How to Analyze Chess Games Using PGN Files (Complete Guide)
Introduction
If you’ve ever looked into improving your chess, you’ve probably come across the term PGN.
But what exactly is it?
And more importantly — how can you use it to improve your game?
A PGN (Portable Game Notation) file contains the complete record of a chess game. It’s the standard format used by platforms like Chess.com and Lichess.
When combined with a PGN analyzer, it becomes one of the most powerful tools for improvement.
In this guide, you’ll learn:
- What PGN is
- How to analyze PGN files
- What to look for during analysis
- How to improve faster using PGN
What Is a PGN File?
A PGN file is simply a text format that records:
- Moves played
- Game metadata (players, result, date)
- Annotations (optional)
Example: 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6
This format allows you to:
- Save games
- Share them
- Analyze them using tools
Why Use a PGN Analyzer?
A PGN analyzer allows you to:
- Detect mistakes automatically
- Find better moves
- Understand key turning points
Instead of guessing what went wrong, you get objective feedback.
How to Analyze a PGN File (Step-by-Step)
Step 1: Copy Your PGN
From Chess.com or Lichess:
- Open your game
- Click “Download PGN” or “Copy PGN”
Step 2: Paste into a PGN Analyzer
Use a tool like ChessPilot:
- Paste your PGN
- Click analyze
Step 3: Review the Analysis
Focus on:
- Blunders
- Missed opportunities
- Evaluation swings
What to Look for in PGN Analysis
1. Blunders
These are major mistakes that change the evaluation drastically.
Fixing blunders alone can boost your rating significantly.
2. Inaccuracies
Smaller mistakes that gradually worsen your position.
3. Missed Tactics
Opportunities where you could have gained advantage.
4. Opening Errors
Mistakes in the early phase of the game. (Try our Opening Explorer to fix these.)
Common Mistakes When Using PGN Analyzers
❌ Only looking at best moves
Understanding is more important than memorizing.
❌ Skipping analysis
Many players collect PGNs but never analyze them.
❌ Ignoring patterns
Repeated mistakes are your biggest weakness.
