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

One of the weirdest scrambles I've ever had xD

My first start was B' L F2 which looks interesting but in the end is utterly useless.

Then I found F' L2 F B' L R' F2 R F, a 9 move pseudo-double-x-cross. I could have ended it with F2, but that caused the last 4 pieces of the F2L to all be stuck in a wrong slot. With some random blockbuilding and fiddling with different endings I found a fortunate LL, resulting in a 29-mover.

So, with a premove F:

F' L2 F B' L R' F2 R F
F U' B U B' R2 F'
F' U2 F U F' U' F
U2 F' U2 F U F' U F
F

With a crapload of cancellations.

F' L2 F B' L R' F2 R F2 U' B U B' R2 F2 U2 F U F' U' F U2 F' U2 F U F' U F2

Last 15 moves are <F,U> xD

Yeah, strange scramble, but anyhow it turned out right for me, got this in ±40 min:

pseudo 2x2x3: B' R U2 L D (5)
F2L and LL corners (lucky!): D' R D B' R2 B' U R2 U2 B U B' R2 D' (17)
To solve edges @ beginning insert R2 B' F D2 F' B, 2 moves cancel (21) ;-)

Hi Guys,

Here's the FMC scramble @ Euro 2010

It's rather:

And your solution, Gus?

 

[kidrock2007]

i want know scramble of WCA (FMC) ever year (sorry i 'm vietnamese)

 

[Goater]

Regarding to:

Scramble: U F2 D B2 U' L2 B2 L2 D2 R2 U2 L F L B' U2 F' L2 U' R' U

Not so hard scramble, but I failed in time-scheduling (no time to search a good insertion). :fp
25 moves 3-corners-left skeleton.

and:

Hi Tomoaki,

The best that came up to me within the hour was:
D B D' R2 L2 U F' U' R L B' D2 L U' L' D2 L U L R F2 L' D' F L' F2 L D' F' (29)

With premoves [D2 F'] I made a skeleton : *R' L' B' + L2 R F2 L' D' F L' F2 L D.D2 F' (14) with 3 edges and 3 corners unsolved
to solve edges at * insert: D B D' R2 L2 U F' U' R2 L2 (+8)
to solve corners at + insert D2 L U' L' D2 L U L' (+7)

Not great insertions but spend 30 minutes to find someting better with no result, they're probably optimal.

Gus

Gus... I love your skeletons and insertions, but this time insertions are really weak. Why didn't you end up with pairs-3-cycle?
I.e. like this (found almost linear on your skeleton): F' R2 D [R' D2 R, u] D' R2 F

 

[kinch2002]

This is the Asian Champs scramble: U F2 D B2 U' L2 B2 L2 D2 R2 U2 L F L B' U2 F' L2 U' R' U
I did an almost linear solution quickly and it wasn't bad considering, and I like the ending (even though it's not great) so I thought I'd post it. I went back after a few moves to do a premove, and then went linear. Can't be bothered to look for a better solution right now

Premove: R2
2x2x2: F2 D2 F R B2 D' (The B2 preserves the pair) [6]
2x2x3: R2 B2 R [9]
F2L-1: U B' L U L' [14]
F2L and EO (i.e. ZBF2L I guess!): U' R' U' R B U B' R' U' R [24]
Finish: R U' L' U B2 U B2 U' B2 L R' [34]
Premove cancels off, so it's 34 moves
This is actually the same alg as I finished with in the weekly comp last week (40), it's just one that I happen to know for LL.

Yeah, I thougt I could do insertions in 11 - 13 moves (but it ended up in 15) and skipped other options too quick, after the hour I als found R D' R' D B' D B D B' D2 B (25 moves total) to end with.

Hey can you give the complete time line of your solve? I mean how quickly can you do your solutions. I can get 30-40 moves but never in an hour. I recently went to a competition and could only just figure out the skeleton at the end of 40 minutes. I panicked and screwed up the solve.

@Gus
Can you tell how you schedule your solves? How much time do you take to get your "awesome" skeletons?

 

[guusrs]

@Gus

No, it's a secret

Spoiler

actually it's random, but I write the first solve down as a backup solve

Gus

 

[vcuber13]

are ms 1 or 2 moves?

 

[irontwig]

Slice moves are counted as two moves, if that's what you mean.

 

[guusrs]

scramble: L D2 B' D2 B R' B' U B L B L2 B2 U2 F2 U R2 D' B2 D' B2

It's rather:

All but 3 corners: L2 U' R' U L U' L' R U2 L' U'
3 corners: [D2, R' U' R] at # (cancels 4 moves)

And your solution, Gus?

So someone is interested in my backup solution?
Here it is: L D B2 D' B L' B' U B' F U F' D' F U' F' D R F' L' F R' F' L R' D R D' F' U F2 U2 R U R' (35)

explanation:
2x2x3: L D B2 D' B L' B' U B'
switch to inverse scramble with premoves [B U' B L B' D B2 D' L']:
F2l-1: R U' R' U2 F2 U (6+9)
all BUT 4 corners: F D R' D' R F (12+9)
last 4 corners: F' L' F R F' L F R' + D' F U F' D F U' F' (26+9)
pre-move correction: B U' B L B' D B2 D' L'
got this in ±10 min but wrote down the last corner cycles at the last 5 minutes of the hour.

Now I look at the scramble again and found (in another 20 minutes):
F' U' F U L U L' U' L R U' R U R' U2 R' B' L B2 D R D' L' D R' D' F' R'

I've also looked at the scramble again and also found 22 + 8 - 2 solution (in another 20 minutes)
EO: z B D R' U' F (5)
Something: U' L' U' L' U (10)
Something more: R' D' L' D' # L (15)
All but 3 corneres: R2 D2 R D R' D R (22)
Corners: [D2, R' U' R] at # (28)

However... I know, Gus, that you don't like my beginning-with-EO solutions, do you?

@ AC scramble
I inverted the scramble, and got this solution, which I inverted afterwards. Tim Major wanted me to post this.

2x2x3: z L R2 U' B' U2 B' D' F B' U B (11)
Finish F2L: U' F U' F' R2 D R D' R U' F2 U (23)
Then the OLL which was 9 moves.

Hi Faz,

Congratz with you FMC-result!
Do you know about insertions? Because you could have saved a couple of moves by that! After some exercise you could do that in 5 min or less.
