Dutch Open 2007

[Johannes91]

The chance to get an EO skip is 1:2x2x2=1:8 (and Zbigniew Zborowski knows all 1 step LL algs to handle these!)

Are you sure? A while ago (if I understood correctly) he knew just the cases where edges are solved (EO and EP done).

That would mean there are now at least 2 people who know ZBLL...

BTW, who is the other one?

See message #750 on the Petrus method mailing list.

He knows ZBF2L, too.

If Zbigniew was telling me the truth when I was talking to him in Budepest: yes it is true! He also demonstrated some algorithmes definitely with edges not solved, just oriented. I'm thinking of learning this ZBLL system as well, but just for FMC, not speedcubing.

Zbigniew knows the case if the following conditions are met:

1. Edge orientation is done
2. Edge permuation is done OR 2 edges are swapped in opposite directions (UF and UB or UL and UR)

1. If Edge orientation is not done he made a mistake during his "F2L"
2. If Edge permutation is a 2 or 4 edges diagonally swapped case he doesn't know the 1 look case.

The fact that he doesn't know the case doesn't mean he cannot find/invent it in 1 hour!

Nice to see you again in the DCD.

It has been a really amazing weekend, full of funny moments.

I specially lauged a lot when Arnauld did the pop blindfolded and unsuccessfully tried to find it (sorry for that Arnauld).

Glad to see you again amazing cubist and really kind guys.


And of course, congrats to Mr Akkersdijk for the amazing WR (s), Ernesto and Alejandro for their nice times, Rama for his amazing progression, Ron for his amazing average on 4x4 and efford on the organization, with Ton (also for your multiple BLD), Maria for your kindness and your good results, Joel for your (well deserved) winning, Lars for your awesome way of moving the cube, Gilles for his fast times at everything, Clement for his successful multiBLD and a long list that I don't write but they're in my mind.


Thank you everybody for making these kind of trips unforgetables.

I'm just talking about the speedcubing section (but for sure I also enjoyed too much the marketplace section) (so another long list of people is included in the thank-you-list, you all know I'm glad to meet or to see you again)

Personally, I think I'm really happy with the times I got in competition.

Overall, I got 12 national records. I got personal best on megaminx and 5x5 (my first competition, I do not speedsolve them). 12.63 single solve in competition, and two other 13s solve (unluckily one of them was judged as a DNF since the timer reseted by itself). I also got my unofficial personal best on the 3x3, and my first under 10 second solve, while cubing with Ron and so on in the lobby of the hotel, exactly 9.93, with a PLL skip. I finished fourth in almost all the events, third in the 2x2 and an unexpected fifth place in the 3x3. (Both Ron and Lars are much faster than me).

The only bad thing that has happened is that someone (I hope accidentally) swaped my really-well-turning and new pyraminx for an unscrewed and unplayabled one.

Anyway, and as I told, my remind of this weekend is not my results on the competition but the nice moments I have had with you all.

Thank you and see you soon!

Here is the scramble for Fewest Moves:

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

and for your convenience the inverse scramble:

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

Hi Arnaud,
thanx for the scramble.
I found a nice solution in 20 minutes:
almost F2L: F' D2 L' U' D' R' B2 R D B R2 D2 (11)
preparing LL: D2 R' D B' D B D' R F (9)
8 mover LL: R D F' R F R' D' R' (8)
Total: 28 moves.
I won't miss Dutch open's again...

Hi Guus

That shortens to 26 (cancelling 3 turns between steps 1 + 2. Also it doesn't solve the cube. Obviously some missing turn(s) in that :-o

Greeetz!!

I think Guus tried to write down the solution in a more understandable way. The cancellations were implied.

However, Guus still has problems counting moves because F' D2 L' U' D' R' B2 R D B R2 D2 is not (11).

If I have a cube tonight I will check for the real solution. The trick will be in the R2 D2 D2 R' cancellations.

Hello Per, Arnaud,

Yes, again I made an error breaking down the solution , but this time it was soooo obvious, remove D2 at the end of the first step and the counting will then be right too, 11 turns for this step, so no cancellations are left.

Did you see the 13-move F2L solution in it? But I changed it after move 11.

AFAIK he knows ZZLL. It's not the same to ZBLL.

I have gotten 13 move F2L twice now. Once at the Polish Open, the other time in the previous weekly competition. The first time I also changed it after 11 moves to get a better last layer. The second time I kept it and just did OLL+PLL (which is already 2 skipped steps for me because I only know 10 OLL and 6 PLL for my regular 4 look last layer)

I was once told by a certain FMC-expert that my good beginnings and his continuations would be a winning combination. I don't think you need my good beginnings anymore

However, I think I will beat you at the next official tournament if you don't check the writing of your solution!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
