What White actually plays here

Across 786 games from a Lichess-derived book of club play, White scores 49.7% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict

Nf3 172 21.9% 47.7% holds up
fxe5 32 4.1% 42.2% 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.
