Preflop: textbook call out of the loose games section in HPFAP.

Flop: I'd have called and seen what the turn brang. (I know, brought, but I like brang.) Since the guy knows you like to make plays and he bet into the field, a 3-bet is likely and unlikely to lose many, if any, of the limpers. I can even see an argument for folding as you're unlikely to have a winning hand by the river. Were you raising not fearing a 3-bet in the hope that his 3-bet might clear out some of the others?

Turn: the pot is pretty big now so putting in the extra bet to see if he'll lay something down has merit. He might be thinking you would have raised pre-flop from the button with a hand you were going to play with an ace in it. Usually, though, when a guy bets the turn when an Ace comes it's a sign that he has something with which he wants you to raise. Plus he knows you like to make plays at the pot. I smell trouble.

Hope I'm wrong.
