I can't give him credit for the straight here, and I don't see most unknowns checking the flop with an ace. I bet the turn for about 400. As played, call the river. I think it's a steal often enough that you have to call, given the odds.

Also, I agree with StregaChess about the pfr - 6xBB is a bit much - make it 3-4xBB. I think betting the flop is fine, considering you were checked to, but checking behind for pot control is probably also fine.

Question though: If we check the flop, and the turn comes while we're three way, what's our action if BB bets and MP calls? How about if BB checks and MP bets? Assume each bet is about half pot.
