2x2 EG1 Pi 5 algorithm
2x2 EG1 Pi 5 algorithm: 14 turns, opening with R U' R2. Case recognition, the complete sequence, and practical execution notes.
Solve the remaining 2x2 corners when the completed first face has an adjacent swap in its layer.
EG1 Pi 5 belongs to the Pi group in EG 1.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: none. Reading each side’s upper corner stickers left to right when facing that side gives F: L U; R: B R; B: U B; L: U U. The letters identify colors by their reference faces.

R U' R2 F R U R U' R' U' R' F R F'
The opening is R U' R2; the final segment is F R F'. This version contains 14 face, wide, or slice turns and no whole-puzzle rotations.
