After the basics are coveredin this book, Wong moves on to explain the High-Low system, which is one of the most popular counting systems available. Although the High-Low system is associated with Wong, he wasn’t the one who invented it, but rather, he was the first one to research the system and publish the findings.

Professional Blackjack also explains in great detail how the system works, describing also taking insurance, what the edge is and how the strategy changes with a wide variety of game rules. Just like Revere’s count, this system uses the easy divide-by-remaining-deck(s) approach to adjust the counts. Harvey Dubner proposed the system several years earlier, but only Wong was able to present the system with a simple methodology, in a format optimized with strategy indices.

In this book, Wong also describes his playing style - often referred to as Wonging - that includes table-hopping shoe games to avoid playing at negative counts. The most popular game in Las Vegas at that time was four-deck shoes; allowing brilliant space for the different approach to blackjack. Casinos looked out for card-counters only by looking at the players at the table. Little did they know that Wong’s system didn’t require a player being at the table, but rather in the aisles, waiting for an advantage count before joining the game!

This system of table-hopping to shoe games, is quite similar to Al Francesco’s Big Player team approach, with the main difference being that Wong’s provided a solo counter to attack shoe games without notice and without the help of teammate spotters.

Moreover, Professional Blackjack also includes 100 pages of charts that show computer simulations of hands and situations, initial hand frequencies, win rates of various games, a glossary and a bibliography. As you can see, this book is very thorough, and although it does not cover issues like betting structures, it’s quite useful to read if you want to take your Blackjack skills to a higher level.
