I am sorry but direct me where in SS2 it says to flat call against a aggressive SB trying to steal your BB with QQ?
We arent talking about unnecessary risk here, we are talking about getting money in the pot when you crush the range. If you are going to wait for the nuts everytime you will not fare well in these tournys, you have to put pressure on people when you crush their range.
True early in the tourny its not as important and you can play more cautiously, that said this isnt a time, he is raising with almost any two cards here, make him pay if he wants to see the flop.
Is this a $150 freeroll? I think you gotta call this, getting into the money shouldnt be your goal, FT or winning should be. Does he really push here with a made flush? I doubt it.
As for your million dollar question, of course I play the same way(or would really try and hope I do). If you are not playing optimally then dont play you are wasting your money. I also dont understand your cash game comparison? Going all in early in these tournys is from idiots who either want to double up or go home with any two decent cards, cash games are quite the opposite.
Knowing there are a bunch of idiots who are hoping for a coin flip to double up early in a tourny is even more reason to raise with QQ and hope to get all in.
