Min-Check-Raised on Turn, wtf?

[bogey]

This hand really put me in a weird position. I don't know much about the villain but hes been fairly quiet so far. Thanks for any comments.

2nd question) If you said just call what do you put Villain on, and what do you do on a Club river? If checked to? If bet big into?
