yeah im sorry. one of the screenshots (7way is wrong). should be:

CO shoves 25%
B: 5.4 (4way is 13% tighter)
SB: 6.6 (4way is 11% tigher)
BB:8.0 (4way is 11% tighter)

but again this is with increased antes for 4way so not entirely accurate. best to remove antes and compare like i did a few posts back.

Strange things happen in ICM-land.

Ive just tried out an example where i compared two 7-handed spots. The first spot with a normal 180man payout distribution, but in the second one i artificially upped the 6th prize payout. When you now look at the call range of the bb vs a button shove, you see the bb calls alot tighter with the increased payjump. bb-call= 9% vs 7%.

But if you compare a 7handed situation with a 3handed situation. Where the payjump difference is even larger, the bb calls a lot looser. (10.7% vs 9%) 3way.

Futhermore i find it mighty strange, that when you compare 4-way vs 7-way and the CO shoves. The button calls a lot tighter 4-way but the BB calls tighter 7-way.

EDIT: i might have found the answer why the B calls tighter 4-way then 7-way. Maybe because when he folds, the times that SB clash with BB is super duper good for him (the is less of a factor 7way cause the payjump is lower). So folding 4way is better then folding 7way on the button.

Maybe because the payout structure is a lot more top heavy 4-way than im comparission to 7-way?

Cuz the hands value decreases dramatically the shorter the table gets and is not the same when the CO is the one open shoving in a 7-handed or in a 4-handed table and we´re on the BU than the BU open shoving and we´re in the BB, we´re getting a much better price to call a much wider/weaker range than if we were in the BU facing a CO open shove imo

Top heavy would suggest looser call ranges not tighter.

1. Why is it not the same when the co shoves 4way vs 7way when you remove the antes? except for the obv payjump differences.

2. I did not compare a bb call range with a b call range. Dont know what gave you that idea.

I had a look at the 4-handed vs 7-handed jams. It's true that some of the ranges for jams further out look strange. I think it might be due to how the equity of folding blinds affects other's equity (i.e. when one player out of 7 has dropped a tenth of his stack by folding the BB this is less important than when one player out of 4 has done this).

SB vs BB without antes however is the one that most closely corresponds to the way the avg bubble factors are calculated as there is no dead money from other players and also where we have almost identical ranges whether we are 7-handed or 4-handed - this is what we would expect, while the absolute highest value is at 7-handed, the average bubble factors are all very very close throughout the final table).

Another possible explanation (and also why the effect isn't visible with SB vs BB is the same) could be due to the possibliity of 3-way pots. Bubble factors assume 2-way pots but out "3-way bubble factors" - in the case of avg bubble factors where we can see a 2 people eliminated at the same time it might be different - or alternatively the software might not correctly handle the rare case of two players with identical stacks eliminated on the same hand.
