Lucas Winter is a Canadian speedcuber known as the inventor of the Winter Variation for orienting the last layer corners during insertion of the final F2L slot.
He has only attended one official tournament: at the World Rubik's Games Championship 2003 he finished in 68th place in the 3x3 competition with a best time of 1 minute 5.51 secs.
In 2005 he developed his set of algorithms which he called the Winter Variation. He originally developed it as a variation on the Petrus Method, to be used "after you have completed step 3 in Lars Petrus's method (twisting the edges)."[1] More generally it is now used in conjunction with methods in which the last layer edges are already oriented before insertion of the final F2L block, such as ZZ or Petrus.
From 2009-2010, Lucas developed two alternate methods for solving the last six edges in Corners First methods and the Roux method. The first one starts with placing the UL+UR edges in the DF+DB positions. Then an algorithm is performed to orient all edges while preserving the positions of the UL+UR edges. Finally, the edges are permuted. His second LSE method has two steps. The first step is to solve the UL edge and place the UR edge in its correct position but misoriented. Then an algorithm flips the UR edge and any other misoriented edges while simultaneously permuting the M slice. His LSE methods can be viewed in the External Links section below.
