The MIT Blackjack Team was a group of students and ex-students from the Massachusetts Institute of Technology, Harvard University, and other leading colleges who used card counting techniques and more sophisticated strategies to beat casinos at blackjack worldwide. The team and its successors operated successfully from 1979 through the beginning of the 21st century. Many other blackjack teams have been formed around the world with the goal of beating the casinos. Blackjack and card counting Blackjack can be legally beaten by a skilled player. Beyond the basic strategy of when to hit and when to stand, individual players can use card counting, shuffle tracking, or hole carding to improve their odds. Since the early 1960s, a large number of card counting schemes have been published, and casinos have adjusted the rules of play in an attempt to counter the most popular methods. The idea behind all card counting is that, because a low card is usually bad and a high card usually good, and as cards already seen since the last shuffle cannot be at the top of the deck and thus drawn, the counter can determine the high and low cards that have already been played. They thus know the probability of getting a high card (10,J,Q,K,A) as compared to a low card (2,3,4,5,6). In 1979, six MIT students and residents of the Burton-Conner House at MIT taught themselves card-counting. They traveled to Atlantic City during the spring break to win their fortune. The group went their separate ways when most of them graduated in May of that year. Most never gambled again, but some of them maintained an avid interest in card counting and remained in Cambridge, Massachusetts. Two of them, J.P. Massar and Jonathan, offered a course on blackjack for MIT's January 1980 Independent Activities Period (IAP), during which classes may be offered on almost any subject. First MIT blackjack "bank" In late November 1979, Dave, a professional blackjack player contacted one of the card-counting students, J.P. Massar, after seeing a notice for the blackjack course. He proposed forming a new group to go to Atlantic City to take advantage of the New Jersey Casino Control Commission's recent ruling that made it illegal for the Atlantic City casinos to ban card counters. Casinos instead have to take other countermeasures like shuffling the cards earlier than normal, using more decks of cards, or offering games with worse rules
