How it is checked

Area and scope

The area is Oslo municipality and the Akershus municipalities where Oslo players go for a game or a tournament: Bærum, Asker, Lillestrøm, Lørenskog, Rælingen, Nittedal, Nordre Follo, Ås, Vestby, Nesodden, Ullensaker, Eidsvoll and Nes. Place names are written in Norwegian, as the municipalities write them.

Nothing here is rated, ranked or paid for, and no place is pushed ahead of another. In each list the cards with the newest evidence come first; places that have closed or moved are kept at the end of the page that shows every card.

Where the facts come from

The starting point is the club register of Norges Sjakkforbund, the Norwegian Chess Federation, together with its calendar of events. Then come the FIDE list of rated tournaments for Norway, the pages of the Oslo district association and its youth association, the Brønnøysund business register (Enhetsregisteret) for clubs with no site of their own, and the websites of the clubs, organisers and venues themselves.

Every fact on a card ends in a small number that leads to its source: a short quotation in the page's own language, mostly Norwegian, and the day the page was opened. The card's text summarises those quotations and states nothing that no page says.

Where two pages disagree, for instance a register address and a club's own playing place, the card gives both and does not quietly pick one.

Three kinds of source

Official means the page comes from the place, its organiser or a chess body; secondary means a third party reports it, such as a directory, a guide or a newspaper; unverified means a user contribution or a single mention with nothing behind it.

The mark says who is speaking, not whether they are right. A register entry can outlive the club it describes, which is why the date of a trace weighs as much as its mark.

When a page is silent

Few Oslo clubs print their membership fee for adults, and fewer say in words whether a stranger may join a club evening. Where no page answers, the card shows "not stated by sources"; an empty field never means no.

If you know a page that fills a gap, send it through the form. It is checked and added, with its date, when the directory is next revised.

What is not judged

• No club, bar, coach, school or tournament gets a grade, a score or a rank.
• The cards rest on published pages; nobody visits the venues for the directory.
• Prices are quoted as a page showed them on the day it was opened and are not checked on site.
• Club evenings follow the school year and can change before a card is revised.
• The quality of teaching is not assessed; a coach's title is only compared with the FIDE profile.
• Step-free access, building opening hours and similar practical points are not examined.
• Attendance is not counted: a card cannot say how many players turn up on an evening.
• An empty field only means that no page answered; it is not a no.

If a card concerns you

Club boards, organisers, coaches, venue staff and members can correct a card through the corrections form. A link to a page that shows the right fact makes the change quick.

Each accepted correction is dated in the edit notes and recorded on the card it concerns. A place that prefers not to be listed can say so through the same form, and its card is taken down at the next revision.

Dates and revisions

The pages behind the current cards were opened between 15 October 2026 and 15 October 2026. The date beside each source on a card shows how old that piece of evidence is.

The whole directory is read again roughly every 6 months. In the meantime a club may change its evening or its room before the card follows; the club's own page has the last word.

Who runs it

Oslo Chess is an independent editorial project. It takes no money from clubs, organisers, schools, bars or shops, carries no advertising and has no tie to Norges Sjakkforbund or any district association.

It exists because chess around Oslo is spread over a federation register, an event calendar, a rating list and dozens of club sites that each hold one piece. The corrections form is how players and clubs keep it accurate between revisions.

Reusing the data

The full directory can be downloaded as a JSON file, one record per card with every source, mark and date. It is published under the Creative Commons Attribution 4.0 licence; credit Oslo Chess when you reuse it.

For language models and other programs, a plain-text outline of Oslo Chess sits at llms.txt.

Checked and left out

Entries checked and not listed: 14. Typical reasons are a club outside Oslo and Akershus with no tie to the area, a one-off event with no second edition, a hall that hosted a single tournament, or a group that plays only online.

Map pins

A card carries a pin when a source gives a map position or when its address is found as a building in OpenStreetMap's address search. A pin found by search is marked approximate.

No pin is placed by hand, the site draws no map of its own, and the map link opens openstreetmap.org. Map data is © OpenStreetMap contributors and available under the Open Database Licence (ODbL).
