* The new reversed card counting strategy considers the minus (negative) count, as opposed to the "traditional" plus-c(o)unt systems. The negative counts are far more favorable to DOUBLE DOWN hands, the most advantageous situations for blackjack players. There is a high percentage of double down sequences: 4+6, 5+5, 5+6, even 3+6, 4+5. Or, 9+2, 8+2/3, 7+2/3/4/A.

* We simply count the Ten-valued cards as 1, 2, 3,.., as they are dealt. We don't have to remember the previous rounds. We don't even count the Aces, as they become also 1-values (serving the purpose of doubling down).

What you gonna do, casinos? Hire new "consultants" to chase the 'reversed counters'?

Play also an original blackjack system for beginning-of-shoe only.

It is a mathematical fact that the beginning of a shoe favors the player. There is a 4.8% chance for a blackjack natural and an 8% probability for a double down hand. That's because the player is paid 1.5 times or 2 times the initial bet, while the dealer is always paid 1 to 1. Also importantly, the player will not bust in those two case scenarios, while the dealer can bust.

Now, keeping track of the Tens-only serves a good purpose as regards INSURANCE BETTING.

• In the ‘Counting System In-Reverse’: The larger the amount of Tens OUT (removed), the higher degree of certainty DC to get a DOUBLE-DOWN hand in the next round.
• Inversely, for the ‘Insurance Bet’: The larger the amount of Tens LEFT (REMAINING) in THIS round, the higher degree of certainty to win the ‘Insurance Bet’.
• We consider the cutoff value to be ONE THIRD of Tens removed from the deck. There are 2 cards per hand for each player and the dealer. Total cards dealt: 16.
• For example, if there are 7 players plus the dealer, the cutoff value is 16/3 = 5 Tens OUT in the first two cards.
• A ‘positive’ (favorable!) count is everything UNDER the cutoff value. In the example above, if the ‘10-count’ is (5 – 2), it is recommended to take insurance.
• A ‘10-count’ figure of 5 or above: Do not take insurance (house advantage is 12% on average).

INSURANCE can be a favorable bet for all blackjack players depending on the number of Ten-value cards seen on the table. For example:

7 Players:
• Take insurance if 3 or fewer Tens came out in the running round.

6 Players:
• Take insurance if 2 or fewer Tens came out in the running round.

5 Players:
• Take insurance if 2 or fewer Tens came out in the running round.

4 Players:
• Take insurance if 1 or no Tens came out in the running round.

There is no doubt that the negative counts are more favorable to the blackjack player than the positive counts. Reason: potentially more double down hands. The Tens can never form a doubling down hand.

But don’t get me wrong. I never meant this sui generis card-counting system was an automatic winner. It is prone to the same drawback as the “traditional” card counting systems: There are more losing sequences compared to the winning situations. Card counting is like a cult: The “faithful” must increase the bet in ALL “favorable” situations. The bet increase is automatic, but the counting reality is not. There are more losing situations than winning cases!
