2x2 EG2 Pi 3 algorithm

Solve the remaining 2x2 corners when the completed first face has a diagonal swap in its layer.

EG2 Pi 3 belongs to the Pi group in EG 2.

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: B U; R: F B; B: U F; L: U U. The letters identify colors by their reference faces.

The opening is U F R2; the final segment is R2 F2 U2. This version contains 13 face, wide, or slice turns and no whole-puzzle rotations.
