Los Alamos Chess
Los Alamos chess (or anti-clerical chess) 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 computer 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. The computer still needed about 20 minutes between moves. The program was very simple, containing only about 600 instructions. It was mostly a minimax tree search and could look four plies ahead. For scoring the board at the end of the four-ply lookahead, it estimates a score for material and a score for mobility, then adds them. Pseudocode for the chess program is described in Figure 11.4 of Newell, 2019. In 1958, a revised version was written for MANIAC II for full 8×8 chess, though its pseudocode was never published. There is a record of a single game by it, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rules Of Chess
The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player Abstract strategy game, abstract strategy board game. Each player controls sixteen chess piece, pieces of six types on a chessboard. Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's King (chess), king; checkmate occurs when a king is threatened with capture and has no escape. A game can end in various ways besides checkmate: a player can #Resigning, resign, and there are several ways a game can end in a Draw (chess), draw. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from region to region. Today, the standard rules are set by FIDE (Fédération Internationale des Échecs), the international governing body for ches ...

Computer Chess
Computer chess includes both hardware (dedicated computers) and software capable of playing chess. Computer chess provides opportunities for players to practice even in the absence of human opponents, and also provides opportunities for analysis, entertainment and training. Computer chess applications that play at the level of a Chess title, chess grandmaster or higher are available on hardware from supercomputers to Smartphone, smart phones. Standalone chess-playing machines are also available. Stockfish (chess), Stockfish, Leela Chess Zero, GNU Chess, Fruit (software), Fruit, and other free open source applications are available for various platforms. Computer chess applications, whether implemented in hardware or software, use different strategies than humans to choose their moves: they use Heuristic (computer science), heuristic methods to build, search and evaluate Tree (data structure), trees representing sequences of moves from the current position and attempt to execute ...

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 '' 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, 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.

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 ...

Chess Review
''Chess Review'' was an U.S. chess magazine published from January 1933 to October 1969 (Volume 37 Number 10). Until April 1941 it was called ''The Chess Review''. Published in New York, it began on a schedule of at least ten issues a year but later became a monthly. Isaac Kashdan was the editor for the first year, with Al Horowitz and Fred Reinfeld associate editors. After one year, Kashdan left and Horowitz became the editor, a position he retained for the remainder of the magazine's existence. ''Chess Review'' was virtually unchallenged as the premier U.S. chess periodical from its start in 1933 until a rival emerged in 1961 after a major revamp of the official United States Chess Federation magazine, ''Chess Life''. The two magazines remained in competition until November 1969, when Horowitz retired and the magazines were merged to become ''Chess Life & Review''. History The cover of the first issue featured a chess problem composed by Otto Wurzburg (1875–1951), a Grand ...

Martin Kruskal
Martin David Kruskal (; September 28, 1925 – December 26, 2006) was an American mathematician and physicist. He made fundamental contributions in many areas of mathematics and science, ranging from plasma physics to general relativity and from nonlinear analysis to asymptotic analysis. His most celebrated contribution was in the theory of solitons. He was a student at the University of Chicago and at New York University, where he completed his Ph.D. under Richard Courant in 1952. He spent much of his career at Princeton University, as a research scientist at the Plasma Physics Laboratory starting in 1951, and then as a professor of astronomy (1961), founder and chair of the Program in Applied and Computational Mathematics (1968), and professor of mathematics (1979). He retired from Princeton University in 1989 and joined the mathematics department of Rutgers University, holding the David Hilbert Chair of Mathematics.

Chess Handicap
Handicaps (or odds) in chess are handicapping variants which enable a weaker player to have a chance of winning against a stronger one. There are a variety of such handicaps, such as odds (the stronger player surrenders a certain piece or pieces), extra moves (the weaker player has an agreed number of moves at the beginning of the game), extra time on the chess clock, and special conditions (such as requiring the odds-giver to deliver checkmate with a specified piece or pawn). Various permutations of these, such as ''pawn and two moves'', are also possible. Handicaps were quite popular in the 18th and 19th centuries, when chess was often played for money stakes, in order to induce weaker players to play for wagers. Today handicaps are rarely seen in serious competition outside of human–computer chess matches. As chess engines have been routinely superior to even chess masters since the late 20th century, human players need considerable odds to have practical chances in such ma ...

Castling
Castling is a move in chess. It consists of moving the king (chess), king two squares toward a rook (chess), 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 notation (chess), algebraic and descriptive notation, 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

En Passant
In chess, ''en passant'' (, "in passing") describes the capture by a Pawn (chess), pawn of an enemy pawn on the same and an adjacent that has just made an initial two-square advance. This is a special case in the rules of chess. The capturing pawn moves to the square that the enemy pawn passed over, as if the enemy pawn had advanced only one square. The rule ensures that a pawn cannot use its two-square move to safely skip past an enemy pawn. Capturing ''en passant'' is permitted only on the turn immediately after the two-square advance; it cannot be done on a later turn. The capturing move is sometimes Chess notation, notated by appending the abbreviation e.p. Rules The conditions for a pawn to capture an enemy pawn ''en passant'' are as follows: * the enemy pawn Rules of chess#Basic moves, advanced two squares on the previous turn; * the capturing pawn attacks the square that the enemy pawn passed over. If these conditions are met, the capturing pawn can move diagonal ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
