Valerian Onițiu
Valerian Oniţiu (also Valeriu Oniţiu) (April 8, 1872, Sibiu, Romania – 31 December 1948, Timișoara) was a Romanian chess problemist. Oniţiu composed all types of problems particularly fairy chess problems. Oniţiu has ten chess problems in FIDE Albums. Onitiu also did significant work on knight's tours. First in Problemist Fairy Chess Supplement (vol.1 no.12 Jun 1932 p.74) problems 452-455 he gives tours with ten three-unit lines. The editor T. R. Dawson states: "V. Onitiu writes to me that he has examined all possible cases, some 1330 in all, and is convinced that only six of them admit tours, namely Dr Hogrefe's , mine, and the following four new ones. Second in Fairy Chess Review (vol.4 no.3 Dec 1939 p.43 problem 4135, with solution in no.6 Jun 1940 p.93.) he gives a symmetric tour with squares in a knight chain. The editor states: "VO notes that he examined 144 dispositions of the squares, all that are possible for diametral symmetry, and this is the only case leading ...

Chess Problem
A chess problem, also called a chess composition, is a puzzle created by the composer using chess pieces on a chessboard, 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 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 substantial amount of specialized jargon used in connection with chess problems. Definition The term chess problem is not sharply defined: there is no clear demarcation between chess compositions on the one hand and puzzle or tactical exercises on the other. In practice, however, the distinction is very clear. There are common c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chess Composers
Chess is a board game for two players. It is an abstract strategy game that involves no hidden information and no elements of chance. It is played on a square board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw. The recorded history of chess goes back to at least the emergence of chaturanga—also thought to be an ancestor to similar games like and —in seventh-century India. After its introduction in Persia, it spread to the Arab world and then to Europe. The modern rules of chess emerged in Eur ...

PDB Server
This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to play games of chess from the beginning against an opponent. This is usually distinct from actually playing and analyzing games of chess. Many chess playing programs also have provision for solving some kinds of problem such as checkmate in a certain number of moves ( directmates), and some also have support for helpmates and selfmates. Software for chess problems can be used for creating and solving problems, including checking the soundness of a concept and position, storing it in a database, printing and publishing, and saving and exporting the problem. As such they can not only solve dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knight's Tour
A knight's tour is a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. If the knight ends on a square that is one knight's move from the beginning square (so that it could tour the board again immediately, following the same path), the tour is "closed", or "re-entrant"; otherwise, it is "open". The knight's tour problem is the mathematical problem of finding a knight's tour. Creating a program to find a knight's tour is a common problem given to computer science students. Variations of the knight's tour problem involve chessboards of different sizes than the usual , as well as irregular (non-rectangular) boards. Theory The knight's tour problem is an instance of the more general Hamiltonian path problem in graph theory. The problem of finding a closed knight's tour is similarly an instance of the Hamiltonian cycle problem. Unlike the general Hamiltonian path problem, the knight's tour problem can be solved in linear time. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairy Chess
Fairy chess is the area of chess composition in which there are some changes to the rules of chess. It may involve changes to the board, pieces, or rules to express an idea or theme impossible in orthodox chess. An altered piece used in fairy chess is known as a fairy chess piece. The term ''fairy chess'' was introduced by Henry Tate in 1914. Thomas R. Dawson (1889–1951), the "father of fairy chess", invented many fairy pieces and new conditions. He was also problem editor of '' Fairy Chess Review'' (1930–1951). Although the term ''fairy chess'' is sometimes used for games, it is more usually applied in the context of problems. Variations on chess intended to create complete, playable games are more typically referred to as ''chess variants''. Types of fairy chess problems Types of changed rules in fairy chess problems include: * ''New stipulations:'' The alterations most used by fairy chess players, like Thomas Dawson, are new stipulations about mate instead of a direc ...
