OLL5 (Square shape)

(l’ U2 L) (U L’ U l) (Square shape at left back corner)

(r’ U2′ R) (U R’ U r) (Square shape at front right corner)

Regrettably there are not good algorithms for “Square shape at right back corner” and “Square shape at front left corner” to coincide with OLL6. So, I chose the above ones which are symmetrical procedures of OLL6.

The right AUF position for OLL5 & OLL6 is that F-face should have no colored piece, or a block “diagonally” in front of the Square shape. Then, move the 2 rows of Square shape toward it to begin the respective algorithms.

I think there are at least following 2 ways to move Back Anti-Sune. The difference is U2 or U2′ turn.

R’ U2′ R U R’ U R beginning with thumb on F-face.

R’ U2 R U R’ U R beginning with thumb on U-face.

I mostly use the precious one, to avoid re-grip at the beginning.
