Golden Knights (chess)
The Golden Knights is the United States open correspondence chess championship. It is held annually by the United States Chess Federation (USCF), and is open to all members of the USCF residing in the United States or who have an APO or FPO address. It was first held in 1943 under the name Victory Tournament, the next year it was called the Postal Chess Championship and in 1945 it was finally renamed as the Golden Knights tournament. The 69th annual Golden Knights tournament began in 2016. About 200 players typically participate in each tournament. The tournament is played in three stages: the preliminaries, semi-finals, and finals. At each stage, the participants are divided into a number of seven-player sections, with each participant playing one game (three with White, three with Black) against every other player in the section. Each participant plays in the preliminaries, playing in a section with players having a wide range of ratings. The top finishers in the preliminaries ...

Open (sport)
In sports, an open is a sporting event or game tournament that is open to contestants regardless of their professional or amateur status, age, ability, gender, sex, or other categorization. In many sports, preliminary qualifying events, open to all entrants, are held to successively reduce the field to a manageable number for participation in a final championship event, which itself may involve elimination rounds (tournaments). The term ''open'' may not be absolute. For example, in the U.S. Open in golf, entrants at qualifying events must have a USGA official handicap of 1.4 or less. Other minimum performance standards or eligibility criteria may apply in other sports. Opens are usually found in golf, tennis, bowling, badminton, quizbowl, fighting games, snooker, darts, volleyball, ultimate, squash, CrossFit, Chess, and pickleball Pickleball is an indoor or outdoor racket/paddle sport where two players (singles), or four players (doubles), hit a perforated hollow polymer ...

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.

Championship
In sport, a championship is a competition in which the aim is to decide which individual or team is the champion. Championship systems Various forms of competition can be referred to by the term championship. Title match system In this system, a competitor has to challenge the current champion to win the championship. A competitor (called ''number 1 contender'') can challenge the current champion after defeating other challengers. This form of championship is used in individual head-to-head competitions and is particularly associated with combat sports such as wrestling, boxing and mixed martial arts. Tournament system The term championships (in the plural) is often used to refer to tournament competitions, either using a knockout format, such as at Wimbledon and other championships in tennis, or a mixed format with a group stage followed by knockout rounds, such as used in the European Football Championships. A variation of the knockout format is the "best-of-X" or ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Chess Federation
The United States Chess Federation (also known as US Chess or USCF) is the governing body for chess competition in the United States and represents the U.S. in FIDE, the World Chess Federation. US Chess administers the official national rating system, awards national titles, sanctions over twenty national championships annually, and publishes two magazines: ''Chess Life'' and '' Chess Life for Kids''. The USCF was founded and incorporated in Illinois in 1939, from the merger of two older chess organizations. It is a 501(c)(3) non-profit organization headquartered in St. Louis, Missouri. Its membership as COVID hit was 97,000; as of July 2022 it is 85,000. History In 1939, the United States of America Chess Federation was created in Illinois through the merger of the American Chess Federation and National Chess Federation. The American Chess Federation, formerly the Western Chess Association, had held an annual open championship since 1900; that tournament, after the merger, ...

Military Mail
Military mail, as opposed to civilian mail, refers to the postal services provided by armed forces that allow serving members to send and receive mail. Military mail systems are often subsidized to ensure that military mail does not cost the sender any more than normal domestic mail. In some cases, military personnel in a combat zone may post letters and packages to their home country free of charge. Modern military mail services are provided by most armed forces around the world. In some nations, individual service branches may run their own military mail program. History Early forms of military mail may go back to the dawn of civilization. There is some evidence of it dating back to Ancient Egypt of the 2nd millennium BC. The ''Anglo-Saxon Chronicle'' make mention of messengers being sent by King Edward the Elder (899-924) to recall members of the Kent fyrd, but it is generally regarded that the origins of the postal services stem from the King's Messengers (''Nuncii et Curs ...

Tournament
A tournament is a competition involving at least three competitors, all participating in a sport or game. More specifically, the term may be used in either of two overlapping senses: # One or more competitions held at a single venue and concentrated into a relatively short time interval. # A competition involving a number of matches, each involving a subset of the competitors, with the overall tournament winner determined based on the combined results of these individual matches. These are common in those sports and games where each match must involve a small number of competitors: often precisely two, as in most team sports, racket sports and combat sports, many card games and board games, and many forms of competitive debating. Such tournaments allow large numbers to compete against each other in spite of the restriction on numbers in a single match. These two senses are distinct. All golf tournaments meet the first definition, but while match play tournaments meet the sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-finals
A single-elimination, knockout, or sudden death tournament is a type of elimination tournament where the loser of each match-up is immediately eliminated from the tournament. Each winner will play another in the next round, until the final match-up, whose winner becomes the tournament champion. Each match-up may be a single match or several, for example two-legged ties in European sports or best-of series in American pro sports. Defeated competitors may play no further part after losing, or may participate in "consolation" or "classification" matches against other losers to determine the lower final rankings; for example, a third place playoff between losing semi-finalists. In a shootout poker tournament, there are more than two players competing at each table, and sometimes more than one progressing to the next round. Some competitions are held with a pure single-elimination tournament system. Others have many phases, with the last being a single-elimination final stage, ofte ...

Final (competition)
The final of a competition is the match or round in which the winner of the entire event is decided. In sports competitions following a knockout system, where only two individuals or teams compete in each match, the final is usually played between the winners of two semi-finals. However, if more than two entrants are required for each match, then qualification for the final may be through some other process such as winning ''heats''. The final is usually, but not always, the last match in a tournament to be played, and the winner of this match is declared the winner of the whole tournament. In many contests, the winner(s) and runner(s)-up receive gold and silver medals respectively. Another game, or competition, between the two players who lost in the semi-finals is done to determine who receives the bronze medal. If the final round is contested in a "best-of" format (like "best-of-7"), the term is sometimes called "finals," (playoffs) to denote that there is more than one game ...

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 winn ...

Coefficient
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression; it is usually a number, but may be any expression (including variables such as , and ). When the coefficients are themselves variables, they may also be called parameters. For example, the polynomial 2x^2-x+3 has coefficients 2, −1, and 3, and the powers of the variable x in the polynomial ax^2+bx+c have coefficient parameters a, b, and c. The constant coefficient is the coefficient not attached to variables in an expression. For example, the constant coefficients of the expressions above are the number 3 and the parameter ''c'', respectively. The coefficient attached to the highest degree of the variable in a polynomial is referred to as the leading coefficient. For example, in the expressions above, the leading coefficients are 2 and ''a'', respectively. Terminology and definition In mathematics, a coefficient is a multiplicative factor in some term ...

Draw (chess)
In chess, there are a number of ways that a game can end in a draw, neither player winning. Draws are codified by various rules of chess including stalemate (when the player to move is not in check but has no legal move), threefold repetition (when the same position occurs three times with the same player to move), and the fifty-move rule (when the last fifty successive moves made by both players contain no or pawn move). Under the standard FIDE rules, a draw also occurs in a dead position (when no sequence of legal moves can lead to checkmate), most commonly when neither player has sufficient to checkmate the opponent. Unless specific tournament rules forbid it, players may agree to a draw at any time. Ethical considerations may make a draw uncustomary in situations where at least one player has a reasonable chance of winning. For example, a draw could be called after a move or two, but this would likely be thought unsporting. In the 19th century, some tournaments, notab ...
