The counting system Wong published was the Hi-Lo Count, and like Revere’s count, used the easy divide-by-remaining-deck approach to running count adjustments. So, at last, some twelve years after Harvey Dubner had proposed the Hi-Lo count values, his system was available in a format both fully optimized with blackjack strategy indices, and presented with a simple methodology of play. This playing style has since become widely known as wonging.
Finally, Stanford Wong came out with a book called Professional Blackjack. Wong had a Ph.D. in economics from Stanford University, hence his pseudonym. This book was the next big advance for card counters. Wong described his playing style, which included table-hopping shoe games to avoid playing at negative counts. The casinos looked for card counters by watching for their betting spreads. It had never occurred to the casinos that a counter might be watching a table from the aisles, waiting for an advantageous count before jumping in to bet.
