3x3 CMLL L Good algorithm
3x3 CMLL L Good algorithm: 9 turns, opening with U2 F R'. Case recognition, the complete sequence, and practical execution notes.
Solve the four upper corners in Roux after building both side blocks; the remaining edges are solved later.
L Good belongs to the L group in CMLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UBL. Upper edges with that color facing up: UF, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: L R; R: B L; B: U F; L: R U. The letters identify colors by their reference faces.

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