What Black actually plays here
Across 603 games from a Lichess-derived book of club play, Black scores 43.9% in this position. These are the replies people choose, and how each one works out.
| Reply | Games | Share | Black scores | Verdict |
|---|---|---|---|---|
| dxe4 | 443 | 73.5% | 46.4% | holds up |
| e6 | 94 | 15.6% | 36.7% | below the line |
| Nf6 | 35 | 5.8% | 37.1% | below the line |
"Below the line" means the reply scores at least three points worse than the position does overall. Replies played fewer than 25 times are left out: the sample is too small to read.
Is this costing you anything?
A table of averages cannot tell you whether you go wrong here — only your own games can. Opening Leak Lab reads your Chess.com or Lichess archive, finds the decisions you repeat, and checks each one against this book and a bundled Stockfish.
