Just how pot committed are you?

For those who don't know, being pot committed means that either your opponent has gone all-in for such a small amount that the pot odds demand a call or that your stack is so short that the same thing applies.

When you're in the latter situation, I think pot odds become a less than deciding factor - after all, your tournament life is on the line, and that's worth whatever the tournament buy-in was in real dollars.

Say what?

If he was going to call the pre-flop raise short stacked, why didn't he just move in? I probably would have folded my crappy ace. What was he really hoping to get with his 6-high post-flop? The back-door 78? Even if he thought I was just making a continuation bet, say, with KQo, I still had him down to 6 outs. Yes, there was 1200 in the pot and it cost him 270 to make the call, but it was his last 270, and against the pre-flop raiser. There's no chance at all I had an ace?

Uncalled bet of 330 returned to hero
