Your first analysis should preserve what you understood during play. An engine is more useful after you have recorded your decisions and uncertainties.
What to do
Replay the game without evaluation, mark critical moments and write candidate alternatives. Then use analysis tools to check those specific questions and the opponent’s stronger replies.
A mistake to avoid
Do not replace your notes with a list of engine labels. Knowing that a move was inaccurate does not explain how to avoid the same decision error.
A detail worth checking
Preserve uncertainty in the notes. A question written honestly before engine review reveals more about your thinking than an explanation rewritten afterward as if the correct answer had been obvious during play.
Try this practical check
Choose one game and summarize three decisions in your own words. After checking them, write one practical lesson you can recognize in a future game.
