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.
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.
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.

Fritz and Chesster is a series of introductory chess programs based on the Fritz engine. Each program provides basic tutorials and games based on one aspect of chess, allowing children to learn the basic rules easily without overwhelming them with too many options at once.
Games follow Prince Fritz, the son of King White, and his cousin Bianca, as Chesster the rat (among others) teaches them the fundamentals of chess so that they can defeat King Black.
There are three programs available in the series:
- Learn To Play Chess With Fritz and Chesster covers all the rules of chess, from basic moves to castling and stalemate.
- Learn To Play Chess With Fritz and Chesster 2: Chess in the Black Castle covers chess strategy and tactics, chess openings, and endgames.
- Learn To Play Chess With Fritz and Chesster, part 3: Chess for Winners contains opening schemes, tactics, recognizing checkmates, endgame training, and key squares.
