X3D Fritz
X3D Fritz was a version of the Fritz chess program, which in November 2003 played a four-game human–computer chess match against world number one Grandmaster Garry Kasparov. The match was tied 2–2, with X3D Fritz winning game 2, Kasparov winning game 3 and drawing games 1 and 4. Match conditions Fritz ran on four Intel Pentium 4 Xeon CPUs at 2.8 GHz. The match was unique in how Kasparov relayed his moves to the computer. In most human–computer matches, the human makes their moves on a normal board, as in a normal game. These moves are fed into the computer by an intermediary seated where a normal human opponent would be, and its replies played on the board by the same person. In this match, however, no normal board and no intermediary was used. Instead, Kasparov, wearing special glasses provided by X3D Technologies Corp, saw a three-dimensional projection of the board floating in the air in front of him. He spoke his moves out loud, thus conveying them to the comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fritz (chess)
Fritz is a German chess program originally developed for Chessbase by Frans Morsch based on his Quest program, ported to DOS, and then Windows by Mathias Feist. With version 13, Morsch retired, and his engine was first replaced by Gyula Horvath's Pandix, and then with Fritz 15, Vasik Rajlich's Rybka. Fritz 17 switched to the Ginkgo engine, written by Frank Schneider. The latest version of the consumer product is Fritz 19. This version supports 64-bit hardware and multiprocessing by default. History In 1991, the German company ChessBase approached the Dutch chess programmer Frans Morsch about writing a chess engine to add to the database program which they sold. Morsch adapted his ''Quest'' program, and ChessBase released it for sale that year as ''Knightstalker'' in the U.S. and Fritz throughout the rest of the world. In 1995, ''Fritz 3'' won the World Computer Chess Championship in Hong Kong, beating an early version of '' Deep Blue''. This was the first time that a program r ...

Paul Keres
Paul Keres (; 7 January 1916 – 5 June 1975) was an Estonian chess grandmaster and chess writer. He was among the world's top players from the mid-1930s to the mid-1960s, and narrowly missed a chance at a World Chess Championship match on five occasions. As Estonia was repeatedly invaded and occupied during World War II, Keres was forced by the circumstances to represent the Soviet Union (1940–41, 1944–75) and Nazi Germany (1941–44) in international tournaments. Keres won the AVRO 1938 chess tournament, which led to negotiations for a title match against the reigning World Champion Alexander Alekhine, but the match never took place due to the outbreak of World War II in 1939. Keres was runner-up in the Candidates Tournament on four consecutive occasions in 1953–1962. Due to these and other strong results, many chess historians consider Keres one of the greatest "Grandmaster (chess), Super grandmasters" in history, and, along with Viktor Korchnoi, the strongest player nev ...

Blunder (chess)
In chess, a blunder is a critically bad mistake that severely worsens the player's position by allowing a loss of , checkmate, or anything similar. It is usually caused by some tactical oversight, whether due to time trouble, overconfidence, or carelessness. Although blunders are most common in beginner games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in chess. What qualifies as a blunder rather than a normal mistake is somewhat subjective. A weak move from a novice player might be explained by the player's lack of skill, while the same move from a master might be called a blunder. In chess annotation, blunders are typically marked with two question marks ("??") after the move notation. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's . In particular, checks, , and need to be considere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brains In Bahrain
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head ( cephalization), usually near organs for special senses such as vision, hearing, and olfaction. Being the most specialized organ, it is responsible for receiving information from the sensory nervous system, processing that information (thought, cognition, and intelligence) and the coordination of motor control (muscle activity and endocrine system). While invertebrate brains arise from paired segmental ganglia (each of which is only responsible for the respective body segment) of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments. All vertebrate brains can be embryonically divided into three parts: the forebrain (prosencepha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
