert: (Slang) Short for "fertilizer," a very weak opening bid. A systemic Treatment in strong pass systems.


 * Field : All the players in a bridge event, as in "with the field" to describe an action that most players will take, and "against the field" to describe an unusual action.


 * Field a psych: Deciding correctly that partner has psyched in the absence of a call that reveals the psych. Sometimes used when that decision is made on the basis of unauthorized information or an undisclosed partnership understanding.


 * Fillers : Mid-rank cards that strengthen a suit. See body.


 * Final contract : The last bid made on a hand.


 *  Finesse : A technique that attempts to gain a trick or tricks by taking advantage of a favorable lie of the opponents' cards.


 * Fit : 1) A long suit (usually 8 cards or more) in two combined hands, that might be used as trumps.
 * 2) General term for two hands that are productive together (i.e., that have at least one fitting suit and few wasted values). Compare with Misfit.


 * Fit-bid : A bid in a suit that shows length and strength in the bid suit plus a fit for partner's suit. Jump shifts in competition are often defined as fit-bids. Compare with Fragment bid and Mixed (definition 2).


 * Five-card majors : An agreement that an opening bid in spades or hearts promises at least five cards in the suit. The alternative agreement is four-card majors.


 * Fix : 1) (Noun) An undeservedly poor result, usually caused by an opponent's error or eccentric play that happens to turn out well.
 * 2) (Verb) To be the victim of a fix: "We were fixed on Board 8."


 * Flat: 1) Flat hand: A hand that lacks distributional features such as a singleton, a void, or a very long suit. Often, 4-3-3-3 distribution.
 * 2) Flat board: A deal in duplicate bridge that results in scores across the field that are identical, or nearly so.


 * Float : 1) To be followed by two or three passes. For example, West's spade bid "floated around" to South in 1SS undefined - (P) - P.
 * 2) To fail to cover the card led, usually by two consecutive hands. "South floated the SS undefinedQ to East."


 * Flower movement : An adaptation of the Howell movement in which the players, rather than the boards, progress regularly from table to table. Also known as "Endless Howell."


 * Follow suit : To play a card of the same suit as the one that was first led to the trick. Failure to follow suit when one can do so constitutes a revoke.


 * Force to : To bid with the intention of causing the bidding to proceed to a particular level. For example: "In this auction, 2 forced to game," or "My reverse forced to the three-level."


 *  Forcing bid : A bid that, by partnership understanding, requires the bidder's partner to make another bid. A forcing bid is not necessarily a strong bid. It is legal to pass partner's forcing bid, and players occasionally do so if they believe it advantageous on a given hand, but it is damaging to partnership confidence.


 * Forcing defense : The lead and subsequent continuation of a suit that the defenders believe declarer will have to ruff in the long trump hand. The strategy is to shorten declarer's trump holding so as to leave the defenders in control of the hand. See Tap.


 * Forcing notrump : An agreement that a 1NT response to a 1HS undefined or 1SS undefined opening is a forcing bid.


 * Forcing pass : A pass in a competitive auction that requires partner to either make another bid or to double the opponents' current bid. Experienced partnerships often have agreements about differences in strength shown by bidding immediately, as distinct from making a forcing pass and then bidding over partner's double (pass and pull).


 * Fork : A tenace.


 * Fouled board : A board whose cards are not distributed as they were when first played, due to returning the cards to their slots erroneously.


 * Four-card majors : An agreement that an opening bid of 1HS undefined or 1SS undefined promises four cards in the suit bid. The usual alternative is five-card majors. The four-card major agreement was standard during the first four decades of contract bridge, but has since given way to five-card majors in "standard" systems such as 2/1 game forcing and Standard American. It is used in the Blue Team Club and EHAA.


 * Four-deal bridge : See Chicago.


 * Fourth : 1) A player needed to complete a table, usually said of rubber bridge.
 * 2) Of four-card suit length: for example, Q987 is referred to as "queen-fourth."


 * Fourth hand : The fourth player with an opportunity to bid, or to play to a trick.


