Scout
Prepare against any chess.com or lichess player: weaknesses, repeated lines, psychology, and a pre-game checklist built from their recent games.
Every stat is confidence-gated. Nothing is shown until the sample is big enough to trust.
New: Comparative ScoutSave your own scout profile once, then get opening advice built from lines you already play — not suggestions you have never prepared.
Compare with my repertoireWhat a scout report gives you
- Opening weaknesses by colour, with loss rates from their real games
- The exact lines they repeat, and where those lines go wrong
- Tilt patterns: how they play right after a loss
- A pre-game checklist and a downloadable PDF report
