Actually, there isn’t Category 8 in the VLS, and the correct naming is “Winter Variation” or “WV” as an abbreviation.
But I included the WV as if it were one of the VLS categories, because it is the case in which all 3 EP corresponding to the U face is oriented. It is an opposite of the Category “Dot”.
In this page, I will show the algorithms I chose for the 8 cases of the Pattern 1.
I call this pattern “convex”.
As same as the other categories, I position the final F2L pair to the front of the U face. You can slot it in by (R U’ R’) sequence in a normal way.
