I labored with this one too. I had something wrote out then hesitated cause I didn't know what to do with the river. Villain's line is very strange. Some type of read would really help here. His line pre flop is very strong, esp since he seems to be very passive post flop. I don't 4bet pre flop cause IME a limp/raise pre flop is usually a monster, so I'm proceeding very cautiously after just calling the 3bet.

I would raise the flop more, maybe his bet could have been some type of block bet with KK,QQ or something.

He donks the turn so weak you have to at least call, odds are really good.

The river is tough, his bet is actually a decent size, and his line has been pretty strong if you can disregard his previous bet sizing. This could just be a very passive Villain trying to induce someone to do the betting for him the whole time. His line is pretty confusing though. I guess I'd fold the river, but I sure wouldn't like it.
