# Thread: mistake of calculation \$EV in preflop all-in

1. ## mistake of calculation \$EV in preflop all-in

hello!

It's SnG \$6.50 FR on FTP.
Have a little problem.
===================================
Hold'Em Manager Poker Software - Tracking and Analysis Poker Software
NL Holdem \$120(BB) Replayer Game#30519495595

SB (\$2,400)
BB (\$6,450)
CO (\$1,620)
HERO (\$3,030)

SB posts (SB) \$60
BB posts (BB) \$120

fold,
HERO raises to \$300
fold,
BB raises to \$6,450 (AI)
HERO calls \$2,730 (AI)
FLOP (\$6,120) 3c Jh 7h
TURN (\$6,120) 3c Jh 7h 4h
RIVER (\$6,120) 3c Jh 7h 4h Kh
(Pre 50%, Flop 50.0%, Turn 50.0%)

BB shows Kd Ac
(Pre 50%, Flop 50.0%, Turn 50.0%)

HERO wins \$3,060
BB wins \$3,060
===================================

It's situation 50.4%/49.6%, but only in 2.9% one of us won all pot.
HM (v 1.11.06d) calculate my \$EV diff=-\$4.29(!?!). opponent with AcKd have \$EV diff=-\$0.56. opponents who dont play this hand have \$EV diff=+\$2.07 and +\$2.78.
Why? IMHO it's bug. Please fix it.

2. We had a EV bug 1.11.05 - 1.11.05d (fixed in 1.11.05e and also didn't occur in earlier versions)
create a new database and reimport the hands.

3. thanks, it worked.

Question.
Can you make in HM calculating values \$EV for each street separately? It about hands without preflop all-in.

4. EV-by-street for SNGs?

We considered EV-by-street for cashgames, but opted against it.
Read: EV in not all in situations

For SNGs a similar situation would happen where the EV by street often cannot be calculated, leading to inaccurate longterm results if you'd only calculate it for the hands where it is possible.

Since many players are still interested in EV-by-street and other EV methods (HoldemManager only uses All-in EV) take a look at:

Yes, I meant SnGs.

Indeed, if hero going all-in on preflop, but other opponents (2 +) is not, and one (or more) of them didn't comes to showdown - calculate \$ EV diff for hero is not possible.
But if all other opponents came to showdown - \$ EV diff can be calculated.
If it is realized in SnGs - it will be great.

PS: Sorry for long discussion - me a little sad. I thought my new license SnG Wiz app covers both my HM (my desktop computer & notebook), but it is not.
