Villain seem to be some sort of passive fish, he played 60/7/2 over 250 hands and I had a note of him that he didnt 3b KK...

Flop 3b against his tiny XR seem standard. I can get value from Ax and perhaps even worse made hands that fish might overplay. When he 4 bets flop I got a bit anxious and decided to just call since we're 200bbs deed and becaues i dont rly see this player profile bluffing alot with this line.

Turn villain pots it. I'm not happy about the spot but I don't think I should be folding?

River he jams close to pot size... No idea, folding seem so weak so I called and he had a set of 2s.
