I think what hand each player has is basically a non issue. If player A is a better player, than player A has the best of it. If player B is a better player, than player B has the best of it.

If I was player B and I KNEW that player A held AA, then I would not call a raise unless I think that player A is stupid enough to donk off all his chips when I hit a set.

However, since I dont acutally know that player A has AA, I feel that (especially in 6 max) I can steal alot of pots from player A, postflop, given that I have more information on his hand that he does mine.
