Villain in this hand is terrible. I had a great read on him, he would always checkraise top pair on the turn, regardless of what the flop looked like.

I was fairly confident that villain was on a flush draw. Betting the turn was obviously wrong, because he's either calling or raising. My question is about the river. I didn't think i'd be able to get him to lay down a jack, but I'd seen him fold some pretty decent hands on the river for 1 bet before. Is this too fancy? Thanks in advance
