    Very nice! I wonder what were Yumu's and Oliver's solutions.

    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

    Aww c'mon. You might suddenly get a sub-20 in the next WC and become a WR and WC holder.
     
  7. 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)

    Gus
     
  17. I found a 38 on that one, also posting on request. It was linear Fridrich F2L with COLL and an edge insertion, really the best I could find...

    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?
     
  20. Scramble: R2 D B2 U B2 D B' D' R' U' F' D2 B2 R D L' B' F

    Cross: R2 U2 R' F' (4/4)
    First pair: F' D F R D R' (6/10)
    Second pair: R' D' R L' D2 L (6/16)
    Third pair: L' D2 L2 D L2 D L (7/23)
    Fourth pair: R' D' R D2 R' D2 R (8/31)
    COLL: R D R' D R D2 R' D (8/39)
    Insert somewhere with some canceling moves (can't remember) (10/49)

    11 moves cancel, 2 in the insertion, 9 in the solve.
