Modern Chess
Modern chess is a chess variant played on a 9×9 board. The game was invented by Gabriel Vicente Maura in 1968. Besides the usual set of chess pieces, each player has a prime minister and an additional pawn: : The prime minister (M) combines powers of a bishop and a knight. The first match was played in Madrid at Escuela de Bellas Artes de San Fernando's cafe on March 18, 1968. The players were Gabriel Vicente Maura himself (White), and Bonifacio Pedraz Cabezas (Black). Game rules The starting setup is as shown. All the standard rules of chess apply, along with the following special rules: * A player can castle either ministerside (notated "0-M-0") or queenside (notated "0-Q-0"); in either case the king slides two squares toward the castling rook. * When reaching the final rank, pawns can promote to one of the usual pieces or to prime minister. Optional rule In response to criticism that bishops are restricted to only one square color, the inventor proposed an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princess (chess)
The princess is a fairy chess piece that can move like a bishop or a knight. It cannot jump over other pieces when moving as a bishop but may do so when moving as a knight. The piece has acquired many names and is frequently called archbishop or cardinal; it may also simply be called the bishop+knight compound. Chess moves in this article use ''A'' as notation for the princess. Movement The princess can move as a bishop or a knight. History and nomenclature The princess is one of the most simply described fairy chess pieces and as such has a long history and has gone by many names. It was first used in Turkish Great Chess, a large medieval variant of chess, where it was called the ''vizir'' (not to be confused with the piece more commonly referred to as the wazir today, which is the (1,0) leaper). It was introduced in the West with Carrera's chess, a chess variant from 1617, where it was called a ''centaur'', and has been used in many chess variants since then. The n ...

Promotion (chess)
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last . The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same . The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn. Promotion to a queen is known as queening; promotion to any other piece is known as underpromotion. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame. Rules When a pawn is promoted, it is removed from the board, and the new piece is placed on the square of promotion. A piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more queens, or three or more rooks, bishops, or kni ...

Chess Variants
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 ''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, by correspondence, or 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 chess or fairy chess. Fairy chess variants tend to be created ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pawn (chess)
The pawn (♙, ♟) is the most numerous and weakest piece in the game of chess. It may move one vacant square directly forward, it may move two vacant squares directly forward on its first move, and it may capture one square diagonally forward. Each player begins a game with eight pawns, one on each square of their second . The white pawns start on a2 through h2; the black pawns start on a7 through h7. Individual pawns are referred to by the on which they stand. For example, one speaks of "White's f-pawn" or "Black's b-pawn". Alternatively, they can be referred to by the piece which stood on that file at the beginning of the game, e.g. "White's king bishop's pawn" or "Black's queen knight's pawn". It is also common to refer to a rook's pawn, meaning any pawn on the a- or h-files, a knight's pawn (on the b- or g-files), a bishop's pawn (on the c- or f-files), a queen's pawn (on the d-file), a king's pawn (on the e-file), and a central pawn (on the d- or e-files).

Rook (chess)
The rook (; ♖, ♜) is a piece in the game of chess. It may move any number of squares horizontally or vertically without jumping, and it may an enemy piece on its path; additionally, it may participate in castling. Each player starts the game with two rooks, one in each corner on their own side of the board. Formerly, the rook (from Persian رخ ''rokh''/''rukh'', meaning "chariot") was alternatively called the tower, marquess, rector, and comes (count or earl). The term "castle" is considered to be informal, incorrect, or old-fashioned. Placement and movement The white rooks start on squares a1 and h1, while the black rooks start on a8 and h8. The rook moves horizontally or vertically, through any number of unoccupied squares (see diagram). The rook cannot jump over pieces. The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play. The rook also participates with the king in a special move called castling, wherein i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castling
Castling is a move in chess. It consists of moving the king two squares toward a rook on the same and then moving the rook to the square that the king passed over. Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece. Castling is the only move in chess in which two pieces are moved at once. Castling with the is called ''kingside castling'', and castling with the is called ''queenside castling''. In both algebraic and descriptive notations, castling kingside is written as 0-0 and castling queenside as 0-0-0. Castling originates from the ''king's leap'', a two-square king move added to European chess between the 14th and 15th centuries, and took on its present form in the 17th century. Local variations in castling rules were common, however, persisting in Italy until the late 19th century. Castling does not ...
