What Black actually plays here
Across 591 games from a Lichess-derived book of club play, Black scores 61.5% in this position. These are the replies people choose, and how each one works out.
| Reply | Games | Share | Black scores | Verdict |
|---|---|---|---|---|
| e5 | 233 | 39.4% | 63.1% | holds up |
| d5 | 140 | 23.7% | 58.6% | holds up |
| c5 | 43 | 7.3% | 60.5% | holds up |
| e6 | 32 | 5.4% | 56.2% | below the line |
| h5 | 27 | 4.6% | 64.8% | 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.
