What Black actually plays here

Across 505 games from a Lichess-derived book of club play, Black scores 49.7% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare Black scoresVerdict
e4 207 41.0% 53.9% holds up
exf4 156 30.9% 46.5% below the line
Qxd5 102 20.2% 41.2% below the line
c6 28 5.5% 60.7% holds up

"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.
