I'm not really a fan of betting more than the pot, or making huge all-in plays - however, I think I should have made that play here. I recognized the scenario / what my opponent had - I should have made a bigger bet on the river, or just re-raised all-in on the turn. I took down a nice pot, but in retrospect, I could have taken his stack.

I wouldve reraised the turn. He would put you on 2 pair (probably 86 or K8) and I think you wouldve gotten his stack before the hand was over.

I was 90% sure he had 66 or 33 when I was reading the hand with 10% chance he had KK.

This is one of the few situations where you might have been able to get away with a gross over bet on the river and get paid off. I agree with Ice about betting the turn. Since there is no real draw on the board you opponant is raising for value, he is not trying to protect his hand. The only reason for his raise is that he is trying to build a pot and extract more money from you. I'm surprised that he only called your river raise, but with a raise on the turn he has to be more into you on the river, or check either way the pot is bigger and you can get more value out of your river bet.
