2x2 EG1 S 1 algorithm
2x2 EG1 S 1 algorithm: 10 turns, opening with y2 R U. 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 S 1 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: F U; R: F U; B: R U; L: B L. The letters identify colors by their reference faces.

The opening is y2 R U; the final segment is R2 F' R. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
