Scramble: F' D R2 D' F2 U L' B' D' U2 R' F2 R U2 L2 U2 B2 L F2 L'
Solution:
L' D L F' // XCross off by M2 U2 M2
R U R' U2 y' R' U' R // Second pair
L' U L U' L' U' L // Third pair
y U' L' U' L U L' U' L // Last pair
R U R' U' R' F R F' // OLL
M2 U2 M2 // Solve cross
U2 R' U L' U2 R U' R' U2 R L // PLL
This is a really good scramble for a beginner at 2x2:U2 F R' U F R' F2 R' U' F'
The solution is just F into Y perm. You can also do F2 and cancel one move since the solution starts with F followed by F.
If you are good at lefty turning, you can instead do a y2 and do F into a lefty Y perm, and since the lefty Y perm starts with F', you cancel two moves, which is fewer moves than the righty version, but is more risky since it is lefty turning.
