5/10 deepish: turned set gets c/red

[Superfluous Man]

Villain in this hand is 37/16. Super passive preflop, on flop and turn, super insano loose from the big blind. Kind of aggro on the river if he sees a river, and I once saw him fire turn/river in position with air, only to get snapped off by top pair. Never seen him c/r turn before. Fold it? Felt it? Call and hope to pair the board? If so, what to do on the river if the board doesn't pair and he bets big?
