Sorry, the Cac/71 tags are -2 2 2 2 2 2 1 0 0 -2 and not -2 2 2 2 2 2 1 0 -1 -2 as I put in my previous post. You need to get the insurance index from this count which is the one used for betting purposes.

Sincerely,
Cac

The main idea of this system is to not complicate things. Cac/7 or Cac/71 is for people that are used to Hi-Lo indices and that do not want to learn a new set of them. However, Cac/71 (-2 2 2 2 2 2 1 0 0 -2) does incorporate an index exception for insurance. The index would be +2 instead of +3.
The reason for this is that the IC increases from 0.7885 (Hi-Lo) to 0.8101 (Cac/71).
If you were to halve the Cac/71 tags you can use +1 instead of +2.
You are free to incorporate more exceptions but that would be another system.

Sincerely,
Cac

Was the ace counted as neutral in all playing decisions, or selected playing decisions?

thank you

Yes, the ace was counted as neutral in all playing decisions (Catch-22). Only for betting purposes it was counted as -1 (Hi-Lo).

Hope this helps.

Cac

Thank you very much for your response.

The technique you used is certainly the traditional one. It is the one suggested by Wong in his early editions of Professional Blackjack.

After much reflection, however, I am skeptical that this technique optimally employs ace information for playing strategy.

Would you agree, for example, that for hard doubles on 10, 9, and 8 the ace would most appropriately be valued as -1? Indeed, rather than neutral, the ace is even more valuable than the 10 on these hands.

These plays comprise 6 hands of the Catch-22.

If you agree, revised SCOREs using this strategy would be of interest.

Thank you.

No, I don't use Wong's technique. My method is the one used for unbalanced counts played in TC mode. Besides, I use different indices due to the imbalance of the count.

Your guess is correct. It does not optimally use the ace for some of the plays.

Agree.

Correct.

Of course it would be better but my software in its actual state can't use different systems for different plays. It can use one system for betting and another system for playing. However, in Cac/71 I do make an exception for insurance. Don't know if the newest version of CVdata can handle more plays.

You're welcome.

Sincerely,
Cac

"No, I don't use Wong's technique. My method is the one used for unbalanced counts played in TC mode. Besides, I use different indices due to the imbalance of the count."

This is still a hilo count, however? Or applied to a hilo count? My question pertained to the "Hi-Lo/A" count you cited in your table.

"Of course it (using values in addition to neutral for the ace in playing strategy) would be better but my software in its actual state can't use different systems for different plays."

I see. That's a problem.

Thank you very much for the response.

His response: "You can use the multi-parameter tables."
