| Reply | Games | Share | White scores | Verdict |
|---|---|---|---|---|
| Nxd4 | 1,300 | 90.5% | 50.6% | holds up |
| Qxd4 | 86 | 6.0% | 48.3% | holds up |
| c3 | 30 | 2.1% | 68.3% | 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.
