against a player with a short stack the push is correct with A10s if you lost you still had a healthy stack and that is a good hand to play under those conditions
I dont like this play. With ATs you are not even in all that great shape against his pushing range from that position, and even worse you have two big stacks behind you, who can really hurt you, if they wake up with a better ace or a big pocket pair.
This time noone else gave action, and you had him dominated, but that is being results oriented. You just happened to run into, what was probably the dead bottom of his range, and a hand that also matched yours well, because he only had a single free card.
As I said in an earlier post - I think we can easily call this bet if we were in the SB or the BB where we close the action.
