Minichess
Minichess is a family of chess variants played with regular chess pieces and standard rules, but on a smaller board. The motivation for these variants is to make the game simpler and shorter than standard chess. The first chess-like game implemented on a computer was the 6×6 chess variant Los Alamos chess. The low memory capacity of early computers meant that a reduced board size and a smaller number of pieces were required for the game to be implementable on a computer. 3×3 and 3×4 boards Chess on a 3×3 board does not have any clearly defined starting position. However, it is a solved game: the outcome of every possible position is known. The best move for each side is known as well. The game was solved independently by Aloril in 2001 and by Kirill Kryukov in 2004. The solution by Kryukov is more complete, since it allows pawns to be placed everywhere, not only on the second row as by Aloril. The longest checkmate on a 3×3 board takes 16 moves. The number of legal position ... [...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 ''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] |
Los Alamos Chess
Los Alamos chess (or anti- clerical chessAnderson (1986), p. 105) is a chess variant played on a 6×6 board without bishops. This was the first chess-like game played by a computer program. This program was written at Los Alamos Scientific Laboratory by Paul Stein and Mark Wells for the computerPritchard (1994), p. 175 in 1956. The reduction of the board size and the number of pieces from standard chess was due to the very limited capacity of computers at the time. Game rules The starting position is illustrated. All rules are as in chess except: * There is no pawn double-step move, nor is there the ''en passant'' capture; * Pawns may not be promoted to bishops; * There is no castling. Los Alamos trials The computer played three games. The first it played against itself. The second one was against a strong human player, who played without a queen. The human player won. In the third game, MANIAC I played against a laboratory assistant who had been taught the rules o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solved Game
A solved game is a game whose outcome (win, lose or draw) can be correctly predicted from any position, assuming that both players play perfectly. This concept is usually applied to abstract strategy games, and especially to games with full information and no element of chance; solving such a game may use combinatorial game theory and/or computer assistance. Overview A two-player game can be solved on several levels: ;Ultra-weak : Prove whether the first player will win, lose or draw from the initial position, given perfect play on both sides. This can be a non-constructive proof (possibly involving a strategy-stealing argument) that need not actually determine any moves of the perfect play. ;Weak : Provide an algorithm that secures a win for one player, or a draw for either, against any possible moves by the opponent, from the beginning of the game. ;Strong : Provide an algorithm that can produce perfect moves from any position, even if mistakes have already been made on one or b ...

Dōbutsu Shōgi
is a small shogi variant for young children. It was invented by :Professional shogi player#Women's professionals, women's professional shogi player , partially to attract young girls to the game. It is played on a 3×4 board and generally follows the rules of standard shogi, including Shogi#Drops, drops, except that pieces can only move one square at a time, and the king reaching the enemy camp as an additional way to win the game. The pieces are square, like children's blocks, have cartoon figures of the relevant animal rather than kanji to identify them, and often have dots on the sides and corners of the directions the pieces can move. The game has been marketed overseas as "Let's Catch the Lion!"

Tic Tac Chec
A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups.American Psychiatric Association (2000)DSM-IV-TR: Tourette's Disorder.''Diagnostic and Statistical Manual of Mental Disorders'', 4th ed., text revision (DSM-IV-TR), . Available at BehaveNet.com Retrieved on August 10, 2009. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing. Tics must be distinguished from movements of disorders such as chorea, dystonia and myoclonus; the compulsions of obsessive–compulsive disorder (OCD) and seizure activity; and movements exhibited in stereotypic movement disorder or among autistic people (also known as stimming). Classification Tics are classified as either motor or phonic, and simple or complex. Motor or phonic Motor tics are movement-based tics affecting discrete muscle groups. Phonic tics are involuntary sounds prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnus Kø
Magnus, meaning "Great" in Latin, was used as cognomen of Gnaeus Pompeius Magnus in the first century BC. The best-known use of the name during the Roman Empire is for the fourth-century Western Roman Emperor Magnus Maximus. The name gained wider popularity in the Middle Ages among various European people who lived in Stykkishólmur in their royal houses, being introduced to them upon being converted to the Latin-speaking Catholic Christianity. This was especially the case with Scandinavian royalty and nobility. As a Scandinavian forename, it was extracted from the Frankish ruler Charlemagne's Latin name "Carolus Magnus" and re-analyzed as Old Norse ''magn-hús'' = "power house". People Given name Kings of Hungary * Géza I (1074–1077), also known by his baptismal name Magnus. Kings of Denmark * Magnus the Good (1042–1047), also Magnus I of Norway King of Livonia * Magnus, Duke of Holstein (1540–1583) King of Mann and the Isles * Magnús Óláfsson (died 1265) Ki ...

Microshogi
Microshogi (五分摩訶将棋 ''gofun maka shōgi'' "5-minute (scarlet) poppy chess") is a modern variant of shogi (Japanese chess), with very different rules for promotion, and demotion. Kerry Handscomb of NOSTNOST (kNights of the Square Table), a (now defunct) correspondence game club formed in 1960 by Bob Lauzon and Jim France, enjoyed several hundred active members. gave it this English name. Although not confirmed, he credits its invention to the late Oyama Yasuharu, a top level shogi player. The game was invented before 1982. Equipment Two players play on a board ruled into a grid of 5 ranks (rows) by 4 files (columns). The squares are undifferentiated by marking or color. Each player has a set of 5 wedge-shaped pieces. The pieces are of slightly different sizes. From largest to smallest (or most to least powerful) they are: *1 king *1 bishop *1 gold general *1 silver general *1 pawn Game rules The game is identical to standard shogi with the following exceptions.

Whale Shogi
Whale Shogi (鯨将棋 ''kujira shōgi)'' is a modern variant of shogi (Japanese chess). It is not, however, Japanese: it was invented by R. Wayne Schmittberger of the United States in 1981. The game is similar to Judkins shogi, but with more pieces, and the pieces are named after types of whale. Game rules Objective The objective of the game is to capture your opponent's white whale. Game equipment Two players, Black and White (or 先手 ''sente'' and 後手 ''gote),'' play on a board ruled into a grid of 6 ranks (rows) by 6 files (columns). The squares are undifferentiated by marking or color. Each player has a set of 12 wedge-shaped pieces, of slightly different sizes. From largest to smallest (most to least powerful) they are: *1 white whale (W) *1 porpoise (P) *1 humpback (H) *1 gray whale (G) *1 narwhal (N) *1 blue whale (B) *6 dolphins (D) Each piece has its initial written on its face. On the reverse side of the porpoise is another letter (K for 'killer whale'), often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexapawn
Hexapawn is a deterministic two-player game invented by Martin Gardner. It is played on a rectangular board of variable size, for example on a 3×3 board or on a regular chessboard. On a board of size ''n''×''m'', each player begins with ''m'' pawns, one for each square in the row closest to them. The goal of each player is to either advance a pawn to the opposite end of the board or leave the other player with no legal moves. Hexapawn on the 3×3 board is a solved game; with perfect play, White will always lose in 3 moves (1.b2 axb2 2.cxb2 c2 3.a2 c1#). Indeed, Gardner specifically constructed it as a game with a small game tree in order to demonstrate how it could be played by a heuristic AI implemented by a mechanical computer based on Donald Michie's Matchbox Educable Noughts and Crosses Engine. A variant of this game is octopawn, which is played on a 4×4 board with 4 pawns on each side. It is a forced win for White. Rules As in chess, a pawn may be moved in two differe ...

Chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

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 ...
