I think if he was playing super aggressive, then he wouldn't have checked so much with a big hand. That being said, when a player like that does do a rare "check", it actually makes me nervous that they have a big hand and are slow playing. People try to be tricky like that, bet strong with weak hands and check big hands.

I think it's the classic "nuts or nothing" kinda hand. If he had a big hand, he wouldn't have checked the river, after your turn check. He would've led out since you checked on the turn and has to assume you would check again on the river. But yeah, the raise is either the nuts or nothing, and since he's been playing kinda crazy and bluffing a lot, I would assume he had nothing. If he was playing tighter, I would assume a big, big hand. I guess I'd make a crying call and expect to see ace high more often than a hand that beats yours. =)
