What Black actually plays here

Across 434 games from a Lichess-derived book of club play, Black scores 47.2% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare Black scoresVerdict
e4 215 49.5% 52.8% holds up
exd4 119 27.4% 40.8% below the line
d6 45 10.4% 46.7% holds up
Nc6 37 8.5% 45.9% 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.
