Kjw,
Brh-I is Halves doubled, except the '9' is counted as zero.
It is unbalanced, but may use either the running count (in which case it is similar to Uston SS) or the full unbalanced true count mode.
Using the unbalanced true count, it outperforms Halves mainly I believe because of is higher insurance efficiency. Strictly speaking, its linear betting correlation is less than Halves(98.8 vs 99.3), but we know now that raw BC based on basic strategy effects of removal, are at best a rough guide to the power of a system. The same principle applies to AOII vs HiOptII where HiOptII also does not count the '9'. AOII with ace-side count has a much higher BC than HiOptII with ace-side, but again the insurance efficiency seems to tip things the other way. HiOptII is clearly better than AOII, especially in shoe games.
Brh-II is the unbalanced hybrid between HiOptII and AOII, and too does not count the '9'. It performs equally well as HiOptII with ace-side count, but it also has a A=-2, 3=+1, 5=+1, secondary count option to transform it to Brh-I for betting. Since Brh-II is a playing optimised system, it normally is used in true count mode only.
A very interesting quirk I have only recently discovered though, is that since the true count divisor does not vary that much in single deck, it is possible to use Brh-II in running count mode alone in single deck. With an uncompensated (A=-2) ace side count it outperforms both true count Halves and Brh-I. With the secondary count in running mode it actually outperforms true count AOII!
Both systems will be available in a month, give or take, in the Brh Systems Booklet which will sell for $30US.
Cheers,
Brett.
