Chess Composition
A chess problem, also called a chess composition, is a Chess puzzle, puzzle created by the composer using chess pieces on a chessboard, which presents the solver with a particular task. For instance, a position may be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defence. A chess problem fundamentally differs from play in that the latter involves a struggle between Black and White, whereas the former involves a competition between the composer and the solver. Most positions which occur in a chess problem are unrealistic in the sense that they are very unlikely to occur in over-the-board play. There is a substantial amount of Glossary of chess problems, specialized jargon used in connection with chess problems. Definition The term chess problem is not sharply defined: there is no clear demarcation between chess compositions on the one hand and puzzle or Chess tactics, tactical exercises on the other.

En Passant
In chess, ''en passant'' (, "in passing") describes the capture by a Pawn (chess), pawn of an enemy pawn on the same and an adjacent that has just made an initial two-square advance. This is a special case in the rules of chess. The capturing pawn moves to the square that the enemy pawn passed over, as if the enemy pawn had advanced only one square. The rule ensures that a pawn cannot use its two-square move to safely skip past an enemy pawn. Capturing ''en passant'' is permitted only on the turn immediately after the two-square advance; it cannot be done on a later turn. The capturing move is sometimes Chess notation, notated by appending the abbreviation e.p. Rules The conditions for a pawn to capture an enemy pawn ''en passant'' are as follows: * the enemy pawn Rules of chess#Basic moves, advanced two squares on the previous turn; * the capturing pawn attacks the square that the enemy pawn passed over. If these conditions are met, the capturing pawn can move diagonal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vladimir Nabokov
Vladimir Vladimirovich Nabokov ( ; 2 July 1977), also known by the pen name Vladimir Sirin (), was a Russian and American novelist, poet, translator, and entomologist. Born in Imperial Russia in 1899, Nabokov wrote his first nine novels in Russian (1926–1938) while living in Berlin, where he met his wife, Véra Nabokov. He achieved international acclaim and prominence after moving to the United States, where he began writing in English. Trilingual in Russian, English, and French, Nabokov became a U.S. citizen in 1945 and lived mostly on the East Coast before returning to Europe in 1961, where he settled in Montreux, Switzerland. From 1948 to 1959, Nabokov was a professor of Russian literature at Cornell University. His 1955 novel ''Lolita'' ranked fourth on Modern Library's list of the Modern Library 100 Best Novels, 100 best 20th-century novels in 1998 and is considered one of the greatest works of 20th-century literature. Nabokov's ''Pale Fire'', published in 1962, ranked 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Aesthetics
Chess aesthetics or beauty in chess is the aesthetic appreciation of chess games and problems, by both players and composers. This is evident, for example, in awarded to some games in certain Chess tournament, tournaments and also in the world of chess composition. There are many books published featuring chess problems or puzzles that emphasize its aesthetic aspect. One of the earliest is from the 9th century AD. Aesthetics in chess can be both a source of pleasure for humans and also instruction, as compositions or games featuring it typically illustrate original ideas or new instantiations of old ones. A good chess problem composer, however, is not necessarily a good player. Factors about a game or move sequence (also referred to as a ''Combination (chess), combination'') that might cause it to be regarded as 'brilliant' by most players include, among other things: expediency, disguise, sacrifice, correctness, preparation, paradox, unity and originality. * ''Expediency'' refe ...

Fairy Chess
Fairy chess is the area of chess composition in which there are some changes to the rules of chess. It may involve changes to the board, pieces, or rules to express an idea or theme impossible in orthodox chess. An altered piece used in fairy chess is known as a fairy chess piece. The term ''fairy chess'' was introduced by Henry Tate in 1914. Thomas R. Dawson (1889–1951), the "father of fairy chess", invented many fairy pieces and new conditions. He was also problem editor of '' Fairy Chess Review'' (1930–1951). Although the term ''fairy chess'' is sometimes used for games, it is more usually applied in the context of problems. Variations on chess intended to create complete, playable games are more typically referred to as ''chess variants''. Types of fairy chess problems Types of changed rules in fairy chess problems include: * ''New stipulations:'' The alterations most used by fairy chess players, like Thomas Dawson, are new stipulations about mate instead of a direc ...

