3x3 CMLL Anti Sune Columns algorithm
3x3 CMLL Anti Sune Columns algorithm: 12 turns, opening with U2 R U. 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.
Anti Sune Columns belongs to the Anti Sune group in CMLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL. Upper edges with that color facing up: UL, UR. Reading each side’s upper corner stickers left to right when facing that side gives F: L R; R: U B; B: U F; L: U B. The letters identify colors by their reference faces.
Execute the algorithm
U2 R U R2 F' Rw F R U' Rw2 F Rw
The opening is U2 R U; the final segment is Rw2 F Rw. This version contains 12 face, wide, or slice turns and no whole-puzzle rotations.
