Blackjack Risk Manager (BJRM) is a calculator-type utility program that
automatically and instantly performs several complicated blackjack risk-related
statistical calculations, providing you with the facts you need to manage your blackjack
BJRM can be used to provide the answers to many very important blackjack
risk-related questions, such as:
What is the Risk-of-Ruin of my trip/session, and my total playing bank?
What is my probability of being ahead by $2,000, sometime during my next 16 hours of play?
Exactly how much bank do I need if I am willing to tolerate a 7.5% risk-of-ruin? What if I
change that to 5%?
Within my spread, at which counts do I place the bets in order to maximize the rate of my
What is the $ hourly win rate that a specified game will yield?
How would things change if I got in more hands per hour?
OK, I played 6 hours last weekend, and lost $5,000. How rare of an event was that?
Which is the better game to play, an H17 DAS 2-deck 70 card penetration game,
played all with a 1-6 spread, or a back-counted S17 DAS LS 1-8 spread game
where 4.5 decks of 6 are dealt?
And many, many more just as interesting and illuminating.
Most risk questions can be answered with very little text entry, simply by selecting and
mouse-clicking on the programs built-in choices. To perform many of the
calculations, Blackjack Risk Manager needs to be supplied with only two values: Win Rate
per 100 hands and Standard Deviation (SD) per 100 hands, both expressed in units.
Win Rate and SD values can be readily obtained from several sources, such as: values
published in blackjack literature; values from simulations run by blackjack simulator
programs on the market; and, perhaps most importantly, from two places within BJRM itself!
First, Tab 3 of BJRM has the Win Rate and SD values of over 100 different blackjack game
scenarios, built-in. These feature multiple combinations of decks-in-play, rules,
penetration levels, and bet spreads including back-counting. It is very likely that
one of those combinations is close to the game you are interested in. And BJRM
s built-in Win Rate and SD values are very precise, as they were each calculated
based on actual simulation runs of over 400,000,000 rounds. The Tab 3 values feature a
Hi-Lo player using the Illustrious 18 and Fab 4 strategy
departures, and are, in fact, the actual results from the simulations run for Chapter 10
of Don Schlesingers classic book, Blackjack Attack: Playing the Pros Way.
[Note: If you are not familiar with Dons book, you should be! You will find BJRM to
be an excellent complement to Blackjack Attack, and vice versa]. However, Tab 3 even goes
beyond Chapter 10 data, to include a complete set of data for 8-deck Games!
Second, Tab 4, which I have dubbed the One-Second Simulator, is potentially
even more valuable to the user than Tab 3. The One-Second Simulator allows you to input
your own bet pattern, rather than use the ones detailed in Chapter 10 of BA: PTPW.
Additionally, you can use data from counting systems other than the Hi-Lo, as, currently,
the K-O and the UBZII are also supported. Future releases of BJRM will likely add support
for other systems, as well. Tab 4 also contains a very valuable feature that, when given a
specific bet spread (1-4, 1-12, etc), will automatically compute the best placement of
those bets in order to optimize the growth rate of your bankroll. And it does so
for both play-all and wonging.
I have tried very hard to write Blackjack Risk Manager in such a way as to make a
traditional, hard-copy User Guide unnecessary. In addition to this Help File, BJRM has
very extensive automatic real-time help, in that, as the mouse cursor is
placed over the text and data on the screen, a status line along the bottom
displays all the descriptions and/or instructions you will likely need to put the program
through its paces. And when you are thoroughly familiar with the program (in no time at
all) you can even turn off the status help text, if you like.
So install, and then dig in, explore, and enjoy Blackjack Risk Manager.
You need never be surprised by the ups and downs of blackjack risk, again!
