Chess Organizations & the Championship Cycle

FIDE

The Fédération Internationale des Échecs (FIDE), founded in Paris in 1924, is chess's international governing body. Its member federations are individual countries' national chess organizations, and FIDE's core responsibilities include maintaining the official worldwide rating list, awarding titles (Grandmaster and the rest), setting the official rules of play, and organizing the World Championship cycle and the biennial Chess Olympiad.

Below FIDE, most countries have their own national federation (in the United States, US Chess) that runs domestic tournaments, issues national ratings, and selects players to represent the country in FIDE-sanctioned team events.

How a Challenger Is Chosen Today

The modern path to a World Championship match runs through several stages, each narrowing the field:

• Qualifying events — strong results in events like the FIDE World Cup (a large knockout tournament open to a wide field) and the FIDE Grand Swiss earn a small number of players a spot in the next stage.
• The Candidates Tournament — a compact, elite event (traditionally eight players) combining the World Cup and Grand Swiss qualifiers with the highest-rated players in the world and, often, the previous cycle's runner-up. Whoever finishes first earns the right to challenge the reigning champion.
• The World Championship match — the Candidates winner faces the reigning champion in a head-to-head match, decided by classical games and, if still tied, a rapid and blitz tiebreak sequence.

This exact structure has shifted over time — the 1993–2006 split between the Classical and FIDE title lines (explained in detail on Vladimir Kramnik's page) temporarily replaced it with a knockout tournament format before the modern Candidates system was restored.

Major Recurring Elite Tournaments

Beyond the World Championship cycle itself, a handful of elite invitational tournaments make up the backbone of the top-level chess calendar every year — many now grouped together under the Grand Chess Tour, a season-long series with its own standings and prize fund:

• Tata Steel Chess Tournament (Wijk aan Zee, Netherlands) — one of the oldest and most prestigious annual tournaments, running since 1938.
• Norway Chess (Stavanger) — a modern super-tournament known for its unusual "armageddon" tiebreak rule applied to every drawn classical game.
• Sinquefield Cup (Saint Louis) — hosted by the Saint Louis Chess Club, a major hub of elite American chess.
• London Chess Classic — historically one of the season's marquee closing events.
