Blackjack teams: a new way to break Casinos.

Card counting blackjack teams are formed for a number of reasons. Initially, as the number of blackjack card counters skyrocketed in the early 1960's, Las Vegas casinos changed their blackjack rules to protect themselves from what they saw as an invading army of cheating players. Counting cards at blackjack is not cheating, and it isn't against the law. It's just expert play. Casinos don't like expert play. They like bad players with lots of money. And, as it turns out, with most of the new players who read about card counting in Edward O. Thorp's Beat The Dealer, that's exactly what they got - players with a rudimentary understanding of the game of blackjack and plenty of cash. Most went home broke.

However, like Thorp himself, there were some who made a little money after perfecting their play. Since the number of 21 players increased tremendously but the number of players who had really learned card counting was small, the casinos made more money and they relaxed the rules again The best players tried to figure out how to increase their winnings and keep from betting barred from playing.

So basically: More players= less probability of getting broke.

The most famous one is the MIT team:

These team used their mathematical skills as students and ex-student of the MIT to break the casinos using card counting techniques and using more advanced strategies with only one goal that they share with almost every other Team: Beat the Casinos these team won 4-5 millions in a few years aroud the 1970´s.
