Turning Stone 1/2 NL dilemma

[lil_o]

I was at Turning Stone last night when this hand unfolded. Villian (~275) has been playing virtually every hand calling raises with draws, bottom pair, 2nd pair, etc. Villian isn't just a calling station, and has been raising a lot too with everything from top pair to nothing. The villians VPIP would probably be around 85%. Villian recently doubled up when he hit a runner-runner flush against someone who flopped a straight. The best way to classify villian is a total maniac.

Ok, now to the hand. I (~250) was on the button with AKs. EP raiser makes it 10, MP calls, villian calls, I reraise to 40. EP and MP fold, villians calls, heads up. Pot is ~103. Flop comes down A-8-6 rainbow (suits don't matter). Villian leads for 10, I raise to 50, villian reraises to 100.

Hero???
