Bump.

My FMC at the WC2009, which got me 3rd place:

Scramble: D2 B F' D2 U2 F' D' F2 L2 R D2 L U' F' L2 D2 F2 L U2
Solution: B2 R2 U' L2 B' R L' D' F D' L D B' E2 L' D2 L E2 L' D2 B R' D2 R F D2 F' D'
Explanation:
2x2x2 block: B2 R2 U' L2 B' R
X-cross and prepa(i)ring a bit: L' D' F
Next 2 pairs: D' L D B' ... L' B
Leave 3 edges: R' D2 R F D2 F' D'
Insert at ...: E2 L' D2 L E2 L' D2 L, 2 moves cancel.
Very nice! I wonder what were Yumu's and Oliver's solutions.

Hi

Oliver's solve was F L R' B U R' U L B D B L' B D2 B D2 B' D' B2 R F R' B' R F' R' (26)
cross+1st pair: F L R' B U R' U
2nd+3th pair: L B D B L'

Hi folks

Apart from fun I solely came to Düsseldorf for FMC competition

I ended up with a 32-move solution, made a mistake while writing down (and wiping out my 34-move backup solution), no time left to check.
I searched the wrong paths, missed an easy 29-move opportunity (nerves!) and at home I check and find out I was nearby a 26-move solution.

All these solution (32, 29,and 26 movers) were all based on pre-scramble-moves [B2 U' D' F] (last three of them found using the inverse scramble) followed by
F2L minus pair: [U F L B U F' U2 D2 B2] (9+4).
With 20 minutes left I decided to stick on this start because I was sure I would find a sub 30 on it.

But I got nervous, with 15 minutes to go I found a 25 move edge frame:
my start: [pre: B2 U' D' F][scramble][U F L B U.F' U2 D2 B'] (13)
F2L: B' U' L' U L' B (18)
LL edges: D L F L' F' D' L' (25)
at the dot I inserted D'B2 D F2 D' B2 D F2, poorly enough only 1 move cancelled.

But time was almost up and only 2 minutes left to write this solution on the result paper. I checked if I didn't make any writing errors, I didn't but sad enough the original solution contained an error already and there was no time left to check it on a clean cube! Resulting in DNF.

What I should have done is finishing F2L an alternate way (I normally always check, without pressure) which would have given me:
My start: [pre: B2 U' D' F][scramble][U F L B U.F' U2 D2 B2] (13)
F2L: D L B' L2 B (18)
LL: U' L' U L' U' L F' L F U L2 (29)
PS. Last LL-alg is very common for speedcubers (my system and Fridrich)
Still can't beleave I missed this one!

But What I really should have done is apply my nice start on the inverse scramble (so pre-moves and starting moves will be inversed and swapped!):
[pre: B2 D2 U2 F U' B' L' F' U'][inverse scramble] [F' D] (11)
F2L minus pair: U2 B (13)
Last pair+smoothly continue with LL-alg: L U' L F' L' D' L' D L' F L U L' (26)
At home, without nerves, I needed 10 minutes to find this.

After 27 years of waiting to become a world-champion I won't bother waiting another 2 years...

Most important: I had a lot of fun, especially with Maarten, that crazy guy from Israel (Shuka), Yasmine&Peter and many others.

Wow! Impressive solution, Guus!
That last solution was just crazy. I didn't know you could do something like that! Why be so nervous at competitions? Just solve the cube. ;)
Oliver also had a nice solution, but it was not as crazy as yours. Maybe I need to work on my Fridrich.
What happened during your 3x3x3 speed round?

Thanx fanwuq,
My 3x3 speed solves:
1. pop (block on floor), 28 sec.
2. F2L error, 30 sec
3. pop (in middel of alg) followed by alg-error, 32 sec
4. normal solve, 16sec
5. normal solve, 17 sec

Nobody told anybody about our nightmare teamsolves.
- Maarten does white cross, incredibly inefficient F2L and OLL-PLL.
- Guus does green cross, incredibly efficient F2L and CLL-ELL.

In those 2 days I learned almost all algorithms Guus uses, which resulted in DNF'ing teamsolves in the beginning, and a 1:38 in the end!

