He is widely considered to have been one of the greatest chess composer, composers of chess endgame studies.In the introduction to ''Collection of Chess Studies'', Sam Sloan writes "... Trotzky is considered to have been the greatest composer of chess endgame studies ever." He is widely regarded as the founder of the modern art of composing chess studies . Troitsky died of starvation during World War II at the siege of Leningrad, where his notes were destroyed. One of his most famous works involves analyzing the Chess endgame, endgame with two knights versus a pawn, see Two knights endgame#Troitzky line, Troitsky line. John Nunn analyzed this endgame with an endgame tablebase and stated that "the analysis of Troitsky ... is astonishingly accurate" . Compositions Troi ...

Endgame Tablebase
An endgame tablebase is a computerized database that contains precalculated exhaustive analysis of chess endgame positions. It is typically used by a computer chess engine during play, or by a human or computer that is retrospectively analysing a game that has already been played. The tablebase contains the game-theoretical value (win, loss, or draw) in each possible position, and how many moves it would take to achieve that result with perfect play. Thus, the tablebase acts as an oracle, always providing the optimal moves. Typically the database records each possible position with certain pieces remaining on the board, and the best moves with White to move and with Black to move. Tablebases are generated by retrograde analysis, working backward from a checkmated position. By 2005, all chess positions with up to six pieces, including the two kings, had been solved. By August 2012, tablebases had solved chess for almost every position with up to seven pieces, but the positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Theoreticians
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, two ...

Deaths By Starvation
Death is the irreversible cessation of all biological functions that sustain an organism. For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including brainstem, and brain death is sometimes used as a legal definition of death. The remains of a former organism normally begin to decompose shortly after death. Death is an inevitable process that eventually occurs in almost all organisms. Death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die. As of the early 21st century, over 150,000 humans die each day, with ageing being by far the most common cause of death. Many cultures and religions have the idea of an afterlife, and also may hold the idea of judgement of good and bad deeds in one's life (heaven, ...

Irving Chernev
Irving Chernev (January 29, 1900 – September 29, 1981) was a chess player and prolific Russian-American chess author. He was born in Pryluky in the Russian Empire (now in Ukraine) and emigrated to the United States in 1905. Chernev was a national master-strength player and was devoted to chess. He wrote that he "probably read more about chess, and played more games than any man in history."Arnold Denker; ''The Bobby Fischer I Knew and Other Stories''; Hypermodern Press 1995 Chernev's deep love for the game is obvious to any reader of his books. Chess historian Edward Winter commented: :Although Chess Notes items have shown that he sometimes cut corners, he was active at a time when writing and scholarship were not regarded as a natural pairing and when anecdotes and other chestnuts were particularly prevalent. Few were interested in sources. Above all, in the pre-digital age the work of writers in his field was far harder; they could not fill in gaps in their knowledge with ...

Chess Composer
A chess composer is a person who creates endgame studies or chess problems. Chess composers usually specialize in a particular genre, e.g. endgame studies, twomovers, threemovers, moremovers, helpmates, selfmates, fairy problems, or retrograde analysis. Moreover, composers have their own preferred style of composing, allowing their sorting according to composition schools. Some chess composers produce huge numbers of chess compositions, while others try to achieve as much quality as possible and present new works only rarely. It is possible for chess composers to gain official FIDE titles, usually for a given number of problems published in FIDE Albums. For example, Milan Vukcevich was an International Grandmaster of Chess Composition, as well as an International Master player. The WFCC (World Federation for Chess Composition), formerly known as PCCC, is a branch of FIDE regulating the awarding of titles such as International Grandmaster, International master, Master FIDE ...
