I assume you're asking because of the way the freerolls have been. Anyway I know I have to shove when the blinds will eat me alive and I am nowhere near the bubble. As far as an exact number I'm not good at math so I would like to no the answer too. It used to be I could make it to the final table by building a nice sized stack by playing a few good hands and picking my spots patiently. That's no longer the case so I need advice on this subject too.
