ICM
Context: Poker term: ICM ICM (Independent Chip Model, 独立筹码模型) is a mathematical model used in Texas Hold'em tournaments to calculate the real value of chips. It converts chip counts into corresponding prize expected value based on the chip distribution and the number of remaining players. Its core purpose is to evaluate the true monetary value of different chip stacks under the prize structure, rather than just the raw chip count. In practice, ICM is often used for decisions on the final table or near the money bubble, such as whether to risk an all-in or fold, because the marginal value of chips decreases — the potential gain from accumulating more chips may be outweighed by the risk of elimination. Understanding ICM helps players make more rational fold or raise decisions under tournament pressure, avoiding premature elimination due to over-aggression.
What is ICM?
ICM (Independent Chip Model) is one of the most important mathematical concepts in tournament poker. It converts a player’s chip count into real monetary Expected Value ($EV).
Why is ICM Important?
In tournaments, 1 chip does not equal its face value. When you are near the money or the Final Table, preserving chips is often worth more than taking risks.
Common Applications
- Bubble phase strategy: Tighten up when approaching the money
- Short Stack Push/Fold: ICM pressure affects Shove ranges
- Final Table Deal: Use ICM to calculate fair distribution
Simple Example
A 10‑player tournament has 4 left, with a total prize pool of $1,000. You hold 40% of the chips, but ICM calculates your Expected Value as only $350, not $400.
