Perpetual Check
In the game of chess, perpetual check is a situation in which one player can a draw by an unending series of checks. This typically arises when the player who is checking cannot deliver checkmate, and failing to continue the series of checks gives the opponent at least a chance to win. A draw by perpetual check is no longer one of the rules of chess; however, such a situation will eventually allow a draw claim by either threefold repetition or the fifty-move rule. Players usually agree to a draw long before that, however. Perpetual check can also occur in other forms of chess, although the rules relating to it might be different. For example, giving perpetual check is not allowed in shogi and xiangqi, where doing so leads to an automatic loss for the giver. Examples In this diagram, Black is ahead a rook, a bishop, and a pawn, which would normally be a decisive advantage. But White, to move, can draw by perpetual check: : 1. Qe8+ Kh7 : 2. Qh5+ Kg8 : 3. Qe8+ etc. The same po ... [...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 ...

Interzonal
Interzonal chess tournaments were tournaments organized by the World Chess Federation FIDE from the 1950s to the 1990s. They were a stage in the triennial World Chess Championship cycle and were held after the Zonal tournaments, and before the Candidates Tournament. Since 2005, the Chess World Cup has filled a similar role. Zonal tournaments In the first year of the cycle, every FIDE member nation would hold a national championship, with the top players qualifying for the Zonal tournament. The world was divided into distinct zones, with the USSR, United States and Canada each being designated a zone, thus qualifiers from these three zones went directly to the Interzonal. Smaller countries would be grouped into a zone with many countries. For example, all of South America and Central America combined originally formed one zone. Interzonal tournaments The top players in each Zonal tournament would meet in the Interzonal tournament, which would typically have between 20 and ...

Corus Chess Tournament
The Tata Steel Chess Tournament is an annual chess tournament held in January in Wijk aan Zee, the Netherlands. It was called the Hoogovens Tournament from its creation in 1938 until the sponsor Koninklijke Hoogovens merged with British Steel (1967–1999), British Steel to form the Corus Group in 1999, after which the tournament was called the Corus Chess Tournament. Corus Group became Tata Steel Europe in 2007. Despite the name changes, the series is numbered sequentially from its Hoogovens beginnings; for example, the 2011 event was referred to as the 73rd Tata Steel Chess Tournament. Top grandmasters compete in the tournament, but regular club players are welcome to play as well. The Masters group pits fourteen of the world's best against each other in a round-robin tournament, and has sometimes been described as the "Wimbledon Championships, Wimbledon of Chess". Since 1938, there has been a long list of famous winners, including Max Euwe, Bent Larsen, Tigran Petrosian, Pau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Kramnik
Vladimir Borisovich Kramnik (russian: Влади́мир Бори́сович Кра́мник; born 25 June 1975) is a Russian chess grandmaster. He was the Classical World Chess Champion from 2000 to 2006, and the undisputed World Chess Champion from 2006 to 2007. He has won three team gold medals and three individual medals at Chess Olympiads. In 2000, Kramnik defeated Garry Kasparov and became the Classical World Chess Champion. He defended his title in 2004 against Peter Leko, and defeated the reigning FIDE World Champion Veselin Topalov in a unification match in 2006. As a result, Kramnik became the first undisputed World Champion, holding both the FIDE and Classical titles, since Kasparov split from FIDE in 1993. In 2007, Kramnik lost the title to Viswanathan Anand, who won the World Chess Championship 2007 tournament ahead of Kramnik. He challenged Anand at the World Chess Championship 2008 to regain his title, but lost. Nonetheless, he remained a top player; he ...

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 ...

Carl Hamppe
Carl Hamppe (1814 in Switzerland – 17 May 1876, in Gersau, Canton of Schwyz) was a senior government official in Vienna as well as a Swiss-Austrian chess master and theoretician. He played matches with Johann Löwenthal (4 : 5) in 1846, Ernst Falkbeer (16 : 15) in 1850, and Daniel Harrwitz (2 : 5) in 1852 and (½ : 3½) in 1860. Hamppe twice won the Vienna championship (''Wiener Schachgesellschaft'') in 1859 and 1860, both times ahead of Wilhelm Steinitz. His most famous game was the "Immortal Draw" (Carl Hamppe vs. Philipp Meitner, Vienna 1872). He made contributions to the Vienna Game (1.e4 e5 2.Nc3), and two variations in the Vienna Gambit: Hamppe–Allgaier Gambit (1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.h4 g4 6.Ng5) and Hamppe–Muzio Gambit (1.e4 e5 2.Nc3 Nc6 3.f4 exf4 4.Nf3 g5 5.Bc4 g4 6.0-0 gxf3 7.Qxf3).

Pawn Structure
In a game of chess, the pawn structure (sometimes known as the pawn skeleton) is the configuration of pawns on the chessboard. Because pawns are the least mobile of the chess pieces, the pawn structure is relatively static and thus plays a large role in determining the strategic character of the position. General observations Weaknesses in the pawn structure, such as isolated, doubled, or backward pawns and , once created, are usually permanent. Care must therefore be taken to avoid them (but there are exceptions—for instance see ''Boleslavsky hole'' below). In the absence of these structural weaknesses, it is not possible to assess a pawn formation as good or bad—much depends on the position of the pieces. The pawn formation does determine the overall strategies of the players to a large extent, however, even if arising from unrelated openings. Pawn formations symmetrical about a vertical line (such as the ''e5 Chain'' and the ''d5 Chain'') may appear similar, but they te ...

Queen (chess)
The queen (♕, ♛) is the most powerful chess piece, piece in the game of chess. It can move any number of squares vertically, horizontally or , combining the powers of the Rook (chess), rook and Bishop (chess), bishop. 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 ...
