There always seems to be a tendancy to consider unknows at the micros to be donks who go wild with any top pair. I think if villain was a complete donk, then hero would have at least some sort of read after ten hands, so I'd be more inclined to believe villain has at least some idea what he's doing, at least until he shows us that he doesn't. We do have a read, that he's not done anything stupid in the ten hands we've seen. Donks can't usually hold out this long without some form of spew.

Having said that, I'd still have AQ+ in his range, to go with the obvious A3 A5 33 55 AA (how is 24 in his range but not 35? I'd say neither are). Never folding this obviously, but I don't expect him to flip over AJ and weaker all that often. When he does, superb, don't forget to make a note.
