Fold preflop.
AJ is a tricky hand to play OOP in a raised pot.

Action is messed up on the flop.

About 50% of the time here I'll make a half pot-sized bet here and the other 50% of the time I'll check/fold. The worse the player is, the more likely I am to bet here. Since you don't know much about him, I'd probably go the check/fold route. Also, calling raises from the SB with a hand like AJo is usually a leak since you'll lose a bunch of money to AQ and AK and not make much when an A falls against lower PPs.
