How to Analyze Your Chess Games

Self-analysis is irreplaceable because:

1. Your games contain your specific weaknesses, not generic ones from a textbook.
2. You remember what you were thinking during the game, giving you insight into your thought process.
3. The emotional connection to your own games makes the lessons stick.
4. Patterns from your games will recur, fixing them pays immediate dividends. As Botvinnik said: "Analyze your own games, study your own mistakes."

Before opening Stockfish, go through the game yourself.

1. Identify the key moments, where did the evaluation shift?
2. At each critical point, ask: what were my candidate moves? Did I consider the right ones?
3. Write down your thoughts: why did you choose each move?
4. Mark moves you were unsure about. This first pass reveals your thinking process, the engine will only tell you the result.

Now use an engine, but carefully.

1. Don't just check who was winning, understand why the engine prefers a different move.
2. Focus on moves where the evaluation changed significantly (±0.5 or more).
3. For each mistake, understand the pattern: was it a tactical oversight, a strategic error, or a psychological lapse?
4. Don't obsess over tiny engine differences (±0.1), focus on the big swings.

1. Write down 2-3 concrete lessons from each game.
2. Categorise each lesson: opening, middlegame, endgame, or psychology.
3. Track recurring mistakes, if you keep missing the same tactical pattern, add it to your training.
4. Create a personal "mistake database" and review it monthly. Use the analysis board for detailed study. See also: Science of Chess Improvement.
