26 for current Weekly FMC
scramble: F U' R B D F2 B R' U' L' U D' B2 F2 D2 U R F' D B2

B2 D' F // roux block
(U2 F' D R' D2) // 2x2x3
(F U F' B' U' B) // EO + square
L2 (U2 L' U L R U' L' U L R' U') // WV to LL skip

Final solution: B2 D' F L2 U R L' U' L U R' L' U' L U2 B' U B F U' F' D2 R D' F U2 (26)

interesting how the roux block just undoes the last 3 moves of the scramble
After a discussion with Yau, we were trying to figure out if a 4-corner skeleton of 2+2Twisted is better than a 2+2Pure Cycle. Or if they are exactly the same.

Not trying to make a clash between us , but the UKers thought that 2+2Twisted has more freedom, but us Dankers (Kit, Ryan, Mark and I) always thought a 2+2Pure was better because of the leniency in being able to have 1-2 or 2-1 where you can still use a comm if you find that it cancels more going the other direction.

Thinking it over, it seems like 2+2Twisted and 2+2Pure both have the same number of combinations of insertions you can find but its easier to look through all of the insertions for a 2+2Pure because you can look at 1-2-X and 2-1-X at the same time.

Is this correct or is there something else we are missing. I was just surprised because I always thought 2+2Pure was a lot better.
2+2twisted has 8 possible combinations of commutators, 2+2pure has 16 because you can do inverses, so I think you're right.
edit: nevermind this is wrong

Yau and I got 24 combinations for each 2+2Pure and 2+2Twisted.

yeah I just redid it and got the same, but I think 2+2pure would be better because for 2+2twisted, having one of the possible comms be an 8 mover would often mean lots of other possibilities at the same position would not be pure 8 movers, while 2+2pure can always have the inverse case done as well

FMC EU 3rd scramble:
L2 U2 B2 F2 U' B2 F2 U' L2 D' U' B' R D' B F R' B' R2 F2

I found this 20-move solution in 80 mins :
L2 D' F B' L U F B' R F L2 U2 F2 B2 D R F2 D2 R' B
( B' R D2 F2 R' D ) orient corners and 4 edges,
L2 D' F B' L U F B' R 4 more edges / domino reduction,
F L2 U2 F2 B2 D2.

Another lucky scramble:
D2 F2 R D2 L2 F2 L' B2 R' U2 F2 D' B2 L' U B' U B D B'
Posted by Robert Yau a few days ago.

My 21-move solution within 1hr:

F2 R' L F2 U' orient corners and 4 edges,

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

2x2x2: L' R2 F2 D2

Can anyone find a shorter solution with this 2x2x2? My best is 29 so far (17 to 2+2, 4 moves cancelled with insertions)
I've tried inserting random D moves between the L' and R2 and I've also tried EO after the 2x2x2 (Do R U or R U' after the 2x2x2). I haven't had much luck.

Here's an interesting 29 with no B moves and <R,F,U> for the last 20 moves

L' R2 F2 D2 // 2x2x2
U2 // pair
(F') // xcross + pair
F' U F U2 R2 // 2x2x3
R' F' R U2 (U2) // F2L - 1
F2 R' F' R F U F2 U' F' // to L3C

L' R2 @ F2 D2 U2 F' U F U2 R F' R U2 F2 R' F' R F U F2 U' F' U2 F

Some people wanted my 23 from FMC Europe so here it is.

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

F2 R2 L F' U' // 2x2x2 with extra move
D' R' D2 // 2x2x3 with D' premove
R' F2 U' R U F' U F' U'// AB3C

F2 R2 L F' ⎀ U' D' R' D2 R' F2 U' R U F' U F' U' D' // Skeleton

⎀ = [F, D B2 D']

Final solution: F2 R2 L D B2 D' F' D B2 D2 U' R' D2 R' F2 U' R U F' U F' U' D' (23, 3 moves cancelled)

Bad results for me at FMC Europe.

Scramble 1: in the last 15 minutes I try to write down a safety 33 moves solution, but I fail. It's my first official DNF in FMC
Scramble 2: I find a nice start and a decent L5C skeleton, but insertions aren't good and I don't bother writing down a solution (the mean is already DNF)
Scramble: U' D' F D L' B R' U F R B' U2 D2 L2 F2 D2 R' F2 R
EO: U2 F U' L D'
2x2x2: R' D2
MAGIC: B' R' B (3 premoves make F2L-1+EO in 13)
I don't remember exactly how, but after this I got all but 5 corners in 19 moves in total, then 7+5 moves for insertions (possibly not even close to optimal)
Scramble 3: a good solve (27)
Scramble: L2 U2 B2 F2 U' B2 F2 U' L2 D' U' B' R D' B F R' B' R2 F2
On normal:
3x2x1: F R' D2 B
On inverse with premoves B' D2 R F'
Square: U
F2L-1 (-1 move): R L2 D' L2
Pseudo F2L: F R F'
2c2e: R U B U' B R2
LL alg: R' F2 L2 D' L' D L' F2 R U'

My (tied) winning solution from Kansai Open 2016.

Scramble: D B2 R2 B2 R2 D' F2 L2 D R B U' F2 L' D' F' R B' F
Solution: D L F D' F' U' F D F' B D' F2 U' R2 U2 R' U' F2 B' D B U2 B' D' B (25 moves)
2x2x1 block: D L *
2x2x2 block: U' B D'
2x2x3 block: F2 U' R
More square: R U2 R'
More square: U'
All but 4 corners: F2 U2
All but 3 corners: U2 B' D B U2 B' D' B

Insert at *: F D' F' U' F D F' U

The skeleton leaves 4 corners with only 13-move, the shortest skeleton that I've found in official competitions so far, but unfortunately I couldn't find any further good insertions.
Nice scramble, and Shuto Ueno also got 25 moves (18-move 3CP skeleton).
Yuhei Takagi got 27-move solution, but DNF because of a notation error.
Hopefully they write their nice solutions here.

Wow only cancelling 4 moves with 4 corners is a bit unlucky? But at least the skeleton is so short and simple

Here is my winning solution from Kansai Open 2016. (Official PB! )

Scramble: D B2 R2 B2 R2 D' F2 L2 D R B U' F2 L' D' F' R B' F
Solution: D R2 U L2 U' R2 U L2 U2 L B L' U L D' U F2 U' D2 L D L' D R U (25moves)

EO: D * U' L B
222: L' U L D'
pseudo F2L-1: U F2 U' R
L3C: R' D2 L D L' D R U

Insert at * = R2 U L2 U' R2 U L2 U'

Skeleton is nice but insert is not good.

I also found 15moves skeleton with 5corners.
EO: D U' L B
222: L' U L D'
223: F2 U' R
pseudo F2L-1: R U R'
L5C: F2 U
But optimal is 27moves

I've been looking for a thread that outlines some FMC techniques as well as the lingo. I've been learning about comms. I finally have figured out what insertions mean. I know most of the heise method. But I've yet to find info on what a skeleton is or its purpose. And also how to use inverse scramble (or even why this is useful or allowed ).

Anyone point me in the right direction?
