re: Poker & When are you pot committed???
To me, if you know
(or have a very good idea) that you're beaten, you're never pot committed. If you feel you have a chance, or a draw, or some % of a bluff, etc, and especially if we're talking pre-flop when there are 5 cards to come, I would say once 1/2 your stack is in, because if you are put all-in after that you're getting at least 2:1 on your money.
Pot committed should be a function of irresistable odds
, not the feeling that you've wasted chips -- as they say in accounting, that is a sunk cost
so forget about it.
