I agree with most everything already said except that unless I've got a read that someone will ONLY 3bet with KK, AA then I'm going to look to get it in pre.
The reason behind this is that you want to develop a range of possible hands that your opponent would be holding and QQ is ahead of all but two hands: AA and KK. Granted it's only a slight favorite to AK, but you still want to get your money in when your ahead.
