AKs vs maniac

[Cosimo]

To be honest, I'm not very comfortable playing for my whole stack against someone that I can't read. I felt lost. Please, obitwoplustwoey, you're my only hope.

Villain is 30/9/5.0, with 77/56/59% fold, so he's bluffy and/or bets any piece of the flop and generally doesn't get played back at. I've seen him smallbet an ISD on the flop.

1) Should I have reraised preflop? What to? Push?

2) Given the way I played, what's my flop action?
