Talk:play on

Senses unrelated to cricket or other sports?
What sense is it if I say sentences such as "Play on their fears/prejudices/etc." or "Anti-gay marriage PSAs play on the love of children and their futures by parents..." ? --Lo Ximiendo (talk) 16:02, 21 December 2012 (UTC)
 * And another thing, is the sense similar to the sense of exploiting something (in this case, such as someone's weakness?) --Lo Ximiendo (talk) 16:08, 21 December 2012 (UTC)
