ICM poker explained

ICM, short for Independent Chip Model, is one of the key ideas that separates tournament poker from cash games. It tells readers that tournament chips are not worth cash in a simple linear way once payout pressure starts to matter.

What ICM means

ICM is a way of translating tournament chip stacks into prize-equity pressure. The short version is that doubling your chips does not necessarily double your real-money expectation, especially once payouts become meaningful and survival has value of its own.

Why chip value is not linear in tournaments

In cash games, chips are much closer to face value. In tournaments, payout ladders distort that relationship. Losing chips can hurt more than gaining the same amount helps, especially on bubbles and at final tables. That is why an all-in call that looks fine in chip EV can still be bad in ICM terms.

ICM matters because tournament poker is not only about accumulating chips. It is also about how those chips translate into survival and payout pressure.

Where readers feel ICM most strongly

  • Near the money bubble.
  • In satellite tournaments where survival matters more than first place.
  • At final tables with steep payout jumps.
  • When medium stacks face wider stacks who can pressure them.
