HEM3 Not Calculating All-in EV for GGPoker Hands where Mucked Cards are Shown Down

Hi,

I've noticed that HEM3 is not calculating All-in Equity, even for preflop all-ins between two players, if a third player decides to "show" (a feature on GGPoker) their cards at showdown. This showing of cards gets included in the hand history and seems to result in HEM3 disregarding any all-in equity calculations. I've posted an example original format hand history that reproduces the issue below:

I'm having the same issue on Stars when a 3rd player is allin pre, and more money goes in post, it shows an allin adj. difference of 0.

This is completely different than the issue mentioned in the OP.

This is by design in HM3. HM3 uses the same equity code as PT4 now which is more accurate and less biased than the code we used for equity in HM2.

In a hand where a player is all-in but other players are not, net adjusted results are not calculated. When one player is all-in preflop and other players are not, then they usually have the option to act postflop and this means that sometimes one of them will fold. Having the option to fold* after another street is dealt means that in the long run there will be more strong hands which get to showdown and less weak hands. If we were to calculate net adjusted results in hands like this it would introduce a systematic bias (because there will be more known strong hands) so we exclude all hands like this from net adjusted calculations. You can read more about this here.

*Note: Attempting to calculate adjusted results when unknown but folded cards already called the all-in also introduce a bias into the results so HM3 does not make these calculations in any situation where a player calls the all-in and later folds (even if it's on the same street).

Oh, sorry I completely missed that going from HEM2 :) Thanks for letting me know!

No worries, it is big change from HM2 and gets asked about often.

You are very welcome. Good luck at the tables. If you have any further questions or problems do not hesitate to ask us.
