Verdensranking sjakk: Det internasjonale sjakkforbundet, FIDE er ansvarlig for å oppdatere rankingen.
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor.
The Elo system was originally invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football, American football, baseball, basketball, pool, table tennis, and various board games and esports.
The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent’s is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%.
A player’s Elo rating is represented by a number which may change depending on the outcome of rated games played. After every game, the winning player takes points from the losing one. The difference between the ratings of the winner and loser determines the total number of points gained or lost after a game.
If the higher-rated player wins, then only a few rating points will be taken from the lower-rated player. However, if the lower-rated player scores an upset win, many rating points will be transferred. The lower-rated player will also gain a few points from the higher rated player in the event of a draw.
This means that this rating system is self-correcting. Players whose ratings are too low or too high should, in the long run, do better or worse correspondingly than the rating system predicts and thus gain or lose rating points until the ratings reflect their true playing strength.
Elo ratings are comparative only, and are valid only within the rating pool in which they were calculated, rather than being an absolute measure of a player’s strength.
For top players, the most important rating is their FIDE rating. FIDE has issued the following lists:
- From 1971 to 1980, one list a year was issued.
- From 1981 to 2000, two lists a year were issued, in January and July.
- From July 2000 to July 2009, four lists a year were issued, at the start of January, April, July and October.
- From July 2009 to July 2012, six lists a year were issued, at the start of January, March, May, July, September and November.
- Since July 2012, the list has been updated monthly.
The following analysis of the July 2015 FIDE rating list gives a rough impression of what a given FIDE rating means in terms of world ranking:
- 5323 players had an active rating in the range 2200 to 2299, which is usually associated with the Candidate Master title.
- 2869 players had an active rating in the range 2300 to 2399, which is usually associated with the FIDE Master title.
- 1420 players had an active rating between 2400 and 2499, most of whom had either the International Master or the International Grandmaster title.
- 542 players had an active rating between 2500 and 2599, most of whom had the International Grandmaster title.
- 187 players had an active rating between 2600 and 2699, all of whom had the International Grandmaster title.
- 40 players had an active rating between 2700 and 2799.
- 4 players had an active rating of over 2800. (Magnus Carlsen was rated 2853, and 3 players were rated between 2814 and 2816).
The highest ever FIDE rating was 2882, which Magnus Carlsen had on the May 2014 list. A list of the highest-rated players ever is at Comparison of top chess players throughout history.
