Why Import from Caissa?

Caissa Chess is a tournament registration and live-results service used by many clubs and organizers. TournaChess can import a Caissa event — sections, players, rounds, games, and standings — directly from its URL.

This is useful when you want to:

  • Keep all your club results in one place. Events you ran on Caissa live alongside your TournaChess tournaments, with the same standings pages, history, and player records.

  • Bring historical events into TournaChess. Import past Caissa events so they can be viewed, shared, and included in Grand Prix scoring.

  • Follow an event that is still running. Unlike a completed-events-only import, a Caissa event that is still in progress can be imported and then re-synced as later rounds are paired and results come in.

Prerequisites

Before you import:

  • You need the Tournament Director role (or higher) in your club.

  • You need the Caissa event URL. Open the event on Caissa and copy the URL from your browser's address bar. Both the live-results and registration URLs work:

    • https://caissachess.net/live/8338
    • https://caissachess.net/register/9203

    A trailing sub-path (for example https://caissachess.net/register/9203/players) is fine — TournaChess reads the event number from the URL.

How to Import

  1. Go to your club's Tournaments page.
  2. Click the Import dropdown and select Import from Caissa.
  3. Paste the Caissa event URL and click Import.
  4. When the import completes, you'll see a summary with the tournament name, the number of sections, and the number of players. Click through to view the imported tournament.

Tip: The Import from Caissa action is also available in the Quick Actions sidebar on your club's homepage.

Large events take a moment while TournaChess fetches every section, round, and pairing from Caissa.

What Gets Imported

TournaChess reconstructs the event from the data Caissa publishes:

  • Tournament details — Event name, start and end dates, and the event description. City, state, ZIP, and the USCF affiliate ID are carried over when Caissa provides them, and a link back to the original Caissa event is added to the description.

  • Sections — Each Caissa section becomes a TournaChess section, preserving its name, time control, and rating ceiling.

  • Players — Every player is imported with their name, USCF ID, rating, team, and grade, and a registration is created for them in the correct section.

  • Rounds and games — Every paired round is recreated with board numbers, colors, results, and byes.

  • Standings — Scores are imported along with each player's initial rating, performance rating, and estimated post-event rating.

Imported tournaments use the club's timezone for start times. Caissa does not publish a timezone, so the club setting is the best available source — check the tournament's start time after importing if your club's timezone is not set.

Rating Type

A section is imported as USCF-rated when Caissa reports it as rated and at least one player in it has a USCF ID. Sections Caissa reports as unrated — or rated sections where no player has a USCF ID — are imported as unrated.

Tournament Status

The imported tournament's status is derived from the event itself. If any section has a round actively being paired on Caissa, the tournament is imported as Active; otherwise it is imported as Complete.

Duplicate Detection

Each club can import a given Caissa event only once. If you try to import an event your club has already imported, the import is rejected and the error names the existing tournament. To pick up newer data from Caissa, re-sync the existing tournament instead of importing it again.

Re-syncing from Caissa

An imported tournament stays linked to its Caissa event, so you can pull fresh data at any time — useful while an event is still running, or after results are corrected on Caissa.

  1. Open the tournament and go to the Pairings tab.
  2. Click Tournament Actions (the ... menu) and select Re-sync from Caissa.

The re-sync is incremental: TournaChess compares what it already has against the current Caissa data and applies only the differences. New sections, players, rounds, and games are added; changed results and standings are updated; and games that no longer exist on Caissa are removed. The summary reports exactly what changed.

Re-sync only appears on tournaments that were imported from Caissa. Tournaments created in TournaChess, or imported from another source, have no Caissa event to sync against.

Limitations

  • Players import as guest players. Caissa players are not matched to existing TournaChess member accounts, even when the same person has an account in your club. You can link a guest player to a member later from the Registrations tab.

  • Re-sync is one-way. It pulls from Caissa and overwrites the corresponding TournaChess data. Edits you make in TournaChess to imported rounds, games, or standings will be replaced the next time you re-sync, and are never pushed back to Caissa.

  • Only what Caissa publishes. Details Caissa does not expose — such as the event timezone, registration fees, or payment status — are not imported.
