    Yes, all-in EV is not calculated in multiway pots.

    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 - https://www.pokertracker.com/blog/20...-all-in-equity

    *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).

    I prefer to see the all-in EV for the two remaining players when they go all-in later, and there is no way that can be made inaccurate, as having an option to fold isn't a consideration when all players are all-in. HM2 gives the more correct overall stats for all-ins here, HM3 just when it doesn't include the 3rd players who is all-in earlier. I would put both stats in HM3, as now one needs to check the all-in stats with HM2. Posted this bug whn I saw it in party fast PLO; not sure it posted, but I saw this thread and opted to post about it here also.

    HM2's EV formula led to a bias that made the HM2 Equity stats less accurate than PT4/HM3. We have no plans to go back to a less accurate all-in equity formula.
