I bet at least $5 on the flop too. If he has one of these big draws I think it has to be specifically AhJh or Jh8h. No other draws are big enough for this sort of play. Also, Jh8h would have been folded preflop, so you can confidently rule that hand out.

Since it's so rare that your opponent has exactly AhJh, you are probably facing a made hand like QQ/99/JT--people love to see flops with these three hands, so I think they are worth worrying about. There is an outside chance you are facing KK/KQ, though KK probably would have 3-bet preflop (and would not play the flop so strongly) and KQ probably would have folded preflop.

I would fold.