 * Fourth suit forcing: 1) The initial use of a bid of the fourth suit as forcing to some level.
 * 2) An agreement that the partnership's bid of the fourth suit, in addition to its forcing nature, is possibly artificial.


 * Fragment bid : A second-round jump bid (usually a double jump) that by agreement shows a fit with partner's last-bid suit and shortness in another suit. Under this agreement, in 1 - 1HS undefined; 3SS undefined the bid of 3SS undefined is a fragment bid, showing a fit for hearts and a singleton or void in diamonds. The suit of the fragment bid is often three cards long. Compare with splinter bid.


 * Freak : (Also, "freak hand.") A hand with a very long suit or suits. Most would regard a hand with two six card suits as a freak.


 * Free bid : A bid that is made when a pass would still allow partner to make a bid. Normally used of a bid that is made after partner has opened the bidding and RHO has overcalled. Compare with Negative free bid.


 * Free finesse : A position in which a player leads up to an opponent's tenace, solving that opponent's possible guess. The term is normally used when the player is forced to make that lead.


 * Frozen: A frozen suit is one that neither side can play without damage to its own holding in the suit. Declarer can sometimes duck the defense's lead to freeze the suit. The following suit is frozen:

G

 * Gambling 3NT: An opening bid of 3NT. The bidder hopes to make the contract by means of a long minor suit rather than by a preponderance of high cards.


 * Game : A contract, bid and made, worth 100 points or more. The undoubled game contracts are 3NT (40 for the first trick + 30 each for the second and third); 4HS undefined and 4SS undefined in the majors (4 tricks × 30 points per trick); 5 and 5 in the minors (5 tricks × 20 points per trick). Game can also be made via a doubled or redoubled contract: e.g., 2SS undefined doubled is worth 2 × (2 tricks × 30 points per trick) = 120 points. The pair bidding and making the game is awarded a bonus. See Bridge scoring.


 * Game force : A bid that asks partner not to pass before the partnership's bidding has reached game (or the opponents have been doubled at a level high enough to compensate). Some treatments relax the requirement: for example, the agreement that in the sequence 1M - 2m, the 2m response is a game force unless the suit is rebid. So, in 1SS undefined - 2; 2HS undefined - 3, 3 would cancel the game-forcing message of the 2 bid.


 *  Game try : A bid, often in a side suit, which invites the partner to bid a game if he has extra values in the context of the prior bidding. A help-suit game try is made in the suit where one hopes that partner holds cover cards. A short-suit game try is made in the suit where one hopes that the partnership has no duplication of values.


 * Good : Said of a card or cards that have been established.


 * Goren system : A system of bidding, dominant in the United States from the 1940s through the 1960s, based on the Culbertson system. The principal difference between the two systems was in hand evaluation: Culbertson used honor tricks to assess a hand's strength whereas Goren used High card points.


 * Goulash: A style of dealing, usually in rubber and Chicago games, where the cards are not thoroughly shuffled between deals and are dealt in groups. It results in "wild" card distributions.


 * Grand coup : A trump coup in which the cards ruffed in the long trump hand are already winners.


 * Grand slam: A contract to win all thirteen tricks. Bidding and making a grand slam scores significant bonus points.


 * Grand slam force (GSF): A method of determining whether the partnership holds the top trump honors when the bid of a grand slam is a possibility. In its original form, the GSF was initiated with a bid of 5NT, asking partner to bid a grand slam with two of the top three honors in the trump suit. Depending on the prior bidding, other bids are often used in place of 5NT, and there is a variety of schemes for responding to the GSF. See Josephine.


 * Grosvenor gambit: A play that creates no direct advantage and might lose. Its principal features are that an opponent will not suspect that such an inept play has been made, and that once the opponent realizes what has occurred, he will be frustrated and angry (and therefore less effective) during subsequent hands. The ploy was first described in a satiric story by Frederick B. Turner in the June 1973 issue of The Bridge World.


 * Guard: A holding that prevents an opponent from taking a trick or tricks. See stopper, guard squeeze.

H

 * Hand : 1) The cards held by one player.
 * 2) The player holding the cards, as in "Third hand bid 1SS undefined."
 * 3) The entire deal.


 * Hand pattern: See distribution.


