What White actually plays here

Across 923 games from a Lichess-derived book of club play, White scores 51.6% in this position. These are the replies people choose, and how each one works out.

ReplyGamesShare White scoresVerdict
dxe5 595 64.5% 49.9% holds up
d5 166 18.0% 59.3% holds up
e3 66 7.2% 62.1% holds up
c4 28 3.0% 55.4% 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.
