He nearly HAS TO have aces up or better given this betting sequence. He 3-bet 5th before he had a pair on board. I think he was saying right there he can beat queens pretty clearly. I mean, even an idiot can put hero on two queens at least. He is saying he can beat them. The 6th cements aces up and you're clearly drawing. Then you missed on the river. I fold b/c I beat nothing, again w/ the provision that if this person is nuts (ie. raising and reraising on total air w/o regard to anything his opponent could have), by all means pay off. But I didn't get that impression from the OP, just that he is aggressive. I think you can save a river bet here...whether it's $4 or $150.