 * Help-suit game try: A bid of a side suit after a single raise, hoping to reach game. For example, after 1HS undefined - 2HS undefined, opener might rebid 3 with a side club suit. The bid tells partner where high cards will be most helpful, and requests partner to take positive action with strength in that suit. Otherwise, the bid requests partner to sign off (in this example, by bidding 3HS undefined). See short-suit game try and game try.


 * Hesitation: A brief pause before a bid or play, considered somewhat shorter than a Huddle.


 * High-low signal : See Echo.


 * High card : 1) An honor card.
 * 2) The highest ranking card in a suit at any point during the play.


 *  High card points  (HCP): A method for evaluating a hand's strength, where every honor card is assigned a numeric value. See Hand evaluation.


 * Hold : 1) To keep declarer to a particular number of tricks, usually the number required to make the contract.
 * 2) To have in one's hand a particular card or set of cards.
 * 3) (Of a card) To win a trick although a higher card is outstanding.


 *  Hold up : 1) (Verb) To defer taking a winning card until an advantageous point in the hand, usually in reference to tricks that the opponents have led to. There are various purposes for holding up a winner, but it is frequently done to force the opponents to use their entries too soon.
 * 2) (Noun) The act of holding up a winner.


 * Holding : 1) The cards in a player's hand at a particular point in the play (often, at the start of the play).
 * 2) The cards in a specific suit in a player's hand.


 * Honor card (spelled honour where UK English is dominant): An ace, king, queen, jack or ten.


 * Honor bonus : At rubber bridge and Chicago, a scoring bonus. The bonus is 100 points for one hand holding four of the five trump suit honors. The bonus is 150 points for all five trump suit honors, or all four aces in a NT contract.


 * Honor tricks : A method of hand evaluation used in the Culbertson system, which assigns point values to honors and combinations of honors. For example, AK is two honor tricks, AQ is 1 1/2 honor tricks, KQ is 1 honor trick, and so on.


 * Hook : (Slang) To finesse, or the finesse itself.


 * House player : An employee of a bridge club who is available as a fourth.


 * Howell movement : A plan for determining which pairs will meet on a given round in a matchpoint game, and which boards they will play.

 * HUM: Acronym for Highly Unusual Methods.

I

 * Idle : (Said of a card) Available as a discard; not required for purposes such as guarding the opponents' suit or interfering with their communications.


 * IMP (International Match Points): 1) (Noun) A method of scoring in a team match that compares a result on a board to that obtained at the other table and that converts the difference to IMPs using a table defined by WBF. The IMP scale's effect is to reduce the influence of very large differences, thus making it less likely that the outcome of an entire match will depend on one board only.
 * 2) (Verb) To perform the IMP score conversion.


 * Impropriety : A breach of ethical conduct or etiquette; an action that violates the Proprieties.


 * IMP s: The form of duplicate bridge that uses IMPs as a scoring method, as distinct from a game scored at matchpoints.


 * In back of : A card or holding that is to the left of, or behind, or over another. To say that the SS undefinedA is in back of the SS undefinedK is to say that the ace is to the left of the king, or behind it, or over it; so, the SS undefinedA is in a position to directly capture the SS undefinedK.


 * Individual : A form of duplicate bridge, scored at matchpoints, in which each player is paired with a different partner on each round.


 * Informatory double : A double that is intended to convey information rather than to exact a penalty from the opponents. Such doubles include the takeout double, the negative double, the support double, the responsive double and the lead directing double, although the latter is intended to convey information and to penalize.


 * In front of : A card or holding that is to the right of or under another. To say that the SS undefinedA is in front of the SS undefinedK is to say that the ace is to the right of the king, or under it, and normally cannot capture the SS undefinedK if it is guarded.


 * Insufficient bid : A bid that is not higher than the immediately preceding bid, and therefore illegal.


 * Insult : The bonus for making a doubled or redoubled contract is sometimes referred to as the "insult" or as being "for the insult".


 * Insurance bid : A bid, usually a sacrifice bid, intended to keep the opponents from playing their (presumably optimum) contract. The bidder hopes that insurance premium – the penalty due to the sacrifice bid – will be less than the damage from allowing the opponents to make their contract.


