2x2 CLL T 1 algorithm
2x2 CLL T 1 algorithm: 8 turns, opening with y' R U. Case recognition, the complete sequence, and practical execution notes.
Solve the final four corners of the 2x2 after completing the first layer.
CLL T 1 belongs to the T 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: F R; R: B U; B: B R; L: U L. The letters identify colors by their reference faces.

y' R U R' U' R' F R F'
The opening is y' R U; the final segment is F R F'. This version contains 8 face, wide, or slice turns and 1 whole-puzzle rotation.
