re: Poker & calling to chop? is it ok?
common sense prevails in those situations.
in this specific one i wouldn't worry about it too much, it comes up pretty infrequently. however we can apply your thoughts above to a bunch of different situations.
obviously if we're sure we are chopping, we're only winning 50% of the blinds, or 50% of whoever might have called preflop. so taking down maybe 1-2 bb's doesnt really seem worth the risk when we can just fold and steal the very next hand with no risk.
in the example above, you include AQ, so we win the pot there a decent amount of the time, but we also have to factor in things like he could possibly have worse than AQ, and the possibilities he could have better. just from a probability standpoint, he is likely to have worse more often than the nuts. (also can't exclude the times he has aq and binks the river).
it comes down to how sure you are on your read, then we need to factor in random times he has the nuts, or doesnt and still outdraws us when we call. so the equation is definitely in their favour.
so unless your sure there are hands that we beat a decent amount, then folding is the best route, because we stay at that same stack size 100% of the time, rather than gaining a few bb's a large % and being eliminated from the tournament a small %.
also, what the buyin means to you has a lot to do here. extreme example, we have AK in the same situation on the bubble of the WSOP
ME, folding here guarantees our stack, and basically guarantees our cashing in the tournament. by calling, we gain very little to our stack, and we bust the tournament 2-5% of the time. if that buyin means a lot to you, then the choice is clear, it has nothing to do with books/strategies or anything, it's about common sense and what cashing in the tournament means to you. now if you are phil ivey in the same spot, who cares, just call because your likely ahead a small fraction and can get more chips.
