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, ...

Orthodox Defense
The Queen's Gambit Declined (or QGD) is a chess opening in which Black declines a pawn offered by White in the Queen's Gambit: :1. d4 d5 :2. c4 e6 This is known as the ''Orthodox Line'' of the Queen's Gambit Declined. When the "Queen's Gambit Declined" is mentioned, it is usually assumed to be referring to the Orthodox Line; see " Other lines" below. The Orthodox Line can be reached by a number of different , such as 1.d4 Nf6 2.c4 e6 3.Nf3 d5; 1.d4 e6 2.c4 d5; 1.c4 e6 2.Nc3 d5 3.d4; 1.Nf3 d5 2.c4 e6 3.d4; and so on. General concepts Playing 2...e6 releases Black's dark-squared bishop, while obstructing his light-squared bishop. By declining White's temporary pawn sacrifice, Black erects a solid position; the pawns on d5 and e6 give Black a foothold in the . The Queen's Gambit Declined has the reputation of being one of Black's most reliable defenses to 1.d4. In this situation, White will try to exploit the passivity of Black's light-squared bishop, and Black will try to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1848 In Chess
1848 is historically famous for the wave of revolutions, a series of widespread struggles for more liberal governments, which broke out from Brazil to Hungary; although most failed in their immediate aims, they significantly altered the political and philosophical landscape and had major ramifications throughout the rest of the century.

Légal Trap
The Légall Trap or Blackburne Trap (also known as Légall Pseudo-Sacrifice and Légall Mate) is a chess opening , characterized by a queen sacrifice followed by checkmate with minor pieces if Black accepts the sacrifice. The trap is named after the French player Sire de Légall. Joseph Henry Blackburne, a British master and one of the world's top five players in the latter part of the 19th century, set the trap on many occasions. Natural move sequence There is a number of ways the trap can arise; the one below shows a natural move sequence from a simultaneous exhibition in Paris. André Cheron, one of France's leading players, won with the trap as White against Jeanlose: 1. e4 e5 2. Nf3 Nc6 3. Bc4 d6 :The Semi-Italian Opening. 4. Nc3 Bg4 :Black pins the knight in the fight over the center. Strategically this is a sound idea, but there is a tactical flaw with the move. 5. h3 :In this position 5.Nxe5 would be .

Check (chess)
In chess and similar games, check is a condition that occurs when a player's king is under threat of on the opponent's next turn. A king so threatened is said to be in check. A player must get out of check if possible by moving the king to a safe square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot get out of check by any of these options, the game ends in checkmate, and the player loses. Players cannot make any move that puts their own king in check. Many chess variants feature check, such as shogi, xiangqi, and janggi. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or occasionally two) of the player's pieces. Making a move that checks is sometimes called "giving check". Even if a piece is pinned against the player's own king, it may still give check. For example, in the diagrammed position, White has just played Be4+, simultaneous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen (chess)
The queen (♕, ♛) is the most powerful piece in the game of chess. It can move any number of squares vertically, horizontally or , combining the powers of the rook and bishop. Each player starts the game with one queen, placed in the middle of the first next to the king. Because the queen is the strongest piece, a pawn is promoted to a queen in the vast majority of cases. The predecessor to the queen is the '' 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 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 and the black queen starts on a black square—thus the mnemonics "queen gets her color", "queen on er wncolor", or "t ...

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 oppos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge Springs Defense
In chess, the Cambridge Springs Defense (or less commonly, the Pillsbury Variation) is a variation of the Queen's Gambit Declined that begins with the moves: :1. d4 d5 :2. c4 e6 :3. Nc3 Nf6 :4. Bg5 Nbd7 :5. Nf3 c6 :6. e3 Qa5 Black breaks the pin on the h4–d8 diagonal and forms a pin of his own on the c3-knight (exploiting the absence of the White's queen bishop from the ). If Black later plays dxc4, there may be threats against the g5-bishop. Note that 5.cxd5 cannot win a pawn because of the Elephant Trap. The main line continues 7.Nd2 Bb4 with the threat of ...Ne4 and pressure along the a5–e1 diagonal. The ''Encyclopaedia of Chess Openings'' code is D52. Background The first recorded use of the Cambridge Springs was by Emanuel Lasker in 1892. The name derives from a 1904 tournament in Cambridge Springs, Pennsylvania, in which the defense was used several times. Practitioners of the opening have included Efim Bogoljubov, Vasily Smyslov, Garry Kasparov, and M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White And Black In Chess
In chess, the player who moves first is called White and the player who moves second is called Black. Their pieces are the white pieces and the black pieces. The pieces are often not literally white and black, but some other colors, usually a light color and a dark color. The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise the "white squares" or "light squares", and "black squares" or "dark squares"; they are usually of contrasting light and dark color rather than literally white and black. For example, the squares on vinyl boards may be off-white ("buff") and green, while those on wood boards are often light brown and dark brown. white: 1. There are 16 light-colored pieces and 32 squares called white. 2. When capitalized, the word refers to the player of the white pieces. An entry in the ''Glossary of terms in the Laws of Chess'' at the end of the current FIDE laws appears for black, too. In old chess writings, the sides are often called Red ...

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 smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
