Heads Up vs a Maniac with Ace High

[cartman]

Assuming that my opponent is a maniac with the following characteristics:

1) Literally never folds the flop heads up
2) Literally never folds the turn heads up
3) Is virtually guaranteed to raise at some point postflop heads up
4) Bets when checked to 100% of the time on any street
5) Literally shows down every King high or better heads up

My standard operation procedure when I have raised preflop and I am out of position with an unimproved Ace high is to autobet the flop and then check call both the turn and river against this guy. I sure feel like a moron paying off with A2, but folding seems like it would be criminal.

Am I correct here?

Thanks,
Cartman
