After that Dr. Edward Thorp published in “Beat the Dealer” its strategy for blackjack, many players realized that his counting system was too complex to include it in the game. But it must be acknowledged that the publications of that book awaken the cunning of other players who began to develop their own blackjack strategies and less complex counting systems.
This was how systems such as counting systems of five were born, where it was required only to be counting how many cards with that number remaining in the deck. If there were fewer than half the 5, the game would be favorable to the player; therefore he should raise its bid.
Also emerged some strategies of blackjack somewhat more advanced, but continued being even simpler than Thorp’s system, because these not required the use of arithmetic in order to implement them. In fact, it was only required concentration and to pay attention to all cards. The idea was to count and record cards previously in order to decide whether the deck could be favorable or not. One strategy that can easily be used today in a game online blackjack.
Then would arouse the famous computer simulations, which allowed to simulate up to a million hands. This gave the opportunity to make comparisons between different real blackjack strategies and their possible results in the same hand.
These are simple examples of the myriad of systems, methods and strategies of blackjack that exist. It is very important for any player appropriating one. Learning to use it to perfection will avoid major losses in the long run. Besides, once attained certain level of the game and gained some practice, can opt for any system or strategy for blackjack players, which will allow you to increase your profits in the future.

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.
