Hedgehog (chess)
The Hedgehog is a pawn formation in chess adopted usually by Black that can arise from several openings. Black exchanges the pawn on c5 for White's pawn on d4, and then places pawns on the squares a6, b6, d6, and e6. These pawns form a row of "spines" behind which Black their forces. Typically, the bishops are placed on b7 and e7, knights on d7 and f6, queen on c7, and rooks on c8 and e8 (or c8 and d8). Although Black's position is cramped, it has great latent energy, which may be released if Black is able to play ...b5 or ...d5 at some point. These pawn breaks are particularly effective because White usually places pawns on c4 and e4 (the Maróczy Bind). Black manoeuvring Once the basic Hedgehog structure is in place, and depending on how White responds, Black has various ways of reorganizing their pieces. The knight on d7 often hops to c5, where it attacks a white pawn on e4; or to e5, where it attacks a pawn on c4. The knight on f6 can go to e8 (when Black placed their roo ...

Pawn (chess)
The pawn (♙, ♟) is the most numerous and weakest piece in the game of chess. It may move one vacant square directly forward, it may move two vacant squares directly forward on its first move, and it may capture one square diagonally forward. Each player begins a game with eight pawns, one on each square of their second . The white pawns start on a2 through h2; the black pawns start on a7 through h7. Individual pawns are referred to by the on which they stand. For example, one speaks of "White's f-pawn" or "Black's b-pawn". Alternatively, they can be referred to by the piece which stood on that file at the beginning of the game, e.g. "White's king bishop's pawn" or "Black's queen knight's pawn". It is also common to refer to a rook's pawn, meaning any pawn on the a- or h-files, a knight's pawn (on the b- or g-files), a bishop's pawn (on the c- or f-files), a queen's pawn (on the d-file), a king's pawn (on the e-file), and a central pawn (on the d- or e-files). The pawn histori ...

Modern Chess Openings
''Modern Chess Openings'' (usually called ) is a reference book on chess openings, first published in 1911 by the British players Richard Clewin Griffith (1872–1955) and John Herbert White (1880–1920). The fifteenth edition was published in 2008. Harry Golombek called it "the first scientific study of the openings in the twentieth century".Harry Golombek (editor-in-chief), ''Golombek's Encyclopedia of Chess'', Crown Publishers, 1977, p. 202. . History Although Bilguer's ''Handbuch des Schachspiels'' was more authoritative at the time ''MCO'' was first published, it was last published between 1912 and 1916, and was becoming outdated by the 1930s. ''MCO'' was popular with English-speaking players and has continued to be updated throughout the 20th century and into the 21st, with fifteen editions from 1911 through 2008. Early editions were small enough to fit in a pocket (the first edition was 190 pages), but later editions grew and the fifteenth and most recent version is 768 ...

Hippopotamus Defence
The Hippopotamus Defence refers to various irregular chess openings in which Black moves a number of pawns to the sixth , often developing pieces to the seventh rank, and does not move any pawns to the fifth rank in the opening. As an , it can also be utilized (albeit much less frequently) by White. Evaluation Chess master and author Fred Reinfeld once stated of it that "any expert player would dismiss Black's position as lost." Grandmaster Reuben Fine, one of the world's strongest players in the 1930s and 1940s, instructing his readers how to deal with such "Irregular Openings", wrote that "once a plus in development or center is set up, a well-conducted attack will decide." Reinfeld, who died in 1964, might have been surprised to see Black employing the same system of development successfully in the 1966 world championship match. There, Boris Spassky employed the same set-up, dubbed the "Hippopotamus" by commentators, in the 12th and 16th match games against World Champion T ...

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 ...