 * Interference : A call, such as an overcall or an initial preempt, that is intended to make it more difficult for the opponents to bid to their best contract.


 * Intermediate : 1) Nines, eights and sevens are sometimes termed "intermediate cards." See body.
 * 2) A jump overcall that by agreement may be made with a hand of opening bid strength and a long suit is termed an "intermediate jump overcall."
 * 3) An opening two-bid that by agreement may be made with values just short of those required for a game-forcing opening bid is termed an "intermediate two-bid."


 * Inverted minors: A treatment that uses the single raise of a minor suit as strong, and a double raise as preemptive.


 * Invitation : A bid which invites the partner to bid on to game or slam if he has extra values. It is a non-forcing bid by definition. Compare semi-forcing bid.


 * IPBM: International Popular Bridge Monthly. A British bridge magazine.


 * Iron Duke, Not through the: A hackneyed phrase that describes the play of a high card by a player whose high card holding is led through; or, that player's statement.


 * Irregularity : A breach of procedure, as described in the Laws and Proprieties, in bidding or play. If one is available, a director should be called to the table to make a ruling.


 * Isolate : (Said of a menace card) To isolate a menace in squeeze play is to arrange that only one opponent can guard one of declarer's threat suits. The play is conceptually similar to transferring a control.

J

 * Jacoby transfers: Responses to opening bids of 1NT or 2NT that show the next higher suit and that request opener to bid that suit. Players who use Jacoby transfers usually agree that after an opening 1NT, 2 is a transfer to hearts, and 2HS undefined is a transfer to spades; similarly, 3 and 3HS undefined over an opening 2NT. They retain 2 as Stayman and reserve 2SS undefined for some other purpose. Opener simply completes the transfer with a typical NT opening bid. With an unusually good hand for partner's suit, opener either completes the transfer with a jump bid or bids some other suit, deferring the acceptance (often called a super-acceptance). These transfers were first described in a series of articles by Ollie Willner in Bridge Tidningen in the early 1950s, and were popularized for English speakers in an 1956 Bridge World article by Oswald Jacoby.


 * Jacoby 2NT : By agreement, a forcing raise of a major suit opening bid, used in conjunction with limit jump raises. Opener is requested to rebid in a suit where he holds a singleton so that responder can better evaluate the fit.


 * Jam the bidding : (Slang) To preempt.


 * Jettison : The discard of an honor, often by a defender, and usually to unblock a suit.


 * Josephine : An alternative term, popular in Europe, for the grand slam force. The convention was developed by Ely Culbertson, and popularized in a late 1930s Bridge World article by Josephine Culbertson.


 * Journalist leads: Opening lead convention, mainly against notrump contracts, designed to show both what the leader has, and to request specific partner actions in return.


 * Jump bid : A bid made at a level higher than the lowest level at which that suit could be legally bid.


 * Jump overcall : An overcall made at higher than the minimally legal level: for example, 1HS undefined - (2SS undefined). Originally treated as strong bids, it has become standard to treat jump overcalls as weak, preemptive bids.


 * Jump preference : A preference to partner's first-bid suit, made at a level higher than the minimally legal level. In the following sequence, 3HS undefined is a jump preference: 1HS undefined - 1SS undefined; 2 - 3HS undefined. For many years, the jump preference was treated as invitational except in support of opener's minor, when it was treated as forcing. As of 2001, however, most experts treat all three-level jump preferences as invitational following opener's one-level new suit rebid: e.g., 1 - 1; 1SS undefined - 3


 * Jump raise : A raise of partner's suit one level higher than the minimum legal raise. For example, 1HS undefined - 3HS undefined or 1 - 1HS undefined; 3HS undefined


 * Jump rebid : A rebid of one's original suit, one level higher than necessary, usually showing a six-card suit: for example, 1 - 1HS undefined; 3. The range of strength shown by a jump rebid is a matter of partnership agreement: some treat it as a one-round force, others (particularly if playing Kaplan-Sheinwold) play it as only a little weaker than a game-forcing opening bid.


