Losing Chess
Losing chess is one of the most popular chess variants. The objective of each player is to lose all of their pieces or be stalemated, that is, a misère version. In some variations, a player may also win by checkmating or by being checkmated. Losing chess was weakly solved in 2016 by Mark Watkins as a win for White, beginning with 1.e3. Rules (main variant) The rules are the same as those for standard chess, except for the following special rules: * Capturing is compulsory. ** When more than one capture is available, the capturing player may choose. * The king has no , being effectively replaced by a mann, and accordingly: ** it may be captured like any other piece; ** there is no check or checkmate; *** therefore the king may expose itself to capture; ** there is no castling; ** a pawn may also be promoted to a king. * Stalemate is a win for the stalemated player (the player with no legal moves). This includes having no remaining pieces on the board. Draws by re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

David Pritchard (chess Player)

Features; p. 66. 17 January 2006. was a British chess player, chess writer and indoor games consultant. He gained pre-eminence as an indoor games and mind sports consultant, a role that he in effect created. A natural games player, it was to him that inventors or publishers would turn to organise a championship of a new game, write about it or generally promote it. Though nearly a million copies of his chess books have been sold, Pritchard is best known for authoring ''The Encyclopedia of Chess Variants'', in which he describes more than 1400 different variants.

Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages.

Bare King
In chess and chess variants, a bare king (or lone king) is a king whose player has no other remaining pieces (i.e. all the player's other pieces have been ). Effect on the game Historical In some old versions of chess, such as "baring chess" and shatranj, leaving the opponent with a bare king was one way of winning the game (see ). The relative weakness of the pieces in shatranj may have made this form of a win desirable. A possible exception to the bare king rule was if the king immediately after being bared was able to recapture, leaving the opponent with a bare king as well. This situation, called a "Medinese victory" (because in Medina, it was still a win for the player first baring the opposing king), was often considered a draw. Contemporary Under modern rules, a player with a bare king does not automatically lose and may continue playing. A bare king can never give check, however, and can therefore never deliver a checkmate or win the game. A bare king can in some situa ...

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 ...

Endgame (chess)
The endgame (or ending) is the final stage of a chess game which occurs after the middlegame. It begins when few pieces are left on the board. The line between the middlegame and the endgame is often not clear, and may occur gradually or with a quick exchange of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important as endgames often revolve around attempts to promote a pawn by advancing it to the eighth . The king, which normally is kept safe during the game, becomes active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases, so the outcome (win, loss, or draw) of best play by both ...

Solved Game
A solved game is a game whose outcome (win, lose or tie (draw), 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 or computer assistance. Overview A two-player game can be solved on several levels: Ultra-weak solution : 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 details of the perfect play. Weak solution : Provide one algorithm for each of the two players, such that the player using it can achieve at least the optimal outcome, regardless of the opponent's moves, from the start of the game, using reasonable computational resources. Strong solution : Provide an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suicide Chess 1
Suicide is the act of intentionally causing one's own death. Risk factors for suicide include mental disorders, physical disorders, and substance abuse. Some suicides are impulsive acts driven by stress (such as from financial or academic difficulties), relationship problems (such as breakups or divorces), or harassment and bullying. Those who have previously attempted suicide are at a higher risk for future attempts. Effective suicide prevention efforts include limiting access to methods of suicide such as firearms, drugs, and poisons; treating mental disorders and substance abuse; careful media reporting about suicide; improving economic conditions; and dialectical behaviour therapy (DBT). Although crisis hotlines, like 988 in North America and 13 11 14 in Australia, are common resources, their effectiveness has not been well studied. Suicide is the 10th leading cause of death worldwide, accounting for approximately 1.5% of total deaths. In a given year, this is ...
