# Chip stacks - what's important? BBs or relation to opponents'?

ICM throws up some strange results which it's hard for me to understand.

Situn 1 (3 handed) Blinds 50/100 : Hero is BU with 540, holding 10,3s; SB 9,560; BB has 9750. Push/fold?

Situn 2 (3 handed) Blinds 200/400 : Hero is BU with 1830, holding J,6o; SB 8,820; BB has 8750. Push/fold?

ICM says it's a fold in both cases but gives hero's range as 46.9% in the first case and 32.1% in second case.

My question is this: Hero is significantly short stacked in both cases. In scenario 1 he has 5.4 BB left; in scenario 2 he has 4.5 BB. So why would his range be tighter in the second case? Surely you would expect him to be pushing wider? Also, isn't a call by an opponent more likely in scenario 1, in which case you'd expect hero to be pushing tighter?

Or is it because, although Hero has less chips in scenario 2 when measured in BB, he has more chips (relatively) in comparison to his opponents? i.e. about 1:4.7 in second case but only 1:19 in the first case? If it is this, can someone explain - in layman's terms - why it makes a difference to the push range?

The only other difference I can see is the in situ 1, BB has the biggest stack whereas in situ 2, its SB. But it's pretty marginal and I can't see how it would make much difference to hero's range.

Help appreciated!

hi tim

I.C.M is not perfect !! always remember that.
in the first example T-3s....this is a fold,because you are so short stacked(5BB) and if you shoved either big stacks would call because they have such a huge calling range 40%+...EQUITY IS EVERYTHING .If you find your self in this position you need a strong hand to push against a big stack .In this example you will need a range of 10.7 %....66+,A9+,A-8s+,KQs
IF they are calling extremley loose you would need a 3.8% range....TT+,AK,AQs+

from 15 BB you should be pushing your stack,but you need to be able to judge your opponents calling ranges aswell as their pushing ranges .

what is my stack size (BB)
what is my opponents stack size(BB)
what is my position
what is the size of the blinds
