This is a strategic guide by Arnold Snyder, treating blackjack as a "martial art (Blackbelt)." This book is a 1990s English edition and is an important book for understanding blackjack counting theory at the time. Although it deals with the now-uncommon Red 7 Count, it is known as one of the first books to systematically introduce unbalanced counts. Furthermore, it goes beyond a simple explanation of counting methods, including early mentions of shuffle tracking, and other advanced content for its time. In the 1990s, many Japanese counters directly read and studied these overseas strategy books, and this book is a valuable resource that reflects that background. The Red 7 Count introduced in this book is the foundational concept for unbalanced count theories, such as the later K-O (Knock-Out) count. While not for everyone due to being in English, it is recommended for those interested in the history of blackjack strategy and counting theory. Condition: Due to being a book from the 90s, there is some age-related deterioration, but there are no tears, writing, or major stains, and it is readable without issue.
