This brings me to a couple of points/ questions:
1. A little bit more of a raise preflop might have been what the doc ordered, not that QQ is going to lay down preflop but AKo is a better opponent in a heads up type atmosphere.
2. Would just checking preflop be a bad move here? A raise preflop usually means you have at least one Ace in your hand (typically speaking) and it wont be very costly if you miss the flop. Since you raised preflop it gave Mr. QQ the initive to push on the flop since there was actually money in the pot to be won. I also feel a check here would open some doors to see a cheap turn and river, yes there where many limpers in the hand but that could also mean that a lot of the cards you need to come are used up. I know these two situations i listed above contradicted eachother but one or the other could have been made. I think if you would have checked preflop this would have accomplished two things, getting a cheap turn and river, and also switching gears. I dont think your play was wrong, just giving you different options to think about. Great fold on the flop!!!
