Solution:
U’ F’ B’ R’ F B’ R’ D’ L2 U B2 U2 L’ B F’ D R D2 U’ L R’ F B2 R
Explanation:
U’ F’ B’ R’ F B’ R’ orient corners and 5 edges,
D’ L2 U B2 all corners,
U2 L’ B F’ D
R D2 U’ L R’ F B2 R L7E.

I wrote something wrong?

It could be using ’ instead of '

 

[Attila]

It could be using ’ instead of '

Thanks
I changed the letters, working now

 

[Ollie]

I did a good'un

B R2 F' R2 U2 B' F2 D2 B2 U2 L2 D F2 U2 L D2 L' F L D' R2

Spoiler: Solution

R2 L2 U B' L' B' U2 F' R F' // 2x2x3 block + EO
R U' R' U2 R' U' R' * // leave four corners

*insert R U R' D' R U' R' * D to cancel three moves and leave a 3-cycle
*insert D L2 D' R' D L2 D' R to cancel one move and solve

Final solution: R2 L2 U B' L' B' U2 F' R F' R U' R' U2 R2 D' R U' R' D2 L2 D' R' D L2 D' R (27)

Nice one ollie, it's optimal with your skeleton too!

 

[Ollie]

Poo, found an awesome skeleton with NISS, but ran out of time/patience.

U2 D' R B2 D2 B2 F' D U R' U F' D U' L' D' R2 F2 R' B' D F2 R' F L

Spoiler

U' D' F' U D' B R' B L2 // 2x2x3 block
F D R2 D' F R F'* // EO + pseudo block
apply on inverse scramble: [premoves F R' F' D R2 D' F' L2 B' R B' D U' F D U] R2 F R' // solves everything but four corners
apply on normal scramble: [premoves R F' R2] *insert F D F' U F D' F' to cancel one move // leaves three corners
L' U L D' L' U' L D U' // laziness

Final solution: U' D' F' U D' B R' B L2 F D R2 D' F R D F' U F D' F' L' U L D' L' U' L D U' R F' R2 (33)

Must try harder

Edit: oh wow, this gives me a Mo3 of 30.67. Time to take FMC seriously, methinks

 

[penguinz7]

Not great, but it's my first time using an insertion, so that's cool. Critique me.

Spoiler: FMC

F2 L2 U' L2 D' F2 D B2 D R2 F2 L D' U L2 F2 L B U2 L2 F2 U'

U * R U' B2 U L // 2x2 Block 6/6

U' F' L' U' L U F U' // LL 8 /28

Insert at * B2 L' F L B2 L' F' L // Corner Cycle 8/36

Final Solution: U B2 L' F L B2 L' F' L R U' B2 U L B D2 R B2 D' B' x2 R U R' U' R U R U' R' U' F' L' U' L U F U' - 36

Critique me.

You used an extra move here. Don't AUF twice.

 

[penguinz7]

I don't even know how I sub 40 FMC, I make such dumb mistakes..
thanks though.

27, tied PB

B2 L2 R2 F L2 R2 U2 L2 R2 B D2 U' B L D2 L2 R D F D' U'

(D F') // pseudo-2x2x2 on inv
D2 // 2x2x2 on normal
U' * L2 U L' B' U' // xxcross
B2 L' B' L // F2L-1
D' B D B' L B2 L' B2 // L3C

Insert U B' U' F' U B U' F at *, cancelling 2 moves.

 

[penguinz7]

Once again I have a potentially awesome start, but can't find any continuations.. I've tried some NISS and single move insertions, but can't find anything.. You guys got anything?

B2 U2 F2 U R2 U2 L2 F2 U2 B2 L2 B' R D B2 L D B F L2 D'
B2 F' D R' U B // 2x2x2
D R F' x2 // 2x2x3

B2 U2 F2 U R2 U2 L2 F2 U2 B2 L2 B' R D B2 L D B F L2 D'
B2 F' D R' U B // 2x2x2
D R F' x2 // 2x2x3

Probably better finishes out there, but I don't have a cube on me and this was the best I could do with alg.cubing.net

B2 F' D R' U B // 2x2x2
D R F' //2x2x3
B R' B' D2 R D R2 //F2L-1
F L' F L F2 R' D //L5C

23 for L5C definitely isn't spectacular, but I'd use it as a backup skeleton.

There's an opportunity to insert a move before you finish your 2x2x3.

Spoiler: Hint

Choosing R2 solves some EO and leaves a possible 16 move F2L-1, or a 17 move F2L-1 with the final pair made. Maybe NISS will give you something good from that, it's my bedtime now

I did actually try that, but couldn't find anything good... Thanks though!

Stick with Kit's continuation

Stick with Kit's continuation

I literally didn't even see that until now. Thanks Kit!

FMC tied PB of 23 moves. My older 23 was just a NISS solve with FRURUF PLL skip. This however is a lot cooler.

F L B2 R L D B U L B' U B2 D2 B2 L2 D L2 B2 D' L2 D

Inv
F L2 (Square+pair)
Switch
R D' F (1x2x3)
D' B U B U2 (2 more squares and a pair)

Skeleton: R D' F D' B U B U2 ^ D' R' U R2 L2 F' (14)

New skeleton: R D' F D' B U B U2 D B2 D' B' @ D B' D2 R' U R2 L2 F' (20)

@ B D B' U' D L D' L' U D'

Solution: R D' F D' B U B U2 D B U' D L D' L' U B' D2 R' U R2 L2 F' (23)

I'm interested in what Sebastien would do for a skeleton like this It's been a while since I've experimented with inserting algs that affect corners and edges, and I'm really happy that it payed off so well this time

 

[Julian]

Last 5 solves have been 32, 27, 32, 32, 29 = 31.00 ao5

 

[Hssandwich]

I'm not good at FMC at all, but I gave it a go. I don't really know what to do after my EO:

D F2 R2 D L2 D2 L2 B2 L2 D' L D' F D' L2 F L' D' B' F2

B'//2x2
U R' F' R'// pseudo blocky things
U2 F // EO

Cool solution! I might look into this later, but I don't see myself coming up with something better.

I'm not good at FMC at all, but I gave it a go. I don't really know what to do after my EO:

D F2 R2 D L2 D2 L2 B2 L2 D' L D' F D' L2 F L' D' B' F2

B'//2x2
U R' F' R'// pseudo blocky things
U2 F // EO

What kind of scramble is that?

I found this within like 2 minutes:

2x2x2: B'
2x2x3+1x2x2: U R' F' R'
EO: U2 F'
3C3E: R' F2 U' R U R'
Finish: F2 (B R' U' R U R B' R') F2

23 moves.

Edit:

Premove: R2
F2L+OLL: B' U R' F' R' U R U R2 F' R
F-Perm: R' F2 R' F' U' R' U2 F' U' F U' R U F' R

F-Perm cancels 4 moves --> also 23 moves.

lol, hard to believe this is a real scramble

I'm not good at FMC at all, but I gave it a go. I don't really know what to do after my EO:

D F2 R2 D L2 D2 L2 B2 L2 D' L D' F D' L2 F L' D' B' F2

B'//2x2
U R' F' R'// pseudo blocky things
U2 F // EO

You could do...
R' D' F2 D R' //more blocks
which reduces this to 6 unsolved pieces. A premove can turn this into a LL case but I don't know it.
