as WV A subset of algorithms for VLS that allows the user to force all upper-face corners to be oriented correctly, or an OLL-Skip, while the last F2L pair is already formed. It is used when the last F2L pair (One corner and its corresponding edge correctly positioned relative to each other) to be inserted is in the top layer, with the 3 top-layer edges oriented correctly. There are a total of 27 cases. WV has an average lower move count than the standard OLL. Short for World Record (e.g. Record for the world). The fastest time in the world for a puzzle to be solved at a WCA competition. Can also be "World Rank" when referring to the rank of a person's record in a database. Completing one or multiple F2L pairs during the cross setup, used almost exclusively in the CFOP method. YouTube Unofficial World Record; the world's fastest time to solve a puzzle that is posted on YouTube, but not having been done at an official WCA competition. ZBLL, short for Zborowski-Bruchem Last Layer (often shortened to ZB), is a set of 177 algorithms (Not including mirrors and inverses) with 493 cases to recognize in order to solve the last layer in one look while all of the top edges are oriented with an average move count of ~12.08. Can be used in any layer-by-layer method that ends in N-Look LL, but will only really be efficient in ZZ and Petrus, as these methods keep edges oriented, whereas methods such as CFOP do not keep the edges oriented, becoming a sometimes 2LLL solve.
