Hi-Lo with an Ace side count

[Cacarulo]

Side Count technique

Let's take Hi-Lo/A as an example. For Hi-Lo, the Ace is assigned a value of "-1" and this is the best value it can take for
betting purposes. Unfortunately, "-1" is not the best value for playing decisions, so it would be better if it was "0" or "1",
as it would improve the IC and PC/PE of the counting system.

Let's look at some correlations:
  
A = -1
BC: 0.9665
IC: 0.7647
PC: 0.7618 (only considering R22 plays)
  
A =  0
IC: 0.8674
PC: 0.8219 (only considering R22 plays)
  
A = +1
IC: 0.8908
PC: 0.8039 (only considering R22 plays)
  
Taking these correlations into account, we can say that the ace should take the value of "-1" at betting time, "+1"
for insurance and "0" for other plays.
 Now, let's move on to the implementation of the technique. Let's call the primary counting system "pc" and the
secondary counting system "sc".
  
        A  2  3  4  5  6  7  8  9  T
  pc =  0  1  1  1  1  1  0  0  0 -1 (irc = -4 * decks)
  sc = -1  0  0  0  0  0  0  0  0  0 (irc = +4 * decks)
  
Here we must decide what suits us best, if the Ace should be worth "0" or if it should be worth "1" for playing decisions.
According to the following SCOREs we can say that it is more convenient for the Ace to take the value of "0".
The game conditions: 6D,S17,DOA,DAS,SPA1,SPL3,NS,4.5/6,R22 indices (Revisited Catch-22: TTv4 replaces 10vT)
  
Hi-Lo/A=0
1-12: 22.53
1-16: 26.42
  
Hi-Lo/A=1
1-12: 22.38
1-16: 26.27
  
Note that for the same game conditions, Hi-Lo by itself has the following SCOREs:
  
Hi-Lo
1-12: 21.15
1-16: 25.00
  
How to use pc and sc
We start both counts with their respective irc. Assuming 6D we would start at “-24” for pc and “+24” for sc.
For playing we will use pc and for betting we will use pc + sc.
  
insurance:Here we can make an exception and use the Ace as +1. For doing this you have to use pc – sc (instead of pc).
  
Indices
The ideal is to generate a new set of indices for the primary count (pc) but if you are used to the Hi-Lo indices simply
subtract 4 from each Hi-Lo index.
For insurance you can subtract 8 from the Hi-Lo index if you decided to count the Ace as +1.
  
Note: The SCOREs above are for the Ace counted as 0 for ALL playing decisions. If we made the exception for insurance,
it would be much better.
  
Enjoy!
