Compensation (chess)
In chess, compensation is the typically short-term positional advantages a player gains in exchange for typically disadvantage. Short-term advantages involve initiative and . Forms Compensation can include: *Better pawn structure. *The "two bishops", which refers to having bishops of both colors while your opponent does not. Almost all modern players consider having both bishops as an advantage, although historically there has been great debate as to how much of an advantage they constitute. The two bishops are most likely to show their power in the endgame. *Better piece and/or better (common in gambits). *Having the enemy king exposed to future attack, either due to a loss of pawn cover or being trapped in the center of the board, is often excellent compensation. *Passed pawns are often decisive in the endgame. Connected and/or protected passed pawns are even more deadly. *Control over key squares, , , or . Examples Polugaevsky versus Evans A rook on the seventh rank (th ...

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 ...

Basic Chess Endings
''Basic Chess Endings'' (abbreviated BCE) is a book on chess endgames which was written by Grandmaster Reuben Fine and originally published on October 27, 1941. It is considered the first systematic book in English on the endgame phase of the game of chess. It is the best-known endgame book in English and is a classic piece of chess endgame literature. The book is dedicated to World Champion Emanuel Lasker, who died in 1941 (the year the book was published). It was revised in 2003 by Pal Benko. Cecil Purdy said "... ''Basic Chess Endings'' is a monumental work, one of the most complete and authoritative on endgames in any language" . History ''Basic Chess Endings'' was written by Reuben Fine in only four months and was published in 1941 by McKay (a division of Random House) in hardback. The book used the now obsolete descriptive chess notation and used the old system of using the abbreviation "Kt" to stand for knight instead of the more modern "N". In a 1984 interview, Fine ...

Chess Piece Relative Value
In chess, a relative value (or point value) is a standard value conventionally assigned to each piece. Piece valuations have no role in the rules of chess but are useful as an aid to assessing a position. Valuation systems almost always assign a value of 1 point to the pawn, typically as its average value in the starting position. The best known system assigns 1 point to a pawn, 3 points to a knight or bishop, 5 points to a rook and 9 points to a queen. Valuation systems provide only a rough idea of the state of play. The actual value of a piece depends on the game situation and can differ considerably from the standard valuation. A well posted bishop may be more valuable than a passive rook, while a badly placed piece may be completely trapped and thus almost worthless. Chess engines conventionally output their assessment of a position in terms of 'centipawns' (cp), where 100 cp = 1 pawn. In addition to the balance, this assessment incorporates strategic features of the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outpost (chess)
An outpost is a square on the fourth, fifth, sixth, or seventh which is protected by a pawn and which cannot be attacked by an opponent's pawn. Such a square is a hole for the opponent . In the figure to the right, c4 is an outpost, occupied by White's knight. It cannot be attacked by Black's pawns – there is no pawn on the d- and Black's pawn on the b-file is too far advanced. Outposts are a favourable position from which one can launch an attack, particularly using a knight. An outpost is even more effective where it is difficult to trade off with an equal valued piece, e.g., if the opponent only has a bishop of the opposite color to the outpost square's color. Knights are most efficient when they are close to the enemy's stronghold. This is because of their short reach, something not true of bishops, rooks and queens Queens is a borough of New York City, coextensive with Queens County, in the U.S. state of New York.

Knight (chess)
The knight (♘, ♞) is a piece in the game of chess, represented by a horse's head and neck. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-, each located between a rook and a bishop. Movement Compared to other chess pieces, the knight's movement is unique: it moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically (with both forming the shape of a capital L). When moving, the knight can jump over pieces to reach its destination. Knights capture in the same way, replacing the enemy piece on the square and removing it from the board. A knight can have up to eight available moves at once. Knights and pawns are the only pieces that can be moved in the chess starting position. Value Knights and bishops, also known as , have a value of about three pawns. Bishops utili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Exchange (chess)
In chess, the exchange is a situation in which one player exchanges a (i.e. a bishop or knight) for a rook. The side which wins the rook is said to have ''won the exchange'', while the other player has ''lost the exchange'', since the rook is usually more valuable. Alternatively, the side having a rook for a minor piece is said to be ''up the exchange'', and the other player is ''down the exchange''. The opposing captures often happen on consecutive moves, although this is not strictly necessary. It is generally detrimental to lose the exchange, although occasionally one may find reason to purposely do so; the result is an ''exchange sacrifice'' (see below). The ''minor exchange'' is an uncommon term for the exchange of a bishop and knight. "The exchange" differs from the more general "exchange" or "an exchange", which refers to the loss and subsequent gain of arbitrary pieces, for example to "exchange queens" would mean that each side's queen is .

