Ok if you know his cards and your cards how can you play incorrectly? What mistake could you make? If you know he has AA it doesn't matter how he bets, you will be able to calculate the correct play.

If you have him beat, and you want to maximize value, will he raise if you bet? will he bet if you check? will he call a check raise? if you check multiple streets will he bet his whole stack?

If you're beat, but want to draw a cheap card, will he just call if you bet small? will he bet small if you check? could he fold his AA if you make a big bluff? If the flush card hits will he be scared of it and fold?

Clearly you can't play for maximum value unless you know how he'll play his cards in every situation. (you can play optimally in a game-theory sense, assuming that he also plays optimally).
