Why chips aren't equal in tournaments and how it changes every decision.
In a cash game, every chip is worth exactly its face value. A $10 chip is worth $10. Tournaments are different. Because of the payout structure, the value of each chip changes based on your stack size relative to others and how close you are to a pay jump.
The Independent Chip Model (ICM) converts chip stacks into real-money equity. It answers the question: "Given everyone's stack sizes and the payout structure, how much is my stack worth in real dollars?"
Imagine a tournament with 3 players left. Payouts: 1st = $1000, 2nd = $600, 3rd = $400. All three players have equal stacks of 10,000 chips.
Each player's ICM equity is ($1000 + $600 + $400) / 3 = $666.67. Now imagine you double up to 20,000 while one player is eliminated. You now have 20,000 and one opponent has 10,000. Your ICM equity isn't $1333 (double $666.67). It's about $850. Doubling your chips only increased your equity by ~28%, not 100%.
This is the core insight: the chips you gain are worth less than the chips you risk. Losing your whole stack costs you everything. Winning someone else's stack doesn't double your equity. This asymmetry drives all ICM-aware decisions.
The biggest ICM pressure happens at the bubble — when one more elimination puts everyone in the money. If 100 players remain and 99 get paid, every player has significant equity just by surviving. The short stacks can't afford to gamble, and the big stacks can exploit this by applying pressure with wide ranges.
Use our ICM Calculator to compute exact equity for any stack distribution and payout structure.
ICM assumes all players are equally skilled, which is never true. Strong players have higher real equity than ICM suggests because they'll outplay opponents in future hands. ICM also doesn't account for blind levels, position, or the dynamic nature of tournament play. Use it as a guide, not a gospel.
