The problem with tournaments is a multitude of vary factors. What stage of the tournament are you in and whats your play style and stack size?
More often than not, to win a tournament you will have to win a chunk of your chips from multiple all-in situations where you have at best 55% equity.
Just off the top of my head as an example, let's say you get into a pot early on and you flop a nut flush draw and figure the other guy has you beat otherwise. So you've got 35% equity. If he jams, how good of pot odds would you need to call? I'd probably fold even with 30% pot odds, but call with 25%. Just from thinking about it quickly, I feel like I would pass up a drawing spot like this unless I was getting 8-10% better pot odds than my equity. Maybe that's too tight, what do you think?
So lets say -You have AsKs preflop and open, villain 3bets, you 4bet, villain calls.
Flop comes 10s 2s 6d you check, he jams and its about pot.
I would say you have to call. Why? Well in general because of concepts i tried to articulate in
this thread,(i think this ties into the term "realizing equity") but also,
A) It is early in the tournament, you might be able to re-enter and you've essentially crippled yourself if you fold.
B) This kind of play ties into high risk high reward/get a monster stack early and make deep runs or bust early.
I think lots of people advocate lots of different strategies. However tournament poker generally ignores the direct mathematical answers of pot odds. The more important questions are, how much of my stack am i going to have to risk, how much bigger can I grow my stack, what are the ICM implications of my play.
What I'm starting to believe is that you cant go into a tournament and play to a defined game plan. (I'm going to play rock tight poker early, loosen up and steal/re steal middle, and go TAG late). There is such a high amount of variance in tournament poker, I'm inclined to believe there isn't a single GTO strategy. Strategies that work depend on the risk/reward path you are trying to take combined with the play style of your opponents.
