What Black actually plays here

Across 433 games from a Lichess-derived book of club play, Black scores 45.0% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare Black scoresVerdict
Bxb4 335 77.4% 44.0% holds up
Bb6 67 15.5% 55.2% holds up
Nxb4 25 5.8% 40.0% 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.
