2. With limit

L U2 B U B' [Pseudo 2x2x3]

Switch:
B' D' R2 F R' [2x2x3]
F D' F' [Pseudo F2L]
R' D' R2 F' R' F2 D' F2 D2 [L3C]

L U2 B U B' D2 F2 D F2 R F R2 D R F D F' R F' R2 D B.
.=B' R' B L2 B' R B L2

L U2 B U B' D2 F2 D F2 R F R2 D R F D F' R F' R2 D R' B L2 B' R B L2 (28)

I also had 4E in 18 which could (very theoretically) result in 26:
L U2 B U B' F R' D2 R D' F R F' [@1] R' D2 F2 R' B
Insert at @1: F L' F' U2 R' F' R F U2 L
Fewest moves: 26. 2 moves cancelled
The final solution: L U2 B U B' F R' D2 R D' F R L' F' U2 R' F' R F U2 L R' D2 F2 R' B
