Export a completed game as PGN, then paste the text or upload the file into your review tool. PGN contains the game moves, so the analyzer can reconstruct the board without accessing your playing account.
This is a useful fallback when a username search cannot find a game or an external service is unavailable. You do not have to solve the synchronization problem before studying the game you already played.
PGN stands for Portable Game Notation. The PGN specification defines a text format with game information and movetext. The game information may identify the players, event, date, and result; the movetext records the sequence on the board.
Key takeaways
- Export one completed standard-chess game when importing into ChessStep.
- A PGN game and a FEN position are different kinds of input.
- Check the first and last positions after import, not just whether a file opened.
Get the game score from the place you played
Open the completed game on your playing platform and look for its PGN export, download, or sharing control. Labels and locations vary between desktop and mobile interfaces. Choose the game-score text or .pgn file rather than a screenshot or a link to the game's web page.
If a sharing menu offers several formats, inspect what you copied. PGN normally contains numbered moves such as 1. e4 e5 2. Nf3 Nc6. A URL beginning with https:// is a link to a game, not its move record.
For games played in ChessStep's friend rooms, the finished-game screen has a Download PGN button. Keep that file if you want a separate copy beyond the account's replay.
Know what a small PGN looks like
This complete miniature is an instructional example, not a game attributed to real players:
[Event "PGN import example"]
[White "Example White"]
[Black "Example Black"]
[Result "0-1"]
1. f3 e5 2. g4 Qh4# 0-1
The square-bracketed lines are headers. The moves come afterward. # marks checkmate, and 0-1 records a Black win. The PGN specification describes these notation conventions; they are not product-specific labels.
Open ChessStep's review page, select Paste PGN, paste the entire example, and choose Open game. You should be able to replay four half-moves, ending with Black's queen on h4 and White checkmated.
Opening the board and running analysis are separate operations. First make sure the imported moves are right. There is no value in analyzing a different game because the clipboard contained the wrong text.
Use FEN for a position, PGN for a game
A FEN describes a board position, the side to move, and related state such as castling rights. It does not contain all the preceding moves. That makes it useful for setting up an exercise, but insufficient for reconstructing a full game's history.
| What you have | What it can provide |
|---|---|
| A single-game PGN | The move sequence and any included game headers. |
| A FEN | A starting position and position-state fields. |
| A board screenshot | A visual arrangement that still needs interpretation. |
| A game URL | An address that another service may or may not support importing. |
ChessStep's current review importer expects a game with moves. A bare FEN is not accepted as a complete game. Nonstandard-start PGNs use SetUp and FEN headers under the specification, but unusual variants and exporter-specific extensions may require a different tool.
Troubleshoot the first failure, not the whole file at once
If the importer rejects the PGN, begin with the error category:
- No moves found: you may have copied only headers, a FEN, or a link.
- Multiple games: export a single game instead of a monthly collection.
- Invalid move or position: obtain a fresh export and check whether the game uses standard chess rules.
- File too large: the current upload limit is under 200 KB for one game.
- Game too long: the browser review currently accepts up to 300 half-moves, or 150 full moves.
Do not delete an illegal-looking move at random. One wrong earlier move can make a later, correctly recorded move impossible. Compare from the start and identify the first point at which the replay diverges.
If a copied file contains commentary and side variations, preserve the original and try a plain main-line export from the source tool. This is a compatibility step, not a reason to discard your only annotated copy.
Understand what username import does
The Chess.com Published-Data API provides read-only access to public data, including game archives. That is why a tool can offer public-username lookup without asking for your Chess.com password. It is not the same as linking a private account or retrieving the site's private review report.
ChessStep offers that public lookup, but availability depends on the external service and ChessStep’s import service succeeding. It is a convenience, not a guarantee of complete history or immediate synchronization. If the desired game is absent, PGN gives you a direct path forward.
Keep a copy you can recognize later
Give the file a useful local name, such as the date and a short learning theme. Retain the original PGN before editing annotations. Be aware that headers may contain names or other details you do not want to publish.
Imported review and saved practice are also different. Importing a game does not automatically save every move as an exercise. Save a position explicitly; guest records stay in this browser, and signing in merges and syncs learning records to your account. Then follow the one-lesson review routine.
The successful outcome is simple: the right game opens, the moves replay correctly, and you can investigate the moment that brought you to the analyzer.
