Kadabrium: /* 2LLL Methods */

'''Two look last layer''' is completing the [[LL|last layer]] in two steps or ''looks''. It is usually done using [[OLL]] followed by [[PLL]], but can also be done using [[CLL]] followed by [[ELL]], or any combination of [[orientation]]/[[permutation]] of corners/edges. OLL/PLL is the most popular since it's widely regarded to have the best recognition.

==2LLL Methods==
* [[OLL]]-[[PLL]], the most common method; see [[Fridrich Method]]. (21.5 [[STM]]; 78 algs)
* [[COLL]]-[[EPLL]], not a pure 2LLL because to use COLL the edges must be oriented first, usually in conjunction with the last pair. A bit popular, especially for [[OH|one handed solving]]. (17.3 [[STM]]; 46 algs, 44 excluding [[CPLL]])
* [[CLL]]-[[ELL]], effective, but recognition is a little slower than with OLL-PLL. There are not many users but there is a small chance it will be a runner up because of its effectiveness and the fact that more and more cubers are learning CLL for the [[2x2x2]]. CLL-ELL 2LLL is used in the method [[CFCE]]. (18.26 [[STM]]; 71 algs)
* [[LLEF]]-[[L4C]], same as ELL-CLL, the different names are to avoid confusion. Easy first step but the second has many cases and is ineffective, not popular at all. (19.6 [[STM]]; 99 algs)
* [[EO]]-[[ZBLL]], not widely used as a main 2LLL method and is made up of a large amount of algorithms. However, sometimes this is done if the solver can recognize a case before EO. An example of this in use is by Feliks Zemdegs during his [[WR]] [[3x3]] 6.54 second average of 5. (http://cubesolv.es/solve/1787) (19.75 [[STM]] or 18.08 [[STM]] if dot cases are avoided; 496 algs or 495 if dot cases are avoided)
* [[CPEOLL]]-[[2GLL]], solving first CP+EO then CO+EP. Not the most efficient by either algorithm count or recognition, but since non-[[2-gen]] moves are minimized into a few short algorithms in the first step, it can have some situational advantage during [[one-handed solving]] or 3x3 stage of big cubes. (~21 [[STM]]; 101 algs)
