PLLs – 2SR v2.0 (Parity Case Cubing 2014)
This guide deals only with Permuting the Last Layer (PLL) of a 3×3 Rubik’s-style cube. The aim is to make it easier to distinguish each of the 21 PLLs by looking at only two sides (i.e., just one of the four possible angles). This can reduce your time when speed-solving as you will not have to turn the cube to look at the hidden sides.
The guide requires that you can solve the first two layers of a 3×3 cube, can Orient the Last Layer (OLL) to make the top of your cube a solid color, and have PLL algorithms. There are excellent guides to doing all of these things on the web and on YouTube, and I have provided some resources at the back. In addition, I will soon be uploading a guide to doing PLLs from all (or most) angles of each PLL. Also in progress is an F2L guide and a multi-angle OLL guide.
Other cube aficionados have created very helpful guides to recognizing PLLs from just two sides. I put this guide together: to help me learn; to approach and present the material in a way that suits my learning style; and to contribute something to the cubing community. You may have a different learning style and find the other guides easier to use, or may simply find seeing how others conceptualize the same problem useful for improving your recognition. You can’t have too much good information to choose from. The “Credits and Resources” section will help you find those guides.
