progressICM three-handed with 50/30/20 payouts
Three players, every place pays.
This page works through a three-handed end game. The numbers are exact results of the ICM model (the probability of finishing first is proportional to the stack, then the same rule for the next place), not estimates.
The payouts
Share of the prize pool by finishing place:
| 1st | 2nd | 3rd |
|---|---|---|
| 50% | 30% | 20% |
Equity of every stack
Example stacks, total 10000 chips:
| Seat | Chips | Share of chips | ICM equity | Equity minus chip share (points) |
|---|---|---|---|---|
| 1 | 5000 | 50% | 38.4% | -11.6 |
| 2 | 3000 | 30% | 32.8% | +2.8 |
| 3 | 2000 | 20% | 28.9% | +8.9 |
The biggest stack is worth 38.4% of the prize pool while holding 50% of the chips. The smallest stack is worth 28.9% and holds 20%.
Bubble factors
Bubble factor of the row player when all-in against the column player, for the first 3 seats:
| Hero \ Villain | Seat 1 | Seat 2 | Seat 3 |
|---|---|---|---|
| Seat 1 (5000) | — | 1.17 | 1.09 |
| Seat 2 (3000) | 1.55 | — | 1.11 |
| Seat 3 (2000) | 1.35 | 1.17 | — |
Across all pairs the highest bubble factor in this example is 1.55 (seat 2 with 3000 chips all-in against seat 1 with 5000), and the lowest is 1.09 (seat 1 against seat 3). A seat with bubble factor 1.55 needs about 61% equity to call an all-in that offers even odds.
What it means for your play
- Calls need more equity than pot odds. The highest bubble factor above is the price of the riskiest call.
- The chip leader can pressure medium stacks, since the cost for them to call is high.
- Short stacks are worth more than their chips and should avoid needless gambles unless the blinds force them.
- Change the payouts in the calculator to see how the same stacks are worth different amounts in different structures.
