AA vs maniac on draw heavy board

[Mark1808]

$5 $10 full ring live. Villan has over 7k and raises 40% of hands and throws his money in the middle on a variety of hands. After two limpers he makes it $50 on the button. If he had a mid to high pair he would make it at least $75. I have AsAh in sb and make it $200, he calls. Flop comes QJ9 2 hearts. I lead for $300 and he makes it $700 more, I have $950 left.

I'm pretty damn sure he has 2 pair, straight or a draw and I am getting about 2 - 1 on a shove. I run through his hand range on poker stove which does not include big pairs (99 up) but includes all kinds of 2 suited (his usually $50 raise range) that make straight, 2 pair or pair with draw and I have him a 57 - 43 favorite. Instinctivly I know I'm beat and I never like to stack off with one pair but with this player, his range and our history I feel a shove is the play. I'm bent over let me have it.
