Alekhine's Gun
Alekhine's gun is a formation in chess named after the former world chess champion Alexander Alekhine. It is a specific kind of battery. This formation was named after a game he played against Aron Nimzowitsch in Sanremo 1930, ending with Alekhine's decisive victory. Concept The idea consists of placing the two rooks stacked one behind another and the queen at the rear. This can lead to substantial material loss for the opponent as it places considerable pressure on the "target" of the gun, especially if it is pinned (in this case it was only four moves before ).

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 ...

Chess Tactics
In chess, a tactic is a sequence of moves that each makes one or more immediate threats ─ that is, a Check (chess), check, a Glossary of chess#material, material threat, a Checkmate, checkmating sequence threat, or the threat of another tactic ─ which culminates in the opponent being unable to respond to all of the threats without conceding an immediate benefit to the opponent. Most often, the immediate benefit takes the form of a material advantage or checkmating attack; however, some tactics are used for defensive purposes and can salvage material that would otherwise be lost, or to induce stalemate in an otherwise lost position. Tactics are usually contrasted with Chess strategy, strategy, whereby the individual moves by themselves don't make indefensible threats, and the cumulative advantage of the moves takes longer to be capitalised on. In rough terms, the dichotomy can be summarised as tactics concerning short-term play and strategy concerning long-term play. Examples of ...

William Winter (chess Player)
William Winter (11 September 1897 – 18 December 1955) was a British chess player. He won the British Open Chess Championship in 1934 and the British Chess Championship in 1935 and 1936. An acolyte of Siegbert Tarrasch, his sound, strategic play enabled him to defeat a number of the world's top players, including David Bronstein, Aron Nimzowitsch and Milan Vidmar. Unfortunately, his health and tactical play were insufficiently strong to enable him to repeat these victories on a consistent basis. Life and career Winter was a widely respected author of chess books and was a nephew of J. M. Barrie, the creator of Peter Pan.Sunnucks, pp. 526–27 Winter was also a Communist. His over-the-board and real-life characters were in stark contrast to each other. Harry Golombek described his play as "classic, scientific and sober; away from the board, he was revolutionary, illogically moved by his emotions (he contrived to be both a fervent communist and a staunch patriot) and, more often ...

Zugzwang
Zugzwang (German for "compulsion to move", ) is a situation found in chess and other turn-based games wherein one player is put at a disadvantage because of their obligation to make a move; a player is said to be "in zugzwang" when any legal move will worsen their position. Although the term is used less precisely in games such as chess, it is used specifically in combinatorial game theory to denote a move that directly changes the outcome of the game from a win to a loss. Putting the opponent in zugzwang is a common way to help the superior side win a game, and in some cases it is necessary in order to make the win possible. The term ''zugzwang'' was used in German chess literature in 1858 or earlier, and the first known use of the term in English was by World Champion Emanuel Lasker in 1905. The concept of zugzwang was known to chess players many centuries before the term was coined, appearing in an endgame study published in 1604 by Alessandro Salvio, one of the first writers ...

Pin (chess)
In chess, a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece. Moving the attacking piece to effect the pin is called ''pinning''; the defending piece restricted by the pin is described as ''pinned''. Only a piece that can move any number of squares along a horizontal, vertical, or diagonal line (i.e. a bishop, rook, or queen) can pin. Any piece can be pinned except the king, which is the most valuable piece. The inverse of a pin is a skewer, in which a more valuable piece under direct attack may move to expose a less valuable piece to an attack. Types Absolute pin An ''absolute pin'' is one where the piece shielded by the pinned piece is the king. In this case it is illegal to move the pinned piece out of the line of attack, as that would place one's king in check (see diagram). A piece pinned in this way can still give check or defend another piece from capture by the opposing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen (chess)

The predecessor to the queen is the ''Ferz (chess), ferz'', a weak piece only able to move or capture one step diagonally, originating from the Persian game of shatranj. The modern queen gained its power and its modern move in Spain in the 15th century during Isabella of Castile, Isabella I's reign, perhaps inspired by her great political power. Placement and movement The white queen starts on d1, while the black queen starts on d8. With the chessboard oriented correctly, the white queen starts on a white square a ...
