This is the book that describes the system I use. It features the simple yet powerful KO counting system. I thoroughly enjoyed the great little side stories. Contained in the book are different level systems. From KO rookie to KO preferred the systems are designed for use from the casual user to the pro.

An excellent book for any player looking for one of the easiest and strongest professional-level systems ever published.--From Arnold Snyder, Blackjack Forum

K-O is a simple and powerful card-counting system...clearly and entertainingly presented.--Edward O. Thorp Ph.D. Author of Beat the Dealer
