Scramble: R' U' F U F U2 L2 B2 D2 F2 D2 B' R B' R' D' F2 L U' R2 U' B2 R' U' F
Solution: D2 F' U' R2 L B' R' B L' B' U2 L U L' U R2 B2 R2 U' R B' L B U (24)

D2 F' U' R2 //222 + pair (4/4)
(U' B' L') //223 + pairs (3/7)
(B R' U R2 B2 R') //F2L (6/13)
(R' U' L U' L' U2 R) //LL1 or 3c -1 move (7-1/19)
(R' B L B' R B L') //LL2 (7-2/24)

I have spent some time on this, but I could not find a good finish:
(L B2 D') //Square
(B' R) //2 pair, (B) makes another square
L2 F D2 R' D2 //223
(L2 B') //Blocks

Optimal finish:
D2 L D2 L U' L' U R' B L' B2 R L2
It makes sense on inverse, and it cancels 2 for 23 final.

I had interesting blocks:

D' F' (B)
maybe (R' F' R2 F2)

D' R F' (B)
(U R' F' R2 F' L')

U L' B F' R //EO
(R2 D' L2 D F2) squares and pair

Scramble: R' U' F D F' D2 F D2 B' R L2 F B2 R2 U' B2 D' R2 U F2 U2 B2 F' R' U' F
Solution: L' F2 D L' D R D' L D' L D L' D2 U2 R D U R' F L D2 U (22)

(U' D2 L' F') //EO + 3 pairs (4/4)
® //Simplify for DR (1/5)
L' F2 //Forget about DR, let's try a square (2/7)
D2 * R //Another square (2/9)
D2 L D L' D2 //Pseudo 223 but meh (5/14)
U2 R U D //Oh well 3c it is (4/18)
* = D' L' D R D' L D R (8-4/22)


I have tried for a while to simplify the <D,R,L> part from move 3 to move 18 of the final solution, but I did not manage. However it was possible to simplify it:

Scramble: D L' D R D' L D' L D L' D2 U2 R D U R'
Solution: U' R' L2 U2 D' L2 B2 R' U F2 D R' D' B2 D2 (15)

I can't make any sense of it...

24, DNF, 22 = DNF
