KO

The KO (Knockout) count is a single level, unbalanced card counting system that is very simple and yet remarkably powerful. In the Knockout card counting system, all card values are the same as in the Hi-Lo system, except that sevens are counted as -1.

This imbalance eliminates the need to calculate the true count from the running count. The starting number for the running count, which is called the initial running count (IRC), varies according to the number of decks being used.

The KO System, or the Knockout count, was popularized in the book Knockout Blackjack by Ken Fuchs and Olaf Vancura. This blackjack book is a good introduction to card counting which also includes a the history of card counting, good blackjack tips and tricks, and much more.
