Agree call. I'd say you have about a 75% chance of being ahead, maybe more. This looks like one of those maniacs that like to bet any little thing (29% PFR!), so he could be betting JJ or even 77...I wouldn't give him much credit, but he definitely could have a set. I'd say you have almost enough reason to reraise the river, hehe, but b/c of the set possibility, juss call.
