After Thorp designed in 1962 a system of counting letters known as “High and low,” there was additional work that was done by one of the forgotten characters of blackjack, Harvey Dubner. This man was the one who invented the system of counting blackjack points. That system then lead to the publication of over a hundred books with theories and systems for winning at blackjack, blackjack teams were formed, computer systems and methods of mixed tracking.
But if what Dubner did was so important, why is that it has not been recognized?. The truth is that by 1962 Thorp had already published the first edition of “Beat the Dealer”, but the public was avid for blackjack system much more simple, one that everyone could implement without mathematical knowledge. The following year in Las Vegas the Computation Conference was lead out, an event in which the organizers decided to include a panel on “The Use of computers in gambling.” There Thorp was the chairman of the panel and invited Dubner to participate with the description of his method of counting points High / Low.
The following year Thorp published the second edition of his book, where he decided to include this blackjack system by Harvey Dubner. It may be recalled that the method of counting points High / Low is currently used by the vast majority of players that use some blackjack system, including the online blackjack. This happens thanks to the simplicity and practicality of the system introduced by Dubner and then popularized by Thorp.
