> * 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.

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).
