Guus Razoux Schultz
Guus Razoux Schultz is a Dutch cuber best known as the runner-up of World Championship 1982 and for his achievements in Fewest Moves. He is believed to be the inventor of the last layer methods CLL and ELL and he is also a co-inventor of the cross-F2L method for the first two layers.
Razoux-Schultz grew-up in Enschede in the Netherlands. He began cubing in May 1981. In a local speedcubing contest in September 1981 he was second (40 seconds) to Marc Waterman (36 seconds). The Dutch National Finals were held on April 24th, 1982 in Utrecht. Razoux-Schultz won the contest, and entry to the World Championship, with a best time of 29.34 seconds; Waterman was second (30.41 seconds). During this period Razoux-Schultz trained extensively with Waterman. Razoux-Schultz later said: "before I entered these world championships Marc had an average of about 20 seconds, I did about 23 seconds".
The World Rubik's Cube Championship 1982 took place in Budapest on June 5. Razoux-Schultz was at that time a 17-year-old student. Razoux-Schultz finished in 2nd place (behind Minh Thai) with a best time of 24.32 seconds. David Singmaster notes that his technique was "DE, DC & ME together, [then] U", ie. that Razoux-Schultz was the only contestant using F2L.
Razoux-Schultz believes that "most of [the other competitors] were faster than I was." He puts his 2nd-place finish down to the fact that the cubes were "very stiff". This favoured Razoux-Schultz because he had strong fingers and also used a technique with a relatively low move count.
Since 2004 Razoux-Schultz has competed in Dutch, European, and World Championships. He competes mainly in 3x3 Speedsolving and 3x3 Fewest Moves. In the Final round of the Dutch Masters 2008, he gained a World Record in 3x3x3 Fewest Moves, completing the cube in just 27 moves.
He has worked mainly as a software engineer and as an IT Consultant.
