Open (sport)
In sports, an open tournament, or open competition, indicates anyone may enter the tournament or competition, especially without regard to their professional or amateur status. First used in golf, the term is now used in many different sports and in varying contexts, not always in reference to the amateur or professional status of the players. For example, it might indicate that the competition is "open" to international players. An open competition contrasts with closed and invitational competitions. The term "open" is not always absolute. Minimum performance standards, or eligibility criteria, vary by sport and by individual tournament rules. For example, qualifier entrants to the 2025 U.S. Open golf tournament must have a USGA official handicap of 0.4 or less. Open competitions are also found outside of sports, such as open architectural design competitions. History The earliest known usage of the term was by Prestwick Golf Club in 1861, when it held the second annual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buchholz System
The Buchholz system (also spelled Buchholtz) is a ranking or scoring system developed by Bruno Buchholz (died 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 system is that tie-break s ...

Time Control
A time control is a mechanism in the tournament play of almost all two-player board games so that each round of the match can finish in a timely way and the tournament can proceed. For turn-based games such as chess, shogi or go, time controls are typically enforced by means of a game clock, which counts time spent on each player's turn separately. A player that spends more time than the time control allows is penalized, usually by the loss of the game. Time pressure (or time trouble or ''Zeitnot'') is the situation where one player has very little time on their clock to complete their remaining moves. Classification The amount of time given to each player to complete their moves will vary from game to game. However, most games tend to change the classification of tournaments according to the length of time given to the players. In chess, various classification schemes are used. FIDE defines time controls based on the sum of the amount of time allotted to each player, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
