3x3 OLLCP53 2 algorithm
3x3 OLLCP53 2 algorithm: 15 turns, opening with y2 R U. Case recognition, the complete sequence, and practical execution notes.
Orient the last layer and solve its corner permutation together; edge permutation may still remain.
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, UB. Reading each side’s upper corner stickers left to right when facing that side gives F: B B; R: U U; B: F F; L: U U. The letters identify colors by their reference faces.

The opening is y2 R U; the final segment is R2 U' R'. This version contains 15 face, wide, or slice turns and 1 whole-puzzle rotation.
