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.
I went all-in on thirty miles and that river rat caught a runner-runner flush.

Follow the zany antics of our combat surgeons as they cut and stitch their way along the front lines, operating as bombs and bullets burst around them; snatching laughs and love between amputaions and penicillin.
