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 Cycle)|
(R U’ R U) (R U) (R U’) (R’ U’ R2)
(R2 U) (R U R’ U’) (R’ U’) (R’ U R’)
It took me about a week to get the algorithms down. As this video shows, the Ua iteration is perhaps my fastest and smoothest algorithm. There are a few Ub perms burried in there; they are fast, but a tad bit choppier.
At the risk of appearing to brag, the slo-mo Ub then Ua at the end shows a facility with finger tricks that I never thought achievable. The Beatles’ “Getting Better” soundtrack is meant as caricature, not boasting.
I’m a few days into the A perm for corner cycling. I’ll post a video about that next weekend, marking the final jettisoning of all things Beginner’s.
