rapid chess

Noun

 * 1)  Chess played at a relatively quick time control, with each side getting about 15 minutes to make their moves.

Usage notes

 * The exact boundaries of classical and rapid chess are somewhat ill-defined, with some chess websites considering a game to be "classical" with as little as thirty minutes per side with no increment. This range of time controls is generally referred to as "slow rapid" by the professional chess community.
