# What are the most important stack distributions to understand for final table ICM

For instance with 4 players left - lets assume we can have any combination of very short (5BB), short (15BB) medium (25BB) and big (45BB).

If we take all combinations with replacement, then group by number of unique stack sizes, we get the following. However it is unclear which ones are most important. I'll put a * next to the ones I think might be important.

1:
(5, 5, 5, 5), *
(15, 15, 15, 15),
(25, 25, 25, 25),
(45, 45, 45, 45)

2:
(5, 5, 5, 15),
(5, 5, 5, 25), *
(5, 5, 5, 45),
(5, 5, 15, 15), *
(5, 5, 25, 25),
(5, 5, 45, 45),
(5, 15, 15, 15), *
(5, 25, 25, 25),
(5, 45, 45, 45),
(15, 15, 15, 25),
(15, 15, 15, 45),
(15, 15, 25, 25),
(15, 15, 45, 45),
(15, 25, 25, 25),
(15, 45, 45, 45),
(25, 25, 25, 45),
(25, 25, 45, 45),
(25, 45, 45, 45)],
3:
(5, 5, 15, 25), *
(5, 5, 15, 45),
(5, 5, 25, 45),
(5, 15, 15, 25), *
(5, 15, 15, 45),
(5, 15, 25, 25), *
(5, 15, 45, 45),
(5, 25, 25, 45),
(5, 25, 45, 45),
(15, 15, 25, 45),
(15, 25, 25, 45),
(15, 25, 45, 45),
4:
(5, 15, 25, 45) *

For some of those the seating order matters.

Would appreciate ideas on which stack distributions you think are most important to do ICM study with.

Hi ! I think that with 4 players remaining or even at the final table, it is very difficult to establish the movements that we must make by ICM, today there are numerous totally free ICM calculators, even to install on our mobile devices. To get any of them, just put in Google "free ICM poker calculator". In this way you will simplify your work much more at that time since you will seldom face the same situation in relation to the stacks and the amount of money you play for. I hope this helps. Cheers!
