3x3 CMLL L Best algorithm
3x3 CMLL L Best algorithm: 9 turns, opening with U' F' Rw. 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 Best 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: R B; R: L R; B: U L; L: F U. The letters identify colors by their reference faces.
Execute the algorithm
U' F' Rw U Rw' U' Rw' F Rw
The opening is U' F' Rw; the final segment is Rw' F Rw. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
