I call down. I think even a fairly passive player is going to raise better aces then Hero has pre-flop, and would bet the flop when checked to if he had any piece of it.

The only hand that makes sense to be behind is A2s. Of course, being behind a slowplayed KT or something isn't out of the question either though.

I think we will see weak aces here often enough to warrant calling. You havn't shown any aggression on the hand, so your bet looks like a steal attempt on the turn. I think even a passive player is raising any ace here.
