Touch-move Rule
The touch-move rule in chess specifies that a player, having the move, who deliberately touches a piece on the board must move or capture that piece if it is legal to do so. If it is the player's piece that was touched, it must be moved if the piece has a legal move. If the opponent's piece was touched, it must be captured if it can be captured with a legal move. If the touched piece cannot be legally moved or captured, there is no penalty. This is a rule of chess that is enforced in all formal competitions. A player claiming a touch-move violation must do so before themselves touching a piece. Online chess does not use the touch rule, letting players "pick up" a piece and then bring it back to the original square before selecting a different piece, and also allowing players to premove pieces while waiting for the opponent to move. A player who wants to adjust a piece on its square without being required to move it can announce the French ''j'adoube'' ("I adjust") before touch ...

Swindle (chess)
In chess, a swindle is a ruse by which players in a losing position trick their opponent and thereby achieve a win or draw instead of the expected loss. It may also refer more generally to obtaining a win or draw from a clearly losing position. I. A. Horowitz and Fred Reinfeld distinguish among "traps", "pitfalls", and "swindles". In their terminology, a "trap" refers to a situation where players go wrong through their own efforts. In a "pitfall", the beneficiary of the pitfall plays an active role, creating a situation where a plausible move by the opponent will turn out badly. A "swindle" is a pitfall adopted by a player who has a clearly lost game. Horowitz and Reinfeld observe that swindles, "though ignored in virtually all chess books", "play an enormously important role in over-the-board chess, and decide the fate of countless games". Although "swindling" in general usage is synonymous with cheating or fraud, in chess the term does not imply that the swindler has done anyt ...

Fast Chess
Fast chess, also known as Speed chess, is a type of chess in which each player is given less time to consider their moves than normal tournament time controls allow. Fast chess is subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a particular variation of fast chess in which different rules apply for each of the two players. The top ranked 2021 world rapid chess player is Magnus Carlsen from Norway, who is also the top ranked classical chess player. The top ranked blitz chess player at the beginning of 2022 is Hikaru Nakamura. The top ranked 2021 women's rapid and blitz chess player is Hou Yifan from China, who is also the top ranked women's classical chess player. FIDE rules The World Chess Federation (FIDE) divides time controls for chess into "classical" time controls, and the fast chess time controls. , for master-level players (with an Elo of 2200 or higher) the regulations state that at least 120 minutes per ...

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, which is the most valuable piece. 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 from capture by the opposing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolfgang Unzicker
Wolfgang Unzicker (26 June 1925 – 20 April 2006) was one of the strongest German chess Grandmasters from 1945 to about 1970. He decided against making chess his profession, choosing law instead. Unzicker was at times the world's strongest amateur chess player, and World Champion Anatoly Karpov called him the "world champion of amateurs". Unzicker was born in Pirmasens, a small town near Kaiserslautern in the province of Rhineland-Palatinate noted for shoemaking. His father taught him how to play chess at age 10. His brother, four years older, was also a chess player but was killed in World War II. Unzicker began to play tournaments abroad in 1948 as Germany was struggling to rebuild after the war, and achieved the grandmaster title in 1954. He won the German Championship six times from 1948 to 1963 and tied for first in 1965. From 1950 to 1978 Unzicker played in twelve Chess Olympiads, and was first board on ten of them. He played nearly 400 times representing Germany's nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piatigorsky Cup
The Piatigorsky Cup was a triennial series of double round-robin grandmaster chess tournaments held in the United States in the 1960s. Sponsored by the Piatigorsky Foundation, only two events were held, in 1963 and 1966. The Piatigorsky Cups were the strongest U.S. chess tournaments since New York 1927. Jacqueline Piatigorsky (née Rothschild) was married to cellist Gregor Piatigorsky. One of the strongest woman chess players in the U.S. and a regular competitor in the U.S. Women's Chess Championship, she designed the cup and was the primary organizer of the tournament. The prize funds were among the largest of any chess tournament up to that time. Every player was guaranteed a prize and all traveling and living expenses were paid. Los Angeles 1963 The First Piatigorsky Cup was held in The Ambassador Hotel, Los Angeles in July 1963. The tournament field of eight included players from five countries.

Draw By Agreement
A game of chess can end in a draw by agreement. A player may offer a draw at any stage of a game; if the opponent accepts, the game is a draw. In some competitions, draws by agreement are restricted; for example draw offers may be subject to the discretion of the arbiter, or may be forbidden before move 30, or even forbidden altogether. The majority of draws in chess are by agreement. Under FIDE rules, a draw should be offered after making the move and before pressing the game clock, then marked in the scoresheet as ''(=)''. However, draw offers made at any time are valid. If a player offers a draw before making a move, the opponent has the option of requesting a move before deciding whether or not to accept the offer. Once made, a draw offer cannot be retracted and is valid until rejected. A player may offer a draw by asking, "Would you like a draw?", or similar; the French word ''remis'' (literally "reset") is internationally understood as a draw offer and may be used if the pl ...

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 ...

Opposite-coloured Bishops Endgame
The opposite-colored bishops endgame is a chess endgame in which each side has a single bishop and the bishops reside on opposite-colored squares. Without other besides pawns, these endings are widely known for their tendency to result in a draw. These are the most difficult endings in which to convert a small advantage to a win. With additional pieces, the stronger side has more chances to win, but not as many as when bishops are on the same color. Many players in a poor position have escaped a loss by trading down to such an endgame. These endgames are sometimes drawn when one side has an advantage of two or even three pawns, since the weaker side can create a blockade on the squares on which their bishop operates. General principles Edmar Mednis gives two principles for endgames with bishops on opposite colors: # If a player is down he should look for drawing chances in an endgame with only the bishops and pawns. # With (queen or rook) on the board, having bishops on ...
