Villain is bad, like 50/15, likes to "outplay" people. I have a specific strong read that he overbets bluffs cuz they "look stronger". So I think he had missed diamonds here a lot. Of course you never know he's an FPS-tard he could have a lot of different things.

The question is what's the most +EV move now? Fold, call, or raise? (I think you could make arguments for each)

(ps. I don't usually cold-call this preflop but villain is awful and I have position and we're deep so I'm calling with a lot of hands)
