According to H. J. R. Murray, the giraffe appears as a (1,4) leaper in Grant Acedrex; however, other sources describe a (2,3) movement pattern, similar to the zebra. [2]
Baroque chess is a chess variant invented in 1962 by Robert Abbott. In 1963, at the suggestion of his publisher, he changed the name to Ultima, by which name it is also known. Abbott later considered his invention flawed and suggested amendments to the rules, but these suggestions have been substantially ignored by the gaming community, which continues to play by the 1962 rules. Since the rules for Baroque were first laid down in 1962, some regional variation has arisen, causing the game to diverge from Ultima.
A chess piece, or chessman, is a game piece that is placed on a chessboard to play the game of chess. It can be either white or black, and it can be one of six types: king, queen, rook, bishop, knight, or pawn.
The knight is a piece in the game of chess, represented by a horse's head and neck. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-files, each located between a rook and a bishop.
Chaturanga is an ancient Indian strategy board game. While there is some uncertainty, the prevailing view among chess historians is that it is the common ancestor of the board games chess, xiangqi (Chinese), janggi (Korean), shogi (Japanese), sittuyin (Burmese), makruk (Thai), and modern Indian chess.
A fairy chess piece, variant chess piece, unorthodox chess piece, or heterodox chess piece is a chess piece not used in conventional chess but incorporated into certain chess variants and some chess problems. Compared to conventional pieces, fairy pieces vary mostly in the way they move, but they may also follow special rules for capturing, promotions, etc. Because of the distributed and uncoordinated nature of unorthodox chess development, the same piece can have different names, and different pieces can have the same name in various contexts. Most are symbolised as inverted or rotated icons of the standard pieces in diagrams, and the meanings of these "wildcards" must be defined in each context separately. Pieces invented for use in chess variants rather than problems sometimes instead have special icons designed for them, but with some exceptions, many of these are not used beyond the individual games for which they were invented.
Sittuyin, also known as Burmese chess, is a strategy board game created in Myanmar. It is a direct offspring of the Indian game of chaturanga, which arrived in Myanmar in the 8th century thus it is part of the same family of games such as chess, and shogi. Sit is the modern Burmese word for "army" or "war"; the word sittuyin can be translated as "representation of the four characteristics of army"—chariot, elephant, cavalry and infantry.
Tamerlane chess is a medieval chess variant. Like modern chess, it is derived from shatranj. It was developed in Central Asia during the reign of Emperor Timur, and its invention is also attributed to him. Because Tamerlane chess is a larger variant of chaturanga, it is also called Shatranj Al-Kabir, as opposed to Shatranj as-saghir. Although the game is similar to modern chess, it is distinctive in that there are varieties of pawn, each of which promotes in its own way.
The longest uncrossedknight's path is a mathematical problem involving a knight on the standard 8×8 chessboard or, more generally, on a square n×n board. The problem is to find the longest path the knight can take on the given board, such that the path does not intersect itself. A further distinction can be made between a closed path, which ends on the same field as where it begins, and an open path, which ends on a different field from where it begins.
Hexagonal chess is a group of chess variants played on boards composed of hexagon cells. The best known is Gliński's variant, played on a symmetric 91-cell hexagonal board.
Camelot is a strategy board game for two players. It was invented by George S. Parker late in the 19th century, and was one of the first games published by Parker Brothers, originally under the name Chivalry.
Omega Chess is a commercial chess variant designed and released in 1992 by Daniel MacDonald. The game is played on a 10×10 board with four extra squares, each added diagonally adjacent to the corner squares. The game is laid out like standard chess with the addition of a champion in each corner of the 10×10 board and a wizard in each new added corner square.
The wazir or vazir is a fairy chess piece that may move a single square vertically or horizontally. In notation, it is given the symbol W. In this article, the wazir is represented by an inverted rook.
Masonic chess is a chess variant invented by George R. Dekle Sr. in 1983. The game is played on a modified chessboard whereby even-numbered ranks are indented to the right—resembling masonry brickwork. The moves of the pieces are adapted to the new geometry; in other respects the game is the same as chess.
Cross chess is a chess variant invented by George R. Dekle Sr. in 1982. The game is played on a board comprising 61 cross-shaped cells, with players each having an extra rook, knight, and pawn in addition to the standard number of chess pieces. Pieces move in the context of a gameboard with hexagonal cells, but Cross chess has its own definition of ranks and diagonals.
Quatrochess is a chess variant for four players invented by George R. Dekle Sr. in 1986. It is played on a square 14×14 board that excludes the four central squares. Each player controls a standard set of sixteen chess pieces, and additionally nine fairy pieces. The game can be played in partnership or all-versus-all.
Congo is a chess variant invented by Demian Freeling in 1982 when he was nearly 8 years old. His father encouraged him to design a variant using a 7×7 gameboard. Demian was already familiar with chess and xiangqi, and the result blends some features from both. Congo became the second-most popular chess variant at the Fanaat games club in Enschede, the Netherlands.
The camel or long knight is a fairy chess piece with an elongated knight move. It can jump three squares horizontally and one square vertically or three squares vertically and one square horizontally, regardless of intervening pieces. Therefore, it is a (1,3)-leaper.
The zebra is a fairy chess piece that moves like a stretched knight. It jumps three squares horizontally and two squares vertically or three squares vertically and two squares horizontally, regardless of intervening pieces; thus, it is a (2,3)-leaper. A lame zebra, which moves one step orthogonally and then two steps diagonally outwards and can be blocked by intervening pieces, appears as the elephant in janggi.
Grant Acedrex is a medieval chess variant dating back to the time of King Alfonso X of Castile. It appears in the Libro de los Juegos of 1283.
5D Chess with Multiverse Time Travel is a 2020 chess variant video game released for Microsoft Windows, macOS, and Linux by American studio Thunkspace. Its titular mechanic, multiverse time travel, allows pieces to travel through time and between timelines in a similar way to how they move through ranks and files.
