Play the Board

To show down a hand in hold'em when your cards don't make a hand any better than is shown on the board. For instance, if you have 22, and the board is 4-4-9-9-A (no flush possible), then you must "play the board" - the best possible hand you can make doesn't use any of your cards. Note that if you play the board, the best you can do is to split the pot with all remaining players.
