Chess Diagnostics is much more than a simple chess board – it is a full-featured chess game analyzer that detects recurring patterns across dozens of your games:

• Game Phases (PRO): Where do you make the most mistakes – in the opening, middlegame, or endgame?
• Time Pressure: Does your accuracy drop when the clock is ticking?
• Tactical Blunders: Which chess puzzles and tactics motifs (forks, pins, skewers) do you regularly overlook?
• Progress: How is your accuracy and Elo trending over time?

Blunders, mistakes, and inaccuracies are displayed in clean, visual charts.

── TARGETED TRAINING WITH YOUR CHESS COACH APP ──

Based on your actual weaknesses, this chess coach app recommends customized Lichess studies (PRO) and targeted chess puzzles and tactics. No generic lessons – only what your chess game actually needs to grow. Work through interactive chapters directly inside the app, with integrated progress tracking.

── GAME REPLAY & BLUNDER COACHING ──
