OK, is checking the turn a mistake here? My thinking was after he c/r flop and now checks turn he has probably given up on the hand or has some marginal hand and he wanted to take it down on the flop. So I decide to check back and give him the opportunity to bluff the river.

It's not the greatest river for me, but it's a pretty good river for villain to bluff at.

Thoughts?
