I would think he'd be folding whiffed overs to a shove, but with his AF there's a decent shot he'll bluff them again on the turn. The only hand that calls a shove that you beat is JJ (which is questionable given preflop, but certainly not out of the realm of possibility for him), and that will probably stack off on the turn anyway barring an A or K hitting (and if one does, you shouldn't be looking to get it in anyway).
