==== ZZ ====
The ZZ method (short for "Zbigniew Zborowski") is a modern speedcubing method originally proposed by Zbigniew Zborowski in 2006, and built upon since. The method was designed specifically to achieve high turning speeds by focusing on movement ergonomics and is a combination of a block-building method and a layer-by-layer method. The initial pre-planned step is called EOCross and is the most distinctive hallmark of the ZZ method. It involves orienting all edges while placing the cross pieces. It is also common to build an EOLine, mainly used for one-handed solving, where all edges are oriented and only the front and back cross edges are placed. The next step solves the remaining first two layers using only left, right, top, and bottom face turns, one of the advantages of ZZ. On completion of the first two layers, the last layer's edges are all correctly oriented because of edge pre-orientation during EO. The last layer may be completed using a number of techniques, including those used in the [[Fridrich method|CFOP method]]. An expert variant of this method, ZBLL (Zborowski-Bruchem Last Layer), allows the last layer to be completed in a single step with an average of just over 12 moves but requires a total of 493 algorithms to be learned.<ref name="Bernard Helmstetter's Move Count Statistics">{{cite web|url=http://www.ai.univ-paris8.fr/~bh/cube/|title=Rubik's Cube: Algorithms for the last layer|publisher=Université Paris 8|access-date=2 August 2016}}</ref> Due to the ergonomics of ZZ, rotating when solving will never be needed, unlike in the [[CFOP method]]. The ZZ method has fewer moves than CFOP, with ZZ averaging 53.5 compared to CFOP's 55–60 moves. Because ZZ uses EO, it is very move-efficient, and these techniques are sometimes used in FMC (Fewest Moves Challenge).<ref>{{Cite web|title=ZZ method – Speedsolving.com Wiki|url=https://www.speedsolving.com/wiki/index.php/ZZ_method|access-date=2020-05-22|website=www.speedsolving.com}}</ref>
