Three posts for all of 2015. That was it. Three. That wasn’t some fancy Rule of Three dramatic device. Not at all. Just. Plain. Busy. There were months at a time that I didn’t even pick up a cube, let alone post. But never fear: In the infamous* words of John Hartford, I’m still here.
This one relates to OLL 56, one of the bar or I-shaped OLLs. As I learn the full set of bar OLLs this emerged as one where the standard alg —
(r U r') U (R U' R') U (R U' R') (r U' r') — could be improved by an M-slice. Yes, I’m a self-proclaimed M- and S-slice evangelist. And, yes, I’ll admit that sometimes using the middle slices is more neat and clever than ultimately useful. (The S-slice alg for F2L edge flip probably should be Exhibit 1.) But OLL 56 really does get easier with an M slice dropped in. Here’s a video showing the execution at full-speed and in slomo:
It may not be for everyone, but it’s much easier for me. Full bar OLL tutorial coming soon....
