Turn scare card

[Absolution]

This guy is aggressive and can spew post-flop (I've seen him raise pre-flop with K5s from early position and I've seen him cap OESDs heads up on the flop), but isn't completely clueless.

I think he will be raising the flop with a lot of draws and junk here, but I really don't know how he will react to a scare card. I think I will end up having to fire 2x here an hope he doesn't have a pair. What if my hand had an A in it?
