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 reduces ...

Norm (chess)
A norm in chess is a high level of performance in a chess tournament. The level of performance is typically measured in tournament performance rating above a certain threshold (for instance, 2600 for GM norm), and there is a requirement on the level of tournament, for instance by a prescribed minimal number of participants of given title/level one meets. Several norms are among the requirements to receive a title such as Grandmaster from FIDE. Grandmaster norm To qualify for the title of Grandmaster (GM) of chess, a title awarded by FIDE, the World Chess Federation, a player must achieve two or more grandmaster norms in events covering a minimum of 27 games.

Chess Title
A chess title is a title regulated by a chess governing body and bestowed upon players based on their performance and rank. Such titles are usually granted for life. The international chess governing body FIDE grants several titles, the most prestigious of which is Grandmaster; many national chess federations also grant titles such as "National Master". More broadly, the term "master" can refer to any highly skilled chess player. Over-the-board chess In general, a ''chess master'' is a player of such skill that they can usually beat most amateurs. Among chess players, the term is often abbreviated to ''master''. The establishment of the world chess body, Fédération Internationale des Échecs (FIDE), saw the creation of titles superior to the "national master" titles. In 1950, FIDE created the titles " Grandmaster" and " International Master", the requirements for which were increasingly formalized over the years. In 1978, FIDE created the lesser title of "FIDE Master". Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chess Engine
In computer chess, a chess engine is a computer program that analyzes chess or chess variant positions, and generates a move or list of moves that it regards as strongest. A chess engine is usually a back end with a command-line interface with no graphics or windowing. Engines are usually used with a front end, a windowed graphical user interface such as Chessbase or WinBoard that the user can interact with via a keyboard, mouse or touchscreen. This allows the user to play against multiple engines without learning a new user interface for each, and allows different engines to play against each other. Many chess engines are now available for mobile phones and tablets, making them even more accessible. History The meaning of the term "chess engine" has evolved over time. In 1986, Linda and Tony Scherzer entered their program Bebe into the 4th World Computer Chess Championship, running it on "Chess Engine," their brand name for the chess computer hardware made, and marke ...

Sacrifice (chess)
In chess, a sacrifice is a move that gives up a piece with the objective of gaining tactical or positional compensation in other forms. A sacrifice could also be a deliberate exchange of a chess piece of higher value for an opponent's piece of lower value. Any chess piece except the king may be sacrificed. Because players usually try to hold on to their own pieces, offering a sacrifice can come as an unpleasant surprise to one's opponent, putting them off balance and causing them to waste precious time trying to calculate whether the sacrifice is sound or not, and whether to accept it. Sacrificing one's queen (the most valuable piece), or a string of pieces, adds to the surprise, and such games can be awarded . Types of sacrifice Real versus sham Rudolf Spielmann proposed a division between sham and real sacrifices: * In a ''real sacrifice'', the sacrificing player will often have to play on with less than their opponent for quite some time. * In a ''sham sacrifice'', ...

Seed (sports)
A seed is a competitor or team in a sport or other tournament who is given a preliminary ranking for the purposes of the draw. Players/teams are "planted" into the bracket in a manner that is typically intended so that the best do not meet until later in the competition, usually based on regular season. The term was first used in tennis, and is based on the idea of laying out a tournament ladder by arranging slips of paper with the names of players on them the way seeds or seedlings are arranged in a garden: smaller plants up front, larger ones behind. Sometimes the remaining competitors in a single-elimination tournament will be "re-seeded" so that the highest surviving seed is made to play the lowest surviving seed in the next round, the second-highest plays the second-lowest, etc. This may be done after each round, or only at selected intervals. Tennis Professional tennis tournaments seed players based on their rankings. The number of seeds varies from tournament to tournam ...
