Caracas
Caracas (, ), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the center of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located along the Guaire River in the northern part of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is close to the Caribbean Sea, separated from the coast by a steep 2,200-meter-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The center of the city is still ''Catedral'', located near Bolívar Square, though some consider the center to be Plaza Venezuela, located in the Los Caobos area. Businesses in the city include service companies, banks, and malls. Caracas has a largely service-based economy, apart from some industrial activity in its metropolitan ar ...

Chessmetrics
Chessmetrics is a system for rating chess players devised by Jeff Sonas. It is intended as an improvement over the Elo rating system. Implementation Chessmetrics is a weighted average of past performance. The score considers a player's win percentage against other players weighted by the ratings of the other players and the time elapsed since the match. A 10% increase in performance is equivalent to an increase of 85 rating points. The weighting of previous matches digresses linearly from 100% for just-finished matches to zero for matches conducted more than two years ago. Formulas Performance rating adjustment after tournament: :Performance Rating = Average Opponents' Rating + PctScore - 0.50) * 850/code> Weighting of past tournaments (age in months): :100% * (24 - age) Criticism In 2006 economists Charles C. Moul and John V. C. Nye used Chessmetrics to determine the "expected" results of games, and wrote:Ratings in chess that make use of rigorous statistics to produce goo ...

Elo Rating
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 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 winni ...

Chess Olympiad
The Chess Olympiad is a biennial chess tournament in which teams representing nations of the world compete. FIDE organises the tournament and selects the host nation. Amidst the COVID-19 pandemic, FIDE held an Online Chess Olympiad in 2020 and 2021, with a rapid time control that affected players' online ratings. The use of the name "Chess Olympiad" for FIDE's team championship is of historical origin and implies no connection with the Olympic Games. Birth of the Olympiad The first Olympiad was unofficial. For the 1924 Olympics an attempt was made to include chess in the Olympic Games but this failed because of problems with distinguishing between amateur and professional players. While the 1924 Summer Olympics was taking place in Paris, the 1st unofficial Chess Olympiad also took place in Paris. FIDE was formed on Sunday, July 20, 1924, the closing day of the 1st unofficial Chess Olympiad. FIDE organised the first Official Olympiad in 1927 which took place in London. The O ...

In 1975, Fischer refused to defend his title when an agreement could not be reached with FIDE, chess's international governing body, over the match conditions. Consequently, the Soviet challenger Anatoly Karpov was named World Champion by default. Fischer subseq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
