He wouldn't re-raise, though, he'd just call your raise, so you're left none the wiser. Except for the knowledge that whatever you do, he's happy to let you do it, which should be a worry.

His $8 call on the turn would have worried me most here. Why isn't he put off? If he's a regular fish, as you seem to imply, then an $8 raise is enormous. Which means either he thinks you have AA (prob not, as you haven't bet like you had it) or JJ (maybe) or he thinks he's got the nuts - either way, he's happy to risk it.
