2x2 EG1 U 1 algorithm

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

EG1 U 1 belongs to the U group in EG 1.

Recognize this starting position

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

The opening is y U2 R; the final segment is U R' U. This version contains 13 face, wide, or slice turns and 1 whole-puzzle rotation.
