Fairy-Max
Fairy-Max is a free and open source chess engine which can play orthodox chess as well as chess variants. Among its features is the ability of users to define and use their own custom variant chess pieces for use in games. Fairy-Max was derived from micro-Max (also developed by H.G. Muller), one of the smallest programs to play complete FIDE chess. Therefore, Fairy-Max versioning started with version number 4.8, the version of micro-Max used. Description The Fairy-Max module is a chess engine only, but is packaged with WinBoard/XBoard, which serves as the graphical user interface. Users can play against the Fairy-Max engine, or play the engine against other engines. It can also be set up to play two armies against each other, both using the Fairy-Max engine, for the purpose of analyzing chess moves, chess variants, or variant chess pieces. Capabilities Besides classical FIDE chess, Fairy-Max is provided with a large selection of pre-defined games using fairy chess pi ...

XBoard
XBoard is a graphical user interface chessboard for chess engines under the X Window System. It is developed and maintained as free software by the GNU project. WinBoard is a port of XBoard to run natively on Microsoft Windows. Overview Originally developed by Tim Mann as a front end for the GNU Chess engine, XBoard eventually came to be described as a graphical user interface for XBoard engines. It also acts as a client for Internet Chess Servers, and e-mail chess, and can allow the user to play through saved games. XBoard/WinBoard remain updated, and the Chess Engine Communication Protocol has been extended to meet the needs of modern engines (which have features such as hash tables, multi-processing and end-game tables, which could not be controlled through the old protocol). XBoard/WinBoard also fully support engines that play chess variants, such as Fairy-Max. This means the GUI is able to display a wide range of variants such as xiangqi (Chinese chess), shogi (Japane ...

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 '' 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 ...

List Of Chess Software
Chess software comes in different forms. A chess playing program provides a graphical chessboard on which one can play a chess game against a computer. Such programs are available for personal computers, video game consoles, smartphones/ tablet computers or mainframes/ supercomputers. A chess engine generates moves, but is accessed via a command-line interface with no graphics. A dedicated chess computer has been purpose built solely to play chess. A graphical user interface (GUI) allows one to import and load an engine, and play against it. A chess database allows one to import, edit, and analyze a large archive of past games. Chess-playing programs for personal computers Chess engines This list contains only chess engines for which Wikipedia articles exist yet and therefore is very incomplete. It does not reflect or imply current or historic play strength as this characteristic in itself usually does not warrant an entry on Wikipedia. Chess graphical user interfaces ...

Seirawan Chess
Capablanca chess (or Capablanca's chess) is a chess variant invented in the 1920s by World Chess Champion José Raúl Capablanca. It incorporates two new pieces and is played on a 10×8 board. Capablanca believed that chess would be played out in a few decades (meaning games between grandmasters would always end in draws). This threat of "draw death" for chess was his main motivation for creating a more complex version of the game. * The archbishop combines powers of a bishop and a knight. * The chancellor combines powers of a rook and a knight. The new pieces allow new strategies and possibilities that change the game. For example, the archbishop by itself can checkmate a lone king in the corner (when placed diagonally with one square in between). Setup and rules Capablanca proposed two opening setups for Capablanca chess. His final revision placed the archbishop between the and ; the chancellor between the and . The king moves three squares when castling instead of ...

ChessV
ChessV (short for Chess Variants) is a free computer program designed to play many chess variants. ''ChessV'' is an open-source, universal chess variant program with a graphical user-interface, sophisticated AI, support for opening books and other features of traditional chess programs. The developer of this program, Gregory Strong, has been adding more variants with each release of ''ChessV''. Over 100 chess variants are supported, including the developer's few own variants and other exotic variants, and can be programmed to play additional variants. ''ChessV'' is designed to be able to play any game that is reasonably similar to chess. ''ChessV'' is one of only a few such programs that exist. The source code of this program is freely available for download as well as the executable program. As of ChessV 0.93, it is possible to customize the variants it supports. Of all chess variants supported, two of the most-played variants are probably Fischer Random Chess and Grand Chess. ...

