Extinction Chess
Extinction chess is a chess variant invented by R. Wayne Schmittberger, editor of '' Games'' magazine, in 1985. Instead of checkmate as the winning condition, the object of the game is the elimination of all of a particular type of piece of the opponent. In other words, the objective is any of the following: * capture all the opponent's kings; * capture all the opponent's queens; * capture all the opponent's rooks; * capture all the opponent's bishops; * capture all the opponent's knights; * eliminate all of the opponent's pawns, by capturing or by promotion. A promoted pawn is considered no longer a pawn. By the same token, if a player already has a queen, and promotes a pawn to another queen, then both queens would need to be captured to make them extinct. The king is not a special piece in this game, and it is legal to promote a pawn to a king. It is also legal to castle when in check, or to castle through check. The other rules of castling are the same: the king and the ro ...

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 ...

Games (magazine)
''GAMES World of Puzzles'' is a puzzle magazine formed from the merger of Games and World of Puzzles in October 2014. The entire magazine interior is now newsprint (as opposed to the part-glossy/part-newsprint format of the original ''Games'') and the puzzles and articles that originally sandwiched the "Pencilwise" section are now themselves sandwiched ''by'' the main puzzle pages, replacing the "feature puzzle" section. (They are still full-color, unlike the two-color "Pencilwise" sections.) Like the original ''World of Puzzles'' (which is now discontinued), the answer key is now at the rear of the magazine. The new combined title remained on the same 9-issue-per-year publication schedule as the original ''Games''. Games ''Games'' magazine (ISSN 0199-9788) was a magazine devoted to games and puzzles, and it was published by Games Publications, a division of Kappa Publishing Group. History Games was originally published by ''Playboy'' (debuting with the September/October 1977 i ...

Checkmate
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated. In formal games, it is usually considered good etiquette to resign an inevitably lost game before being checkmated. If a player is not in check but has no legal move, then it is '' stalemate'', and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol "#", for example: 34.Qg3#. Examples A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in Fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), or after many moves with as few as t ...

Chess Piece
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 and Black in chess, white or black, and it can be one of six types: King (chess), king, Queen (chess), queen, Rook (chess), rook, Bishop (chess), bishop, Knight (chess), knight, or Pawn (chess), pawn. Chess sets generally come with sixteen pieces of each color. Additional pieces, usually an extra queen per color, may be provided for use in Promotion (chess), promotion. Number of pieces Each player begins with sixteen pieces (but see the #Usage of the term piece, subsection below for other usage of the term ''piece''). The pieces that belong to each player are distinguished by color: the lighter colored pieces are referred to as "white" and the player that owns them as "White", whereas the darker colored pieces are referred to as "black" and the player that owns them as "Black". In a standard game, each of the two players begins with the following sixteen ...

Promotion (chess)
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last . The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same . The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn. Promotion to a queen is known as queening; promotion to any other piece is known as underpromotion. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame. Rules When a pawn is promoted, it is removed from the board, and the new piece is placed on the square of promotion. A piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more queens, or three or more rooks, bishops, or kni ...
