I like the way you played the hand. Its hard to put him on a hand with those maniac stats, but there is usually a better spot to stack a player like this.

Raise more pre-flop if you are going to 3-bet - though against maniacs I really don't mind just flat calling. CB bet is meh. I'd often check - and do the same with AA.

Raise more pf. I actually don't mind a flat-call pf against somebody that aggressive, but a 3-bet is fine too.

Flop I like a check. First of all, against a maniac you're going to be checking a lot of hands and letting him hang himself, so you're not giving much away by checking here. Second, maniacs love to raise c-bets on paired boards and your hand can't stand the raise.

As played, you gotta fold the flop.
