i only called pre-flop because i didn't want to risk my large stack
I guess that's exactly what you shouldn't think about.
I read somewhere (can't remember where though, sorry):
There are two types of players, the farmers and the foxes. The farmer wants to finish in the money, the fox wants to win the tournament. The fox will never play scared, he will play his game. The farmer will constantly check how many people there are left to see if he can fold his way to the money...
You will get outdrawn no matter how you play, so you might as well stop thinking about it and start playing your game!
