All-in EV

What your all-ins were worth on average, counting each called all-in at your equity instead of its result.

What it means
Once the chips are all in, your decisions are over and only the cards are left. All-in EV replaces the result of each called all-in with what it was worth, so luck drops out of your results.
How it is calculated
For a called all-in for S big blinds with equity e, the all-in EV is S × (2e − 1). The equity comes from the engine, from your two cards against the opponent's two. Hands that end in a fold count at their actual result.
Worked example
You shove 10bb with 80% equity and lose. Your chips go down 10bb, but your all-in EV goes up 10 × (2 × 0.8 − 1) = 6bb. The 16bb gap is bad luck, not a bad decision.
Why it matters
Short matches are mostly variance. Comparing chips with all-in EV shows whether a good or bad session came from your play or from the deck.
