$1 naked AA turn decision

Villain is a weak and aggressive regular. He's running at 36/21/4 over 505 hands. I expect him to be attacking my SB check very aggressively. How would you proceed on this turn card?
On a side note, is the flop an easy stack off if raised or jammed on? All comments are appreciated.

pot/call or like $32/call.

he usually has pair(usually Q)XXX or maybe KK.

What if the positions are reversed preflop and the action goes check-pot-repot on the flop?

Is that an easy fold or do you stack off and not feel too bad about it?
