I dont think he is going to be fucking around too much in this pot and with the turn check through he most likely has a mid PP, a completely whiffed hand or a hand like JJ that you are behind. If we push this river it is pretty doubtful that he is going to be folding anything we beat and I doubt he is calling with something we beat. The one thing Id be worried about, since we are oop, is him bluff pushing the river but all we could do is push to prevent that and I dont really think thats much of an option. I think this is played fine without a better read [i.e. that he is prone to bluffing in 3bet pots beyond a cbet, etc.].
