Info from the wikipedia:
Fritz is a
German chess program developed by Frans Morsch and
Mathias Feist. Morsch and his friend Ed Schröder produced a chess program in the early 1980s. In the early '90s, the German company
ChessBase asked Morsch to write the Fritz chess programs (called Knightstalker in the USA). In 1995, Fritz 3 won the computer World Championship in Hong Kong, surprisingly beating a prototype version of
Deep Blue.
In
2002, a version of Fritz specifically designed for
multi-processing,
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 the program with a 3D interface, drew a four-game match against
Garry Kasparov.
Fritz is also used in the
Fritz and Chesster series of introductory chess software.
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. On the
September 10,
2006 SSDF rating list, Fritz 9.0 placed sixth with a
rating of 2811, six points below
Shredder 9.0, and 113 points below #1 ranked
Rybka 1.2.
On
October 4,
2006, in the course of the
FIDE World Chess Championship 2006 between
Vladimir Kramnik and
Veselin Topalov, Topalov's manager Silvio Danailov issued a press release including what it labeled "coincidence statistics" between the play of Kramnik and moves recommended by the Fritz 9 software.
[1] Given Danailov's previous characterization of Kramnik's
frequent bathroom visits as "strange, if not suspicious", this was widely interpreted as a tacit accusation of Kramnik cheating through the use of the Fritz software. However, the Danailov press release did not offer Topalov's own percentages for comparison. Moreover, subsequent analysis showed that, using similar statistics, one might imply that the Cuban chess legend
José Raúl Capablanca cheated using Chessmaster 9000 software back in 1918
[2] - decades before the first computers were built.
On
November 25,
2006 Deep Fritz began a six game match against Kramnik in
Bonn. Fritz was able to win 4-2
[3] but Kramnik played surprisingly weak.

The latest version of the
consumer product is Fritz 10.
A
Pocket PC program called
Pocket Fritz is actually based upon
Shredder (chess), a engine written by
Stefan Meyer-Kahlen.
