Ace/rag on the button

[Bona]

If you give BB credit for playing OK don't we have to think he is ahead of top pair since he bet into aggrssion on this board? If so what can we draw here that wins? An ace MIGHT buy us a tie. A five may alrady be dead to 2 pair although there is a chance he would have 2 pair w/0 aces. I dont see a turn call. I don't think this wins veryoften from here. IMO it is a fold.
