From Weekly competition 2011-12:


I found the following skeleton very quickly, maybe within 5 min (still not sub 25, though).
I'd like to team up with you in a competition, ha-ha. :)

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

Pre-scramble: U2 B2 U2

2x2x2 block: L F D L' D (Guus's start)
2x2x3 block: B'
F2L minus 1 slot: R U R' U2
More 2x2x1 block: B' R B
All but 3 corners: R' U R U'
Correction: U2 * B2 U2

Insert at *: D' F2 D B2 D' F2 D B2

Good luck on your next competition, Guus!

wow great solve... how did you get the premoves??

Nothing special. Just think.
With U2, you can see a 2x2x1 block on the B face (after the first 5-move).
B2 compensates for the pseudoness of the 2x2x3 block.
U2 compensates for the pseudoness of the F2L minus 1 slot.
Then I used "U2 B2 U2" for the explanation, but trained FMC players might not need all of the premoves to understand.

French Open Scramble
U2 F' D2 U2 F2 U2 F' L2 R2 F R' D R B2 R' D2 L R' F L2 U

My 27 move solution:
Full solution: B2 U' F2 U B U' F' R' U F2 B2 U B U B L B' U L U L U2 L' U2 L B' L' (27 HTM)
Normal scramble
2x2x2: B' U' F R' U F2
Switch to inverse (PM: F2 U' R F' U B)
Pseudo 2x2x3: L B (use premove B to correct)
Switch back to normal (PM: B' L')
2x2x3: B' . U' F R' U F2 B'
Some EO and make pair: B' U B
Finish EO and make F2L-1: U B L B' U L2
Finish F2L leaving 3 corners: L' U L U2 L' U2 L
Insert B' U' F2 U B U' F2 U at . to cancel 4 moves :)
 
Found this okay skeleton, but the insertions were poop and I couldn't be bothered to look for something different:
Edit: Had a idea, but it didn't lead anything great (31)

B' D R2 F' D B2
U' R' U2:.
F U F U' R2 U2 R' F' U'

.=D B' R' B R D' Conjugated 6 move LL since I saw that D2 brings all the unsolved pieces into the same layer
:=U' L2 U R2 U' L2 U R2

yeah great solve! I definitly can't use premoves -.-''

can you explain how to use them? you seem addicted to premoves! XD
 
There must be a solution to the following conflicting situations.

a) Short optimised scramble where solutions are sometimes being accused of copying parts of the scramble.
b) Long and cumbersome scramble. (Who wants a long solution?)

I think in the old days, the scramble format with repeating parts was working quite well. Who is in favor of returning to this format??

I don't wish to return to the long scramble because it's time-consuming, and becomes mistakable. I know the (A B C)*4 format is better than (A B C D E F G H I) to reduce mistakes and a time to scramble, but still not like it.

Here are samples of my scramble time:

[FMC #100 scramble]
L' R' D R (B2 D2 R B F2)*4 U B R' D2 (L' R2 U' F U')*4 F2 L F B
Mean of 3: 26.97, 24.46, 24.97 = 25.5 (but got a wrong scramble in the 3rd one)

[FMC #200 scramble]
F2 U2 D2 F' B D U' B F R B R' U L D2 L D U' L U2 L' F B2 D2 B' L2 F B2 L' F'
Mean of 3: 13.81, 13.43, 14.22 = 13.82 (all scrambles are correct)

[Weekly competition 2011-01 scramble]
R' U' B2 D2 B' F L U R2 B' U F2 L' F2 R' F2 R' B
Mean of 3: 8.09, 8.28, 8.22 = 8.20 (all scrambles are correct)

As a matter of fact, the time to scramble is one of crucial factors in 1-hour solve, so I don't like the classic way. Doubled-time needed, and mistakable...
 
FMC Nemo Open (Amsterdam) 2 april 2011
scramble: R D2 F2 L2 R' U2 L' B' R' D' U2 L U2 L B2 U2 R' D B2

FMC fail at 38 moves DNF due to a notation error that I could not fix in time.
First 15 min or so was a complete black out, then needed a PLL skip to get to 38 which would still have been 5th place.

