What Black actually plays here

Across 601 games from a Lichess-derived book of club play, Black scores 46.3% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare Black scoresVerdict
Nf6 334 55.6% 47.2% holds up
d6 149 24.8% 41.6% below the line
h6 54 9.0% 49.1% holds up
a6 28 4.7% 39.3% 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.
