KO System: the Unbalanced Counting System for Blackjack Players

All blackjack counting systems are divided into 2 types:

  • Balanced counting systems: when you use them you should start your counting with 0 and end it with 0 too.
  • Unbalanced counting systems: you start counting with 0 but it is usually not ended with 0.

KO system is considered to be the unbalanced counting system but this fact does not make it being less profitable for those gamblers who use it: as well as Hi-Lo card counting, KO system is easy to understand and practice for beginners. KO means Knock Out, and its principles are the same with general card counting strategy: to add or subtract 1 point during the game of blackjack and predict which cards are left in a shoe.

How to Count

The only difference between KO system and Hi-LO card counting is the fact that KO system does not count 7's being neutral cards - they are counted as +1 here.

Look at the table below and try to remember how to count cards according to KO counting system:

Thanks to the fact 7's are counted as +1 here, KO system is proven to be unbalanced: the final result you will get after the last card is dealt from a shoe will be not 0 but +4.

When you count cards with the help of KO system remember the following thing: your count will depend on the number of decks blackjack is played with: for example, if you play blackjack with 6 decks of cards and your count is +6 at the moment you should divide your count into 6; your final count will be +1 then.

Note! Do not forget to count all cards, not only yours. Remember, that other players and a dealer also gamble at the moment.
