I almost always bet the turn here when the ace hits. Bad players like the BB always assume the stealer has an ace in his hand so when you continue betting after it hits the BB will fold a lot of these turns. So the turn should be a bet/fold (fold if c/r'ed which seems very unlikely from this player) and check behind the river. If he donks the river then you just have to fold but I think bet turn check behind river is your best play.
