I can't tell if you're trying to level, trying to be stupid, or trying to ask a real question, but I'll give you the benefit of the doubt.
The pre flop 4bet was solid based on the description of the player that was in the hand.
You want to get value from your hand, and it looks like you did. Some people here will say things about the sizing, but we got exactly what we wanted, heads up with the maniac with a very strong hand.
On the flop, you should certainly let him ship it blind, and you should never allow him to change his action. If you bet anything at all, it allows him to play his hand based on what happens on the board, and we rather have him betting with less information. When he shoves blind it does not allow him to have the same information that you do. So, check, let him shove blind and play accordingly.
Call on the shove seems reasonable, as you said that he's a maniac, and he could have a wide range of hands here. We have an SPR of 1. And while there is an Ace on the flop, if you think that he's a maniac he can shove with worse. (Obviously, since he did it blind, he can shove with his entire 4bet calling range. Which can be just about anything for a maniac.)