Not quite the way I had envisioned my first official FMC.

Then after assisting in the workshops I had another look: 28 HTM in ~ 35 min

Since my inital 4 move 2x2x2 did not have a nice continuation I used it as premoves for the inverse scramble

premoves to make 2x2x2 on inverse scramble; U' R' B L'
then added an additional premove L2 during the solve

premoves: L2 U' R' B L'
F L F' L' D B L B' L D' L B' L' makes F2L and EO minus slot
D B' D B D leaves three corners after 23 moves

Wrote the inverse as solution for the normal scramble and then stickered for insertion:
L . B' R U L2
D' B' D' B D'
L B L' D L' B L' B' D' L F L' F'

At . insert L' F L B2 L' F' L B2 to cancel 3 moves

After the very first move I found an 8 mover with 3 cancellations: total 28 moves
I was too pissed to look for another insertion.

solution:
F L B2 L' F' L B R U L2 D' B' D' B D'L B L' D L' B L' B' D' L F L' F' = 28 HTM

Since my official result was so terrible I'd like to see what the experts can make from my initial 2x2x2 start.

L B' R U makes 2x2x2
and now what...

Have delegates/judges who actually know enough about FMC to not make foolish accusations. All of the accusations I can recall were just ignorance on the part of the judge/delegate on what constitutes actually being related to the scramble.

Bad luck at the competition, you're sure to do better next time.

Adding a L2 into your 4 move 2x2x2 creates a CE pair. Building that into a pseudo block creates another CE pair. Inserting that pair is only 4 moves, where it's probable at least one move will cancel while solving the edges.

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

Which is 15 moves for F2L minus one slot.
 
As posted before, The solution SHOULD be related to the scarmble: it should solve it!!
Actually, as i see it, it is hard to make a solution "related" to the scramble unless it's simply reversal. Of course, unless the scramble is not simply a random sequence of turns ...:tu

I think this solution for Weekly competition 2011-01 scramble (scramble taken from okayama's post) would have to be considered related to the scramble:

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

reverse :D
 
For two weeks in a row now I've been able to solve the first 14 pieces (imo) very efficiently, but then used more than half of the solution lenght to solve the last 6:

D2 U2 L2 U2 F' R' U L2 D2 U2 F' U2 B' R2 U' B D U'
R B2 D' B2 R2 B' L2 D L' R' B' R B2 R (14) [Leaving 2C4E]

U2 R2 D2 U L' F2 U' L U2 B D' L' U R' F' R2 U
B U2 F R' U' D F L' F' L2 B' U' L2 D2 L (15) [Leaving 4C2E]

In both cases 32htm is the number to beat.
 
L' B2 L B' D2 U2 F2 R' F' R2 B' F2 R' F' D2 L F U2 D R' D2 R2 L' D2 F2

I got this while filming 3speed, and had a 10.02 with a triple X-cross.
y L2 D U' R' F D2
U' R2 d' R' F R
y' U R' U'2 R U R' U' R
U L' U' B U L U' r' U' r
U R' U2 R' D' R U' R' D R U R U' R' U' R U'2

47 moves for the full solution, with a very shaky and locky Rperm.
Can someone improve after my start? I'm pretty happy with my 2x2x3 judged basically off inspection. If I found such a short F2L-1 for a speedsolve, I'm sure with some thought it could be a bit shorter, and maybe continuing on green rather than yellow would've been better.

Tried FMC for the first time today. It's hard!

R L U' L' U2 R' L' D L' R U' R2 D L B' U2 D L F R D U' B R' D'

U' L' U B R' L' D' L' (8)
R' U R2 F2 (12)
U' B U' B' F R' F' (19)
R' U' R U R' U' (25)
U' R U2 R' U' (30-1 = 29)

I then spent 15 minutes looking for insertions which ended up messing me up more than not. I'm happy with a 29 move skeleton first try, though!
