Villain is 18/12/1.64 over 500 hands, hasnt be 3betting me a ton but I suspect he has done somewhat light IP, 3bet stat of 5% over this small sample. I dont know how pre is I just didnt feel comfortable getting stacks in, flop I suppose I have to peel one, is he betting worse on the river enough?

Pretty tough spot..However I just dont think you are beating too much of his range..The only hand we really beat is AQ. I think he is checking any marginal hand back because of the showdown value he is getting. It also depends what his view of you is, if he thinks you are going to fold out QQ-TT. I would say I try and find a fold here, not too often are you winning this pot. I think we see AK a lot and KK getting tricky trappy on the turn b/c of the board pairing. AA of course also however I think AA is betting the turn. I would say his most likely hand is KK..

if you´ve seen him do anything light pre IP i 4bet the QQ there a fair amount of the time.

river aggression would be interesting and W@SD.
as played i pay him off with his "tricky" turn-check behind.
i like a river-bet for value ~ same size. 88-JJ doesn´t get a cheap showdown and you can fold to a shove.

Bluffing makes no sense for him at all there but he could be value betting JJ/TT so I ain't sure. You misplayed preflop

Against a button repop I definatley repop pre.

River is a tough spot. I think I usually call this. If he has a strong hand on the turn, betting makes it easy to get it in on the riv and he didn't do that so I definately want to see his hand. Plus you don't have to be right all that often here.