External Links
An internal link is a type of hyperlink on a web page to another page or resource, such as an image or document, on the same website or domain. It is the opposite of an external link, a link that directs a user to content that is outside its domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same web page or to another page of the same website or domain is considered internal. Both internal and external links allow users of the website to navigate to another web page or resource. These definitions become clouded, however, when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a non-secure website. In these cases, links that are "external" by the above definition can conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beauty In Chess Problems
Beauty is commonly described as a feature of objects that makes them pleasurable to perceive. Such objects include landscapes, sunsets, humans and works of art. Beauty, art and taste are the main subjects of aesthetics, one of the fields of study within philosophy. As a positive aesthetic value, it is contrasted with ugliness as its negative counterpart. One difficulty in understanding beauty is that it has both objective and subjective aspects: it is seen as a property of things but also as depending on the emotional response of observers. Because of its subjective side, beauty is said to be "in the eye of the beholder". It has been argued that the ability on the side of the subject needed to perceive and judge beauty, sometimes referred to as the "sense of taste", can be trained and that the verdicts of experts coincide in the long run. This suggests the standards of validity of judgments of beauty are intersubjective, i.e. dependent on a group of judges, rather than fully su ...

Sam Loyd
Samuel Loyd (January 30, 1841 – April 10, 1911) was an American chess player, chess composer, puzzle author, and recreational mathematics, recreational mathematician. Loyd was born in Philadelphia but raised in New York City. As a chess composer, he authored a number of chess problems, often with interesting themes. At his peak, Loyd was one of the best chess players in the US, and he was ranked 15th in the world, according to chessmetrics.com. He played in the strong Paris 1867 chess tournament (won by Ignatz von Kolisch) with little success, placing near the bottom of the field. Following his death, his book ''Cyclopedia of 5000 Puzzles'' was published (1914) by his son, Samuel Loyd Jr. His son, named after his father, dropped the "Jr" from his name and started publishing reprints of his father's puzzles. Loyd (senior) was inducted into the US Chess Hall of Fame in 1987. Reputation Loyd is widely acknowledged as one of America's great puzzle writers and popularizers, ofte ...

Proof Game
A proof game is a type of retrograde analysis chess problem. The solver must construct a game starting from the initial chess position, which ends with a given position (thus proving that that position is reachable) after a specified number of moves. A proof game is called a shortest proof game if no shorter solution exists. In this case the task is simply to construct a shortest possible game ending with the given position. When published, shortest proof games will normally present the solver with a diagram - which is the final position to be reached - and a caption such as "SPG in 9.0". "SPG" here is short for "shortest proof game" and the "9.0" indicates how many moves must be played to reach the position; 9.0 means the position is reached after black's ninth move, 7.5 would mean the position is reached after seven and a half moves (that is, after white's eighth move) and so on. Sometimes the caption may be more verbose, for example "Position after white's seventh move. How did ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retrograde Analysis
In chess problems, retrograde analysis is a technique employed to determine which moves were played leading up to a given position. While this technique is rarely needed for solving ordinary chess problems, there is a whole subgenre of chess problems in which it is an important part; such problems are known as ''retros''. Retros may ask, for example, for a mate in two, but the main puzzle is in explaining the history of the position. This may be important to determine, for example, if castling is disallowed or an ''en passant'' capture is possible. Other problems may ask specific questions relating to the history of the position, such as, "Is the bishop on c1 promoted?". This is essentially a matter of logical reasoning, with high appeal for puzzle enthusiasts. Sometimes it is necessary to determine if a particular position is legal, with "legal" meaning that it could be reached by a series of legal moves, no matter how illogical. Another important branch of retrograde analysi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
