Grotesque (chess)
In chess, a grotesque is a problem or endgame study which features a particularly unlikely or impossible initial position, especially one in which White fights with a very small force against a much larger black army.Hooper & Whyld (1996), p. 160 Grotesques are generally intended to be humorous. Examples Ottó Bláthy A particularly extreme example by Ottó Bláthy is illustrated in the adjacent diagram. In the initial position Black has all sixteen pieces remaining and White has just a single pawn on its starting square, yet it is White who will deliver checkmate. This position in Forsyth-Edwards Notation (FEN) is : 8/8/8/2p5/1pp5/brpp4/qpprpK1P/1nkbn3 w - - 0 1 The solution is: :1. Kxe1 Qa1 2. h3 Qa2 3. h4 Qa1 4. h5 Qa2 5. h6 Qa1 6. h7 Qa2 7. h8=N Qa1 8. Nf7 Qa2 9. Nd8 Qa1 10. Ne6 Qa2 11. Nxc5 Qa1 12. Ne4 Qa2 13. Nd6 Qa1 14. Nxc4 Qa2 15. Na5 Qa1 16. Nxb3 The fact that the black queen must be on a1 rather than a2 when White plays Nxb3 explains why 2.h4 does not work. Simil ...

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 ...

Chess Problem
A chess problem, also called a chess composition, is a puzzle set by the composer using chess pieces on a chess board, which presents the solver with a particular task. For instance, a position may be given with the instruction that White is to move first, and checkmate Black in two moves against any possible defence. A chess problem fundamentally differs from over-the-board play in that the latter involves a struggle between black and white, whereas the former involves a competition between the composer and the solver. Most positions which occur in a chess problem are 'unrealistic' in the sense that they are very unlikely to occur in over-the-board play. There is a good deal of specialized jargon used in connection with chess problems; see glossary of chess problems for a list. Definition The term "chess problem" is not sharply defined: there is no clear demarcation between chess compositions on the one hand and puzzles or tactical exercises on the other. In practice, however, t ...

Endgame Study
In the game of chess, an endgame study, or just study, is a composed position—that is, one that has been made up rather than played in an actual game—presented as a sort of puzzle, in which the aim of the solver is to find the essentially unique way for one side (usually White) to win or draw, as stipulated, against any moves the other side plays. If the study does not end in a mate or stalemate, it should be obvious that the game is either won or drawn, and White can have a selection of many different moves. There is no limit to the number of moves which are allowed to achieve the win; this distinguishes studies from the genre of direct mate problems (e.g. "mate in 2"). Such problems also differ qualitatively from the very common genre of tactical puzzles based around the middlegame, often based on an actual game, where a decisive tactic must be found. Composed studies Composed studies predate the modern form of chess. Shatranj studies exist in manuscripts from the 9th centur ...

Ottó Bláthy
Ottó Titusz Bláthy (11 August 1860 – 26 September 1939) was a Hungarian electrical engineer. In his career, he became the co-inventor of the modern electric transformer, the tension regulator, the AC watt-hour meter. motor capacitor for the single-phase (AC) electric motor, the turbo generator, and the high-efficiency turbo generator. Bláthy's career as an inventor began during his time at the Ganz Works in 1883. There, he conducted experiments for creating a transformer. The name "transformer" was created by Bláthy. In 1885 the ''ZBD'' model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (''ZBD'' comes from the initials of their names). In the autumn of 1889 he patented the AC watt-meter. Student paper read on 24 January 1896 at the Students' Meeting. Early life He attended schools in Tata and Vienna, where he obtained diploma of machinery in 1882. Between 1881 and 1883 he worked at ...

Draw By Repetition
In chess, the threefold repetition rule states that a player may claim a draw if the same position occurs three times during the game. The rule is also known as repetition of position and, in the USCF rules, as triple occurrence of position.Article 14K.2 in Two positions are by definition "the same" if the same types of pieces occupy the same squares, the same player has the move, the remaining castling rights are the same and the possibility to capture ''en passant'' is the same. The repeated positions need not occur in succession. The reasoning behind the rule is that if the position occurs three times, no real progress is being made and the game could hypothetically continue indefinitely. The game is not automatically drawn if a position occurs for the third time – one of the players, on their turn, must claim the draw with the arbiter. The claim must be made either before making the move which will produce the third repetition, or after the opponent has made a move producin ...

Joke Chess Problem
Joke chess problems are puzzles in chess that use humor as a primary or secondary element. Although most chess problems, like other creative forms, are appreciated for serious artistic themes ( Grimshaw, Novotny, and Lacny), joke chess problems are enjoyed for some twist. In some cases the composer plays a trick to prevent a solver from succeeding with typical analysis. In other cases, the humor derives from an unusual final position. Unlike in ordinary chess puzzles, joke problems can involve a solution which violates the inner logic or rules of the game. Self-solving problems Some chess puzzles are not really puzzles at all. In the diagram, White is asked to checkmate Black in six moves. The joke in this case is that, by the rules of chess, White has no choice in the matter; the only legal moves lead directly to the "solution": :1. d4 b5 2. d5 b4 3. axb4 a3 4. b5 a2 5. b6 a1=any 6. b7 Tim Krabbé provides other examples on his chess website. Offbeat interpretations of the r ...

EG (magazine)
''EG'' is a magazine which publishes endgame studies and discusses various aspects of the endgame in chess. The letters "EG" signify "End Game" and also the Latin phrase '' exempli gratia''.Roycroft (1972), p. 111 While many chess magazines include sections for endgame studies, ''EG'' is unique for its exclusive focus. History The magazine was founded by The Chess Endgame Study Circle, a British group of chess endgame study composers and enthusiasts, that formed on 16 March 1965. The eleven members included Robert ″Bob″ Wade, Hugh Blandford, and John Roycroft. Roycroft was the magazine's publisher for the first 102 issues, from July 1965 until 1991. Since then the Dutch company Alexander Rueb Vereniging voor Schaakeindspelstudie (ARVES) has been the publisher, but Roycroft stayed as editor-in-chief thereafter. The current editor-in-chief is Harold van der Heijden. The magazine is focused on endgame studies but in some cases includes practical endgames in articles. Another m ...
