Final Pot: t1560
He turns over A9

With a stack just over 4M (605/150 = 4.03) I would have pushed pf w/A-9o (it beats over 1/2 of other possible Ax).
With A-6o and 2nd chip leader I can see where you could afford it (if UTG & MP1 don't mess it up for ya) but I've stopped being the table cop and my stack is healthier for it as well as better finishes at the final table. Once not that long ago I would have called but not anymore - just got to be too expensive.

You got the first part of it right when you checked . . . . next time fininsh off the play with a FOLD.

Mixed bag here. First off, I don't like the odds, 2-1 explicit with your whole stack at risk implicit, worst implied odds are that you donk off 500 chips when one of the EP players CR's.

If you were the CO (for whatever reason you played A6o there), and the short stack was the button, and the action was the same: everybody checks, He pushes, everybody folds, then I think its an OK call, since he could have any two in order to steal the pot. But in the way this falls, there are two major hurdles: The other guys left to act behind you, and He bet into 1 player who has yet to act. This tells me hes got a hand strong enough to handle a call if it comes, or at least hes willing to risk a call. Given his limp, I put him on A2-A9, maybe <88 but I think those push PF. Of the Aces, A2, A7, A8 and A9 beat you, while you beat A3 A4 A5. Since the majority of the hands that he's probably pushing with beat you, you should fold this given the odds.

But, if we assume 70% aces and 30% pairs, using the Hand evaluator I made, We only have 42.3% equity in the hand. Even if we use the unweighted equity (51%), the chances of getting smacked from behind kills this break even situatiion.
