Villain in the hand is playing 52/17 over 100 hands. Played a hand vs him where he flatted a set on A7xtt, and shoved over my turn barrel. Also, he doesnt seem very spazzy.

UTG is a reg playing 18/14 with 62% fold to 3bet.

I flatted pre to keep the fish, I have position and 3betting the UTG open looks too strong for me to profitably stack off vs a 4bet vs this guy.

I shove flop here because the fish could easily be stacking like 88-JJ here and I dont want any scare cards coming off on the turn. Thoughts?

I don't think many fish choose such a sizing with a smallish overpair but I could be wrong

given we are 140bb deep i'd fold

he is likely flatting sets to your bet, his line looks full of ****. I would call his bet then check call the rest of the cards.

He's OOP with the PFR left to act still. PFR is mostly folding here anyways but not sure if he knows that. I think he's less likely to flat sets OOP but obviously still can.
