2x2 CLL U 2 algorithm

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

CLL U 2 belongs to the U group in CLL.

Recognize this starting position

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

R' F U' R U' R' U2 F2 R

The opening is R' F U'; the final segment is U2 F2 R. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
