What Black actually plays here

Across 546 games from a Lichess-derived book of club play, Black scores 34.2% in this position. These are the replies people choose, and how each one works out.

b5 143 26.2% 33.9% holds up
e6 142 26.0% 32.7% holds up
Nc6 77 14.1% 40.9% holds up
Nf6 61 11.2% 27.9% below the line
e5 51 9.3% 30.4% 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.
