Czech speedcuber and the namesake of the method Jessica Fridrich is. Neither is better. Hide the cases you do not plan to learn. The ultimate motive of this method is to bring down the length of the solutions to blindsolves to the movecounts of solutions using the CFOP method. The first two layers, rather F2L, of the Rubik's Cube, can be solved simultaneously rather than individually. The CFOP method (C ross – F irst 2 Layers – O rienting Last Layer – P ermuting Last Layer), sometimes known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3 Cube.
