Chess Rating Systems
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 (USCF or US Chess), 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 first modern rating system was used by the Correspondence Chess League of America in 1939. Soviet player Andrey Khacha ...

Chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

Grandmaster (chess)
Grandmaster (GM) is a title awarded to chess players by the world chess organization FIDE. Apart from World Champion, Grandmaster is the highest title a chess player can attain. Once achieved, the title is held for life, though exceptionally it has been revoked for cheating. The title of Grandmaster, along with the lesser FIDE titles of International Master (IM) and FIDE Master (FM), is open to all players regardless of gender. The great majority of grandmasters are men, but 40 women have been awarded the GM title as of 2022, out of a total of about 2000 grandmasters. Since about the year 2000, most of the top 10 women have held the GM title. There is also a Woman Grandmaster title with lower requirements awarded only to women. There are also Grandmaster titles for composers and solvers of chess problems, awarded by the World Federation for Chess Composition (see List of grandmasters for chess composition). The International Correspondence Chess Federation (ICCF) awards the tit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Chess Tour
The Grand Chess Tour (GCT) is a circuit of chess tournaments where players compete for multiple prize pools. Major tournaments that have been featured in the Grand Chess Tour include Norway Chess, the Sinquefield Cup, and the London Chess Classic. History The Grand Chess Tour was announced on April 24, 2015, at the Chess Club and Scholastic Center of Saint Louis in St. Louis, Missouri prior to the Battle of the Legends: Garry Kasparov vs Nigel Short match. The tour was designed to promote competitive chess by including all of the top players and the World Champion Magnus Carlsen in a single circuit.

Mark Glickman
The Glicko rating system and Glicko-2 rating system are methods of assessing a player's strength in games of skill, such as chess and Go. The Glicko rating system was invented by Mark Glickman in 1995 as an improvement on the Elo rating system, and initially intended for the primary use as a chess rating system. Glickman's principal contribution to measurement is "ratings reliability", called RD, for ''ratings deviation''. Overview Mark Glickman created the Glicko rating system in 1995 as an improvement on the Elo rating system. Both the Glicko and Glicko-2 rating systems are under public domain and have been implemented on game servers online (like Pokémon Showdown, Pokémon Go, Lichess, Free Internet Chess Server, Chess.com, Online Go Server (OGS), Counter Strike: Global Offensive, Quake Live, Team Fortress 2, Dota Underlords, Guild Wars 2, Splatoon 2, Dominion Online, TETR.IO, and competitive programming competitions.

Jeff Sonas
Jeff Sonas is a statistical chess analyst who invented the Chessmetrics system for rating chess players, which is intended as an improvement on the Elo rating system. He is the founder and proprietor of the Chessmetrics.com website, which gives Sonas' calculations of the ratings of current players and historical ratings going back as far as January 1843. Sonas has written dozens of articles since 1999 for ChessBase.com and other chess websites. He was a participant in the FIDE ratings committee meeting in Athens, Greece in June 2010. In 2002 he wrote for chessbase.com that a 24 k-factor would be ideal for predicting game results, instead of the standard 10 for high level players. In 2009 John Nunn wrote he needed more proof for the change. Sonas replied saying Nunn didn't thoroughly read his first article, but also says there is room for improvement, as he didn't analyze what it should be for low level players. In 2011 after analyzing 1.5 million FIDE rated games, he demonstrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Free Internet Chess Server
The Free Internet Chess Server (FICS) is a volunteer-run Internet chess server. It was organised as a free alternative to the Internet Chess Club (ICC), after that site began charging for membership. History The first Internet chess server, named the Internet Chess Server (ICS), started in January 1992. The software was coded, supported, and operated by volunteers until 1995, when administrators began charging players for membership and changed the name to ICC. Several former ICS programmers saw the commercialisation of ICS as an exploitation of their work. This group, led by Chris Petroff and Henrik Gram, developed FICS as an alternative to the paid model, giving users free, unrestricted access. The server debuted on . In 1998, the Free Internet Chess Organization (FICS) was organized as a nonprofit organization. In 2007, the legal entity was involuntarily dissolved. The server is still maintained and administered by volunteers. In 2016, 50,000 active players played a total ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Correspondence Chess
Correspondence chess is chess played by various forms of long-distance correspondence, traditionally through the postal system. Today it is usually played through a correspondence chess server, a public internet chess forum, or email. Less common methods that have been employed include fax, homing pigeon and phone. It is in contrast to (OTB) chess, where the players sit at a chessboard at the same time, or play each other in real time via the internet. Correspondence chess allows people or clubs who are geographically distant to play one another without meeting in person. These distant relationships are just one of the many distinct appeals of correspondence chess. The length of a game played by correspondence can vary depending on the method used to transmit moves: a game played via server or by email might last no more than a few days, weeks, or months; a game played by post between players in different countries might last several years.

Vlastimil Hort
Vlastimil Hort (born 12 January 1944) is a German chess Grandmaster. During the 1960s and 1970s he was one of the world's strongest players and reached the 1977–78 Candidates Tournament for the World Chess Championship, but never qualified for a competition for the actual title. Hort was born in Kladno, Czechoslovakia and was a citizen of Czechoslovakia for the first part of his chess career. He achieved the Grandmaster title in 1965. He won a number of major international tournaments (Hastings 1967–68, Skopje 1969, etc.) and national championships (1970, 1971, 1972, 1975, and 1977). He gained recognition as one of the strongest non-Soviet players in the world, which led to him representing the "World" team in the great "USSR vs. Rest of the World" match of 1970, where he occupied fourth board and had an undefeated +1 score against the Soviet Grandmaster Lev Polugaevsky—in some respects his greatest result. He defected to the West in 1985, moving to West Germany and winn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
