Fritz is a German chess program developed by Gyula Horváth and published by ChessBase. Versions prior to 14 were written by Frans Morsch and Mathias Feist. The latest version of the consumer product is Deep Fritz 14. This version now supports 64-bit hardware and multiprocessing by default.
Morsch and his friend Ed Schröder produced a chess program in the early 1980s. In the early 1990s, the German company ChessBase asked Morsch to write the Fritz chess programs (called Knightstalker in the USA). In 1995, Fritz 3 won the World Computer Chess Championship in Hong Kong, surprisingly beating a prototype version of Deep Blue.
In 2002, Deep Fritz drew the Brains in Bahrain match against the classical World Chess Champion Vladimir Kramnik 4–4.
In November 2003, X3D Fritz, a version of Deep Fritz with a 3D interface, drew a four-game match against Garry Kasparov.
On June 23, 2005, in the ABC Times Square studios, the AI Accoona Toolbar, driven by a Fritz 9 prototype, drew against the then FIDE World Champion Rustam Kasimdzhanov.
From 25 November to 5 December 2006 Deep Fritz played a six-game match against Kramnik in Bonn. Fritz was able to win 4–2. In this match, Kramnik blundered away game 2, allowing a mate in one.
On the September 2010 SSDF rating list, Deep Fritz 12 placed sixth with a rating of 3110, 135 points higher than Deep Junior 10.1, and 103 points lower than No. 1 ranked Deep Rybka 3 x64. Deep Fritz 11 is eighth on the same list, with a rating of 3073.
On the December 2010 edition of the CCRL rating list, Deep Fritz 12 placed sixth with an Elo rating of 3088, 29 points higher than Deep Junior 11.1a x64, and 174 points lower than No. 1 ranked Deep Rybka 4 x64. Deep Fritz 11 is also sixth on the same list, with a rating of 3097. Fritz has not kept up with modern advances, attaining only 14th on the 2013 CCRL rating list and not participating in any world championships since 2004.
The 2013 release of Deep Fritz 14 switched engines from the original author Frans Morsch to Gyula Horváth, author of Pandix. A long time participant in world computer championships since 1984, Pandix was substantially rewritten in 2009, and has been a strong contender since then.
This version of Fritz was designed for personal computers with operating system MS-DOS (Microsoft Disk Operating System),
which was operating system developed by Microsoft in 1981. It was the most widely-used operating system in the first half of the 1990s. MS-DOS was supplied
with most of the IBM computers that purchased a license from Microsoft. After 1995, it was pushed out by a graphically more advanced system - Windows and
its development was ceased in 2000. At the
time of its greatest fame, several thousand games designed specifically for computers with this system were created. Today, its development is no longer continue
and for emulation the free DOSBox emulator is most often used. More information about MS-DOS operating system can be found
