[Riverman]

I hate your flop play. What is the point of min-raising? Presumably to "find out where I'm at" but it doesnt even do that for you because with bad and good alike they react to it the same way. That said, if this guy is as fishy as you describe, AK is not out of the question on the river. Make a read and go with it, although without being there I would be inclined to fold since he bet every street. AA would not be a surprise, but it would all depend on my read.
