Daily F2L Discussion - Case 13

Sorry for the delay! I plan on making 2 threads tomorrow to make up for it.

Case 13

Setup: R' U R U R' U' R U' y

Most important solution: y' U R' U R U' R' U' R

Angles: Easy from FL + BR. Harder from FR + BL.

Mirror: Case 14

Discussion of Case 13:

This is a very bare-bones, simple, and intuitive case. It is best handled from the FL and BR.

The two top stickers are different (and the corner's top color does not match the cross color), so the general idea is to reduce this case to case 3 by hiding the corner and repositioning the edge. It is simple to do so from the FL or BR, as mentioned previously. For example, from the BR, the algorithm would be U R' U R U' R' U' R. Intuitively, U R' hides the corner, U repositions the edge, and R unhides the corner. The remainder of the algorithm (U' R' U' R) is simply a solution to case 3. If the concept of hiding pieces is new to you, please see this discussion.

The case is equally simple from the FL. For the other two angles, it is best to do a single cube rotation (y or y'), although I've included an alternative set of algorithms that are rotationless (but less intuitive).