 * Jump shift: A jump bid of a new suit.
 * 1) As a rebid by opener (e.g. 1HS undefined – 1SS undefined; 3) or responder (e.g. 1HS undefined – 1SS undefined; 1NT – 3), it indicates extra strength
 * 2) As direct response (e.g. 1HS undefined – 2SS undefined): usually, a very strong hand. However, another treatment (weak jump-shifts, requiring prior partnership agreement) uses the bid to show a weak hand and a long suit.

K

 * Kaplan-Sheinwold (K-S): A bidding system that uses five card majors and the weak notrump.


 * Key-card Blackwood: An ace asking convention that counts the king of the agreed trump suit as an ace.


 *  Knockout : A type of team-of-four tournament in which the winning teams from each round advance to the next. The losing team is removed from play (but see repechage). In a double knockout a team is removed from play only after losing two matches.


 * Kibitzer: A spectator.


 * Kickback: An ace asking convention initiated by the first step above four of the agreed trump suit. See Useful space principle.


 * Kiss of death: At pairs, minus 200. A score of minus 200, down two undoubled and vulnerable, or down one doubled and vulnerable, is a likely bottom against a part score by the opponents.

L

 * Last Train: A conventional bid that is one step above the current bid and one step below game in a trump suit. It is a mild slam try and conveys no information about the suit bid. After 1HS undefined - 3HS undefined; 4, 4 is Last Train, invites slam, and does not necessarily show a diamond control.


 * Late play: A board that is played after the remainder of the event has finished, usually because of slow play or an irregularity.


 * Law of Total Tricks: A property of bridge deals which states that the total number of cards held by each side in its best trump suit equals the total number of tricks available to both sides. This is interpreted to mean that a side can safely bid to a level that equals its combined trump length. See Hand evaluation.


 * Laws of contract bridge : A set of definitions, procedures and remedies that defines how contract bridge is played. The Laws include the Proprieties, which discuss the game's customs and etiquette -- often far more important than procedural matters. The Laws apply worldwide. Individual sponsoring organizations, such as the ACBL and the EBL, establish their own regulations for play, which may amplify the Laws but may not conflict with them.


 * Laydown : A contract that can be made on any rational line of play.


 * Lead : 1) The first card played to a trick, which dictates the suit that others must play if able to do so (see follow suit).
 * 2) The hand that is entitled to lead to the next trick is said to be "on lead" or to "have the lead."
 * 3) See opening lead.


 * Lead directing double : A double by the partner of the prospective opening leader that requests the lead of a particular suit. Experienced partnerships usually agree on a set of suit priorities, such as opening leader's bid suit, doubler's bid suit, dummy's first bid suit, or a suit that dummy has just bid conventionally.


 * Lead out of turn : Playing a card when it was another player's turn to lead. Subject to penalty.


 * Lead through strength : A maxim that advises a defender to lead a suit in which LHO has high card strength, forcing declarer to play high or low before third hand plays. The corollary is that a defender is advised to lead up to weakness in the fourth hand.


 * Leap : To make a jump bid.


 * Leave in : To pass, often used of passing partner's double.


 * lebensohl (sic): Responder's bid of 2NT as a puppet to 3 in preparation for a sign-off. Normally used after an overcall of partner's 1NT opening, or after a double of partner's weak two bid.


 * Leg : (Slang) game. Normally used in reference to rubber bridge. "A leg up" means being vulnerable vs. non-vulnerable opponents. "Cut off their leg" means becoming vulnerable vs. opponents who are already vulnerable.


 * Length : The number of cards held in a suit.


 * Level : 1) The number of tricks that (when added to the book of six tricks) a bid or contract states will be taken. For example, a bid at the four level contracts to take (6 + 4) = 10 tricks.
 * 2) The property of a contract that states whether it is at the part-score, game or slam level.


 * LHO :Left-hand opponent


 * Light : (Adv.) To enter the auction with relatively low values (for example, to "open light" or "overcall light"). To do so can be either a matter of tactics or of general style.


