Bet the turn I think and check behind on the river UI. He may still be drawing so you should charge him on it. It also gives you the option of a free showdown or extra money if you hit. This option is far superior to checking behind the turn and trying to pick off a few bluffs on the river.

If he checkraises on the turn you can release fairly confidently knowing that you are drawing to three or less outs probably. I don't see a player of his stats putting in three bets preflop and flop, and then checkraising the turn on some sort of move. If he takes this line, he's playing you with some hand that has you smoked probably.
