"The Jazbo/Sorokin formula is nice, I use it a lot, but there are three
problems with the Jazbo/Sorokin formula:
1. It assumes play forever. For the non-infinite human timespan you need
something like Dunbar's Risk Analyzer.
2. What do you do if any risk of bankruptcy is unacceptable? In other
words, what if your desired ROR is 0%? Other than an infinite bankroll,
Jazbo/Sorokin has no answer to that question, Kelly does. Kelly answers
the question of how do you play without going bankrupt and on a finite
bankroll.
3. What is an optimal betsize or in the case of Jazbo/Sorokin, what is
the optimal level of risk? Jazbo/Sorokin has no answer to this question,
Kelly does."
In response:
1. Sorokin/Jazbo does not necessarily assume playing forever. Optimum
Video Poker also uses it to calculate Risk of Ruin Before a Royal Flush.
2. What to do if any RoR is unacceptable? Kelly does not answer this
adequately for video poker because it is impossible to vary your bet
size in small increments. The only way to absolutely avoid ruin is,
DON'T PLAY AT ALL.
3. What is optimum (or optimal if you prefer that word) is highly
subjective. My book, Video Poker Optimum Play, provides tools to assist
each player in answering this question for himself. Some of these tools
are implemented in Optimum Video Poker.
How to best use Sorokin/Jazbo? Select a game of your choice and try
Sorokin with your current bankroll and each of the available machine
denominations, then pick the denomination that is most compatible with
your emotional tolerance of risk.
