Well, I would certainly be afraid of KK here.

You have the Ah so a flush draw is less likely but he could have KhQh if he's loose enough to call $100 reraise with it.

How deep are each of you?

EDIT -
**** nevermind I just reread the post and realized that button cold-called the CO's raise making it less likely (but still possible) he has KK. ****

I would need reads here - is button tricky enough to smoothcall a pf raise with KK?

I think KhXh or AK are more likely.

If he's weak-tight he could have a baby set and be afraid of KK himself.
