The main difference from FIDE's Elo rating system is the combination of all three time controls (classical, rapid and blitz) into a single rating list, whereas FIDE maintains three different rating lists.
The first rating list was published in January 2017, following two years of research. [2]
Monthly rating lists from August 2016 onwards have been retroactively published. [3] The number one player in every rating list so far has been Magnus Carlsen.

A norm in chess is a high level of performance in a chess tournament. The level of performance is typically measured in tournament performance rating above a certain threshold, and there is a requirement on the level of tournament, for instance by a prescribed minimal number of participants of given title/level one meets. Several norms are among the requirements to receive a title such as Grandmaster from FIDE.
Cheating in chess is a deliberate violation of the rules of chess or other behaviour that is intended to give an unfair advantage to a player or team. Cheating can occur in many forms and can take place before, during, or after a game. Commonly cited instances of cheating include: collusion with spectators or other players, use of chess engines during play, rating manipulation, and violations of the touch-move rule. Many suspiciously motivated practices are not comprehensively covered by the rules of chess.

A chess rating system is a system used in chess to estimate the strength of a player, based on their performance versus other players. They are used by organizations such as FIDE, the US Chess Federation, International Correspondence Chess Federation, and the English Chess Federation. Most of the systems are used to recalculate ratings after a tournament or match but some are used to recalculate ratings after individual games. Popular online chess sites such as Chess.com, Lichess, and Internet Chess Club also implement rating systems. In almost all systems, a higher number indicates a stronger player. In general, players' ratings go up if they perform better than expected and down if they perform worse than expected. The magnitude of the change depends on the rating of their opponents. The Elo rating system is currently the most widely used. The Elo-like ratings systems have been adopted in many other contexts, such as other games like Go, in online competitive gaming, and in dating apps.
FIDE titles are awarded by the international chess governing body FIDE for outstanding performance. The highest such title is Grandmaster (GM).

Open titles may be earned by all players, while women's titles are restricted to female players. Many strong female players hold both open and women's titles. FIDE also awards titles for arbiters, organizers and trainers. Titles for correspondence chess, chess problem composition and chess problem solving are no longer administered by FIDE.
