If you are referring to the ICM Trainer, then it is the difference between your equity if you shove and the equity you have left if you fold.

In this context, "Equity" refers to your expected share of the prize pool, not you equity in a particular pot.

If the difference is > 0 then you should shove.
If the difference is < 0 then you should fold.

There is also a factor called "edge" -- if you set the edge to 0.2 for example, then the trainer doesn't recommend a push unless Eq Diff > 0.2

But yes, I do not refer to ICM but to Equilab/Equity trainer. Hope you can explain that also.

Hi, I just had a look at the Equilab Equity trainer.

In Question 1 the flop given was Ts9sJs
Hero's hand is given as Qc9h

I slid the Estimated Equity slider to 50%, and clicked "Result"

The Actual Equity was 46.1
My guess minus actual Equity is the "Absolute difference" -- in this case 3.9%
The relative difference is a measure of how bad my guess was.

In the case (absolute difference)/(actual equity) is 3.9/46.1 which is 0.085, or 8.5 %

Hope that helps,

Thank you very much!

Its good to know what "Relative difference" means. Although I can imagine nobody who's interested in knowing that relation it expresses :-P.

Best luck!

It is just a measure of how good your estimate is.

The lower the number, the better your guess is.

I'm just glad you asked, because I had never gone in there before, and it looks like it could be useful.

It is a really nice tool! Specially i like this "take selection to main window" - button.

But I think you agree, that if i miss 5% then I missed 5% and it doesn't matter if Equiti was 15% or 90%. I mean the consequences of my mistake will not be bigger if i misscalculate my EQ on flop where I have only 15% EQ

NO, I'M WRONG!

If i risk 10\$ in order to win 20\$ i need 50% equiti and if i actually have 45% then my EV will be -1\$

If i risk 10\$ in order to win 100\$ i need 10% if i actually have 5% then my EV will be -4,5\$

So indeed, this relative difference has some point.
