Fivefold Repetition
In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position.Article 14K.2 in Two positions are by definition "the same" if pieces of the same type and color occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture ''en passant'' is the same. The repeated positions need not occur in succession. The game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter. The claim must be made either before making the move which will produce the third repetition, or after the opponent has made a move producing a third repetition. By contrast, the fivefold repetition rule requires the arbiter to intervene and declare the game drawn if the same position occurs ...

Resign (chess)
The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king; checkmate occurs when a king is threatened with capture and has no escape. A game can end in various ways besides checkmate: a player can resign, and there are several ways a game can end in a draw. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from region to region. Today, the standard rules are set by FIDE (Fédération Internationale des Échecs), the international governing body for chess. Slight modifications are made by some national organizations for their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blunder (chess)
In chess, a blunder is a critically bad mistake that severely worsens the player's position by allowing a loss of , checkmate, or anything similar. It is usually caused by some tactical oversight, whether due to time trouble, overconfidence, or carelessness. Although blunders are most common in beginner games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in chess. What qualifies as a blunder rather than a normal mistake is somewhat subjective. A weak move from a novice player might be explained by the player's lack of skill, while the same move from a master might be called a blunder. In chess annotation, blunders are typically marked with two question marks ("??") after the move notation. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's . In particular, checks, , and need to be considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Emanuel Lasker
Emanuel Lasker (; December 24, 1868 – January 11, 1941) was a German chess player, mathematician, and philosopher. He was the second World Chess Champion, holding the title for 27 years, from 1894 to 1921, the longest reign of any officially recognised World Chess Champion, winning 6 World Chess Championships. In his prime, Lasker was one of the most dominant champions. His contemporaries used to say that Lasker used a "psychological" approach to the game, and even that he sometimes deliberately played inferior moves to confuse opponents. Recent analysis, however, indicates that he was ahead of his time and used a more flexible approach than his contemporaries, which mystified many of them. Lasker knew contemporary analyses of openings well but disagreed with many of them. He published chess magazines and five chess books, but later players and commentators found it difficult to draw lessons from his methods. Lasker made contributions to the development of other games. He wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Chess Championship 1921
The 1921 World Chess Championship was played between José Raúl Capablanca and Emanuel Lasker. It was played in Capablanca's native Havana from March 18 to April 28. Capablanca won the match by a score of 9-5 (4 wins, 0 losses, 10 draws) to become the third World Chess Champion. Background Partly due to World War I, negotiations for this match took nearly 10 years. Lasker had been the World Champion since 1894, and had successfully defended his world title five times, most recently in 1910. In 1911, 22-year-old Capablanca won the San Sebastián chess tournament ahead of most of the world's leading players apart from Lasker. Later that year he challenged Lasker to a match for the world title. Lasker was unwilling to play the traditional first-to-win-ten-games-type of match in the semi-tropical conditions of Havana, especially as drawn games were becoming more frequent and the match might last for over six months. He therefore made a counter-proposal: if neither player had a lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Candidates Tournament
The Candidates Tournament (or in some periods Candidates Matches) is a chess tournament organized by FIDE, chess's international governing body, since 1950, as the final contest to determine the challenger for the World Chess Championship. The winner of the Candidates earns the right to a match for the World Championship against the incumbent world champion. Before 1993 it was contested as a triennial tournament; almost always held every third year from 1950 to 1992 inclusive. After the split of the World Championship in the early 1990s, the cycles were disrupted, even after the reunification of the titles in 2006. Since 2013 it has settled into a 2-year cycle: qualification for Candidates during the odd numbered year, Candidates played early in the even numbered year, and the World Championship match played late in the even numbered year. The latter half of the 2020 Candidates Tournament was suspended due to the COVID-19 pandemic and was only played in April 2021.
