Andernach Chess
Andernach chess is a chess variant in which a piece making a capture (except kings) changes colour. For instance, if a white bishop on a2 were to capture a black knight on g8, the result would be a black bishop on g8. Non-capturing moves are played as in orthodox chess. If a pawn captures on eighth rank, it is promoted first and then changes colour. The game was named after the German town of Andernach, which is the site of annual meetings of fairy chess enthusiasts. It was during the 1993 meeting there that Andernach chess was introduced with a chess problem composing tournament for Andernach problems. It has since become a popular variant in problem composition, though it has not yet become popular as a game-playing variant. Example problem An example Andernach chess problem is shown in the diagram. The task is to find a proof game, which would last three moves and lead to the position shown. The solution is: :1. Nf3 Nc6 2. Ne5 Nxe5(=wN) The black knight turns into a white k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Variant
A chess variant is a game related to, derived from, or inspired by chess. Such variants can differ from chess in many different ways. "International" or "Western" chess itself is one of a family of games which have related origins and could be considered variants of each other. Chess developed from ''chaturanga'', from which other members of this family, such as ''makruk, ouk chatrang'', ''shatranj'', Tamerlane chess, ''shogi'', and ''xiangqi'' also evolved. Many chess variants are designed to be played with the equipment of regular chess. Most variants have a similar public-domain status as their parent game, but some have been made into commercial proprietary games. Just as in traditional chess, chess variants can be played over the board, Correspondence chess, by correspondence, or computer chess, by computer. Some internet chess servers facilitate the play of some variants in addition to orthodox chess. In the context of chess problems, chess variants are called heterodox che ...

Queen (chess)
The queen (♕, ♛) is the most powerful piece in the game of chess. It can move any number of squares vertically, horizontally or , combining the powers of the rook and bishop. Each player starts the game with one queen, placed in the middle of the first next to the king. Because the queen is the strongest piece, a pawn is promoted to a queen in the vast majority of cases; if a pawn is promoted to a piece other than a queen, it is an underpromotion. The predecessor to the queen is the '' ferz'', a weak piece only able to move or capture one step diagonally, originating from the Persian game of shatranj. The queen acquired its modern move in Spain in the 15th century. Placement and movement The white queen starts on d1, while the black queen starts on d8. With the chessboard oriented correctly, the white queen starts on a white square and the black queen starts on a black square—thus the mnemonics "queen gets her color", "queen on er wncolor", or "the dress uee ...

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 ...

The Chess Variant Pages
''The Chess Variant Pages'' is a non-commercial website devoted to chess variants. It was created by Hans Bodlaender in 1995. The site is "run by hobbyists for hobbyists" and is "the most wide-ranging and authoritative web site on chess variants". The site contains a large compilation of games with published rules. The aims of the site are to educate readers about chess variants, encourage gameplay, and provide a place for free discussion. The site has featured game competitions as well as variant design competitions, and provides facilities for publishing documents. Numerous files are available for playing variants using the Zillions of Games proprietary software engine. The site also features The Game Courier software developed by Fergus Duniho which can be used to play almost any variant. There is also an extensive encyclopedia of fairy chess piece A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventio ...

Martian Chess
Martian Chess is an abstract strategy game for two or four players invented by Andrew Looney in 1999. It is played with Icehouse pyramids on a chessboard. To play with a number of players other than two or four, a non-Euclidean surface can be tiled to produce a board of the required size, allowing up to six players. In his review in ''Abstract Games Magazine'', Kerry Handscomb stated: The first thing to note about Martian Chess is that it is not a chess-type game at all. Instead, the objective is to accumulate points by capturing pieces. Martian Chess is ..an original game with novel tactics and strategy. In 1996, Looney had invented Monochrome Chess, a similar two-player game that uses regular chess pieces where the half of the board determined who controlled a piece. While the king is not royal, the king and rook can castle. History Martian Chess was one of four games in the '' Icehouse: The Martian Chess Set'' released by Looney Labs in 1999. The set was Looney Labs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibet
Tibet (; ''Böd''; ), or Greater Tibet, is a region in the western part of East Asia, covering much of the Tibetan Plateau and spanning about . It is the homeland of the Tibetan people. Also resident on the plateau are other ethnic groups such as Mongols, Monpa people, Monpa, Tamang people, Tamang, Qiang people, Qiang, Sherpa people, Sherpa, Lhoba people, Lhoba, and since the 20th century Han Chinese and Hui people, Hui. Tibet is the highest region on Earth, with an average elevation of . Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth's highest mountain, rising above sea level. The Tibetan Empire emerged in the 7th century. At its height in the 9th century, the Tibetan Empire extended far beyond the Tibetan Plateau, from the Tarim Basin and Pamirs in the west, to Yunnan and Bengal in the southeast. It then divided into a variety of territories. The bulk of western and central Tibet (Ü-Tsang) was often at least nominally unified under a ser ...

King (chess)
The king (♔, ♚) is the most important chess piece, piece in the game of chess. It may move to any adjoining square; it may also perform, in tandem with the Rook (chess), rook, a special move called ''castling''. If a player's king is threatened with capture, it is said to be ''in Check (chess), check'', and the player must remove or evade the threat of immediately, such as by moving it away from the attacked square. If this cannot be done, the king is said to be in checkmate, resulting in a loss for that player. A player cannot make any move that places their own king in check. Despite this, the king can become a strong offensive piece in the Chess endgame, endgame or, rarely, the Chess middlegame, middlegame. In Algebraic notation (chess), algebraic notation, the king is abbreviated by the letter ''K'' among English speakers. The white king starts the game on e1; the black king starts on e8. Unlike all other pieces, each player can have only one king, and the kings are never ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortest 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] |
