3. (With Limit)

Really makes me wish I hadn't messed up the first solve so badly.

D' U2 B2 R' // 222 (4)
L2 (L) // 223 (6)
L F' L2 U2 L // EO (10)
U F' U' F' U' F U // 2C (17)

Skeleton: D' U2 B2 L' R' F' ^ L2 U2 L U F' U' F' U' F U % L'
%: U' F' U B' U' F U B (cancels 6)
^: F R F' L F R' F' L' (cancels 5)

Solution: D' U2 B2 L' F' L F R' F' L U2 L U F' U' F' B' U' F U B L'

I checked CubeExplorer, and apparently a 21 is the optimal continuation for the obvious 6-move 2x2x3. 1 away, not bad.

22 Moves.
