How do you analyze your own chess games?
Replay the game without an engine first and mark the two or three moments where you were unsure or the game turned. Write down what you were thinking, find your own better move, then check with the engine and ask why its move works. Finally, label each mistake and look for the patterns that repeat across many games.

Replay the game before you ask an engine
Open the game and play through it yourself, with the engine turned off. Stop at the two or three moments where you hesitated, where the position changed, or where the result slipped away. Mark those moments. This first pass is about remembering your decision, not about collecting a list of mistakes from a computer.
Write down what you were thinking
At each marked moment, write a sentence or two: what you wanted, what you were afraid of, and why you chose the move you played. If you cannot remember, write that down too. A review that only says the move was wrong never shows you the habit that produced it.
Find your own better move, then check it
Before you turn the engine on, pick a move you like better and say why, in plain language. It might save a piece, stop a threat, finish development, or keep your king safe. Then look at the engine's move and ask why that move works: what it defends, what it attacks, or what it prevents. Copying a line you do not understand will not change the next game.
Give the mistake a label
Name each mistake in words you can spot next time. Hung piece, missed threat, impulse capture, clock panic, a mix-up in the opening, or a plan that ignored your opponent's last move. A short label turns one bad game into something you can watch for.
Look for the label that repeats
One game is a story. A run of games is a habit. After several reviews, group the labels. The one that keeps showing up is the one to work on next. Take those positions and practice them: see the board, find the better move, and repeat until the check is automatic. Then play again and see whether that label still appears.
FAQ
Should I analyze wins, or only losses?
Review wins as well. A win still has moments where you were unsure, and the same habit can lose the next game. Mark those moments the same way.
How long should one review take?
Long enough to mark two or three moments, write what you thought, and name a better move. A short honest review of one game teaches more than skimming ten games.
When should I turn the engine on?
Last. Your notes tell you what you were thinking. The engine tells you whether a better move was there, and it gives you a reason to study. If you start with the engine, you get a move you never chose.
What do I do with the mistakes I find?
Label them and watch for the same label in the next games you play. When a label repeats, practice that kind of position on purpose instead of collecting more one-off notes.