Chess Engine
In computer chess, a chess engine is a computer program that analyzes chess or chess variant positions, and generates a move or list of moves that it regards as strongest. A chess engine is usually a back end with a command-line interface with no graphics or windowing. Engines are usually used with a front end, a windowed graphical user interface such as Chessbase or WinBoard that the user can interact with via a keyboard, mouse or touchscreen. This allows the user to play against multiple engines without learning a new user interface for each, and allows different engines to play against each other. Many chess engines are now available for mobile phones and tablets, making them even more accessible. History The meaning of the term "chess engine" has evolved over time. In 1986, Linda and Tony Scherzer entered their program Bebe into the 4th World Computer Chess Championship, running it on "Chess Engine," their brand name for the chess computer hardware made, and marke ...

King Of The Hill (chess)
This is a list of chess variants. Many thousands of variants exist. The 2007 catalogue ''The Encyclopedia of Chess Variants'' estimates that there are well over 2,000, and many more were considered too trivial for inclusion in the catalogue. Chess-derived games These chess variants are derived from chess by changing the board, board setup, pieces, or rules. Standard rules and standard piece types Many variants employ standard chess rules and mechanics, but vary the starting position of the pieces or number of pieces. Standard rules, standard piece types, variant board In these variants, the same pieces and rules as in chess are used, but the board is different; It can be smaller or larger, the shape of either the board or individual spaces can be non-square or modular, or it can even be extra-dimensional or Bounded set, unbounded. The movement of pieces in some variants is modified in concurrence with the geometry of the gameboard. * Active Chess: Played on a 9×8 boar ...

Courier Chess
Courier chess is a chess variant that dates from the 12th century and was popular for at least 600 years. It was a part of the slow evolution towards modern chess from Medieval Chess. Medieval rules Courier chess is played on an 8x12 board (i.e., 8 ranks by 12 files). Literary and artistic evidence indicate that the board was always checkered but that there was no consistency as to which squares were light and which squares were dark. The more frequent pattern is that the square at the bottom right corner was light, just as in modern chess. The winning objective is the same as western chess: to checkmate the opponent's king. The stalemate rule is unknown; the subject was unsettled in Germany late into the nineteenth century. * The kings start on squares of their own color, at f1 and f8. Just as in western chess, the king may move to any adjoining square, and a player cannot end their turn in check. There is no castling. * Next to the king, on e1 and e8, stands the sage or ...

Elo Rating System
The Elo rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor. The Elo system was invented as an improved chess-rating system over the previously used Harkness system, but is also used as a rating system in association football, American football, baseball, basketball, pool, table tennis, and various board games and esports. The difference in the ratings between two players serves as a predictor of the outcome of a match. Two players with equal ratings who play against each other are expected to score an equal number of wins. A player whose rating is 100 points greater than their opponent's is expected to score 64%; if the difference is 200 points, then the expected score for the stronger player is 76%. A player's Elo rating is represented by a number which may change depending on the outcome of rated games played. After every game, the winn ...

Berolina Chess
Berolina chess is a chess variant using a popular fairy chess piece called the Berolina pawn (also known as ''Berlin pawn'', ''Anti-pawn'', or simply ''Berolina''). The Berolina pawn was invented by Edmund Nebermann in 1926''Funkschach'', August 1926 and has found frequent use in chess problems. Berolina chess follows the same rules as standard chess, except that all 16 pawns are replaced by equivalently-colored Berolina pawns. Berolina pawn The Berolina pawn moves, without capturing, one square diagonally forward. It captures one square straight forward. (Thus, it is the converse of a standard chess pawn, which moves straight forward and captures diagonally forward.) The Berolina has the option to move two squares diagonally forward on its first move. Capturing ''en passant'' is possible as well: a Berolina pawn may capture a horizontally adjacent enemy Berolina pawn that has just made a two-square move as if the latter had only moved one square. Like the orthodox pawn, the ...
