Champions Chess Tour 2021

The Champions Chess Tour 2021, known for sponsorship reasons as the Meltwater Champions Chess Tour, was a 10-month long series of 10 online chess tournaments featuring the world's top players, playing for a prize money pool of US$1.5 million. The tournament games are held on chess24.com and are broadcast on Twitch, YouTube, chess24.com itself, and the tour's official website. The tour started on November 22, 2020, and lasted until October 4, 2021. The tournaments were not rated by FIDE.

Format
There are 10 total tournaments in the tour: 6 labelled as Regular, 3 labelled as Major, and 1 Final. Each takes place towards the end of a month over the course of 9 days.

Qualification
According to the tour regulations, there are 16 spots in a Regular tournament, 12 spots in a Major tournament, and 10 spots in the Final tournament. However, after the first Major tournament (Airthings Masters), it was concluded that 8 out of 12 players advancing to the knockout round rewarded cautious play, and the remaining Major tournaments (Magnus Carlsen Invitational and FTX Crypto Cup) were conducted with 16 players.

For each of the Regular tournaments except for the first one, 8 of the 16 spots are given to the current top 8 players in the Tour Rankings. The rest of the spots are given out via wild cards, invitations, or popular votes. The 16 spots for the first tournament of the tour are chosen via the decision of the event organizers.

For the Major tournaments, 8 of the spots are also given to the current top 8 players in the Tour Rankings. The winner of the preceding Regular tournament is also given a spot, if he or she is not already in the top 8. The rest of the spots are given via wild cards.

For the Final tournament, 8 of the 10 spots are given first to the winners of the 3 Major tournaments, then down the standings of the Tour Rankings. The final 2 spots are given to the best-performing "Tour Ambassadors."

Time controls
Three different time controls are used in the tour:


 * In rapid games, each player has 15 minutes, plus a 10-second increment for each move.
 * In blitz games, each player has 5 minutes, plus a 3-second increment for each move.
 * In Armageddon games, white has 5 minutes, black has 4 minutes, there is no increment, and black wins the tie in case of a draw.

Regular
The Regular tournaments consist of a preliminary round and 3 knockout rounds. In the preliminary round, the 16 players participate in a round-robin spanning 3 days (5 games per day), with each player playing the other players for 1 rapid game, for a total of 120 games. The top 8 players with the most points advance to the next round and are seeded for the purposes of making the bracket based on their points. In the event that 2 or more players are tied with points, the following system is used:
 * 1) Points won in matches involving the tied players
 * 2) Number of wins
 * 3) Sonneborn–Berger score
 * 4) Koya score

In the knockout rounds, each matchup consists of 2 matches of 4 rapid games on back-to-back days. If either player wins one match and at least draws the other, he advances on to the next round. If each player wins one match or both matches are drawn, immediately following the second match, the players play 2 blitz games. If the blitz games are split, the winner is determined via an Armageddon game. The higher seed in each matchup picks the color for the first game, the first tiebreaker, and the Armageddon. In addition to the games between players who advanced, there is also a match for third place between the semifinal losers.

Major
The Major tournaments operate the same way as the Regular tournaments. It is still the top 8 players who qualify for the knockout rounds.

Final
The Final only consists of one round-robin for the 10 players, spanning 9 days (1 matchup per day). Each matchup will comprise 4 rapid games. If the 4 points are split among the two players, then 2 blitz games are played, followed by Armageddon if the blitz games are split. 3 points are awarded for an outright win (no tiebreak needed), 2 points are awarded for a tiebreak win, and 1 point is awarded for a tiebreak loss.

In addition to these points, the players start off with bonus points based on their Tour rankings coming into the Final. The player with the fewest Tour points gets 0 bonus points, and the other players are awarded half a point for every full 10 points they have more than the player with the least number. For example, if Player A has the fewest Tour points with 86, a Player B with 143 Tour points will be awarded 2.5 points, since they exceed Player A's total by 57 (no rounding).

The player with the greatest sum of bonus points and points won in the Final will be crowned the Tour Champion.

Tour points
For Regular tournaments, points are awarded as follows.

In other words, a player receives 10 points for winning in the quarterfinals, 15 points for winning in the semifinals, 15 points for winning the final and 5 points for winning the match for third place. The regulations were present for most of the tournament, excluding the Skilling Open tournament; in that tournament of the tour, the runner-up was awarded 20 points and the two remaining semi-finalists were each awarded 10 points, without a match for 3rd place.

Additional points are also awarded to finishes in the preliminary round:

The points system for Major tournaments is the same, but all values are doubled.

In the event that two players are tied for the same number of Tour points, the following tiebreak system will be used:
 * 1) Number of tournament wins
 * 2) Number of tournament appearances (fewer is better)
 * 3) Number of final appearances
 * 4) Number of semi-final appearances
 * 5) Number of quarter-final appearances

The administrators of the tournament also have the right to substitute a tiebreak match if the tie is for a qualification spot.
