Independent Chip Model (ICM) is a mathematical framework used to estimate each player’s equity in a tournament based on their chip stacks and the remaining prize payouts. It treats chips as shares of the remaining prize pool, assuming that each chip has an equal chance of becoming a winning chip.
In a twoβplayer bubble situation, only the first and second place prizes remain. The ICM simplifies dramatically because each player can only finish first or second, so the probability of finishing first is simply the proportion of their stack to the total chips in play.
The equity for a player can therefore be calculated directly from their stack size and the prize amounts. This provides a quick way to assess whether a call or fold is profitable in the critical bubble stage.
