Smothered Mate
In chess, a smothered mate is a checkmate delivered by a knight in which the mated king is unable to move because it is completely surrounded (or ''smothered'') by its own pieces. The mate is usually seen in a corner of the board, since fewer pieces are needed to surround the king there. The most common form of smothered mate is seen in the adjacent diagram. The knight on f7 delivers mate to the king on h8, which is prevented from escaping the check by the rook on g8 and the pawns on g7 and h7. Similarly, White can be mated with the white king on h1 and the knight on f2. Analogous mates on a1 and a8 are rarer because castling is more common than castling and brings the king closer to the corner. Methods For a smothered mate of this sort to occur in a game, it is usually necessary to sacrifice to compel pieces to smother the king – a player is unlikely to voluntarily surround their king with pieces in a way that makes a smothered mate possible.

Basic Smothered Mate
BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Opening
A chess opening or simply an opening is the initial stage of a chess game. It usually consists of established theory; the other phases are the middlegame and the endgame. Many opening sequences have standard names such as the "Sicilian Defense". ''The Oxford Companion to Chess'' lists 1,327 named openings and variants, and there are many others with varying degrees of common usage. Opening moves that are considered standard are referred to as "book moves", or simply "book". When a game begins to deviate from known opening theory, the players are said to be "out of book". In some openings, "book" lines have been worked out for over 30 moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller ... [...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 natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Israel Horowitz
Israel Albert Horowitz (often known as I. A. Horowitz or Al Horowitz) (November 15, 1907 – January 18, 1973) was an American International Master of chess.

Chess Master
A chess title is a title regulated by a chess governing body and bestowed upon players based on their performance and rank. Such titles are usually granted for life. The international chess governing body FIDE grants several titles, the most prestigious of which is Grandmaster; many national chess federations also grant titles such as "National Master". More broadly, the term "master" can refer to any highly skilled chess player. Over-the-board chess In general, a ''chess master'' is a player of such skill that they can usually beat most amateurs. Among chess players, the term is often abbreviated to ''master''. The establishment of the world chess body, Fédération Internationale des Échecs (FIDE), saw the creation of titles superior to the "national master" titles. In 1950, FIDE created the titles " Grandmaster" and " International Master", the requirements for which were increasingly formalized over the years. In 1978, FIDE created the lesser title of "FIDE Master". Earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palma De Mallorca
Palma (; ; also known as ''Palma de Mallorca'', officially between 1983–88, 2006–08, and 2012–16) is the capital and largest city of the autonomous community of the Balearic Islands in Spain. It is situated on the south coast of Mallorca on the Bay of Palma. The Cabrera Archipelago, though widely separated from Palma proper, is administratively considered part of the municipality. , Palma Airport serves over 29 million passengers per year.

Simultaneous Exhibition
A simultaneous exhibition or simultaneous display is a board game exhibition (commonly chess or Go) in which one player (typically of high rank, such as a grandmaster or dan-level player) plays multiple games at a time with a number of other players. Such an exhibition is often referred to simply as a "simul". Procedure In a regular simul, no chess clocks are used (if they are involved it is called a ''clock simul''). The boards are usually arranged in a large circle or square and the exhibitor walks from board to board in a fixed order. Each individual participant is expected to make a move when the exhibitor arrives at their board. The exhibitor may pause briefly before playing their move, but will typically attempt to avoid lengthy pauses because too many such pauses will cause the exhibition to continue for an extended period. Longer exhibitions increase the risk of fatigue-induced blunders on the part of the exhibitor, especially since the individual participants remaini ...

Alexander Alekhine
Alexander Aleksandrovich Alekhine, ''Aleksándr Aleksándrovich Alékhin''; (March 24, 1946) was a Russian and French chess player and the fourth World Chess Champion, a title he held for two reigns. By the age of 22, Alekhine was already among the strongest chess players in the world. During the 1920s, he won most of the tournaments in which he played. In 1921, Alekhine left Soviet Russia and emigrated to France, which he represented after 1925. In 1927, he became the fourth World Chess Champion by defeating José Raúl Capablanca. In the early 1930s, Alekhine dominated tournament play and won two top-class tournaments by large margins. He also played first board for France in five Chess Olympiads, winning individual prizes in each (four medals and a brilliancy prize). Alekhine offered Capablanca a rematch on the same demanding terms that Capablanca had set for him, and negotiations dragged on for years without making much progress. Meanwhile, Alekhine defended his title w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caro–Kann Defence
The Caro–Kann Defence is a chess opening characterised by the moves: :1. e4 c6 The Caro–Kann is a common defence against the King's Pawn Opening. It is classified as a Semi-Open Game, like the Sicilian Defence and French Defence, although it is thought to be more solid and less dynamic than either of those openings. It often leads to good endgames for Black, who has the better pawn structure. It allows Black to circumvent enormous bodies of theory in 1.e4 openings such as the Ruy Lopez and the Sicilian Defence. Unlike its sister opening, the French Defence, the Caro–Kann does not hinder the development of Black's light-squared bishop. However, it comes at the cost of a tempo because Black has to play 1...c6 before pushing the pawn to c5, whereas Black can push c7–c5 in one move in the French Defence. White can combat the Caro–Kann in several different ways, often gaining a space advantage; additionally, Black has less mobility and can lag in development. In the ...

Shilling
The shilling is a historical coin, and the name of a unit of modern currencies formerly used in the United Kingdom, Australia, New Zealand, other British Commonwealth countries and Ireland, where they were generally equivalent to 12 pence or one-twentieth of a pound before being phased out during the 20th century. Currently the shilling is used as a currency in five east African countries: Kenya, Tanzania, Uganda, Somalia, as well as the ''de facto'' country of Somaliland. The East African Community additionally plans to introduce an East African shilling. History The word ''shilling'' comes from Old English "Scilling", a monetary term meaning twentieth of a pound, from the Proto-Germanic root skiljaną meaning 'to separate, split, divide', from (s)kelH- meaning 'to cut, split.' The word "Scilling" is mentioned in the earliest recorded Germanic law codes, those of Æthelberht of Kent. There is evidence that it may alternatively be an early borrowing of Phoenic ...

Joseph Henry Blackburne
Joseph Henry Blackburne (10 December 1841 – 1 September 1924) was a British chess player. Nicknamed "The Black Death", he dominated the British scene during the latter part of the 19th century. Blackburne learned the game at the relatively late age of 17 or 18, but he quickly became a strong player and went on to develop a professional chess career that spanned over 50 years. At one point he was one of the world's leading players, with a string of tournament victories behind him, and popularised chess by giving simultaneous and blindfold displays around the country. Blackburne also published a collection of his own games. Biography Joseph Henry Blackburne was born in Manchester in December 1841. He learned how to play draughts as a child, but when he was aged 17 or 18, he heard about Paul Morphy's exploits around Europe, and he switched to playing chess: Blackburne joined the Manchester Chess Club in 1861. In July 1861 he lost 5–0 in a match with Manchester's stron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
