The search engine is written in highly optimised assembly language. Move generators, evaluation functions and data structures have been designed specially to maximise the effectiveness of the null-move search. Fritz is build around a selective search technique known as the null-move search. It obtained the best computer result in the 1996 man-computer Aegon tournament.

In tournaments against humans and other programs, Fritz has proven to be a tough opponent when defending difficult positions.Р”РЋ997 Fritz won the ICCA chess computer world championship in Hong Kong 1995 beating a prototype of the Deep Blue chess computer. Selective search unavoidably introduces oversights, but these are few. In its latest version, Fritz manages a 10-times speed-up over a version without the null-move search.

Detecting such moves before they are searched to the full depth is an excellent method to speed-up the search. This applies to 95% of the moves in a search. If the position after the null-move does not return a high value in the evaluation function, then clearly the first of the two moves did not contain a threat. As part of its search, Fritz allows one side to move twice (the other side does a null-move). Р”РЋ995 Fritz is built around a selective search technique known as null-move search. Frans Morsch told Chrilly Donninger about recursive null move, who popularized it by his Null Move and Deep Search paper in the ICCA Journal 1993.

Fritz was also a name given to German troops by the British and others in the first and second world wars, equivalent to Tommy, as the British troops were called by German and other troops. The given name Fritz originated as a German nickname for Friedrich, or Frederick (der 'Alte Fritz' was a nickname for King Frederick II of Prussia, and of Frederick III, German Emperor ), as well as for similar names including Fridolin.
