Buy poker
1) As in "buy the pot." To bluff, hoping to "buy"
the pot without being called.
2) As in "buy the button." To bet or raise, hoping
to make players between you and the button fold, thus allowing
you to act last on subsequent betting rounds.
3) In draw poker, receive one or more cards. "What did
you buy on the draw?" means "What card or cards did
you receive?"
4) Purchase chips.
