2x2 ORTEGA/VARASANO TUTORIAL
Example 1
Face green with white on top, and do this scramble:
R' U F2 R' U2 F' R F' U' F
One possible solution is to face the cube as shown (adjacent white stickers on the upper front), and use (R2DR'U'R). R2 the puts 3rd orange in place on the bottom. D prepares to receive the last orange piece. (R'U'R) inserts the final orange piece normally.
The full solve would be 26 moves:
- First Side: (R2DR'U'R)
- Opposite Side: U2 (RUR'U') (R'FRF')
- PBL: x2 (RU'R'U') F2 (U'RUR'D) R2 U'
Example 2
Face green with white on top, and do this scramble:
R U' F2 U' R2 F2 U2 R' U2 R2
One possible solution is to face the cube as shown (adjacent whites on the lower right side) and use (RUR) to complete the red side on the bottom.
The full solve would be 22 moves:
- First Side: (RUR)
- Opposite Side: (RUR'U) (RU2R')
- PBL: x2 U2 (RU2R'U') (RU2L'U) (R'U'R)
Example 3
Face green with white on top, and do this scramble:
F2 R2 U F' U' F R2 F2 U2 F2
One possible solution is to face the cube as shown (orange pair on bottom, face the side with no red) and use (RUR). This completes the red side on the bottom.
The full solve would be 19 moves:
- First Side: (RUR)
- Opposite Side: U2 (RUR'U) (RU2R)
- PBL: U' (R'UR'F2) (RF'R) U2
