He also wrote a gambling column in the late 1970s and 1980s, which was featured by several newspapers, including The New York Daily News, The San Francisco Chronicle, The Orange County Register, The Los Angeles Herald Examiner, and The Atlantic City Press Besides his work as an author, Patterson has also conducted clinics in blackjack, and he collaborated with Will Cantey and Herb Maisel to build the first blackjack computer simulation model.
This model was used to validate the card counting methods published by Ed Thorp and Julian Braun in Beat The Dealer.
Patterson discussed this model on a panel with Ed Thorp, Julian Braun and other gambling notables at the 1964 Fall Joint Computer Conference.
Since most of Patterson's clients and book readers are recreational, short-term players, he published a special report advising them of the potential impact of these new rules on their blackjack play.
Patterson also responded to these restrictive new blackjack rules by developing (with Eddie Olsen), a non-counting strategy called TARGET 21.
