Every player's chance of finishing 1 st is proportional to the player's chip count.

The original ICM model operates as follows: The Malmuth-Harville model also gives poor estimates for unlikely events, and is computationally intractable with many players.

In addition to the payout structure, a Malmuth-Harville ICM calculator would also require the chip counts of all players as input, which may not always be available. Such simulators rarely use an unmodified Malmuth-Harville model. When discussing a deal, how much money each player should get.The range of hands that a player can call another player's all in with or move all in over the top and which course of action is optimal, considering the remaining opponent stacks.The range of hands that a player can move all in with, considering the play so far.An ICM can be applied to answer specific questions, such as:

Poker players often use the term ICM to mean a simulator that helps a player strategize a tournament. The model then approximates this probability distribution and computes expected prize money.

In the ICM, all players have comparable skill, so that current stack sizes entirely determine the probability distribution for a player's final ranking. David Harville first developed the model in a 1973 paper on horse racing in 1987, Mason Malmuth independently rediscovered it for poker. In poker, the Independent Chip Model (ICM), also known as the Malmuth–Harville method, is a mathematical model that approximates a player's overall equity in an incomplete tournament.