 * Lightner double: A penalty double, usually of a slam contract, that requests partner to choose an unusual suit for the opening lead. This criterion tends to regard as typical (and thus to exclude) a trump lead, the lead of defenders' bid suit, and the lead of an unbid suit.


 * Limit : In the bidding, to define a hand's strength with some degree of precision.


 * Limit jump raise : An invitational jump raise of a major suit, such as 1HS undefined - 3HS undefined. Limit jump raises usually show four-card support for partner's major suit and around 11 HCP or the distributional equivalent.


 * Line : 1) (with "the"): A line on a bridge scorepad that separates points for tricks that count toward game (see Below the line) from those that do not (see Above the line).
 * 2) On a given hand, the play strategy that is adopted by declarer or by the defenders.
 * 3) Bidding: See Up the line and Down the line.


 * Lock : 1) (Noun) A contract that is certain to succeed.
 * 2) (Verb) To force a particular hand onto lead such that it cannot relinquish the lead unscathed.


 * LOL: (Pronounced El-Oh-El) Abbreviation of Little Old Lady. Facetious depiction of an apparently weak player.


 * Long cards : Cards of the same suit, remaining in one hand, after all the other cards in that suit have been played from the other hands.


 * Long hand : In a partnership, the hand with the longer trumps.


 * Long suit : 1) In a hand, the suit with the greatest number of cards. Seldom used of a suit with fewer than five cards.
 * 2) Any suit of unusual length.


 * Loser : A card which apparently cannot take a trick.


 * Loser-on-loser : A card play tactic that attempts to create an advantage by playing two losers, often of different suits, on the same trick. Loser-on-loser play has many applications, including the creation of a ruffing position for declarer, the avoidance of overruffs by the defense, and interference with the opponents' communications.


 * Losing trick count: A method of hand evaluation based on counting losers.


 * Love : No score.


 * Low : (Adjective) A card that is not expected to take a trick.


 * Low-high signal : On defense, to play a higher card, having already played a lower one, so as to convey information to partner. Compare with echo.

M

 * MacGuffin: A defensive card that, if retained, is a liability on one line of play, but that, if played, will be missed on another line of play.


 * Major penalty card : A card that is exposed by a defender prematurely and through intentional play; or, an honor card that is exposed prematurely even if accidentally. A major penalty card remains face up on the table to be played at the first legal opportunity, including as a discard. Compare with minor penalty card.


 * Major suit: The heart suit and the spade suit are major suit s. Declarer scores 30 points for each trick taken in an undoubled contract with a major suit as trump. Because game requires at least 100 points for tricks bid and made, both 4HS undefined and 4SS undefined (or 2HS undefined doubled and 2SS undefined doubled) constitute game contracts. Compare with minor suits.


 * Major tenace : The highest and the third highest remaining cards in a suit, held in the same hand. For example, the SS undefinedAQ before spades have been played. Tenaces define the structure of finesses. See minor tenace.


 * Make : (Verb) To take as many tricks as a contract calls for.


 * Mama-papa: (Adjective) An unsophisticated game, approach to bidding, or line of play.


 * Marked : To be known to hold a particular card: "He was marked with the HS undefinedQ."

 * Master : The highest card of a suit that is yet to be played.


 * Masterpoints : Units awarded for successful performance in a bridge tournament.


 * Match : A series of hands played by two teams in knockout events. One pair from each team sits North-South at one table and the other pair sits East-West at the other table.


 *  Matchpoints : A type of scoring in duplicate bridge. A pair's score on a given board is one matchpoint for every pair they outscored and one-half matchpoint for every pair they tied. (Outside the US these awards are often doubled, so as to avoid the award of fractional matchpoints.) See comparative scoring.


 * Matrix : The layout of the cards that play pivotal roles in certain endplays, most typically squeezes.


 * Maxims of bridge: A brief expression of a general principle - most have some validity but none are true in all circumstances.


 * Maximal overcall double : By prior agreement, a game-invitational double of an overcall that leaves no room for a bid, when a bid would invite game. For example, after 1SS undefined - (2HS undefined) - 2SS undefined - (3HS undefined) there is no room below 3SS undefined for a game invitation (and a bid of 3SS undefined itself would be taken as merely competitive), so a double is used as a game invitation.


