# Thread: Cacarulo: Composition-dependent indices for Insurance

1. ## Cacarulo: Composition-dependent indices for Insurance

Since this question has been asked several times on the free pages I've decided to post the analysis over here.

Let's start with a 6D game and a TC'ed system like Hi-Lo. Normally a "one-fit-all" index is used disregarding the player's hand composition. Let's call this index: Generic Insurance's index (GII).
Of course, it's possible to generate an index for each hand composition as you'll see below.

Generic Index = +3.01 (GII)

Now, let's separate the Hi-Lo tags into four categories:

T = Ten
A = Ace
Z = 7,8,9
L = 2,3,4,5,6

These 4 categories make 10 different indices:

A,A vs A = +2.37
A,Z vs A = +2.57
A,L vs A = +2.73
T,T vs A = +3.28
T,A vs A = +2.82
T,Z vs A = +3.01
T,L vs A = +3.18
Z,Z vs A = +2.76
Z,L vs A = +2.92
L,L vs A = +3.09

Suppose the count is exactly +3 and you're playing heads up: you have 15 and the dealer has an Ace, would you insure? Obviously the answer depends on the composition of the hand. If my hand is 10,5 I won't insure but if it is 9,6 then I will.

Here are the indices for 1D and 2D:

Indices for 1 deck:

Generic Index = +1.41

A,A vs A = -2.42
A,Z vs A = -1.32
A,L vs A = -0.26
T,T vs A = +2.95
T,A vs A = +0.09
T,Z vs A = +1.31
T,L vs A = +2.36
Z,Z vs A = -0.22
Z,L vs A = +0.84
L,L vs A = +1.90

Indices for 2 decks:

Generic Index = +2.38

A,A vs A = +0.46
A,Z vs A = +1.02
A,L vs A = +1.53
T,T vs A = +3.16
T,A vs A = +1.76
T,Z vs A = +2.36
T,L vs A = +2.86
Z,Z vs A = +1.58
Z,L vs A = +2.09
L,L vs A = +2.60

If you're good at memorizing indices then go ahead and learn the above. It's also good cover when you're playing two hands.

I consider this post so informative that I have actually printed it out -- something I do maybe twice a year!!

Nice work, Cac!

3. ## Norm Wattenberger: Oh nooo

Had no idea the differences would be so large. Now I'm going to have to add this to CV.

Great study.

That would be great.

Thank you!

Thanks Don!

Thanks for the good info. Would these indicies be "transferrable" to other counting systems? Especially AOII and Revere Systemic?

If not, how could the computer illiterate (me) make adjustments?

Thanks again.

They're not "transferable," per se. But, they can be calculated for any count.

Of course, you'd have to tell us what the "Revere Systemic" is, since there is no such count. :-)

RSC is listed among many others in Mr. Schoblette's book "Best Blackjack".

Quite simple...2-7 = +1, 8 = 0, 9-A = -1. From memory, betting correl. 95%, and play about 56%.

I recently switched to RSC for 6D, and on a recent Tunica trip used it for DD with Satisfactory results. Certainly simple to use. On face-up games, can "count" the table in seconds.

Again, would appreciate info. of this "Composition Dependent Insurance", as to adjusted to RSC and AOII.

Thanks

I think you are talking about the Silver-Fox system here.

Silver-Fox is not a good system for 6D. Hi-Lo does much better and you don't need to count 7's and 9's. KO is even better.

It's possible to generate insurance indices for AO2 but a level-2 system needs more indices than a level-1 system. Note tha Hi-Lo uses 10 extra indices and that's already hard to learn.
Now, if you still want the AO2 indices just let me know the number of decks.

Cacarulo
