This isn't a great hand to show AK losing. Even if you had A2 you shouldn't be folding there. Odds are that your opponent missed the flop just as you did. The only hands you are concerned about are pocket pairs.

I love the posts about dwan being a donk. He's far from it, he has a great understanding of the game. His style is based on a deep understanding of odds and player tendencies. He's basically preying on all the poker info that tells you to play tight aggressive.
