What White actually plays here

Across 657 games from a Lichess-derived book of club play, White scores 55.7% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict
e3 360 54.8% 59.4% holds up
Nf3 183 27.9% 53.8% holds up
Bxf6 49 7.5% 46.9% below the line
cxd5 47 7.2% 44.7% 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.
