Useful aces hypo

[wazz]

You are 300 BBs deep, and are UTG with AA26 no suits. You raise the pot preflop. You have a perfect read on the CO - 'stickstacksin' - in that he will only and always raise again whatever his stack size with any AAxx and stack off on any flop with it. You also have a perfect read on button - his screenname is in fact 'got2cdaflop' - will rarely fold preflop, but will play flawless postflop poker, he is in fact your nemesis and has never misread you.

CO potraises you, and the button coldcalls. Your play?

Part 2: same situation, but you get to choose what aces you want. Assuming you would fold some aces, which would they be? Are there any aces you would just call preflop? How good do your aces need to be to stick it in?
