[BluffTHIS!]

The key point you all are missing, is that the particular hand in question, QQ42ss should have been folded to begin with in MP1. It is only worth playing on or 1 off the button. Sure the the flop could have come Q53, but in that case, especially at higher limits when there isn't a crowd seeing the flop, you won't get any action from draws or bottom set anyway. QQ needs a suited ace to play a little card with it or two other nearby straight cards. This is known as having a defense. When you flop a set of queens you want some kind of backup, even if only a gutshot or a higher flush draw. This will give you the outs you need to call a pot size bet by someone who makes a straight on the turn. And if by playing good nearby cards you also make a straight, then you have a freeroll and should jam the pot. I even fold KK with those sidecards in that position, because it is not good position and really can't stand a raise.
