On the flop, you should be reraising again...you have a great hand, but its still vulnerable, and Villain has indicated that he wants to play.

On the turn, I dislike the check...I'd definitely lead here. As played, you should have raised him more ($12 is only pot afterall), and then if he 3 bets, it makes it more sensible to push over the top.

call on the river...if he has TJs (which is the most probable), then that sucks.
