SNG EV diff Problem

[SibiuStar]

hi.there is a problem w/ the EV Diff for STTs.i sent it to your support something like 2months ago but i got a standard reply that sent me to the EV calculation video.

i'll put hear 3 hands w/ +ev decisions that are marked as -ev :

We had a big EV bug in 1.11.05-1.11.05d.

Update to http://www.holdemmanager.com/Downloa...1.11.05e-1.exe
Create a new database--> reimport all your hands.

However I think most of your examples are not effected by the EV bug.
77 vs 66 (77 = 75% fav)
KK vs 77 (KK = 80% fav)
KK vs straight-draw (KK = 66% fav)

It's clear it's a +EV decision to end up allin with the favorite hand.
But since you actually win the hand it will always result in a negative EV Diff. (losing the hand would result in an even bigger positive EV Diff)

Why?
Suppose startstack 1000 chips. 10 players. Buyin $10.
There are 4 players left. Top 3 in the money
Player A - 3000 chips - KK
Player B - 3500 chips - 77
Player C - 2000 chips
Player D - 1500 chips


Two players A & B go allin with KK vs 77.
Now three scenario's can happen:
-1 (80.30%) KK wins
-2 (19.35%) 77 wins
-3 (0.35%) the hand results in a splitpot!

If -1 occurs, player A will have a negative EV Diff for that hand, based on the independent chip model and the fact that he is eliminated 19.35% of the time here in 4th place.
If -2 occurs, player B will have a negative EV Diff, and player A will have a huge positive EV Diff (since 80.3% of the time he would end up in the money with a big chiplead)

If -3 (or -2!) occurs it's a disaster for player C & D not even involved in the hand!
And they will get a positive EV Diff, since 19.35% player C & D would automatically be in the money. And if player A wins, player D will no longer be the shortstack.

etc.


So it's irrelevant someone is a 80% favorite (and ends up winning the hand).
Other elements: based on stacksizes, the chance to lose--> and what exactly happens if you lose all matter and affect the EV Diff.
