Also.. unless they are reraising from the blinds, they will have position on you. If you do decide to call a reraise, you are going to be paying off AA anyway if there is no A on the flop. If they don't have AA (the FAR more likely scenario), then you just devalued KK incredibly.. if they hit the flop (A, 2p, set, whatever), then you are paying them off big, with the exception of the pair of aces. Even then you are still losing money against a hand that likely wouldn't have been in the hand if you rereraised. (Except maybe AK). If they don't hit, the best you can hope for is that they put you on a cont. bet and raise you with position.

Anyway, the point: you should be rushing to put your money in with KK preflop. If you start folding KK everytime you think you are up against AA, I gaurantee that is -EV.