 * McKenney: See Suit preference signal.


 * Menace : A card that requires an opponent to retain a higher card in the same suit, as a guard. The term is typically used of squeeze play.


 * Merrimac coup: The lead of an unsupported high card to force an opponent to use an entry before it can be used effectively. Named for a ship sunk during the Spanish-American War, to block the entrance to a harbor. Sometimes confused with, and spelled as, the Merrimack, the American Civil War ship that fought the Monitor. See Deschapelles coup.


 * Michaels cue bid: By prior agreement, an immediate cue bid of an opening bid, such as 1 - (2), for two-suited takeout. The cue bid of a minor suit shows length in both major suits. The cue bid of a major suit shows length in the other major suit and in an unspecified minor suit.


 * Minor penalty card : A card below the rank of an honor card that is exposed by a defender prematurely but accidentally, via mishap. A minor penalty card remains face up on the table until played. The minor penalty card must be played before any other card below honor rank in the same suit; however, an honor in the same suit may be played before the minor penalty card is played. Compare with major penalty card.


 * Minor suit: The club suit and the diamond suit are minor suit s. Declarer scores 20 points for each trick taken in an undoubled contract with a minor suit as trump. Because game requires at least 100 points for tricks bid and made, both 5 and 5 (or 3 doubled and 3 doubled) constitute game contracts. Compare with major suits.


 * Minor tenace : The second-highest and the fourth-highest (or lower) remaining cards in a suit, held in the same hand. For example, the SS undefinedKJ before spades have been played. See major tenace.


 * Mirror : Identical hand distributions: "North and South had mirror distributions."


 * Misbid : A bid that fails to describe the hand properly. Often a misdescription of a hand's shape, as distinct from an overbid or underbid.


 * Misfit : Two partnership hands, neither of which can support the other's long suit. For example, a red Two-suiter opposite a black Two-suiter constitutes a misfit.


 * Mitchell movement : A tournament movement in which, after each round, the pairs sitting in one direction remain stationary, the pairs sitting in the other direction move to the next higher numbered table, and the boards are moved to the next lower numbered table. The effect is to create two events, a "North-South" contest and an "East-West" contest, with a different pair winning each.


 * Mixed : 1) Describing a pairs event in which each pair consists of a male and a female player.
 * 2) A mixed raise is, by agreement, a jump cue bid of opener's suit in support of partner's overcall. It tends to show four card support for partner's suit and the strength of a good single raise. In 1 - (1HS undefined) - 1SS undefined - (3), 3 is a mixed raise.


 * Morton's fork coup: A play that forces the defense to choose between taking a high card that will establish extra winners for declarer, and ducking the trick, after which the high card cannot be cashed.


 * Movement : In a tournament, a progression of players and boards from table to table that enables the desired comparisons among the participants.


 * Moysian fit : A 4-3 trump fit. Named after Alphonse "Sonny" Moyse Jr., long-time editor of The Bridge World, who wrote and published a variety of articles that promoted the virtues of such fits, and bidding styles designed to locate them.


 * Multi : An ambiguous opening bid of 2 that promises one of several different types of hand.

N

 * Natural : A call which indicates willingness to play the contract named: a suit bid suggesting length or strength in that suit, a no trump bid that suggests a balanced hand, a double that suggests the ability to defeat the contract, or a pass that suggests weakness. Compare with Artificial.

 * Negative response : A bid that shows insufficient values for a stronger response. For example, a 2 response to a forcing 2 opening bid is often negative, as is a 1 response to a Precision 1.


 * Negatgive slam double : In a competitive auction, the double of a voluntarily bid slam to show no defensive tricks, and therefore to suggest a sacrifice.


 * New minor forcing : By agreement, after 1m - 1M; 1NT, a bid of two of the unbid minor as artificial and forcing, often requesting three card support for responder's bid major or four cards in the unbid major. Sometimes called PLOB.


 * New suit : A suit that has not yet been bid.


 * No bid : An alternative to "pass". Used in the United Kingdom, where "pass" might be mis-heard as "hearts." Regarded as improper in the US.


