| Reply | Games | Share | White scores | Verdict |
|---|---|---|---|---|
| Bd3 | 242 | 38.4% | 58.1% | holds up |
| c4 | 197 | 31.2% | 59.9% | holds up |
| Be2 | 75 | 11.9% | 51.3% | below the line |
| Ne5 | 32 | 5.1% | 51.6% | below the line |
| Nc3 | 26 | 4.1% | 73.1% | 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.
