AQo in EP turn play???

About the worst river card. All the overcard hands (AJ,KQ, KJ,QJ) are now beating us. I don't think a loose opponent can be bluffed out very often in this spot. Also, since our opponent is passive, he is not so likely to try to bluff this river, so if he has a weak A, he might check it down. So I would CHECK/FOLD.