Sacrifice (chess)
In chess, a sacrifice is a move that gives up a piece with the objective of gaining tactical or positional compensation in other forms. A sacrifice could also be a deliberate exchange of a chess piece of higher value for an opponent's piece of lower value. Any chess piece except the king may be sacrificed. Because players usually try to hold on to their own pieces, offering a sacrifice can come as an unpleasant surprise to one's opponent, putting them off balance and causing them to waste precious time trying to calculate whether the sacrifice is sound or not, and whether to accept it. Sacrificing one's queen (the most valuable piece), or a string of pieces, adds to the surprise, and such games can be awarded . Types of sacrifice Real versus sham Rudolf Spielmann proposed a division between sham and real sacrifices: * In a ''real sacrifice'', the sacrificing player will often have to play on with less than their opponent for quite some time. * In a ''sham sacrifice'', t ...

Chess Opening
A chess opening or simply an opening is the initial stage of a chess game. It usually consists of established theory; the other phases are the middlegame and the endgame. Many opening sequences have standard names such as the "Sicilian Defense". ''The Oxford Companion to Chess'' lists 1,327 named openings and variants, and there are many others with varying degrees of common usage. Opening moves that are considered standard are referred to as "book moves", or simply "book". When a game begins to deviate from known opening theory, the players are said to be "out of book". In some openings, "book" lines have been worked out for over 30 moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Gambit
The King's Gambit is a chess opening that begins with the moves: :1. e4 e5 :2. f4 White offers a pawn to divert the black e-pawn. If Black accepts the gambit, White has two main plans. The first is to play d4 and Bxf4, regaining the gambit pawn with domination. The alternative plan is to play Nf3 and Bc4 followed by 0-0, when the semi-open f-file created after a pawn push to g3 allows White to attack the weakest point in Black's position, the pawn on f7. Theory has shown that, in order to maintain the gambit pawn, Black may well be forced to weaken the with moves such as ...g5 or odd piece placement (e.g. ). A downside to the King's Gambit is that it weakens White's king's position, exposing it to the latent threat of ...Qh4+ (or ). With a black pawn on f4, it is not usually viable for White to respond to the check with g2-g3, but if the king moves then it also loses the right to castle. The King's Gambit is one of the oldest documented openings, appearing in one of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bobby Fischer
Robert James Fischer (March 9, 1943January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion. A chess prodigy, he won his first of a record eight US Championships at the age of 14. In 1964, he won with an 11–0 score, the only perfect score in the history of the tournament. Qualifying for the 1972 World Championship, Fischer swept matches with Mark Taimanov and Bent Larsen by 6–0 scores. After another qualifying match against Tigran Petrosian, Fischer won the title match against Boris Spassky of the USSR, in Reykjavík, Iceland. Publicized as a Cold War confrontation between the US and USSR, the match attracted more worldwide interest than any chess championship before or since. In 1975, Fischer refused to defend his title when an agreement could not be reached with FIDE, chess's international governing body, over the match conditions. Consequently, the Soviet challenger Anatoly Karpov was named World Champion by default. Fischer subseq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boris Spassky
Boris Vasilievich Spassky ( rus, Бори́с Васи́льевич Спа́сский, Borís Vasíl'yevich Spásskiy; born January 30, 1937) is a Russian chess grandmaster who was the tenth World Chess Champion, holding the title from 1969 to 1972.
