I've recently started counting BJ occasionally ( weekends), not professionally but I still got a comfortable edge thanks to good rules. (Where I play the 10$ min 6deck shoe has an initial edge of -0.36) and it seems like nobody cares about spreads!
The only thing I don't get/disagree with is bankroll requirement, I've read things such as "without a bankroll you would be just gambling", and "you need to increase your bankroll to reduce your ROR because your ROR is too high..."
It seems to me that advising counters to first prepare a large bankroll is a huge waste of resources, and saying a lower bankroll increases your ROR might cause misconceptions. Of course, a 2K$ bankroll will have a much higher ROR than a 20K$ one, but ruin in the first one means only losing 2K and ruin in the second example is losing 20k! you are just as likely to win/lose any given amount of money with any bankroll, provided of course the loss is smaller than your bankroll. (sorry for stating the obvious but I also got misled as I started as well).
Also if you look at this from a return on investment perspective, then about half the time, when a player remains mostly up, his bankroll isn't used, which is inefficient. The optimal way it seems to me to optimize the return on investment is to start with a small bankroll and increase it in case of losses (or stop).
To be honest I have never even thought of what my bankroll is, I guess I stayed well within the SD and never had to ask myself. Am I missing something? is the bankroll a figure in your mind or does it have to be money you are actually able to put in the game? why would having that money bring you any advantage (such as lower risk of losing)?
Lemme know what you all think :)
One could argue bankroll management is only critical if losing it in totality is a life changing moment. Most of the time this never happens. People quit playing until they are able to add to their remaining monies. The idea of winning back their losses by betting 25% of the wager that lost it is all to frightening. There is the theoretical simulated world of blackjack and there is the real blackjack world of unending toil.
