Cross-check
In chess, a cross-check is a tactic in which a check is played in response to a check, especially when the original check is blocked by a piece that itself either delivers check or reveals a discovered check from another piece. Sometimes the term is extended to cover cases in which the king moves out of check and reveals a discovered check from another piece (this is also known as a ''royal check''); it does not generally apply to cases where the original checking piece is captured. The cross-check is an essential tactic in winning some endgames such as those with two queens versus one, or a queen and pawn versus a queen. In these cases, the defense usually tries for a perpetual check and sometimes the stronger side can stop it only by a cross-check. Examples A cross-check occurs from time to time in games. It is an essential tactic in winning endgames such as two queens versus one queen, or queen and pawn versus queen, where it is used to stop a series of checks from the o ...

Check (chess)
In chess and similar games, check is a condition that occurs when a player's king is under threat of on the opponent's next turn. A king so threatened is said to be in check. A player must get out of check if possible by moving the king to a safe square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot get out of check by any of these options, the game ends in checkmate, and the player loses. Players cannot make any move that puts their own king in check. Many chess variants feature check, such as shogi, xiangqi, and janggi. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or occasionally two) of the player's pieces. Making a move that checks is sometimes called "giving check". Even if a piece is pinned against the player's own king, it may still give check. For example, in the diagrammed position, White has just played Be4+, simultaneo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pawnless Chess Endgame
A pawnless chess endgame is a chess endgame in which only a few chess piece, pieces remain, and no pawn (chess), pawns. The basic checkmates are types of pawnless endgames. Endgames without pawns do not occur very often in practice except for the basic checkmates of king (chess), king and queen (chess), queen versus king, king and rook (chess), rook versus king, and queen versus rook. Other cases that occur occasionally are (1) a rook and versus a rook and (2) a rook versus a minor piece, especially if the minor piece is a bishop (chess), bishop. The study of some pawnless endgames goes back centuries by players such as François-André Danican Philidor (1726–1795) and Domenico Lorenzo Ponziani (1719–1796). On the other hand, many of the details and recent results are due to the construction of endgame tablebases. Grandmaster (chess), Grandmaster John Nunn wrote a book (''Secrets of Pawnless Endings'') summarizing the research of endgame tablebases for several types of pawnless ...

Queen And Pawn Versus Queen Endgame
The queen and pawn versus queen endgame is a chess endgame in which both sides have a queen and one side has a pawn, which one tries to promote. It is very complicated and difficult to play. Cross-checks are often used as a device to win the game by forcing the exchange of queens. It is almost always a draw if the defending king is in front of the pawn. Karsten Müller and Frank Lamprecht say that this endgame occurs quite frequently but Mark Dvoretsky says that it occurs quite seldom. This is the second most common "piece and pawn versus piece" endgame, next to the rook and pawn versus rook endgame. History Before about 1940 all that was known about this endgame was based on some superficial analysis of a few positions from the time of Philidor (1726–95). Analysts gradually started to analyze the endgame. The endgame occurred in a 1944 game between Botvinnik and Ravinsky (below) and much analysis followed. Paul Keres published a large amount of analysis in 1947–49. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 k ...

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, ...

The Observer
''The Observer'' is a British newspaper published on Sundays. It is a sister paper to ''The Guardian'' and '' The Guardian Weekly'', whose parent company Guardian Media Group Limited acquired it in 1993. First published in 1791, it is the world's oldest Sunday newspaper. History Origins The first issue, published on 4 December 1791 by W.S. Bourne, was the world's first Sunday newspaper. Believing that the paper would be a means of wealth, Bourne instead soon found himself facing debts of nearly £1,600. Though early editions purported editorial independence, Bourne attempted to cut his losses and sell the title to the government. When this failed, Bourne's brother (a wealthy businessman) made an offer to the government, which also refused to buy the paper but agreed to subsidise it in return for influence over its editorial content. As a result, the paper soon took a strong line against radicals such as Thomas Paine, Francis Burdett and Joseph Priestley. 19th century In ...

Flight Square
In chess, a flight square or escape square is a safe square to which a piece, especially a king, can move if it is threatened. Providing one's piece with flight squares can prevent the opponent from winning material or delivering checkmate. For example, in the Morphy Defence, the white c-pawn may be advanced to provide the light-squared white bishop with a flight square. Conversely, it is possible to take away an enemy piece's flight squares, known as domination. Luft In chess, (the German word for "air", sometimes also "space" or "breath") designates the space or square left by a pawn move into which a king (usually a castled one) may then retreat, especially such a space made intentionally to avoid back-rank checkmate. A move leaving such a space is often said to "give the king some luft". The term "luft", "lufting", or "lufted" may also be used (as an English participle) to refer to the movement of the relevant pawn creating luft. (At the 45:26 mark, GM Ben Finegold of ...
