Deep Fritz is a multi-processor version of the computer chess engine Fritz written by Frans Morsch and Mathias Feist.
In October 2002, a version of Deep Fritz running on a Compaq 8-processor machine competed with Vladimir Kramnik in the Brains in Bahrain eight-game match, which ended in a 4 - 4 draw, with two wins for each participant and four draws.
As of October 2002, Deep Fritz is believed to be the most powerful computer chess program in the world, defeating Deep Junior, another powerful computer chess program, in a run-off. Whilst it lacks the special-purpose hardware of Deep Blue and consequently can evaluate far fewer positions in a given amount of time, the designers and Vladimir Kramnik, in pre-match interviews, both regarded it as a stronger player. Kramnik, for instance, tried the machine by setting up the positions in the Garry Kasparov-Deep Blue match of 1997, and found that Fritz came up with what he regarded as stronger moves. A direct comparison is impossible as after Deep Blue defeated Kasparov it was disassembled.
In November of 2003, a version of Deep Fritz running with 3D software, X3D Fritz, played a four game match against Kasparov, the highest rated player at the time. The match ended tied after a win by each side and two draws.
