| f3 | 32 | 3.9% | 46.9% | below the line |
| Nc3 | 28 | 3.4% | 53.6% | holds up |

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.
