2x2 CLL AS 1 algorithm

Solve the final four corners of the 2x2 after completing the first layer.

CLL AS 1 belongs to the AS group in CLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UBL. Reading each side’s upper corner stickers left to right when facing that side gives F: U L; R: U F; B: U F; L: R B. The letters identify colors by their reference faces.

y R U2 R' U' R U' R'

The opening is y R U2; the final segment is R U' R'. This version contains 7 face, wide, or slice turns and 1 whole-puzzle rotation.
