    Default Not calculating EV when 3way all in

    If 1 player is in preflop before the flop and then I get in with the other player post flop, it doesn't calculate the EV.

    Anyway to fix this?

    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).

    They could calculate the all-in EV of the last side pot.

    That would also introduce a bias so we do not calculate the All-In Adj value for either pot.
