Nine players, the payouts of a normal final table, and everyone short.
Here is what changes at a nine-handed final table when all players have 10 big blinds and the payouts are 28, 19, 13, 10, 8, 7, 6, 5 and 4 percent of the prize pool. The numbers are the share of hands the first player to act shoves, folded to him:
| Seat | Chip EV shove | ICM shove |
|---|---|---|
| Lojack | 23% | 29% |
| Hijack | 28% | 32% |
| Cutoff | 33% | 44% |
| Button | 43% | 61% |
| Small blind | 72% | 98% |
Every seat shoves more under ICM than in chip EV, and the gap grows toward the blinds: the small blind shoves 98% of hands (72% in chip EV).
When the cutoff shoves, the three players behind him decide:
| Caller | Chip EV call | ICM call |
|---|---|---|
| Button | 15% | 7% |
| Small blind | 22% | 8% |
| Big blind | 29% | 10% |
Calling ranges are more than halved. A player who calls off at a final table risks several places in the payout ladder for the chance to win more chips that are worth less than they look.
They come from our own push/fold model of the whole hand. Every player, in turn, can fold, go all-in or call an all-in. The payouts use the Malmuth-Harville ICM, and the ranges are found by repeated best responses until they settle (they move by about a percentage point between runs; a second, independent solver agrees with the chip EV numbers to within about a point and a half). The blinds are 0.5 and 1 BB and the antes total 1 BB. Stacks are before posting. There is no postflop play, because an all-in and a call run to showdown. It is an approximation of the real game, and ICM itself ignores skill and position after the flop. It is a map for study, not an exact solution.
One short lesson a day, each with a worked example in exact numbers: chips vs. money, the bubble factor, who feels the pressure, payout structures, satellites. No account needed.
First in, yes, when stacks are similar and short. In our model every seat shoves more under ICM than in chip EV with nine players on 10 BB.
Yes. In the cutoff shove example the callers continue with 7% to 10% of hands against 15% to 29% in chip EV.
Yes, antes total 1 BB, blinds are 0.5 and 1 BB.
