I will have to agree with traca greatly on one thing: I prefer AK over AA. And I am not the only one to cite this preference, many past champions (including Brunson and Moss) prefer the slickster. Why, you ask, would I want something that loses more often?

Because I will lose less when I do lose, and gain more when I win.

More often than not, if I get dealt AA, I will end up in two situations: I am going to win a small pot, or going to lose a big one. Yes, I will win a lot more small pots than losing big ones, but when I lose a big one, it will cripple me.

However, with AK, the roles are reserved: I am going to win a big pot, or lose a small pot. Again, I recognize I will win less often than with AA, but the pots I win will often be for greater amounts, and I have nothing against folding AK post flop, even if I do hit top pair. FOlding AA, on the other hand, can often be difficult if there is no straight/flush/pairs showing. So, if I am beaten, it will be hard to get away from said hand.

This is not solely Borg's opinion, feel free to pick up a Brunson/Moss book, and read up on it yourself.
