- Chess players improving without a coach
- Worth noticing
- It measures opening habits and recurring mistakes across up to 2,000 games, rather than teaching a generic repertoire.
Field notes
The homepage frames improvement as pattern recognition across a player’s own history rather than memorizing someone else’s repertoire. Its examples include a Scandinavian Defense measured across 532 games and interactive positions where the opponent’s last move is already played. The site also limits its stated target audience to players up to about 2300 Elo, acknowledging that automated explanations may be less useful for stronger players.
