If you want to win this hand, I think a check raise all-in is your best bet. If you lead into this maniac, he will literally reraise you with any two cards. He said he hand a big hand preflop, do you really expect him to give it up on the flop when you lead into him? He is going to suspect you have something like TT or 99 and want him to fold which also implies that you will fold to a reraise. I don't know your style but most players won't lead AA or KK into a reraiser preflop on this board and the villain probably knows this.
