Villain here is a fish, and I am not using the term loosely. He will limp in with any two cards in any position, including 74o which was shown down for 7s up in an earlier hand. He is not exactly passive, though, and will raise good hands both pre and post-flop, but usually overvalues hands, as well.
Effective stack size is 650.
Hero has 7

in UTG+2. Villain is UTG.

(POT: $287)
Villain bets $200. Hero?
I hit one of my draws, but it also improves a set or a cheesy two pair to a boat. I obviously do not spaz here and raise, but can I even call?
