Block (chess)
A block is a Outline of chess#Defensive tactics, defensive tactic in chess in response to an attack, consisting of interposing a chess piece, piece between the opponent's attacking piece and the piece being attacked. This type of blocking will only work if the attacking piece is a type that can move linearly an indefinite number of squares such as a queen (chess), queen, rook (chess), rook, or bishop (chess), bishop and there is at least one empty square in the line between the attacking and attacked piece. Blocking is not an option when the attacking piece is directly adjacent to the piece it is attacking, or when the attacking piece is a knight (chess), knight (because knights "jump over other pieces" and cannot be blocked). When an opponent's attack on a piece is blocked, the blocking piece is to some extent Pin (chess), pinned, either relatively or absolutely, until a future move by either side allows it to be unpinned.

Chess Tactic
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. Oft ...

Prophylaxis (chess)
In chess, prophylaxis consists of a move or series of moves done by a player to prevent their opponent from taking some action. Such preventive moves, or ''prophylactic moves'', aim not only to improve one's position but also to restrict the opponent in improving their own. Many standard and widespread opening moves can be considered prophylactic. One common prophylactic idea is the advance of the near a castled king, which can be done to provide luft and/or to prevent a pin; another is to transfer one's king to the b-file after castling queenside so as to protect an unmoved a-pawn, among other purposes. Prophylaxis is a distinctive feature of , often preventing opponents from entering risky, double-edged lines, as well as punishing opponents who play too aggressively. Using prophylaxis is an essential skill at advanced levels of play. Famous practitioners of prophylactic play include Aron Nimzowitsch, Tigran Petrosian, and Anatoly Karpov; even players, such as Mikhail Tal ...

Cross-check (chess)
In chess, a cross-check (or counter-check) is a Chess tactics, tactic in which a check (chess), check is played in response to a check, especially when the original check is blocked by a chess piece, piece that itself either delivers check or reveals a discovered check from another piece. Sometimes the term is extended to cover cases in which the King (chess), king moves out of check and reveals a discovered check from another piece (this is also known as a ''royal check''); it does not generally apply to cases where the original checking piece is captured. The cross-check is an essential tactic in winning some chess endgame, endgames such as those with two queen (chess), queens versus one, or a queen and pawn versus queen endgame, queen and pawn versus a queen. In these cases, the defense usually tries for a perpetual check and sometimes the stronger side can stop it only by a cross-check. Examples A cross-check occurs from time to time in games. It is an essential chess tactic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discovered Attack
In chess, a discovered attack is a direct attack revealed when one piece moves out of the way of another. Discovered attacks can be extremely powerful, as the piece moved can make a threat independently of the piece it reveals. Like many chess tactics, they often succeed because the opponent would be unable to meet two threats at once unless one of the attacked pieces can simultaneously move away from its own attack and capture the other attacking piece. While typically the consequence of a discovered attack is the gain of , they do not have to do this to be effective; the tactic can be used merely to gain a tempo. at MarkLowery.net If the discovered attack is a check, it is ca ...

Initiative (chess)
Initiative in a chess position belongs to the player who can make threats that cannot be ignored, thus putting the opponent in the position of having to spend turns responding to threats rather than creating new threats. A player with the initiative will often seek to maneuver their pieces into more and more advantageous positions as they launch successive attacks. The player who lacks the initiative may seek to regain it through . Discussion Due to moving first, White starts the game with the initiative, but it can be lost in the opening by accepting a gambit. Players can also lose initiative by making unnecessary moves that allow the opponent to gain tempo In musical terminology, tempo (Italian for 'time'; plural 'tempos', or from the Italian plural), measured in beats per minute, is the speed or pace of a given musical composition, composition, and is often also an indication of the composition ..., such as superfluous "preventive" ( prophylactic) moves intended to guar ...

Interference (chess)
In the game of chess, interference occurs when the line between an attacked piece and its defender is interrupted by sacrificially interposing a piece. It is a chess tactic which seldom arises, and is therefore often overlooked. Opportunities for interference are rare because the defended object must be more valuable than the sacrificed piece, and the interposition must itself present a threat. Huczek defines interference as a tactic involving blocking moves that obstruct lines of attack. This definition may be expanded by including blocking moves that disrupt lines of defense. Examples In diagram A, White to play will apparently be obliged to retreat the knight from f5, because the squares to which it could advance are all guarded. The interference move 1.Nd6+, however, interrupts the black rook's defense of the black queen. If Black plays either 1...cxd6 or 1...Bxd6, White will capture Black's queen. Therefore, Black has no better play than 1...Rxd6 2.exd6 Qxe2 3.Rxe2 Bxd6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Unlike all other pieces, each player can have only one king, and the kings are never ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 an unattacked square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot remove the check by any of these options, or if using any of these options would result in the player being in check by another piece, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or, in rare cases, 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 ...
