Why ICM Is the Key to Crushing Poker Tournaments

Is getting more chips the only goal in tournament poker, or is there more to it than that? In the late stages of a tournament, it can feel like you’re walking a tightrope. Because by making a single mistake, you’ll lose all of your chips.

This is why learning the Independent Chip Model (ICM) is essential. You can use ICM to make better decisions even under pressure.

Initially, ICM may seem hard to comprehend, but once you do, it could mean the difference between bubbling and getting a big payout.

What Is ICM?

Ever think about how much your tournament chips are worth? In cash games, chips are worth a fixed amount of real money. In tournaments, however, chips represent your share of the prize pool.

ICM stands for “Independent Chip Model.” It is a mathematical model used in tournament poker to determine the worth of a player’s chip stack at any given time.

ICM considers several factors, such as the event format, payout structure, and the number of players left. By doing so, ICM reveals the risks and rewards of each decision, indicating how your actions could increase your odds of moving up the pay ladder or crushing out of the tournament.

How Does ICM Affect Your Decision-Making?

If you understand ICM, you can change tactics based on the tournament stage.

When you’re close to the money or deep in a tournament, the best ICM strategy calls for a much tighter approach if you’re used to making decisions based on chip value (chip EV).

Consider a scenario where you are playing in a $100 prize pool multi-table tournament (MTT). The payout structure is:

1st place: $50

2nd place: $30

3rd place: $20

You have 5000 chips in the big blind and are the chip leader. You are likely to finish at least third place. Here, your expected value (EV) could be around $35. Nevertheless, you get closer to the money should another short-stacked player bust out.

Your chances of finishing first or second place improve as the field becomes smaller. Hence, your EV may increase to $40 or $45.

This illustrates how ICM affects the value of chips in tournaments: the amount you receive does not directly correlate with your winnings, notably when players are eliminated and prize jumps occur.

If you look at chip EV (expected value), defending your big blind with a wide range of hands makes sense because of the good pot odds.

In a nine-handed game, for example, you might defend almost 69% of your hands against a hijack raise. Here’s the breaks down:

Big Blind (BB) Defense Analysis vs. Hijack (HJ) Raise

Overall Defense Range

Total Hands Defended: 65.7%

Call: 56.3%

Raise: 9.4%

Folded Hands: 34.3%

Strategy Breakdown

Raise (9.4%): Premium hands are played aggressively.

Call (56.3%)Wide range, including suited connectors, broadways, and middle pairs.

Fold (34.3%): Weaker offsuit hands, low pairs, and low-suited hands.

The Chip EV strategy defends more aggressively, as in cash game-like situations, losing chips has no direct bearing on survival.

It focuses on building up chips and includes riskier hands like weak pairs and small-suited connectors that can win big pots after the flop.

However, in ICM circumstances, risk premiums kick in, and players are less likely to jeopardize their tournament lives. In the middle stages, with 17.5% of the field left:

Raise frequency: Decreases to 7.6%, reflecting tighter aggression. Hands, like suited aces (A5s, A6s), are still raised, but more suited connectors and middle pocket pairs are needed.

Call frequency: Drops to 50.6%, folding marginal speculative hands (e.g., T9s, 87s) and weaker broadways (JTs, QTs). The risk of busting is prioritized over chip accumulation.

Fold frequency: Increases to 41.8%, showing more caution. Hands like A5o, KTo, and low off-suited broadways are often folded.

The ICM scenario takes a cautious approach, prioritizing tournament survival over marginal equity. Players defend less since losing chips risk their tournament life.

ICM Preflop Adjustments Across Tournament Phases

ICM encourages players to change their ranges at different stages of the tournament. With a clear guide, these changes are easier to remember.

Preflop charts help you stay ahead of the action. With Poker Academy‘s preflop charts, you can quickly adapt to these ICM changes. For the next charts, we will use simulations with asymmetric stacks to present real-game situations, focusing on the Cutoff (CO) Raised First In (RFI). The stack distribution in this spot is as follows:

Early Phase (50% of the Field Remaining)

Now that half of the field is left, players are less afraid of taking risks and focus on getting more chips. Ranges get wider, and players become more aggressive in building stacks.

• All-In Frequency:8%
• Raise-Only Frequency:5%

Key Adjustments:

Wider Ranges:

• More suited aces (A2s–A5s) and weaker pairs (55, 44) are raised as players embrace higher-variance plays.

Lower offsuit broadways like KTo and QTo are included, signalling a broader opening range.

Players should occasionally shove small pairs such as 22–33 to leverage fold equity and look to accumulate chips.

25% of the Field Remaining

When only 25% of the players are left in the game, hand ranges get smaller, so survival is more important than aggression. The raise-only frequency stays at 26.3%, while the all-in frequency decreases slightly to 3.6%. As pay jumps get bigger, the focus changes to lowering risk and avoiding marginal spots.

• High pocket pairs (TT+) and strong broadways (AK, AQ, KQ) dominate the ranges.
• Suited connectors and weaker offsuit broadways (e.g., AJo, KTo) see limited inclusion.
• Marginal hands like A2s–A5s and low pairs (55) are rarely raised due to unfavorable risk-reward dynamics.

Direct Bubble Stage – ICM-Driven Tight Play (22bb CO RFI)

As players try to stay alive and enter the money, the Direct Bubble Stage adds a lot of ICM pressure. Strategy gets much tighter, shifting focus to strong, selective hands.

Raise frequency 20.6%: Hands like suited connectors, such as KTs-QTs and off-suit broadways, are raised to apply pressure without committing entirely.

All-In frequency 6.4%: Hands such as AA, AKs, AQs, AJs, ATs, and mid to low pairs like 66-99 are recommended for shoving to maximize fold equity and capitalize on strong hand potential.

Fold frequency 72.9%:Hands like 22–44, and weaker-suited gappers (54s, 76s) are folded to reduce bust-out risk.

Aggressive players can still take advantage of tight and passive opponents but must be careful to avoid tough spots. In the bubble phase, you must protect your stack while exploiting weak opponents.

10% Field Left – Aggressive Reopening (22bb CO RFI)

As only 10% of the field remains, players build their stacks for a final table run. Ranges get wider to pressure smaller stacks and gather chips, but ICM concerns stay the same.

• Raise Frequency:9%
• All-In Frequency:9%
• Fold Frequency:2%

Key Adjustments:

1. Wider Ranges

a) Inclusion of suited connectors (87s, T9s, 76s) and medium pocket pairs (66–88)

b) Marginal hands like A5s and K9s are raised instead of folded.

2. Postflop Control:

a) Players should move all-in with premium holdings such as (AKo, AQo, and JJ+) to avoid unnecessary risk.

3. Pressure Application:

Larger stacks exploit the ICM pressure on smaller stacks by stealing blinds and putting them in marginal spots.

At this point, players focus on accumulating chips and aim for bigger payouts to reach the final table.

Key Takeaway

Tournament poker strategy evolves dynamically:

• 50% Field Left: Aggressive, chip-building approach.
• 25% Field Left: Survival-focused, risk-averse play.
• Bubble Stage: Tight and selective ranges under ICM pressure.
• 10% Field Left: Aggression reopens to exploit opponents and build for the final table.

For long-term profits and tournament success, players should be able to adjust their strategy according to the different stages of the tournament.
