Re: singledeck & BrhII

Yes, not only in single deck mind you, running count Brh-II plus ace-side count seems to be able to give full true count Brh-I a run for its money as well in shoes.
As for SD, here are some sims, the rules are a bit lenient with S17, DAS, with four rounds to two players, but other rule sets seem to behave the same way. I can't quite remember the spread, I think it was 1-4 optimal play all. The figures on the right correspond to a $10000 EKB, so that the EV/100 figure is equivalent to SCORE.

So, HiOpt-II with ace-side count is still the best, but notice that running Brh-II with running secondary actually outperforms full true count AOII with ace-side. Running Brh-II with ace-side is just behind true AOII but still ahead of true Brh-I. Incidently other sims I have run put running UBZ11 up there near true Brh-I in single deck only as well. The (nsec) run refers to using running Brh-II without any ace count. There is a third option not shown, where instead of doing a full ace-side count, only an ace subtraction is done (no richness or poorness adjustment) for betting. This works in single deck only, because the negative unbalance of the subtracted count is partly compensated by the positive unbalance of Brh-II itself. This combination still wins more than true Brh-I or running UBZ11 in SD only.
I have become a big fan of UBZ11, if I never wanted to ever compute a true count, or compute a side count, I think I would use it for all decks (with different indices of course). The only downside is that for shoes Brh-0 or Brh-I leap ahead once true count conversion is done. Its just that in SD, true count conversion is not that important! But the other thing I like is that running Brh-II with ace-side, can be seen as a natural upgrade for existing UBZ11 players. The tags are very similar indeed, except for the ace, and the '3'.
