2x2 CLL H 2 algorithm
2x2 CLL H 2 algorithm: 11 turns, opening with R U R'. Case recognition, the complete sequence, and practical execution notes.
Solve the final four corners of the 2x2 after completing the first layer.
CLL H 2 belongs to the H group in CLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: L B; R: U U; B: F L; L: U U. The letters identify colors by their reference faces.
Execute the algorithm
R U R' U R U R' F R' F' R
The opening is R U R'; the final segment is R' F' R. This version contains 11 face, wide, or slice turns and no whole-puzzle rotations.
