Just thought I'd add this to the mix as it seems fairly relevent: -

"If you play a little from column A (limit) and a little from columb B (Tournies or NL) a good rule of thumb for your bankroll size is never risk more than 5-10% of it on any given day.

The numbers might be a little off here or there but the idea is: If you're never risking much of your bankroll from day to day, you allow yourself to play your game risk-free. Losing money won't drive you to suicide *cough* And your back should never be against the wall. "
