Key Square
In chess, particularly in endgames, a key square (also known as a ''critical square'') is a square such that if a player's king can occupy it, he can force some gain such as the promotion of a pawn or the capture of an opponent's pawn. Key squares are useful mostly in endgames involving only kings and pawns. In the king and pawn versus king endgame, the key squares depend on the position of the pawn and are easy to determine. Some more complex positions have easily determined key squares while other positions have harder-to-determine key squares. Some positions have key squares for both White and Black. King and pawn versus king In an endgame with a king and pawn versus a king, the key squares are relative to the position of the pawn. Assume that White has the pawn. If the white king can occupy a key square, he can force the promotion of the pawn but accurate play is required. Whether or not the white king can reach a key square depends on the position of the pieces an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Xol45
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 ...

Mutual 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 ...

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 ...

Triangulation (chess)
Triangulation is a tactic used in chess to put one's opponent in zugzwang (a position when it is a disadvantage to move). Triangulation is also called ''losing a tempo'' or ''losing a move''. Triangulation occurs most commonly in endgames with only kings and pawns when one king can maneuver on three adjacent squares in the shape of a triangle and maintain the basic position while the opposing king only has two such squares. Thus, if one king triangulates by using three moves to return to the original square and the opposing king cannot do the same, he has lost a crucial tempo and reached the same position with the other player to move. Triangulation can occur in other endgames and even in some middlegames. Example Consider this position, with White to move. Here, Black has the opposition and is keeping the white king out. However, if White had the opposition (i.e. it were Black's move in this position), the black king would have to move away from d7 and allow the white ki ...

Chess Endgame
In chess and other similar games, the endgame (or end game or ending) is the stage of the game when few pieces are left on the board. The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs 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 attempting to promote a pawn by advancing it to the eighth . The king, which normally should stay hidden during the game should become active in the endgame, as it can help escort pawns to the promotion square, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. All chess positions with up to seven pieces on the board have been solved, that is, the outcome (win, loss, or draw) of best play by both sides is known, and textbooks and reference works teach th ...

Corresponding Squares
In chess, two squares are corresponding squares (also known as relative squares, sister squares, or coordinate squares) if the occupation of one of these squares by a king requires the enemy king to move to the other square in order to hold the position. Corresponding squares exist in some chess endgames, usually ones that are mostly blocked. Usually, there are several groups of corresponding squares. In some cases, they indicate which square the defending king must move to in order to keep the opposing king away. In other cases, a maneuver by one king puts the other player in a situation where he cannot move to the corresponding square, so the first king is able to penetrate the position. The theory of corresponding squares is more general than opposition and is more useful in cluttered positions. In this article, all members of a pair of corresponding squares are labeled with the same number, i.e. 1, 2, etc. Details Corresponding squares are squares of reciprocal (or mutual) zug ...

Draw (chess)
In chess, there are a number of ways that a game can end in a draw, neither player winning. Draws are codified by various rules of chess including stalemate (when the player to move is not in check but has no legal move), threefold repetition (when the same position occurs three times with the same player to move), and the fifty-move rule (when the last fifty successive moves made by both players contain no or pawn move). Under the standard FIDE rules, a draw also occurs in a dead position (when no sequence of legal moves can lead to checkmate), most commonly when neither player has sufficient to checkmate the opponent. Unless specific tournament rules forbid it, players may agree to a draw at any time. Ethical considerations may make a draw uncustomary in situations where at least one player has a reasonable chance of winning. For example, a draw could be called after a move or two, but this would likely be thought unsporting. In the 19th century, some tournaments, notably ...

George Walker (13 March 1803 – 23 April 1879) was an English chess player and author of ''The Celebrated Analysis of A D Philidor'' (London, 1832), ''The Art of Chess-Play: A New Treatise on the Game of Chess'' (London, 1832), ''A Selection of Games at Chess played by Philidor'' (London, 1835), ''Chess Made Easy'' (London, 1836), and ''Chess Studies'' (London, 1844).

He won a match against Daniel Harrwitz (7-5) at London 1846.
