How the Candidates Tournament works, with the scoring

The short answer: eight players meet twice each over fourteen rounds, scoring one point for a win and half for a draw. Only first place qualifies for the World Championship match, and ties are broken on head-to-head, then most wins.

The Candidates is the hardest tournament in chess to qualify for and, by design, the most brutal to play. There is exactly one prize that matters, and finishing second is worth precisely nothing.

The scoring

Result	Points
Win	1
Draw	0.5
Loss	0

Chess scoring has not changed in a very long time, and the half-point for a draw is the reason the format works at all. It makes a drawn game a genuine partial result rather than a wasted round, which is what allows a player to win a tournament on one victory and thirteen solid draws — a legitimate strategy that has produced champions.

Various alternatives have been trialled, most notably the football-style 3–1–0 system intended to discourage short draws. It has never taken hold at elite level, partly because it distorts the endgame of a tournament in ways players dislike and partly because chess culture is deeply resistant to changing the scoring of a game this old.

The format

Element	Number
Players	8
Format	Double round-robin
Rounds	14
Games against each opponent	2 (one with white, one with black)
Maximum possible score	14
Typical winning score	8½ to 9
Qualifying places	1

Every player faces every other player twice, once with each colour. That symmetry is what makes the result impossible to dispute — nobody had an easier draw, because there was no draw. It is the fairest format in competitive chess and, not coincidentally, the most exhausting.

A winning score of 8½ from 14 means roughly three wins and eleven draws, or four wins, one loss and nine draws. Winning the Candidates does not require dominance. It requires not losing.

How players qualify

Seats come from several distinct routes, and spreading them across formats is deliberate:

Route	Rewards
Previous World Championship runner-up	Proven match play at the highest level
World Cup	Knockout nerve under sudden-death pressure
FIDE Grand Swiss	Consistency across a large, varied field
FIDE Circuit	A full season of results across many events
Rating spot	Sustained elite play over time

No single kind of strength gets you in by itself. A player who is brilliant in knockouts but inconsistent over a season has one route; a metronomically consistent player who freezes in sudden death has another. This is good design — it produces a field of genuinely different players rather than eight versions of the same profile.

Tiebreaks

If players finish level on points, the order applied is typically:

1. Head-to-head result between the tied players
2. Total number of wins
3. Sonneborn–Berger score
4. A rapid or blitz playoff

The “most wins” criterion is quietly one of the best rules in chess. It rewards the player who tried to win games rather than the one who drew safely into a share of first, and it has changed the outcome of major events.

Sonneborn–Berger, the third criterion, is worth a sentence: it sums the scores of the opponents you beat, plus half the scores of those you drew. The logic is that beating the players who finished high should count for more than beating the ones who finished last. It rewards results against strong opposition without needing a separate strength-of-schedule calculation.

Why it produces strange chess

A double round-robin with a single qualifying place turns the final rounds into a game-theory problem rather than a chess problem.

A player half a point behind with one round left must win. That means choosing an opening with winning chances, which necessarily means one with losing chances — you cannot play for a win from a position with no imbalance. A player half a point ahead has to decide whether to hold or press, knowing that a draw may be enough and may not.

Some of the most famous collapses in chess history have happened in round fourteen of a Candidates, and almost none were caused by a lack of ability. They were caused by a player being forced, by the arithmetic, into a position they would never voluntarily have entered.

The colour allocation problem

A subtlety that decides more than it should: in a fourteen-round double round-robin, the order in which you receive white matters. Having white in the final round against a direct rival is a meaningful advantage; having black in rounds twelve, thirteen and fourteen while chasing is close to a sentence.

Pairings are drawn in advance, so this is luck rather than design. It is one of the few genuinely arbitrary elements in an otherwise fair format.

Why the format survives criticism

Every cycle produces suggestions for improvement: a knockout instead, more players, a final match rather than a table. The double round-robin persists because it is the only format in which the winner has demonstrably beaten the field under identical conditions.

A knockout would be more dramatic and considerably less fair. Given that the prize is a shot at the World Championship, fairness is the correct priority.
