I raise the river.

This is why. What hands can he 3-bet preflop and raise you on that flop with? AA, QQ, JJ, and 99. What about AKs and AQs? AQoff suite is possible but he don't have AKs in spades that for sure and neither is AQs. Will he cold call with AQoff? Probably yes with his stats. Which leaves us at AA, QQ, JJ and 99. He is checking the turn even though you guys only cold called his raise on the flop. This is making me go hmm,,, if he had QQ he would bet, probably same with 99 but if he had AA with the club he would bet too. I am pretty sure he don't have the A of clubs or he think his J of clubs is good enough to raise with.

I raise and cap being a happy man.
