To cap or not to cap.

[Dankenstein]

Been a while since I've posted a hand. This one is probably a quick answer for you guys, but I'm wondering if the general consensus agrees with my decision on this flop so here goes.

CO is a complete idiot. 88.89/8.33/1.2 over 36 hands
He's played almost every hand since he has sat down and has gone to showdown in about half of them. He's not super aggressive but he's not folding a whole lot either. He sits with a weird number of chips which I suspect to be his whole bankroll.

Not exactly a great player but not a complete idiot either.

I'm not folding here so the question is should I cap it for value or just call and see the turn ?
