Blackjack card counting systems

From Encyc

Blackjack, or Twenty-one, is the most popular casino game. With the development of the personal computer, players, including mathematically skilled individuals who had used brute force methods to develop systems to win at the game, found that computer-developed systems provided a distinct advantage.

In the 1960's, blackjack became the most popular of casino games after computer-based systems were developed which gave an edge to the player. Various mathematicians and gamblers including Edward Thorp and Les Golden have refined these systems.[1][2][3][4][5]
