[BluffTHIS!]

Joe, you are right that stack size, position and the bad sidecards with your AA are important considerations in this hand, but you have not properly interpreted them as to how to play. The 2 shorties are real short, so they should be no consideration at all. Then since you can get almost 70% of your stack in by a reraise versus the LAG who covers you, that is what you should do, followed by betting allin no matter what comes if he doesn't set you in preflop. If he folds to that reraise and 1 of the shorties calls and beats you, you can't lose much.

If the other 2 players had stacks similar to yours and were loose enough to call your reraise with mediocre hands, which means you cannot get it headsup, then that would argue for calling only. But it is still reasonable in those cases to get a little more than 10% of your stack in by calling because of the times you flop a set and can double off of him when your hand will be disguised by not playing it hard preflop.

I have said in the past here that I have occasionally folded AA rag hands with a big stack in an aggro game facing other multiple big stacks, but this is not one of those situations.
