Why not just let go of the hand after the turn?$1/2 limit isn't going to scare anyone out of the hand so chances are he's got an Ace-rag anyways in Low limit so why put dead money into the pot like that?I might have taken a free card at the flop since if he is any good he will know that you wouldn't play 9/2 to hit an orphaned flop like that anyways and that you are just trying to steal. It may have made him think about betting out at that Ace on the turn or you may have gotten him to fold with a re-raise on the turn had you checked the flop. Again the limit is pretty low to try shake anyone
