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, ...

Elo Rating System
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 wi ...

Sonneborn–Berger Score
The Sonneborn–Berger score (or the Neustadtl score) is a scoring system often used to break ties in chess tournaments. It is computed by summing the conventional score of each defeated opponent, and half the conventional score of each drawn opponent. Neustadtl score is named after Hermann Neustadtl, who proposed it in a letter published in '' Chess Monthly'' in 1882. It is often called the Sonneborn–Berger score, though this is something of a misnomer, since William Sonneborn and Johann Berger were strong critics of the system; they proposed their own scoring system that added in the square of the raw score of each player, which would help if the system was used as the scoring system for some types of tournaments, but would not help with breaking ties between players with conventional scoring. As such, although theoretically equivalent to the current method, albeit more complicated, the ''Non-Neustadtl Sonneborn–Berger score'' has never been popular for tiebreaks. More ...

Buchholz System
The Buchholz system (also spelled Buchholtz) is a ranking or scoring system in chess developed by Bruno Buchholz (died ca. 1958) in 1932, for Swiss system tournaments . It was originally developed as an auxiliary scoring method, but more recently it has been used as a tie-breaking system. It was probably first used in the 1932 Bitterfeld tournament. It was designed to replace the Neustadtl score . The method is to give each player a raw score of one point for each win and a half point for each draw. When used as an alternative scoring system, each player's Buchholz score is calculated by adding the raw scores of each of the opponents they played and multiplying this total by the player's raw score . When used for tie-breaking among players with the same raw score, no multiplying is necessary and the sum of the raw scores of the opponents played is used to break ties . When used as a tie-break system, it is equivalent to the Solkoff system. The major criticism of this syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swiss System Tournament
A Swiss-system tournament is a non-eliminating tournament format that features a fixed number of rounds of competition, but considerably fewer than for a round-robin tournament; thus each competitor (team or individual) does not play all the other competitors. Competitors meet one-on-one in each round and are paired using a set of rules designed to ensure that each competitor plays opponents with a similar running score, but does not play the same opponent more than once. The winner is the competitor with the highest aggregate points earned in all rounds. With an even number of participants, all competitors play in each round. The Swiss system is used for competitions in which there are too many entrants for a full round-robin (all-play-all) to be feasible, and eliminating any competitors before the end of the tournament is undesirable. In contrast, all-play-all is suitable if there are a small number of competitors; whereas a single-elimination (knockout) tournament rapidly reduc ...
