Confused about this

Postby leviathan74 » Mon Feb 07, 2022 4:46 am

So I am reviewing my hand histories from today and I come across this hand:

PokerStars - 15/30 Ante 4 NL - Holdem - 7 players
Hand converted by PokerTracker 4: http://www.pokertracker.com

BTN: 48.5 BB
SB: 42.37 BB
BB: 91.7 BB
UTG: 49.77 BB
UTG+1: 57.23 BB
MP: 21.47 BB
Hero (CO): 42.87 BB

7 players post ante of 0.13 BB, SB posts SB 0.5 BB, BB posts BB 1 BB

Pre Flop: (pot: 2.43 BB) Hero has 9c 9d
UTG calls 1 BB, fold, MP raises to 21.33 BB and is all-in, Hero calls 21.33 BB, fold, fold, fold, UTG calls 20.33 BB

Flop : (66.43 BB, 3 players) 9s 4c Jc
UTG checks, Hero bets 21.4 BB and is all-in, UTG calls 21.4 BB

Turn : (109.23 BB, 3 players) 8c

River : (109.23 BB, 3 players) 6h

UTG shows 7c Tc (Flush, Jack High)

Main Pot [66.43 BB]: (Pre 23%, Flop 33%, Turn 76%)
Side Pot [42.8 BB]: (Pre 34%, Flop 34%, Turn 76%)

Hero shows 9c 9d (Three of a Kind, Nines)

Main Pot [66.43 BB]: (Pre 36%, Flop 65%, Turn 24%)
Side Pot [42.8 BB]: (Pre 66%, Flop 66%, Turn 24%)

MP shows Ad Qd (High Card, Ace)

Main Pot [66.43 BB]: (Pre 42%, Flop 2%, Turn 0%)

UTG wins 109.23 BB

As you can see, I got it in as a 66% favorite on the turn.

Pokertracker however has my all in adjusted BB as -42.87Bb which is the same as the amount I lost. This can't be right, can it?

In a hand like this where there was further action on another street after an all-in then PokerTracker 4 does not calculate adjusted equity as it introduces a bias in the results.

Ok, so I finally got around to reading this. I understand the logic of not trying to engage in EV calculations when some hold cards remain unknown. However, I notice the issue in situations where all the hole cards of people seeing the flop are known.

Personally, over the last few years, I have become obsessed with all-in EV BB/100 because although it's an imperfect metric - and I 'd be the first to tell you how liable it is to being biased in million other ways- it's the best metric of actual performance there is, especially for tourney players.

IMO, the way all in EV is calculated right now, when all the hole cards are knowm, better players who tend to get sucked out get to see their all-in EV be lower than it actually is. Also players who get it in on the flop as opposed to preflop get penalized more. The problem is if you are trying to keep track of your performance and you change your game in a way that favors getting it in more in postflop rather than preflop, then you might see your BB/100 get worse even though your game has improved. You then run the risk of drawing the wrong conclusion.

Ultimately, I understand this isn't the biggest issue in the world, but I would appreciate it if at some point you revisited it and at least change the way the EV calculation is done in these spots.
