Across 1,885 games from a Lichess-derived book of club play, Black scores 54.5% in this position. These are the replies people choose, and how each one works out.
| Reply | Games | Share | Black scores | Verdict |
|---|---|---|---|---|
| d5 | 1,711 | 90.8% | 54.9% | holds up |
| e6 | 96 | 5.1% | 50.5% | below the line |
| d6 | 26 | 1.4% | 57.7% | holds up |
"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.
