NL100 - AQs against limp/minraise preflop

[Kharlog]

The opponent is quite loose postflop (shows down a lot of middle pairs etc) and quite loose on BB (vpip > 40%). He raises about 50% of his hands from button, and calls about 10%, which is a bit tighter than usual. He has never limp/reraised before so I'm not sure what range to put him in. I suggest he either has a monster or is just playing back some weird hands with weird play. Would you raise again or just call?
