25NL 6m - AQo TPGK raised by unknown

I never fold this against an unknown. You raised with AQ and hit an A, so I don't see why you would fold. If you are going to fold now, you may as well have played the same way with 72.

I call flop raise, check/call nearly all turns, and then check/re-evaluate river, depending on what he does and board texture.

What value hands do you think he plays like this?
