In no-limit poker, to bet all of your chips as a sign of total confidence in your hand.
If you have a very good hand, go all-in to win the maximum number of chips or to scare off mediocre hands so they won't catch the cards they need to beat yours. If you have a bad hand, you can bluff by going all-in and hope everyone folds.
A donkey's favorite action in poker. When used by a shark it means the odds are in his favor so fold or possibly that he is willing to gamble for the pot, are you?
