How to Analyze Your Own Chess Games

Why review your own games at all

You can study openings and watch grandmaster videos for years and still lose the same way every week. The fastest feedback loop in chess is your own games, because they contain your actual mistakes — not hypothetical ones. Reviewing them is how you find the patterns that are specifically costing you rating.

Do your own review first, then check the engine

Before you turn on an engine, go through the game yourself and note the moments that felt uncomfortable: where you were unsure, where the position changed character, where you started to drift. This is where the learning happens — the engine should confirm or correct your judgment, not replace it.

Then run an engine over the game. You are looking for two things:

• Tactical blunders: moves where your winning chances dropped sharply in a single move. These are usually concrete — a hung piece, a missed threat, a miscalculated trade.
• Turning points: the handful of moments that actually decided the result.

Focus on blunders, not every imperfection

An engine will flag dozens of tiny inaccuracies. Ignore most of them. The difference between the second-best and third-best move almost never decides a club game; the blunders do. Filter ruthlessly: if a move did not meaningfully change who was winning, it is not worth your training time.

A good rule of thumb is to train only moves that cost roughly 15% or more of your winning chances. That threshold separates “decided the game” from “engine noise.”

Turn findings into training, not just notes

The mistake most players make is to analyze a game, nod, and move on. You will forget the lesson within days. To actually improve, the positions where you blundered need to come back — days later, from the other side of the board — until the right move is automatic. That is spaced repetition, and it is the difference between reviewing games and improving from them.

Make it automatic

Doing all of this by hand — exporting games, running an engine, extracting positions, scheduling reviews — is a lot of work, which is why most people skip it. PatternChess does it for you: connect a Chess.com or Lichess account, and it imports your games, finds your blunders with Stockfish, and schedules them for spaced-repetition drilling. Try it free.
