What White actually plays here

Across 819 games from a Lichess-derived book of club play, White scores 49.5% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict
Nc3 292 35.7% 46.6% holds up
c4 230 28.1% 50.4% holds up
d4 108 13.2% 55.6% holds up
Nf3 89 10.9% 60.7% holds up
Bc4 42 5.1% 42.9% 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.
