How do you manage your bankroll?

[el_grande]

While I may agree that a 300BB bankroll is not necessary, I disagree with what you say about money managment there.

If you are playing $2/$4 with $100 with the intention of replenishing the money, $100 is not your BR. Some other number is. I believe it is advantageous to commit a BR to poker. Even if you are not doing it for a living, it keeps your other money protected.

I believe you can start playing $.5/$1 with $100 or even $50, but my questions at the start of the thread have to do with moving up or down when you have established a bankroll rather than just starting out.
