The group combined individual play with a team approach of counters and big players to maximize opportunities and disguise the betting patterns that card counting produces. In a 2002 interview in "Blackjack Forum" magazine, John Chang, an MIT undergrad who joined the team in late 1980 (and became MIT team co-manager in the mid-1980s and 1990s), reported that, in addition to classic card counting and blackjack team techniques, at various times the group used advanced shuffle and ace tracking techniques. While the MIT team's card counting techniques can give players an overall edge of about 2 percent, some of the MIT team's methods have been established as gaining players an overall edge of about 4 percent. In his interview, Chang reported that the MIT team had difficulty attaining such edges in actual play, and their overall results had been best with straight card counting.
