Chinese Chess FEN Load and Export

Save, share, and restore positions quickly for review, teaching, and analysis.

FEN is useful because it compresses a board position into one line of text, which makes a position easy to save, search, share, and reload. For review, it is more precise than a screenshot. For teaching, it is more consistent than a verbal description. For continuing analysis across devices, it is faster than copying a full game record. Once you understand the basics, you can turn “I saw this position” into “I can recreate this position anytime.”

Highlights

Import FEN strings with move history.
Useful for teaching, review, and position sharing.
Export the current position and continue elsewhere.
Works well when switching between phone and desktop.

Steps

Click Load FEN and paste the full string, including history if you have it.

If the string includes moves, the page replays them automatically so you can return to the original node.

Once the board is correct, continue with analysis, review, or cloud-book lookup.

When you need to share it again, export the current position and copy it to another device.

Details

What FEN records

FEN is not a game record. It records the position state. In other words, it answers questions like what pieces are on the board, whose turn it is, and whether the current state can support certain rule actions. It does not answer how the game reached that position. That difference matters because many players mix up the state and the process, which leads to confusion when sharing or loading positions.

Turning a position into text gives you portability. You can send one FEN line to a friend or open it again on another device. For exercises, teaching, tournament records, and quick review, this format is compact and accurate. Even more importantly, it is a strong starting point for later analysis because you can feed it directly into the engine, cloud book, or history playback.

FEN describes state, not the full sequence.
One line of text is more precise than a screenshot and easier to reload.
It is a good entry point for exercises, teaching, and cross-device analysis.

Why both load and export matter

Import alone is not enough, and export alone is not enough either. Loading lets you pick up someone else’s position quickly. Exporting lets you save your own analysis and continue later. In real use, the common workflow is to see a position on a phone, load it for analysis, and then export the result to a desktop for deeper work. If that round trip is smooth, FEN becomes genuinely useful.

The page also supports a history-attached form, which matters a lot for review. Often you do not only want “this position,” but also “how did it arise?” When moves are attached after the base FEN, you can reconstruct the whole variation and check it step by step with the engine or cloud book. That preserves both the position and its context.

Import helps you connect to positions shared by others.
Export helps you preserve your own analysis for later.
History-attached FEN is especially useful for review and training.

From FEN to analysis — the complete workflow

Loading a FEN string is just the beginning. Once the position is on the board, you can send it directly to the AI engine for evaluation, check the cloud book for practical win rates, or start a full game review. The real value of FEN is not just saving a position — it is being able to push it through the entire analysis pipeline without re-entering the board state manually.

For puzzle creators, the position editor lets you set up any custom position and export it as FEN. For physical board users, the photo to FEN feature turns a camera shot into a shareable position string. And the FEN examples page provides ready-to-use positions for study and teaching. Together, these tools make FEN the universal bridge between every Xiangqi workflow.

Common Pitfalls

Pitfall 1: Treating FEN as a full game record

FEN records the position state, not the entire move sequence.

Pitfall 2: Ignoring moves after the base FEN

Without moves you lose the history, which makes review less complete.

Pitfall 3: Forgetting to verify the position after loading

Always double-check that the loaded position matches what you intended, especially when the FEN string was typed manually.

Glossary

Base FEN

The core position data without the move history attached.

Moves

The move list appended after FEN so the full variation chain can be restored.

Active side

The side (Red or Black) whose turn it is to move, indicated as w or b in the FEN string.

FEN validation

The process of checking that a FEN string follows the correct format and corresponds to a legal board position.

Examples

Sharing example

A puzzle position can often be shared with base FEN alone, but review works better when moves are included.

Export example

You can inspect the position on your phone and export the same FEN to your desktop for deeper analysis.

Puzzle creation

Set up a custom position in the position editor, then export the FEN to share as a challenge for others.

Photo to FEN

Take a photo of a physical board and let the photo recognition tool convert it to FEN automatically.

FAQ

Can FEN include history

Yes. The page supports the full base FEN plus moves format so you can return to the variation chain.

What happens with invalid input

The app reports the issue and still keeps any valid portion it can parse, which makes correction easier.

Where is this useful

Teaching, sharing game records, puzzle creation, and continuing analysis across devices.

Which is more important, FEN or the game record

They serve different jobs. FEN is better for current state, while a game record is better for the full sequence.

Can I create a FEN from a photo

Yes. Use the Photo to FEN page to capture a physical board and convert it automatically.

How is FEN different from PGN

FEN records a single position state. PGN records the full sequence of moves in a game. See the FEN Guide for a deeper comparison.
