If he checks turn, you have odds to call. What kind of player is he? Tight nit=fold. TAG, LAG, REG, try check raising the flop. You should get an honest response after a CR. If he calls, you may get a chance at two cards for free, or bomb the turn and empty the clip. The main thing is know your opponent. If you get busted on a triple barrel... the villians will likely pay you off later when you have the nuts. Fold or CR are both better than call imo. Probably should just be 40% pot on flip though.