 * Non-forcing bid : A bid which partner may pass. See also forcing bid, invitation, sign-off.


 * Non-vulnerable : The state of vulnerability in which both bonuses and penalties are smaller. Therefore, less is at stake for a non-vulnerable pair investigating game or slam, or that is contesting the part score, than for a vulnerable pair. Also, "not vulnerable."


 * None vulnerable : In rubber bridge, the state of the score in which neither pair has made a game. In duplicate bridge, the vulnerability condition under which neither pair is designated as vulnerable for the board in play. Also, "neither side vulnerable."


 * North-South : One of the partnerships designated on duplicate boards.


 * Notrump : A contract, or a bid that names a contract, to be played without a trump suit. In the bidding, notrump is the highest ranking strain.


 * Notrump distribution : balanced distribution.

O

 * Obligatory : 1) Of a finesse: A duck, made in the hope that a high card will fall. For example, declarer holds HS undefinedK432 opposite dummy's HS undefinedQ765. The HS undefined2 is led to the HS undefinedQ, which wins. Declarer now leads dummy's HS undefined5 and RHO follows with the HS undefinedJ. Declarer ducks, hoping that LHO must now play the HS undefinedA. The play is obligatory because given the first heart trick, no other play can yield three tricks.
 * 2) Of a falsecard: A falsecard that, like an obligatory finesse, cannot lose and might gain. An example is the play of the card that one is known to hold (for example, the play of a queen after it has been successfully finessed).


 * Odd : Specifying a level. To make 4HS undefined is to make four-odd.


 * Odd-even discards : A defensive carding scheme under which the play of an odd-numbered card is encouraging and that of an even-numbered card is discouraging. The rank of the card may be used to show.

 * Off the top : Said of some number of tricks that can be lost or won without gaining or losing the lead. "There were eleven tricks off the top in spades," to mean that declarer could take eleven tricks without interruption; or, "We're down off the top," to mean that the defenders can take at least four immediate tricks against 4HS undefined.


 * Offside : Unfavorably located, from the point of view of the player taking a finesse. If East holds the K and North the AQ, from South's point of view the K is offside. Cf..

 * Opening leader : The declarer's LHO, who always makes the opening lead.


 * Opponent : A member of the other partnership or team.


 * Optimum contract: In unopposed bidding, that contract which cannot be improved upon by further bidding, nor could have been improved upon by taking a different line in earlier bidding, with regard to maximum points and least risk of failure.

 * 2) To play, from third hand, a lower card than the one led to the trick. If declarer leads the HS undefinedJ, LHO plays a small heart, and declarer plays the HS undefined2 from dummy's HS undefinedAQ2, declarer has passed the HS undefinedJ.


 * Pass and pull : To make a forcing pass and on the next round remove partner's double by bidding.


 * Passed hand : A player who passed instead of opening the bidding. The inference is that a passed hand does not hold the values required to open the bidding (unless playing a strong pass bidding system).


 * Passed out : A hand is passed out if the bidding begins with four consecutive passes. After a hand has been passed out, the players immediately proceed to the next hand.


 * Passive defense : An approach to defending a hand that emphasizes waiting for tricks that declarer must eventually lose, getting off lead safely, and avoiding plays that will set up tricks for declarer. Often indicated when neither declarer nor dummy has a running side suit or when the declaring side may have over-reached in the bidding. Contrast with Active.


 * Pass-or-correct : A bid made in response to partner's ambiguous call. For example, South opens with 1SS undefined and West bids 2SS undefined, by prior agreement showing hearts and a minor. North passes and East bids 3, expecting West to pass if he holds clubs and to correct to diamonds otherwise.


 * Pass out : 1) To make the third of three consecutive passes following a bid, double or redouble.

 * Pattern : See distribution.


 * Pearson points : High card points plus number of spades held. See Hand evaluation.

 * 2) A remedy assigned by a director to redress damage done by an infraction. The penalty for a minor, procedural infraction might be some number of tricks, matchpoints or IMPs, or disallowing a particular bid or play. A more serious violation of the game's Proprieties may be imposed by barring the offender from an event, a portion of an event, or from organized bridge.
