3x3 CMLL H Row algorithm

Solve the four upper corners in Roux after building both side blocks; the remaining edges are solved later.

H Row belongs to the H group in CMLL.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: none. 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: U U; R: L B; B: U U; L: B R. The letters identify colors by their reference faces.

Execute the algorithm

U2 Rw U' Rw2 D' Rw U' Rw' D Rw2 U Rw'

The opening is U2 Rw U'; the final segment is Rw2 U Rw'. This version contains 12 face, wide, or slice turns and no whole-puzzle rotations.
