2x2 EG1 Pi 2 algorithm

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

EG1 Pi 2 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: B U; R: R R; B: U F; L: U U. The letters identify colors by their reference faces.

The opening is y' R U'; the final segment is R2 U' R'. This version contains 7 face, wide, or slice turns and 1 whole-puzzle rotation.
