Opener is an unkown and i flatted because of stack size to get the main villain in the pot. Villain is a megafish and is running at 47/5. Fold to cbet of 10% over a pretty big sample. I've seen him call down with the weirdest crap

Because he's so passive, is river a fold getting 3.5:1? It really feels like a fold but in the middle of the sesh I made the questionable call
