Field notes
The proposed diagnosis sorts a player’s games by colour, time control, opening, and game length before identifying a costly weakness. Its Ideas Trainer is described as quizzing players on plans and explaining them. The page says imported games and the trainer are live, but places the fuller diagnosis engine, verified points, and ratings on the server rather than in the current front end.
