An author of several gambling books (such as Professional Blackjack, first published in 1975), Stanford Wong had an analytical approach to his card playing. He even released a blackjack hand analysing software program in the early days of computing. Some would say he was ahead of his time.
He came up with a technique, known as ‘Wonging’ which involved watching rather than waging until finally betting when the count is in the players favour, and only during that time. His technique was so successful that casinos now typically have a “No Mid-Shoe Entry” sign up, forcing them to play directly after a shuffle rather than at a time of their own choosing.
At one point he finances a team of advantage players that would play card games at various casinos across Las Vegas. His last contribution as an author is the Complete Idiot’s Guide to Gambling Like a Pro.
