AA oop against maniac

[norad2]

Game is 6max 25NL

Maniac is playing 68/42 with 100% attempt to steal blinds over 130 hands

Maniac raises to .85 on button
Passive SB calls
I have AA in BB. I know he will call if I pot it or make it slightly larger than pot so I make it $6 looking to take down a small pot rather than play an overpair out of position against a crazy person.

He calls. SB folds.

Worst imagineable flop comes: 9h 10h Qs

Pot is $13

How do you play this hand post flop?

My thoughts - He will raise with any two cards if I check. Any reasonable c-bet nearly commits me to the hand.
