Lars Petrus is a Swedish speedcuber currently living in Mountain View, California (Bay Area). He is best known for inventing the Petrus Method for 3x3 speedsolving, and for his achievements in Fewest Moves.

Inventor of Petrus method

Main Article : Petrus method

Lars invented his method in the early 1980s, at a time when almost everyone else was using a basic layer-by-layer or corners first method. His method is very intuitive and based on building around a corner, so as to have as many free sides as possible for most of the solve. Because this approach can be very efficient, it is very popular for Fewest Moves solving.

Official Results

Lars won the 1981 Swedish championships using his method, and thus became the Swedish representation for the World Rubik's Cube Championship 1982, where he placed 4th with a best time of 24.57. Lars's current best times in competition for the 3x3 event are a 16.64 second single and a 20.48 second average of 5.

Lars won 3x3 Fewest Moves at the World Championship 2005 with a 38-move solution, making him the World Champion between 2005 and 2007. Lars also broke the 3x3 OH European record several times in 2004 and 2005.
