Rook And Bishop Versus Rook Endgame
The rook and bishop versus rook endgame is a chess endgame where one player has just a king, a rook, and a bishop, and the other player has just a king and a rook. This combination of is one of the most common pawnless chess endgames. It is generally a theoretical draw, but the rook and bishop have good winning chances in practice because the defense is difficult. Ulf Andersson won the position twice within a year, once against a grandmaster and once against a candidate master; and grandmaster Keith Arkell has won it 18 times out of 18.In 2007 Giddens (page 78) reported 16 out of 16. In positions that have a forced win, up to 59 moves are required. Tony Kosten has seen the endgame many times in master games, with the stronger side almost always winning. Pal Benko called this the "headache ending." Being a five-piece endgame, the rook and bishop versus rook endgame has been fully analysed using computers. Endgame tablebases show that 40.1% of the legal positions with this material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fifty-move Rule
The fifty-move rule in chess states that a player can claim a draw if no has been made and no pawn has been moved in the last fifty moves (for this purpose a "move" consists of a player completing a turn followed by the opponent completing a turn). The purpose of this rule is to prevent a player with no chance of winning from obstinately continuing to play indefinitely or seeking to win by tiring the opponent. Chess positions with only a few pieces can be " solved", that is, the outcome of best play for both sides can be determined by exhaustive analysis; and if the outcome is a win for one side or the other (rather than a draw), it is of interest to know whether the defending side can hold out long enough to invoke the fifty-move rule. The simplest common endings, called the basic checkmates, such as king and queen versus king, can all be won in well under 50 moves. However, in the 20th century it was discovered that certain endgame positions are winnable but require more than 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Kll45
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, two bi ...

International Master
FIDE titles are awarded by the international chess governing body FIDE (''Fédération Internationale des Échecs'') for outstanding performance. The highest such title is Grandmaster (GM). Titles generally require a combination of Elo rating and norms (performance benchmarks in competitions including other titled players). Once awarded, titles are held for life except in cases of fraud or cheating. Open titles may be earned by all players, while women's titles are restricted to female players. Many strong female players hold both open and women's titles. FIDE also awards titles for arbiters, organizers and trainers. Titles for correspondence chess, chess problem composition and chess problem solving are no longer administered by FIDE. A chess title, usually in an abbreviated form, may be used as an honorific. For example, Magnus Carlsen may be styled as "GM Magnus Carlsen". History The term "master" for a strong chess player was initially used informally. From the late 19th c ...

Chess Tournament
A chess tournament is a series of chess games played competitively to determine a winning individual or team. Since the first international chess tournament in London, 1851, chess tournaments have become the standard form of chess competition among serious players. Today, the most recognized chess tournaments for individual competition include the Linares chess tournament (now defunct) and the Tata Steel chess tournament. The largest team chess tournament is the Chess Olympiad, in which players compete for their country's team in the same fashion as the Olympic Games. Since the 1960s, chess computers have occasionally entered human tournaments, but this is no longer common. Most chess tournaments are organized and ruled according to the World Chess Federation (FIDE) handbook, which offers guidelines and regulations for conducting tournaments. Chess tournaments are mainly held in either round-robin style, Swiss system style or elimination style to determine a winning party. ...

André Chéron
André Chéron (September 25, 1895 – September 12, 1980) was a French chess player, endgame theorist, and a composer of endgame studies. He was named a FIDE International Master of Chess Composition in 1959, the first year the title was awarded. Chéron was the French champion three times (1926, 1927, and 1929) and played on the French team at the .

Josef Kling
Josef Kling (19 March 1811 – 1 December 1876), also found in English-language sources as Joseph Kling, was a German chess master and chess composer. He has been called "a pioneer of the modern style of chess." Although Kling was an expert on endgames and problems, he rarely played competitively. Kling wrote several studies of the game. He co-edited the problem book ''Chess Studies'' (1851) with Bernhard Horwitz. From January 1851 to December 1853, the pair also co-edited the weekly journal ''The Chess Player,'' also known as ''The New Chess Player''. As co-authors, they made notable contributions to endgame theory, and are thought to have originated the term "cook" in reference to "an unsound chess problem having two solutions." Kling began as a teacher of instrumental music, but in the early 1850s found himself with few students. He emigrated from Mainz, Germany, to England, where in 1852 he opened a coffee house with chess rooms, located at 454 New Oxford Street in London. ...

Tassilo Von Heydebrand Und Der Lasa
Tassilo, Baron von Heydebrand und der Lasa (known in English as Baron von der Lasa, 17 October 1818, Berlin – 27 July 1899, Storchnest near Lissa, Greater Poland, then German Empire) was a German chess master, chess historian and theoretician of the nineteenth century, a member of the Berlin Chess Club and a founder of the Berlin Chess School (the Berlin Pleiades). His name is usually abbreviated as "von der Lasa", as this is how he signed his letters. However both contemporary and more recent writers have used other abbreviations, such as "von Heydebrandt" (which is a misspelling) and "Der Lasa". The Prussian King (later Emperor) William I made a joke out of the confusion by saying, "Good morning, dear Heydebrand. What is von der Lasa doing?" Von der Lasa was born 17 October 1818 in Berlin. He studied law in Bonn and Berlin. From 1845 he was a diplomat in the service of Prussia. His career took him to Stockholm, Copenhagen, and Rio de Janeiro, among other places. He ...

József Szén
József Szén (9 July 1805, Pest, Hungary – 13 January 1857) was a Hungarian chess master. He obtained a law degree, and later became a civil servant for the city of Pest, which later merged with the city of Buda (on the opposite bank of the Danube River) in 1873 to form present-day Budapest. He often played in the ''Café Worm'' of Pest, playing with any opponent for a stake of 20 Kreuzers. Very strong in the endgame, he was given the nickname of ''the Hungarian Philidor''. He discovered and described the Szen position, in the endgame of rook and bishop against rook, as a drawing method for the weaker side (see below). This work has stood up to subsequent analysis. From 1836 to 1839, Szen travelled extensively throughout much of Europe, including France, Germany and England, playing chess wherever he went. In 1836 Szén played a match in Paris with Louis-Charles Mahé de La Bourdonnais, then considered the strongest player in the world, in which de La Bourdonnais gave him o ...

John Cochrane (chess Player)
John Cochrane (4 February 1798 – 2 March 1878) was a Scottish chess master and lawyer. After serving in the Royal Navy Cochrane chose to become a barrister. While studying law, he became a very strong chess player and published a book on the game, which included the Cochrane variation of the Salvio Gambit, a main line of the King's Gambit. Around this time he played against the Frenchmen Deschapelles and Labourdonnais, who were acknowledged to be Europe's strongest players at the time. After a long tour of duty in India, he returned to the UK and beat everyone except Howard Staunton, whom he then helped to prepare for his victorious match against the Frenchman Saint-Amant, which established Staunton as the world's leading player. Cochrane returned to India, where he became known as the "Father of the Calcutta Bar" (association of barristers) and a leading member of the Calcutta Chess Club; the Club and Cochrane personally both made significant financial contributions to the f ...

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, notably ...
