Is this lay down correct? Should I have played the hand any differently? Is calling with AQ correct?

I was thinking laying down AJ is fine because I often enough have AQ/AK to call with, but actually I would probably get it in with those hands preflop. How can I balance my aces here?

Edit: Do I have enough A8/A4/A2/A3/88/44 here to be balanced even when I never have AK/AQ?

Do you have any kind of read on this guy? I think the laydown is fine but at this stake I think he could be doing this with worse aces (I figure maybe ATo plus a good amount of suited aces, some of which obviously are two-pair here), but he could also have 8's, or the single combo of AA (I don't see 44-22 3betting here). There's also the potential for him to be spewing with like TT-KK here. If I'd seen this Villain **** his pants on an A-high flop with big pocket pairs before, I'd probably be much more likely to call. Without any info, I personally call here but I would love to see an explanation as to why that's obviously bad.

EDIT: Another thought, the fact that you check/call flop and turn make me more inclined to call as well, because I think it's entirely possible that he was attacking your sb minraise with a weak ace and then just decided to fire all three streets. I don't know if AK/AQ go for max value here, for fear of the jam pushing out your exact hand when you might call a smaller river bet.

Villain was 8-tabling, so I assume he knows what he's doing. I don't think he ever bets a worse Ace here.

In that case, he's almost certainly beating you here. His range is definitely way tighter than someone only playing a single table. Kind of a rough hand, I don't know what you could have done differently either. Folding the turn seems bad, and I don't think check-raising the turn is a good play either, really.
