This is a discussion on Can anyone explain EV Adjusted Winrate within the online poker forums, in the Tournament Poker section; Hi all,
Is there anyone who can explain the stat "EV Adjusted Winrate (bb/100)"
I am not sure what it is telling me... mine is 36.42
Basically EV Adjusted Winrate (bb / 100) is the amount of bb (big blinds) you win every 100 hands. And in this case it is Adjusted to EV. But it must take into account a high volume and not a small sample so that its value is close to reality.
It seem like, you intended to post this under "cash games", because measuring a winrate in BB / 100 is for cash games. In tournaments the most common measure is ROI, which mean Return On Investment. Anyways the EV adjusted winrate is the winrate adjusted for, how you ran in situations, where you were all-in before the river.
If for instance you got KK all in preflop against AA for 100BB and won, your actual result for that single hand is +100 BB (barring rake). However you only had around 20% equity, which mean your average expected result was -60BB. The EV adjusted winrate is simply the sum of all those expected results rather than the actual results, which were totally outside your control. The purpose is to get a somewhat more true picture of, how you actually performed, rather than just how lucky you got with the runouts, when no more decisions were to be made.
However its important to understand, that the result of these all-in before the river pots is only a small part of variance. You probably did not make any mistake getting it in with KK, so running KK into AA was just as unlucky, as cracking the AA was lucky. At the end of the day we can not pay any bills with "expected results", so I recommend not getting to hung up on them.
