| Reply | Games | Share | Black scores | Verdict |

| Bb4 | 64 | 11.0% | 39.1% | below the line |
| c6 | 46 | 7.9% | 55.4% | holds up |
| Nbd7 | 42 | 7.2% | 47.6% | 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.
