What White actually plays here

Across 596 games from a Lichess-derived book of club play, White scores 47.3% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict
Nc3 344 57.7% 47.5% holds up
b3 95 15.9% 57.4% holds up
d4 59 9.9% 46.6% holds up
Nf3 30 5.0% 43.3% 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.
