ICM
ICM Is Not a Final Table Concept
Waiting until the final table to think about ICM means you have already given away the chips that would have got you there with a stack.

Ask a field of mid-stakes tournament players when ICM starts mattering and most will say the final table. A few will say the bubble. Both answers cost money, because the honest answer is: the moment a non-flat payout structure exists, which is to say, from the first hand.
What ICM is really measuring
ICM says something simple and slightly annoying: chips you win are worth less than chips you lose. Double your stack and you do not double your equity in the prize pool, because you cannot win more than first place. Lose your stack and you lose all of it.
That asymmetry does not switch on at the final table. It is a property of every tournament with a tiered payout, running the entire time. What changes is the magnitude.
Where players actually lose the chips
The classic ICM disaster is a bad call on the bubble. But the quieter, more expensive version happens hours earlier:
- Flipping for a marginal edge in the early levels. A coin flip that is 51% in chip terms is a loser in equity terms. Early, the effect is small, but you take this spot repeatedly.
- Over-defending a big stack. Having chips does not entitle you to gamble them. It changes which risks are cheap, not whether risk has a price.
- Playing the middle stages like a cash game. The whole point of a tournament is that you cannot rebuy your way back to relevance.
The practical reframe
Stop asking “is this +EV in chips?” and start asking “is this +EV in money, given the stacks left and what is left to pay?”
Those two questions give the same answer in a lot of spots. When they disagree, the disagreement is where the money is, and it is almost always the chip-EV answer that is wrong.
Risk premium, in one sentence
Risk premium is the extra equity you need above a chip-EV break-even call, purely because busting is expensive. When you are the short stack it is small. When you are the second-biggest stack at a table with a very short player about to bust, it can be enormous: large enough to turn a clearly profitable chip-EV call into a clear fold.
If you take one habit from this: before you call off, ask who else at the table is about to bust. Their tournament life is part of your decision.