And Shuka indeed is crazy. He uses a cube with Japanese color scheme of which the brand is unclear, but it turns awesome, he uses a CF method, and he sounds so interested in "normal" methods that it felt like he had been living in a cave for 30 years. :p [/offtopic]

Oh, and I did my FMC solve Erik-style. Come in late, go away as first.

Did you mean to say "I won't mind waiting another 2 years"?

"bother" makes it sound like you're quitting cubing, but I don't get the impression that's what you intended.

I slightly modified the way Oliver did his 4th f2l pair, and ended up with a really easy 25 move solution with an insertion. I suck at finding them, so I'm sure someone better could maybe reduce it even more, seeing that I only cancelled 1 move. My solution is as follows:

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

cross+1st pair: F * L R' B U R' U
2nd+3th pair: L B D B2 L' D' B
4th pair+LL cross: D2 R D2 R'

This leaves a pure commutator of 10 moves. The insertion I found was doing D' L' D R D' L D R' at the *, canceling with the R' of the cross building. Perhaps someone can find a better insertion somewhere.

Wow, that's a nice solution!

Someone might be interested at seeing my 35 moves solution:
2x2x3: F2 U B2 D U R' D2 (7)
cross3pairs: L F' [r2] F' U' L F' U L' F (9)
So far it's good, but then I didn't find anything nice:
Stupid CLS: [u2] R U' R U2 R' U' R U' R2 (9)
OLL: Fw R U R2 U' R' U R2 U' R' Fw' (11)
PLL: skip (0)

Can someone show me a nice LL?

Isn't that a nice 11-move LL already?

Well yes. :rolleyes:
But 9 moves last pair and 11 moves LL isn't the greatest. At least the skip isn't pretty. So maybe I should have asked for a better last slot + LL. Or some magic moves during an earlier pair. I tried a lot of stuff but couldn't find anything better than this. But I usually learn something new from seeing how other people would have continued after the first blocks.

Yeh, of course,

I did mean "I won't mind waiting another 2 years.."

My English is not the level of my cube solves

Hi

After all the easy scrambles, here is a really hard one!
It was the scramble of the Dutch Open 2009 FMC competition october 17 2009:

R2 D B2 U B2 D B' D' R' U' F' D2 B2 R D L' B' F (18)

Winning solution was 35 moves bij Erik and me
(posting solution on request)

My solution for the scramble of Dutch Open:

2x2x2 block: F' R2 F U' L' U' R' (7)

2x2x3 block: U F U' L' F2 L (6)

3rd pair: R D R2 F' R' F (6)

4th pair: D' R D' F D' F' R' (7)

LL: L D' R' D L' D' R D (8)

34 moves, found it in 10 minutes, and still could be shorten with an insertion i guess.

Maarten, Gus! I'd like to see yours.


And here is the scramble of the Hungarian Open 2009: F2 U' B2 D' F2 U2 B' D' B2 U' R U' L U2 B2 L B2 F2

In my opinion it is easy, i bet Gus and other expert guys can find sub-30 easily. I did 31 on this. First 18 moves were quite obvious for me, found it in 5 minutes but then i couldn't find anything useful for like 50 minutes. Last 13 moves found in the 57. minute.

2x2x2 block: F U B L2 B' U L (7)

2nd, 3rd pair: F' D' F D2 F D F' R' F' R' F (11)

4th pair+LL: D L D2 L B' L' B D' B D B' L' D2 (13)

Total: 31

I was happy for finding this and i was even happier when i noticed Milán found an even better one and got a 29 moves solution which he deserved a lot! :)

My solution to Dutch Open scramble, 30 minutes almost linear:
Scramble: R2 D B2 U B2 D B' D' R' U' F' D2 B2 R D L' B' F
Solution: U' L' U' R B' D' L' F2 D2 U L U' F' L F B2 R U' R' U2 R' U' R L U' R' U L' U' R D' F D B2 D' F' D B

Pseudo F2L minus pair: U' L' U' R B' D' L' F2 D2 U L U' F' L F B2 R U' R' (19/19)
edges: U2 R' U' R U' (5/24)
first cycle 3 corners: U L U' R' U L' U' R (6/30)
Second cycle 3 corners: D' F D B2 D' F' D B2 (8/38)
Remove pseudo: B' (0/38)

done while doing my take home examination, I got headache today..
maybe better with insertion, but, I must do another thing (doing my exam again, doh)

What's your solution, Guus and Marten?
