Open File
An open file in chess is a with no pawns of either color on it. In the diagram, the e-file is an open file. An open file can provide a line of attack for a rook or queen. Having rooks or queens on open files or half-open files is considered advantageous, as it allows a player to attack more easily, since a rook or queen can move down the file to penetrate the opponent's position. Strategic advantage A common strategic objective for a rook or queen on an open file is to reach its seventh or eighth (the opponent's second or first rank). Controlling the seventh rank is generally worth at least a pawn, as it threatens all the opponent's yet-unmoved pawns to some degree. Controlling the eighth rank is likely to force the opposing king into a more exposed position and puts pressure on any remaining pieces, or if the rank is already clear, allows unobstructed movement behind the enemy forces. Aron Nimzowitsch first recognized the power of a on an open file, writing in his famous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 rook (; ♖, ♜) is a piece in the game of chess. It may move any number of squares horizontally or vertically without jumping, and it may an enemy piece on its path; additionally, it may participate in castling. Each player starts the game with two rooks, one in each corner on their own side of the board. Formerly, the rook (from Persian رخ ''rokh''/''rukh'', meaning "chariot") was alternatively called the tower, marquess, rector, and comes (count or earl). The term "castle" is considered to be informal, incorrect, or old-fashioned. Placement and movement The white rooks start on squares a1 and h1, while the black rooks start on a8 and h8. The rook moves horizontally or vertically, through any number of unoccupied squares (see diagram). The rook cannot jump over pieces. The rook may capture an enemy piece by moving to the square on which the enemy piece stands, removing it from play.

Queen (chess)
The queen (♕, ♛) is the most powerful chess piece, piece in the game of chess.

Each player starts the game with one queen, placed in the middle of the first next to the King (chess), king. Because the queen is the strongest piece, a pawn (chess), pawn is promotion (chess), promoted to a queen in the vast majority of cases. The predecessor to the queen is the ''Ferz (chess), 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 of Castile, 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 a ...

Half-open File
In chess, a half-open file (or semi-open file) is a with pawns of only one color. The half-open file can provide a line of attack for a player's rook or queen. A half-open file is generally exploited by the player with no pawns on it. Many openings, such as the Sicilian Defense, aim to complicate the position. In the main line Sicilian, 1.e4 c5 2.Nf3 d6 (or 2...e6, or 2...Nc6) 3.d4 cxd4 4.Nxd4, White obtains a half-open d-file, but Black can pressure White along the half-open c-file. In positions where White has no pawns on a file but Black has one pawn or more on that file, the position is considered to be half-opened for white. During instances where Black has zero pawns on a file but White has one or more pawns on that file, the position is considered to be half-opened for black. In such instances where pawns capture or advance, in a way that it opens or half-opens a file or files, this instance is called a pawn break. The demolition of the pawn structure is a common th ...

The Elements In "The Elements" (german: Die Elemente), Nimzowitsch writes about the basics of his "system". He regards the following as the elements of chess strategy: # The center # Play on the open files # Play on the seventh and eighth ranks # The passed pawns # The pin # Discovered checks # Exchanging # The pawn-chain Positional Play The next part, "Positional Play" (german: Das Positionsspiel), is based largely on the elements taught in the first part.

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 ...
