Three-check Chess
Three-check chess, also simply known as three-check, is a chess variant where a player can win by placing their opponent in check three times. Apart from this, standard rules of chess apply, including starting position and other ending conditions, such as stalemate and checkmate. A move is considered to give one check if the king is threatened, regardless if multiple pieces are checking the king. Three-check can be played over the board, but it is also popular on internet chess servers such as Chess.com and Lichess. History It is unknown specifically where three-check chess originated, but David Pritchard, author of ''The Encyclopedia of Chess Variants'', suspected Soviet origin, and noted that Anatoly Karpov was an "invincible" player of three-check chess in his youth. On Lichess, the three-check world championship is hosted yearly. Other strong players who have played three-check include grandmasters Maxime Vachier-Lagrave and Sergei Zhigalko.

Chess Variant
A chess variant is a game related to, derived from, or inspired by chess. Such variants can differ from chess in many different ways. "International" or "Western" chess itself is one of a family of games which have related origins and could be considered variants of each other. Chess developed from ''chaturanga'', from which other members of this family, such as ''makruk, ouk chatrang'', ''shatranj'', Tamerlane chess, ''shogi'', and ''xiangqi'' also evolved. Many chess variants are designed to be played with the equipment of regular chess. Most variants have a similar public-domain status as their parent game, but some have been made into commercial proprietary games. Just as in traditional chess, chess variants can be played over the board, Correspondence chess, by correspondence, or computer chess, by computer. Some internet chess servers facilitate the play of some variants in addition to orthodox chess. In the context of chess problems, chess variants are called heterodox che ...

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]   |

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. The pin is one of the most powerful chess tactics. 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 fr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

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 ...
