ICM in poker: why your chips aren't worth what you think

The Fundamental Problem With Tournament Chips

In a cash game, every chip has the same value. In a tournament, chip value is non-linear. Doubling your stack does NOT double your tournament equity. This is the core insight of ICM — the Independent Chip Model.

Why Chips Lose Value as You Gain Them

Imagine a 3-player Sit & Go with prizes of $50, $30, $20. All three start with 1,000 chips. Each player's starting equity is about $33. If Player A doubles up to 2,000 chips, their equity becomes roughly $43 — not $67. The extra 1,000 chips only added $10 of equity because you can't win more than first place.

How ICM Changes Your Decisions

On the bubble, ICM pressure is strongest. Big stacks should attack relentlessly since they can't bust. Medium stacks should avoid marginal confrontations. Short stacks should either find a spot to shove or wait for shorter stacks to bust. Classic ICM spot: you have A♠Q♠ on the bubble, a big stack shoves. Chip EV says call. ICM says fold — because busting costs you the guaranteed min-cash.

When to Ignore ICM

ICM isn't everything. Very early in the tournament when pay jumps are far away, chip accumulation matters more. And heads-up, ICM is irrelevant — it's pure chip EV. Use our ICM calculator to study specific spots and build intuition over time.
