The Independent Chip Model (ICM) is a way of calculating the right decision when playing the bubble in Texas Hold'em tournaments.
A = Player 1's Stack
B = Player 2's Stack
C = Player 3's Stack
T = Total chips in play
A * .5 + B * (A * .3 + C * .2) / (A + C) + C * (A * .3 + B * .2) / (A + B)) / T
ICM assumes that each player's chance to win, ability being equal or indeterminable, is proportional to his/her stack size. Chances to come in other positions can be calculated conditionally, allowing an assessment for each player of their equity at any point.
