Over the past couple months, I’ve tried to exorcise all remnants of the Beginner’s Method. F2L replaced the corner-first/edge-next approach a while ago, and several OLLs have made top-layer orientation a (generally) single-algorithm affair. But my PLLs were still a bit all over the place. I got to the two-look stage pretty easily (with no illusions about being able to one-look it for a while still), but realized that I was still using the Beginner’s Method algorithm for edge cycling — to wit, F2 U(’) R’ L F2 R L’ U(’) F2. Although I got freakishly quick at that algorithm, it required all sorts of awkward hand movements and lent itself to no finger tricks.
Since almost every one of my solves requires an edge cycle — with H and Z perms or the rare PLL skip as the lone exceptions — this bull-in-a-china-shop algorithm had to go. Enter the U perm:
|U Perm (Edge Cycles)|
(R U’ R U) (R U)(R U’) (R’ U’ R2)
(R2 U) (R U R’ U’)(R’ U’) (R’ U R’)
