In multiway allin preflop pots in cash-games with 2 villains and both checking it down, the equity is always set on 0.

Also if you get KK allin preflop vs QQ and JJ.


And when villain1 with QQ hits Qxx flop and bets and villain2 folds your equity is given as if you got it allin on the flop.


Why is this?

2 things after reading other thread:

1]

If both villains just check all streets you can give Hero his preflop equity instead of zero ev you get right now, because all 3 preflop hands are known because of showdown.

2]

If villain 2 folds flop after villain 1 bets his set of Queens and you have Aces.

Why give Hero 10% equity then?

Because that will never equal out because villains very rarely bluff when there is a sidepot.

Maybe make the hand zero ev for Hero?

We do the calculations from when the action stops, not from when you were all in. If we did it any other way, it would be biased because you would tend to see hands that connected well with the board at showdown, whereas hands that miss are more likely to fold.

Ok, and what about if:

Hero goes allin preflop.

Villain 1 and villain 2 call.

And both villains check all streets.


Why isnt Hero's equity his actual preflop equity?

There is no way to know your all-in % from an earlier street since some players in the hand at that point did not show their cards.

Huh?

Their hands are shown to us at showdown.


One final try: :)

preflop: Button raises 3bb, sb calls 3bb, hero shoves 30bb and is allin, button calls 27bb, sb calls 27bb

flop: sb checks, button checks

turn: sb checks, button checks

river: sb checks, button checks

sb shows 66, button shows 77, Hero shows AA.


Now in HEM Hero's equity is set to o (zero).


In my opinion Hero should be given his actual preflop equity.


I dont understand why not.

......

But you were the only one that was all-in. You can not have an All-In Expected Value (Equity) if there is no one else all-in with you (and showing their hole cards), so your equity is 0. The formula we use will only calculate All-In Equity. You have to have 2 known, all-in hands, to be able to calculate your equity against the other. If there is no other all-in hand, you can not calculate the equity. I am no expert on this subject, but this is a relatively fundamental part of the definition of 'All-In Expected Value'.
