Deep Fritz
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. The latest version of the consumer product is Fritz 18 Neuronal. 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 running on a consumer-level microcomputer defeated the mainf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasik Rajlich
Vasik Rajlich (born 1971 in Cleveland, Ohio) is an International Master in chess and the author of Rybka, previously one of the strongest chess playing programs in the world. Rajlich is a dual Czechoslovakian-American citizen by birth; he was born in the United States of America to Czech parents, at that time graduate students, but grew up in Prague. He later spent years in the United States as a student, graduating from MIT. He married Iweta (née Radziewicz) on 19 August 2006. Iweta, who is also an International Master in chess, helps him with the development of Rybka as its tester. In April 2012, the couple was living in Budapest, Hungary and had one child, a son. In April 2012, Rajlich participated in an April Fools' Day prank on ChessBase—claiming by using Rybka he had proven to a "99.99999999% certainty" that the accepted King's Gambit is a draw for White, but only after 3. Be2. Rajlich later admitted on ChessBase, that, "we're still probably a good 25 or so orders o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crafty
Crafty is a chess program written by UAB professor Dr. Robert Hyatt, with continual development and assistance from Michael Byrne, Tracy Riegle, and Peter Skinner.

Swedish Chess Computer Association
The Swedish Chess Computer Association ( sv, Svenska schackdatorföreningen, SSDF) is an organization that tests computer chess software by playing chess programs against one another and producing a rating list. On September 26, 2008, the list was released with Deep Rybka 3 leading with an estimated Elo rating of 3238. Rybka's listing in June 2006 was the first time a program on the list has passed the 2900 mark. In the year 2000 the ratings of the chess engines in the SSDF rating pool were calibrated with games played against humans. The SSDF list is one of the only statistically significant measures of chess engine strength, especially compared to tournaments, because it incorporates the results of thousands of games played on standard hardware at tournament time controls. The list reports not only absolute rating, but also error bars, winning percentages, and recorded moves of played games. The SSDF's current testing platform includes an AMD Ryzen 7 1800X 8-Core 3.6 GHz wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blunder Of The Century
In chess, a blunder is a critically bad move. It is usually caused by some tactical oversight, whether it be from time trouble, overconfidence or carelessness. Although blunders are most common in amateur 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 a double question mark, "", after the move. 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 considered at each move. Neglecting these possibilities leaves a player vulnerable to simple tactical errors. One ...
