Ok as you can see we are both pretty deep, and all he has done is call. Reads on guy is that he's a 44/16/2 over 300 hands. From what I've noticed he's been playing pretty straightforward after the flop, he just likes to see a lot of flops with marginal hands.

I figured if I bet the river for $10-$12 he calls with AJ, JK, JQ... and he'll fold a whiffed KQ or diamond draw, I'm not sure he'll bluff with those or not though, he had bet the river quite a few times before and never been called. I really didn't think he was slowplaying a set or JT, what's the best line to take? Induce bluff? Value bet?

With that board I think he would have raised you with a hand better than yours somewhere during the action...I like your line and it is a must call.