Sicilian Defence
The Sicilian Defence is a chess opening that begins with the following moves: :1. b:Chess Opening Theory/1. e4, e4 b:Chess Opening Theory/1. e4/1...c5, c5 The Sicilian is the most popular and best-scoring response to White's first move 1.e4. Opening 1.d4 is a statistically more successful opening for White because of the high success rate of the Sicilian defence against 1.e4. ''New In Chess'' stated in its 2000 Yearbook that, of the games in its database, White scored 56.1% in 296,200 games beginning 1.d4, but 54.1% in 349,855 games beginning 1.e4, mainly because the Sicilian held White to a 52.3% score in 145,996 games. 17% of all games between Grandmaster (chess), grandmasters, and 25% of the games in the Chess Informant database, begin with the Sicilian. Grandmaster (chess), Grandmaster John Nunn attributes the Sicilian Defence's popularity to its "combative nature": "in many lines Black is playing not just for equality, but for the advantage. The drawback is that White o ...

Queen's Indian Defence
The Queen's Indian Defense (QID) is a chess opening defined by the moves: :1. d4 Nf6 :2. c4 e6 :3. Nf3 b6 The opening is a solid defense to the Queen's Pawn Game. 3...b6 increases Black's control over the central light squares e4 and d5 by preparing to fianchetto the , with the opening deriving its name from this maneuver. As in the other Indian defenses, Black attempts to control the with pieces in hypermodern style, instead of occupying it with pawns in classical style. By playing 3.Nf3, White sidesteps the Nimzo-Indian Defense that arises after 3.Nc3 Bb4. The Queen's Indian is regarded as the sister opening of the Nimzo-Indian, since both openings aim to impede White's efforts to gain full control of the center by playing e2–e4. Together, they are a well-respected response to 1.d4. Main line: 4.g3 4. g3 (''ECO'' E15–E19) has long been White's most popular line against the Queen's Indian. It contests the by preparing to fianchetto the light-squared bishop. Th ...

English Opening
The English Opening is a chess opening that begins with the move: :1. c4 A flank opening, it is the fourth most popular and, according to various databases, one of the four most successful of White's twenty possible first moves. White begins the fight for the by staking a claim to the d5-square from the wing, in hypermodern style. Although many lines of the English have a distinct character, the opening is often used as a transpositional device in much the same way as 1.Nf3 – to avoid such highly regarded responses to 1.d4 as the Nimzo-Indian and Grünfeld Defences — and is considered reliable and flexible. The English derives its name from the leading 19th century English master Howard Staunton, who played it during his 1843 match with Saint-Amant and at London 1851, the first international tournament. It did not inspire Staunton's contemporaries and caught on only in the twentieth century. It is now recognised as a opening that may be used to reach both classical an ...

Pawn Structure
In a game of chess, the pawn structure (sometimes known as the pawn skeleton) is the configuration of pawns on the chessboard. Because pawns are the least mobile of the chess pieces, the pawn structure is relatively static and thus plays a large role in determining the strategic character of the position. General observations Weaknesses in the pawn structure, such as isolated, doubled, or backward pawns and , once created, are usually permanent. Care must therefore be taken to avoid them (but there are exceptions—for instance see ''Boleslavsky hole'' below). In the absence of these structural weaknesses, it is not possible to assess a pawn formation as good or bad—much depends on the position of the pieces. The pawn formation does determine the overall strategies of the players to a large extent, however, even if arising from unrelated openings. Pawn formations symmetrical about a vertical line (such as the ''e5 Chain'' and the ''d5 Chain'') may appear similar, but they te ...

Chess Strategy
Chess strategy is the aspect of chess play concerned with evaluation of chess positions and setting of goals and long-term plans for future play. While evaluating a position strategically, a player must take into account such factors as the relative value of the pieces on the board, pawn structure, king safety, position of pieces, and control of key squares and groups of squares (e.g. diagonals, open files, and individual squares). Chess strategy is distinguished from chess tactics, which is the aspect of play concerned with the move-by-move setting up of threats and defenses. Some authors distinguish static strategic imbalances (e.g. having more valuable pieces or better pawn structure), which tend to persist for many moves, from dynamic imbalances (such as one player having an advantage in piece ), which are temporary. This distinction affects the immediacy with which a sought-after plan should take effect. Until players reach the skill level of "master", chess tactics tend to u ...

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 ...
