Opposition (chess)
In chess, opposition (or direct opposition) is a situation in which two kings are two squares apart on the same or . Since kings cannot move adjacent to each other, each king prevents the other's advance, creating a mutual blockade. In this situation, the player not having to move is said to ''have the opposition''. It is a special type of zugzwang and most often occurs in endgames with only kings and pawns. The side with the move may have to move their king away, potentially allowing the opposing king access to important squares. Taking the opposition is a means to an end, normally to force the opponent's king to move to a weaker position, and is not always the best thing to do. There are extensions of direct opposition, such as diagonal opposition and distant opposition, which can be conducive to reaching direct opposition. All three types may be referred to simply as ''opposition'' if the type is unambiguous in context. Direct opposition ''Direct opposition'' is a posit ...

Chess Kll45
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, two bi ...

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 ...

My 60 Memorable Games
''My 60 Memorable Games'' is a chess book by Bobby Fischer, first published in 1969. It is a collection of his games dating from the 1957 New Jersey Open to the 1967 Sousse Interzonal. Unlike many players' anthologies, which are often titled ''My Best Games'' and include only wins or draws, ''My 60 Memorable Games'' includes nine draws and three losses. It has been described as a "classic of objective and painstaking analysis" and is regarded as one of the great pieces of chess literature. The book was originally published in descriptive notation. An algebraic notation version in 1995 caused some controversy in the chess world because of the many other changes made to the text, with Fischer himself denouncing the edition. In 2008 a reissue of Fischer's original text was published, the only changes being the updating to algebraic notation and the correcting of typographical errors, notation mistakes, and the erroneous last few moves of game 17. Writing The book had been planned f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random House
Random House is an American book publisher and the largest general-interest paperback publisher in the world. The company has several independently managed subsidiaries around the world. It is part of Penguin Random House, which is owned by German media conglomerate Bertelsmann. History Random House was founded in 1927 by Bennett Cerf and Donald Klopfer, two years after they acquired the Modern Library imprint from publisher Horace Liveright, which reprints classic works of literature. Cerf is quoted as saying, "We just said we were going to publish a few books on the side at random," which suggested the name Random House. In 1934 they published the first authorized edition of James Joyce's novel ''Ulysses'' in the Anglophone world. ''Ulysses'' transformed Random House into a formidable publisher over the next two decades. In 1936, it absorbed the firm of Smith and Haas—Robert Haas became the third partner until retiring and selling his share back to Cerf and Klopfer in 19 ...

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 ...

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 ...

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 ...

Yuri Averbakh
Yuri Lvovich Averbakh (russian: Ю́рий Льво́вич Аверба́х; 8 February 1922 – 7 May 2022) was a Russian chess grandmaster and author. He was chairman of the USSR Chess Federation from 1973 to 1978. He was the first centenarian FIDE Grandmaster. Despite his eyesight and hearing having worsened, by his 100th birthday he continued to devote time to chess-related activities. Early life Averbakh was born in Kaluga, Russia. His father was German Jewish, and his ancestors were named Auerbach, meaning "meadow brook". His mother was Russian. Both sets of grandparents disapproved of their marriage because his father was likely an atheist and his mother was Eastern Orthodox, as well as the fact that his maternal grandmother died very young, so his mother was expected to look after the family. Averbakh called himself a fatalist. Career Tournament successes His first major success was the first place in the Moscow Championship of 1949, ahead of players including Andor ...
