1) You don't want to 3 bet an utg raiser but you're willing to float on a board that smokes his range compared to yours? He's not folding river often enough imo if that's the question. I also don't 3 bet pre.

2) I c/c he's probably c betting too much and is going to play pretty straightforward on later streets. Is a 16/16 nit really felting worse on this board?
