How to Analyze Chess Games

Start with your own review

Before starting the engine, replay the game and mark moments where you had no plan or spent a lot of time. This separates real problems from the final result.

Then use Stockfish

Run analysis and inspect the largest evaluation drops. Do not memorize the first engine line; try to understand the idea behind the best move.

Finish with an exercise

Write down one or two conclusions and train a similar motif in puzzles or in the next training game.

Example post-game routine

First replay the game without the engine and mark places where you spent the most time or played from uncertainty. Then run analysis and check whether Stockfish identifies the same moments as critical.

If the mistake was tactical, name the motif: pin, fork, back-rank mate, overloaded defender, or discovered attack. If it was strategic, use a simple label: unsafe king, passive piece, no center, delayed castling, or a poor exchange plan.

What not to do

Do not copy the first engine line mindlessly. In short training, understanding the first mistake matters more than memorizing ten moves of a variation you may never see again.

Do not analyze every game for an hour. For most players, two concrete lessons and one exercise are better than a long list of mistakes without an action plan.
