Another thought about BRM on a small roll
Since this is officially "harp on about bankroll management" month.
I was thinking about this last night. Even if you're prepared to redeposit, I'm going to assume that most people who are depositing small amounts online are doing so with the intention of learning poker (or learning to get better anyway). Now lets look at it in REALLY simplistic terms. Lets say every time you get stacked, thats an opportunity to learn. Well playing 2NL on a $50 roll you then have at least 25 learning opportunities. If you were playing 10NL, you may only get 5. Now sure if you're prepared to keep depositing up to $250 then you get your 25 learning opportunities, but now those learning chances have cost you $250 instead of $50.
So one way to think about it, is setting the price you're paying to learn your lessons.
