3x3 SBLS U UB algorithm
3x3 SBLS U UB algorithm: 8 turns, opening with U R U2. Case recognition, the complete sequence, and practical execution notes.
Complete the last slot of the second Roux block for this corner-and-edge configuration.
U UB belongs to the Corner on U facing up group in SBLS.
Recognize this starting position
For the front-right target slot in this training state, the DFR corner is at UFR and the FR edge is at UB. Corner sticker directions are D→U, R→F, F→R; edge sticker directions are F→U, R→B. Each arrow reads color reference face → current facing direction. Upper corners with the upper-face color facing up: none.

U R U2 R' U R U' R'
The opening is U R U2; the final segment is R U' R'. This version contains 8 face, wide, or slice turns and no whole-puzzle rotations.
