Ok I'll take a shot at this as I have pondered the same myself. 1st take a look at the effective stack, ie if you are the big stack then you can't loose your entire stack so who is next biggest. Do you have position on the other big stack(s) and are you confident you can hold your own against them? If not nuttin wrong with moving on. I think it is smart to establish your comfort level and play within about 70-80% of it. I myself don't feel comfortable with 4+BB in front of me cuz I know at anytime my dumbass can slip up and start spewing so I tend to shut it down at about 3.5BB. Now if I've been running hot I'll look for another decent table to fill that spot and to be honest with you the other day I came right back to the same table allthough I don't know how good that is. Nobody bitched although I had to sit out a hand.
