I don't really think this is a great triple barrel spot. You should be more inclined to triple barrel in a spot where villain's call down range is weak, rather than a spot where their calling range can have a lot of nut'ish type hands that aren't folding.

As played, like other comments suggest, I'd bet more on the turn for sure. River decision is tough to just say. It's probably mostly a feel/timing kind of spot, where you should have a read earlier on in the hand as to how strong or weak he is and go with that.
