2x2 EG1 S 2 algorithm

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

EG1 S 2 belongs to the S group in EG 1.

Recognize this starting position

In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: B U; R: F U; B: L U; L: B R. The letters identify colors by their reference faces.

R U R' F2 U F R U R'

The opening is R U R'; the final segment is R U R'. This version contains 9 face, wide, or slice turns and no whole-puzzle rotations.
