Fritz is a German chess program developed by Vasik Rajlich and published by ChessBase.

The latest version of the consumer product is Fritz 15, now based on Rybka. This version now supports 64-bit hardware and multiprocessing by default.

In the early 1990s, the German company ChessBase asked the Dutch chess programmer Frans 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. This was the first time a program running on a commodity PC defeated the supercomputers and mainframes that had previously dominated this event.

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 November 25 to December 5, 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.

In 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.
