How to Analyze Your Chess Games: A Step-by-Step Guide
Playing without analysis is like practicing without feedback. Here's how to review your games properly and actually learn from every mistake.

You just lost a game. You feel frustrated, maybe a little confused about where it all went wrong. So you close the tab and start a new game. Sound familiar?
This is the single biggest mistake improving players make: playing without analyzing. Every game you play contains lessons — missed tactics, opening inaccuracies, endgame mistakes — but those lessons are invisible unless you review with an engine.
Why Game Analysis Matters
Think of analysis as a feedback loop. Without it, you're practicing in the dark:
- You don't know which moves were good and which were bad
- You repeat the same mistakes because you're not aware of them
- You can't identify patterns in your play (always blundering in time pressure, always misplaying rook endgames, etc.)
With analysis, every game — win or loss — becomes a lesson.
Step-by-Step: How to Analyze a Game
Step 1 — Import Your Game
Head to our analysis tool and import your game. You can paste a PGN directly or import from Lichess in one click. The engine will evaluate every move automatically.
Step 2 — Check the Opening
Look at the first 10-15 moves. The engine evaluation should stay close to 0.0 (equal). If there's a sudden spike, that's where someone made an opening mistake.
Ask yourself:
- Did I follow my opening preparation?
- Where did I deviate — and was it a good or bad decision?
- Did my opponent play something I didn't expect? How should I respond next time?
If you consistently lose out of the opening, it's a sign you need to study your repertoire more deeply. Check our openings library for the lines you play.
Step 3 — Find the Critical Moments
Scan through the game and look for evaluation swings — moments where the advantage shifted significantly. These are your critical moments. For each one:
- What did you play, and what should you have played?
- Was it a tactical miss (you didn't see a combination) or a strategic error (wrong plan)?
- Could you have found the right move with more careful calculation?
Step 4 — Categorize Your Mistakes
After reviewing, group your mistakes into categories:
- Tactical blunders — missed forks, pins, hanging pieces
- Opening errors — deviating from theory in a bad way
- Strategic mistakes — wrong plan, bad piece placement, poor pawn structure decisions
- Endgame errors — failed to convert an advantage, wrong technique
- Time trouble mistakes — blunders made under time pressure
Over 10-20 analyzed games, you'll see clear patterns. Maybe 80% of your losses come from tactical blunders in the middlegame. Now you know exactly what to train.
Step 5 — Write Down One Takeaway
Don't try to fix everything at once. After each analysis session, write down one specific thing to work on:
- "I keep missing knight forks — do 10 fork puzzles today"
- "I don't know what to do after 1.d4 d5 2.c4 dxc4 — study the QGA"
- "I lost a winning rook endgame — review king activity in rook endings"
That one takeaway becomes your training focus until the next game.
How Often Should You Analyze?
Ideally, every serious game — meaning every game where you had time to think. Blitz games are less useful for deep analysis, but even there, a quick 2-minute scan for blunders is valuable.
The ratio that works best: for every 3 games you play, analyze at least 1 in depth. Quality of analysis beats quantity of games, every time.
