What do do in this situation?

[95Aero]

Should I fold this at river, or gamble for an opponent fold?

I think after you bet the turn and were called in two places, you can check-fold your Ace-high on the river. If one opponent folded on the turn to your semi-bluff, then you may be able to follow through with a bet on the river to try to fold your last opponent.

I'm curious what others think about the turn bet.

ADDENDUM: The point of a bet here wouldn't be for value, but to win a pot which you couldn't win by having it checked through. I think the only hand you have a chance to fold that you don't beat is 4x. If you check with the best hand, then it will frequently be checked through anyway and you'll still win the occasional pot.

You should check the river. He's not going to fold any pair that he has made it to the river with nor will he call with a worse hand (you beat a busted draw anyway). Weak players will often give you a free showdown with a better hand.
