pot committed refers to when you know you have the worst hand, yet need to call because of the odds of hitting your hand by the river. On the river it refers to the amount u need to additionally call a shove for is laying u odds where u think ur hand will be good more often than it needs to be to break even.

just because 3/4, 2/3, or 1/2 of your stack is in the pot doesn't mean you're pot committed. Villain in http://www.flopturnriver.com/phpBB2/...oker-55465.htm
isnt pot committed and the only way to play the hand profitably is if hes not pot committed.
