Complimentary Play (poker)
Giving someone action where it is not necessarily warranted.
For example, in a Southern California double blind lowball game,
you have beaten someone in several large pots. Now you have
the blind. He opens for a raise. You have absolutely nothing,
something like four face cards and one small card. Normally
you would not call the bet, but would just throw the hand away.
Instead you take decidedly the worst of it, perhaps drawing
four cards, in order to appear to "give" him back
of the few of the many
dollars you won from him. This is a courtesy play.
