Look good? Villian was very aggressive. Bet his TT all the way against opposition with two overs on the board. He's been caught firing second barrels a few times already and has been up and down. If he has a flush, he's getting in probably no matter what on the end. If he has air, which I half-suspected, the only way to get more from him is to not 3-bet the turn, check to him and let him bet the river, which I was 90% sure he would do. Thoughts??

EDIT: I forgot to mention, one of the reasons I suspected air on the turn was the minraise. He had made legit raises with made hands before this hand.
