ZB

Zbigniew Zborowski and Ron van Bruchem's method keeps CFOP's cross and first pairs and changes the end: the last pair goes in with ZBLS, which also orients the last layer's edges, and then a single ZBLL algorithm solves the whole last layer. It replaces OLL and PLL with fewer looks and far more algorithms, which is why most solvers take it up piece by piece: ZBLL subsets after a ZZ start or a lucky edge orientation, ZBLS cases as they come.

With three pairs solved, ZBLS inserts the last pair and orients every last-layer edge at once. Many of its cases are an ordinary insertion with a small change that fixes the edges, so it is learnt by understanding how the insertion affects edge orientation as much as by algorithms.

With the edges oriented, ZBLL finishes the last layer in one look. Its subsets are named after the corner orientation shape; the PLL cases are the ones whose corners are already oriented.
