Düsseldorf
Düsseldorf is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state after Cologne and the List of cities in Germany with more than 100,000 inhabitants, seventh-largest city in Germany, with a 2022 population of 629,047. The Düssel, from which the city and the borough of Düsseltal take their name, divides into four separate branches within the city, each with its own mouth into the Rhine (Lower Rhine). Most of Düsseldorf lies on the right bank of the Rhine, and the city has grown together with Neuss, Ratingen, Meerbusch, Erkrath and Monheim am Rhein. Düsseldorf is the central city of the metropolitan region Rhine-Ruhr, the List of EU metropolitan regions by GDP#2021 ranking of top four German metropolitan regions, second biggest metropolitan region by GDP in the European Union, that stretches from Bonn via Cologne and Düsseldorf to the Ruhr (from Duisburg via Essen to Dortmund).

Computer Chess
Computer chess includes both hardware (dedicated computers) and software capable of playing chess. Computer chess provides opportunities for players to practice even in the absence of human opponents, and also provides opportunities for analysis, entertainment and training. Computer chess applications that play at the level of a Chess title, chess grandmaster or higher are available on hardware from supercomputers to Smartphone, smart phones. Standalone chess-playing machines are also available. Stockfish (chess), Stockfish, Leela Chess Zero, GNU Chess, Fruit (software), Fruit, and other free open source applications are available for various platforms. Computer chess applications, whether implemented in hardware or software, use different strategies than humans to choose their moves: they use Heuristic (computer science), heuristic methods to build, search and evaluate Tree (data structure), trees representing sequences of moves from the current position and attempt to execute ...

Shredder (chess)
Shredder is a commercial chess engine and graphical user interface (GUI) developed in Germany by Stefan Meyer-Kahlen in 1993. Shredder won the World Microcomputer Chess Championship in 1996 and 2000, the World Computer Chess Championship in 1999 and 2003, the World Computer Speed Chess Championship in 2002, 2003, 2004, 2005, and 2007, and the World Chess Software Championship in 2010. The Shredder engine version 10.0 was released in June 2006. Version 11.0 was released in October 2007. Version 12 was released in January 2010. The "Deep" version takes advantage of multiple CPUs or multiple core CPUs. Version 13 was released on 30 October 2016. Version 13 is about 300 Elo better than Version 12. Shredder is one of the few commercial chess programs which is available not only for Windows and Mac OS, but also for Linux. Shredder is also available on the iPhone, the iPad and Android. GNOME Chess is used as the graphical front-end for Shredder. Competition results Shredder ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Computer Chess Championship
World Computer Chess Championship (WCCC) was an event held periodically from 1974 to 2024 where computer chess engines compete against each other. The event is organized by the ''International Computer Games Association'' (ICGA, until 2002 ICCA). It was often held in conjunction with the World Computer Speed Chess Championship and the Computer Olympiad, a collection of computer tournaments for other board games. Instead of using engine protocols, the games are played on physical boards by human operators. The WCCC was open to all types of computers including microprocessors, supercomputers, clusters, and dedicated chess hardware. Due to the requirement to be present on-site, play on a physical board, and strict rules of originality, many strong programs refrain from participating in the ICGA events. As the conditions of the software championship can easily be emulated by anyone with a high-end PC, there are now privately conducted tournaments, such as Top Chess Engine Champions ...

Blitz Chess
Fast chess, also known as speed chess, is a type of chess in which each player is given less time than classical chess time controls allow. Fast chess is subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a variant of fast chess with draw odds for black and unequal time controls, used as a tiebreaker of last resort. As of January 2025, the top-ranked rapid chess player and the top-ranked blitz chess player in the open section is Magnus Carlsen from Norway, who is also the top-ranked classical chess player. The reigning World Rapid Chess Champion is Volodar Murzin of Russia. The reigning World Blitz Chess Champions are Magnus Carlsen and Ian Nepomniachtchi of Russia (who shared victory in 2024). As of January 2025, Ju Wenjun of China is the women's top-ranked rapid player, who is also the reigning Women's World Chess Champion in classical chess and the reigning Women's World Blitz Chess Champion. The women's top-ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess960
Chess960, also known as Fischer Random Chess, is a chess variant that randomizes the starting position of the pieces on the back rank. It was introduced by former world chess champion Bobby Fischer in 1996 to reduce the emphasis on opening preparation and to encourage creativity in play. Chess960 uses the same board and pieces as classical chess, but the starting position of the pieces on the players' is randomized, following certain rules. The random setup makes gaining an advantage through the memorization of openings unfeasible. Players instead must rely on their skill and creativity. Randomizing the main pieces had long been known as ''shuffle chess'', but Fischer introduced new rules for the initial random setup, "preserving the dynamic nature of the game by retaining for each player and the right to castle for both sides".Gligorić (2002), p. 40. The result is 960 distinct possible starting positions. In 2008, FIDE added Chess960 to an appendix of the Laws of Chess. The ...

Universal Chess Interface
The Universal Chess Interface (UCI) is an open communication protocol that enables chess engines to communicate with user interfaces. History In November 2000, the UCI protocol was released. Designed by Rudolf Huber and Stefan Meyer-Kahlen, the author of Shredder, UCI rivals the older "Chess Engine Communication Protocol" introduced with XBoard/WinBoard. In 2002, Chessbase, the chess software company which markets Fritz, began to support UCI, which had previously been supported by only a few interfaces and engines. , well over 300 engines are known to directly support UCI. Design By design, UCI assigns some tasks to the user interface (i.e., presentation layer) which have traditionally been handled by the engine (at the business layer) itself. Most notably, the opening book is usually expected to be handled by the UI, by simply selecting moves to play until it is out of book, and only then starting up the engine for calculation in the resulting position. UCI does not sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Chess People
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...
