15-30 flopped second nuts, poorly played

[ANY2CARDZ]

UTG +1 stats are 27/20/3.5 Very aggressive when head up. I was originally going to bet out, assuming he would raise, but for some reason I decided to check riase.
Whats your line on flop and turn. I felt like a pretty big donk after the hand.
Im thinking maybe just let him bet the whole way, and try the check raise on the river?
