What Black actually plays here

Across 760 games from a Lichess-derived book of club play, Black scores 48.2% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare Black scoresVerdict
O-O 600 78.9% 49.6% holds up
Bg4 67 8.8% 45.5% holds up
Nbd7 36 4.7% 48.6% 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.
