    Default 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:

    Poker Hand #OM235475677: Omaha Pot Limit ($1/$2) - 2021/02/02 05:42:46
    Table 'PLOSilver11' 6-max Seat #5 is the button
    Seat 1: d98b5560 ($200 in chips)
    Seat 4: 9e53c3bb ($221.55 in chips)
    Seat 5: ef3c9d6b ($104 in chips)
    Seat 6: Hero ($93.25 in chips)
    Hero: posts small blind $1
    d98b5560: posts big blind $2
    *** HOLE CARDS ***
    Dealt to d98b5560
    Dealt to 9e53c3bb
    Dealt to ef3c9d6b
    Dealt to Hero [Ks Kd 3d 5c]
    9e53c3bb: calls $2
    ef3c9d6b: raises $7 to $9
    Hero: raises $22 to $31
    d98b5560: folds
    9e53c3bb: folds
    ef3c9d6b: raises $66 to $97
    Hero: calls $62.25 and is all-in
    Uncalled bet ($3.75) returned to ef3c9d6b
    ef3c9d6b: shows [9d Ad As 4s]
    Hero: shows [Ks Kd 3d 5c]
    *** FLOP *** [2d 2c Qs]
    ef3c9d6b: get an all-in insurance (premium ($0/$5/$0) for ($0/$60/$0) - (Mandatory/Main/Sub))
    *** TURN *** [2d 2c Qs] [Kh]
    ef3c9d6b: get main compensation of all-in insurance ($60)
    *** RIVER *** [2d 2c Qs Kh] [2s]
    9e53c3bb: shows [Tc Kc 2h Th] (Four Twos)
    *** SHOWDOWN ***
    Hero collected $184.5 from pot
    *** SUMMARY ***
    Total pot $190.5 | Rake $4 | Jackpot $2 | Bingo $0
    Board [2d 2c Qs Kh 2s]
    Seat 1: d98b5560 (big blind) folded before Flop
    Seat 4: 9e53c3bb folded before Flop
    Seat 5: ef3c9d6b (button) showed [9d Ad As 4s] and lost with Twos Full over Aces, AII Compensation ($60)
    Seat 6: Hero (small blind) showed [Ks Kd 3d 5c] and won ($184.5) with Kings Full over Twos

    Thanks

    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).
