I have been getting into it with this guy, pretty much every time i raise preflop and bet the flop I check the turn and he pots the river. Is calling here just dumb with AQ?

Xaston's method for calling river bluffs:

Pot odds * 5 seconds = how long you're allowed to think before you can come up with a feasible hand for your opponent to play this way, that you can beat.

In this case, you're getting 2:1 pot odds. Therefor, you have 10 seconds to come up with a hand that makes sense for him to play this way, that you beat.

I don't know about you, but it's taking me over 10 seconds to come up with one, and as such I think this is a fold.

Im guessing you don't have the , if so folding here is fine.

This kind of player is easily explotable, on dry boards check the turn with your top pair hands and he will keep bluffing chips your way.
