Purpose(s):


ZB (short for Zborowski-Bruchem after its proponents, Zbigniew Zborowski and Ron van Bruchem) is a very efficient but algorithm-intensive method which is a variation of advanced LBL methods such as the Fridrich method. After solving the F2L minus one corner-edge pair in whatever method the solver wishes, there are just two more steps: ZBLS (originally called ZBF2L), which finishes F2L while simultaneously orienting the edges of the last layer, and ZBLL, which finishes the last layer in one algorithm.

ZB averages fewer moves than CFOP and reaches the all last layer edges oriented state without requiring the use of edge control. Unfortunately, because this method has a total of 300 algorithms or 795 total cases, it would take a very long time to learn the entire method. The ergonomics of the ZBLS algorithms are also mostly unknown. Very few people have ever put full ZB into practice so it is unknown how it fares against other methods that have all last layer edges oriented.
