Candidates: World Championship challenger qualifier
Candidates
Definition
The Candidates (often “FIDE Candidates Tournament” or historically “Candidates matches”) is the elite event that determines the official challenger for the World Chess Championship. Organized by FIDE, the Candidates sits at the heart of the World championship cycle. Its winner earns the right to play the reigning World champion in a title match (or, in some past cycles, to enter a final candidates playoff that produced the challenger).
Not to be confused with “candidate moves” (a calculation method popularized by Kotov), the term “Candidates” in modern usage almost always refers to the qualifier event for the world title match.
How it is used in chess
Players and commentators use “Candidates” as shorthand for the event (“He qualified for the Candidates”) and also to refer to a player participating in it (“a Candidates player this cycle”). Journalists and fans track “Candidates spots,” meaning the limited qualification places available each cycle.
Why it matters
Winning the Candidates is the most prestigious achievement short of becoming World Champion. The event’s pressure, preparation depth, and razor-thin Practical chances produce landmark games and heavily influence Opening Theory. Many famous novelties, epic defenses, and high-stakes Swindle attempts first appeared here.
Formats, qualification paths, and tie-breaks
Formats over time
- 1950–1962: Large round-robin Candidates tournaments decided the challenger.
- 1965–1985: Candidates knockout matches (quarterfinals, semifinals, final).
- 2007: An 8-player double round-robin (Mexico City) directly produced a World Champion; cycles later reverted to Candidates determining a challenger.
- 2011: Return to matches format (Kazan).
- 2013–present: Generally 8-player double round-robin tournaments (ongoing refinements by FIDE).
- Women’s Candidates: Parallel event determining the challenger for the Women’s World Championship, held in various formats (recently tournament format).

- Reigning World Championship match loser (often seeded).
- Occasional organizer wildcard(s) as defined by regulations.
Tie-breaks and playoffs
Modern Candidates events publish a strict Tiebreak system before the start (e.g., head-to-head, number of wins, Sonneborn-Berger, or rapid/blitz playoffs). Famous example: London Candidates 2013 ended with Carlsen and Kramnik tied; Carlsen became challenger on the “more wins” tiebreak. Some cycles also schedule over-the-board Playoff games (rapid/blitz/Armageddon) if needed.
Strategic and historical significance
Impact on chess strategy
- Preparation depth: Candidates contenders bring state-of-the-art Home prep powered by top Engine analysis, often unveiling a decisive Novelty or Prepared variation at key moments.
