3x3 CMLL T Left Bar algorithm
3x3 CMLL T Left Bar algorithm: 9 turns, opening with U' 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.
T Left Bar belongs to the T group in CMLL.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Upper edges with that color facing up: UF, UB. Reading each side’s upper corner stickers left to right when facing that side gives F: R B; R: L U; B: L B; L: U F. The letters identify colors by their reference faces.
Execute the algorithm
U' R U R' U' R' F R F'
The opening is U' R U; the final segment is F R F'. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
