Terp,
Just a little advice on these double up tourneys (DoNs). If you are 6 handed and already sitting pretty, you should probably fold every single hand. I'd need to know the chip counts of all the players to be sure if this is the best strategy in the circumstances of your AK hand. However, if you are sitting at, let's say, 4000 chips or more, you probably don't need to play any more hands. Maybe you'd play AA if you're not already almost certain of winning but that's about it.
