Villian is a complete unknown.

How could my play here have been improved?

Hypothetically, if he had re-raised me on the flop, would you be willing to go to the felt?

I hate these. You invite a bluff that you can't really call if you check the river. But betting it isn't much fun either. I'm also not sure why you reraise... you'd love this headup but you wouldn't mind 3 to the flop either.

wtf?

sure reraise, you have his range mashed. Id have prob pushed the river i think, i think we'd have heard from KJ or a set by now.
