I realized that I place nearly every time as long as I play almost every hand that is not raised for the first hour of a tournament before the blinds get very high. This has prevailed with catching hands cheap that people do not expect. Also if I do not hit a hand at all, I'm only out about 300-500 chips low my first hour, If not I'm usually close to first. After the first hour I tighten up greatly.

What do you think? Is it ok to play tight the whole game or are there too many missed opportunities when blinds are low to be hand bias?
