Battery (chess)
A battery in chess is a formation that consists of two or more pieces on the same rank, file, or diagonal. It is a tactic involved in planning a series of captures to remove the protection of the opponent's king, or to simply gain in the exchanges. Other chess authors limit battery to "an arrangement of two pieces ''in line with the enemy king'' on a rank, file, or diagonal so that if the middle piece moves a discovered check will be delivered." However, in Chessgames.com blogs and game annotations of other chess websites, the term is also used in cases where moving the middle piece will uncover a threat other than a check along the opened line. Discussion and examples It is particularly effective to form a battery using rooks because they may be combined to occupy the same rank or file. In theory, bishops may also form a battery in a case of underpromotion of a pawn to a bishop occupying the same diagonal as the other bishop. In actual games, however, the queen and rooks are ...

Rook (chess)
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; it may participate in castling. Each player starts the game with two rooks, one in each corner on their side of the board. Formerly, the rook (from ) was alternatively called the ''tower'', ''marquess'', ''rector'', and ''comes'' (''count'' or ''earl''). The term "castle" is considered to be informal or old-fashioned. Placement and movement The white rooks start on the 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. 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. The rook also participates with the king in a special move called castling, wherein it is transferred to the square crossed by the king after th ...

Bishop (chess)
The bishop (♗, ♝) is a Chess piece, piece in the game of chess. It moves and captures along without jumping over interfering pieces. Each player begins the game with two bishops. The starting squares are c1 and f1 for White's bishops, and c8 and f8 for Black's bishops. Placement and movement The is placed on f1 for White and f8 for Black; the is placed on c1 for White and c8 for Black. The bishop has no restrictions in distance for each move but is limited to diagonal movement. It cannot jump over other pieces. A bishop captures by occupying the square on which an enemy piece stands. As a consequence of its diagonal movement, each bishop always remains on one square color. Due to this, it is common to refer to a bishop as a ''light-squared'' or ''dark-squared'' bishop. Comparison – other pieces Versus rook A rook (chess), rook is generally worth about two Pawn (chess), pawns more than a bishop. The bishop has access to only half of the squares on the board, w ...

Sicilian Defence
The Sicilian Defence is a chess opening that begins with the following moves: :1. e4 c5 The Sicilian is the most popular and best-scoring response to White's first move 1.e4. The 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 grandmasters, and 25% of the games in the Chess Informant database, begin with the Sicilian. 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 often obtains an early initiative, so Black has to take care not to fall victim to a quick attack." Gra ...

Chess Tactics
In chess, a tactic is a sequence of moves that each makes one or more immediate threats – a check, a threat, a checkmating sequence threat, or the threat of another tactic or otherwise forcing moves – that culminates in the opponent's being unable to respond to all of the threats without making some kind of concession. Most often, the immediate benefit takes the form of a material advantage or ; however, some tactics are used for defensive purposes and can salvage material that would otherwise be lost, or to induce stalemate in an otherwise lost position. Tactics are usually contrasted with strategy, whereby the individual moves by themselves do not make indefensible threats, and the cumulative advantage of them takes longer to capitalise. The dichotomy can be summarised as tactics concerning short-term play and strategy concerning long-term play. Examples of strategic advantages are in, compromised pawn structure in, and sustained pressure on, the opponent's position. Of ...

Combination (chess)
In chess, a combination is a sequence of moves, often initiated by a sacrifice, which leaves the opponent few options and results in tangible gain. At most points in a chess game, each player has several reasonable options from which to choose, which makes it difficult to plan ahead except in strategic terms. Combinations, in contrast to the norm, are sufficiently forcing that one can calculate exactly how advantage will be achieved against any defense. Indeed, it is usually necessary to see several moves ahead in exact detail before launching a combination, or else the initial sacrifice should not be undertaken. Definition In 1952/53, the editors of '' Shakhmaty v SSSR'' decided on this definition: ''A combination is a forced sequence of moves which uses tactical means and exploits specific peculiarities of the position to achieve a certain goal.'' Irving Chernev wrote:What is a combination? A combination is a blend of ideas – pins, forks, discovered checks, double attack ...

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; if a pawn is promoted to a piece other than a queen, it is an underpromotion. 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 queen acquired its modern move in Spain in the 15th century. 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 "the dress uee ...

Underpromotion
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its . 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 when moving to the last rank; 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 the pawn moved to. Any piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more quee ...

Blogs
A blog (a Clipping (morphology), truncation of "weblog") is an informational website consisting of discrete, often informal diary-style text entries also known as posts.

King (chess)
The king (♔, ♚) is the most important chess piece, piece in the game of chess. It may move to any adjoining square; it may also perform, in tandem with the Rook (chess), rook, a special move called ''castling''. If a player's king is threatened with capture, it is said to be ''in Check (chess), check'', and the player must remove or evade the threat of immediately, such as by moving it away from the attacked square. If this cannot be done, the king is said to be in checkmate, resulting in a loss for that player. A player cannot make any move that places their own king in check. Despite this, the king can become a strong offensive piece in the Chess endgame, endgame or, rarely, the Chess middlegame, middlegame. In Algebraic notation (chess), algebraic notation, the king is abbreviated by the letter ''K'' among English speakers. The white king starts the game on e1; the black king starts on e8.
