What is PGN in Chess?
**PGN: The Universal Language in Chess
If you’ve spent any time playing chess online or analyzing your own games, chances are you’ve come across something called a PGN file.
Maybe you copied it from Lichess. Maybe a coach asked you to send it over. Maybe you saw a wall of brackets and moves and thought, “Looks important… no idea what this means.”
No worries—we’ve got you covered.
In this guide, you’ll learn what PGN is, why it’s useful, and how to start using it to level up your chess!
What is PGN?
PGN stands for Portable Game Notation—a standardized, plain-text format for recording chess games. It was introduced in the early 1990s and quickly became the default way to store, share, and study chess games.
At its core, PGN makes it easy to document and replay games in a format that works across platforms. Whether you’re analyzing Carlsen’s World Championship prep or reviewing your own bullet game from last night, PGN gives you a clean, universal format to work with.
Understanding the PGN Format
A PGN file has two main parts:
- Tags: Information about the game (e.g., players, date, event, result).
- Moves: The actual moves played, recorded in algebraic notation.
Here’s a quick example:
[Event "FIDE World Championship 2021"]
[Site "Dubai UAE"]
[Date "2021.12.07"]
[Round "9.1"]
[White "Nepomniachtchi, Ian"]
[Black "Carlsen, Magnus"]
[Result "0-1"]
[WhiteFideId "4168119"]
[BlackFideId "1503014"]
[WhiteElo "2782"]
[BlackElo "2855"]

Nc5 Nf5 35. a5 Rb8 36. a6 Nxg3 37. Na4 c5 38. a7 Rd8 39.Nxc5 Ra8 0-1
Each [Tag “Value”] line adds context. Then, the move list tells the story of the game from start to finish.
It’s simple, elegant, and powerful.
PGN vs FEN: What’s the Difference?
You may have also seen something called a FEN (Forsyth-Edwards Notation). It looks like a weird string of slashes and numbers—but it has a clear purpose.
• FEN shows a single position—a snapshot of a moment in the game. • PGN shows the whole game, move by move.
Use FEN when you want to set up a specific board state. Use PGN when you want the full story. Most tools support both.
How to Create PGNs
Good news: you probably already have dozens!
Most major chess platforms—like Lichess, Chess.com, or ChessBase—automatically create PGNs for every game you play. You can usually find a “Download PGN” or “Copy PGN” option after any game.
Want to create one manually? Just open an analysis board on your favorite chess platform—every move and variation you play will be automatically recorded into a PGN, ready to export with a single click.
