What White actually plays here

Across 2,097 games from a Lichess-derived book of club play, White scores 58.1% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict
Nf3 1,915 91.3% 59.1% holds up
Bc4 143 6.8% 48.6% below the line
d4 27 1.3% 38.9% below the line

"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.
