The domain name of fmc.mustcube.net seems to have expired.
I found this week's scrambles from google's cache.

FMC round 492
speed: R' B2 U F L B' U F B' U' D2 R L' U R' L' D2 L B' F2 D L2 D' F' L2 R2 B' F' R' L2
1hr/classic: U2 D2 R' B F2 U L' R2 F2 U' B' U2 L2 R D2 F2 L' U B' F2 D U R L' F2 B R' L D' B

Does anybody know the way to contact Per...?

Found two 28s in one hour, maybe I have them somewhere, quite possibly in the trash. Too bad about Fredlund's website though.

Edit:And yes the German forum is great. This week's first scramble is brutal though; I DNF'd like a noob, but ofc Sebastien found a sub-30.

We would love to see more people joining our weekly competition! It doesn't matter if you are not able to speak German, English is also ok!

Well, it also helps that comments are written in this kind of Anglo-Germanic hodge-podge:

dritter mit Limit:
Pre: B2
R’
L U B’ U’ B - Pseudo F2L-2 [6+1/7]
D R2 - 2x2x3 und 3 Pairs [2/9]
F2 L’ F2 L2 D’ L’ F’ D F - Finish [9/18]

Zwei getwistete Corners:
R’ L U . B’ U’ B D R2 F2 L’ F2 L2 D’ L’ F’ D F B2
. = D2 B’ : U’ B D2 B’ U B [8-7/19]
: = B’ U F’ U’ B U F U’ [8-2/25]

Solution:
R’ L U D2 B2 U F’ U’ B U F U2 B D’ R2 F2 L’ F2 L2 D’ L’ F’ D F B2 - 25 Moves

26 Mean

I got the following message from Per.

Hi!

Yes, I am sorry that my FMC site for now is unavailable. I will move to
another host, but which one is not decided as of yet.

Sorry again!

Regards,

Per K Fredlund

Official 35 move solution from Holy Toledo 2014.

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

U2 D F' D' F2 L' D' L B2 F' // double x-cross
D2 F D2 F' R D R2 D // rest of F2L (one move off for OLL cancellation)
R2 D R F' R' F D' R' // OLLCP
B2 D R' L B2 R L' D B2 // EPLL

It was just an efficient CFOP solution with easy cases.

Fixed


My 33 move solution from the same comp.

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

Premove R2

U2 * L' D' L B2 - X-cross
L B' D B L' - double X-cross
D R2 D2 R - F2L -1
D B' D' B D R D R' D R D R' D' - Leave 3 corners
Insert at *: U' R2 U L' U' R2 U L Cancels 3 moves
Solution: U R2 U L' U' R2 U D' L B2 L B' D B L' D R2 D2 R D B' D' B D R D R' D R D R' D' R2 (33 moves)

My (tied) NR solution in IORC:
Scramble: U2 F L U2 B R' U R' D' R' F2 R2 B2 L F2 L U2 F2 U2 B2
Solution: U2 F' D F D F' D F L D' L' B' L2 B L2 U' R' U L2 U' R' U L2 U R B' L' F L

Explanation:
Pseudo 2x2x3 on inv: L' F' L B R' U' (6)
So pre=U2(1)
wth pre U2 for inv and after 2x2x3:
F2l-1: L2 B' L2 B (4)

NISS => Switch to scramble with premoves B' L2 B L2 U R B' L' F L (10)
On scr: F2l-1: U2 (1)
Leave 3 corners: F' D F D F' D F L D' L' (10)

So skeleton is: U2 F' D F D F' D F L D' L' B' L2 B L2 * U R B' L' F L (21)
Insert at *: U' R' U L2 U' R' U L2 (8), no cancellation

I thought I would get something better with that skeleton. Good solve anyway.

Any tips for better leave 3 c?

Hi Pranav,
last 6 moves can be replaced with: L B D' B' L' D, also leaving 3 edges. Cancellations garanteed!

Hmm. Thanks for that!
The other NR holder (Nikhil Mande) also suggested a similar continuation and got an easy 26 with it.

Guess I'll have to work on edge insertions

 

[TeddyKGB]

R U R' F' R U R' U' R' F R2 U' R' U' F' U F U2 R U R'

What is the best way to solve these edges without ruining the 2x2x1 block?

 

[irontwig]

R U R' F' R U R' U' R' F R2 U' R' U' F' U F U2 R U R'

What is the best way to solve these edges without ruining the 2x2x1 block?

To solve edges:
U R F' U' L' U L F U R' U'

To Leave three corners:
U R F' L F L' U' L' U L U R' U'

To solve everything:
R U' R' U2 F' U' F R2 D' R' D R' L U' L' B2

Better solutions might exist, too lazy to check.

Edit: R F2 D R D' R' F' R F' R'

 

[Sebastien]

I just noticed that I currently have a pretty good official Average of 5:

(27), 24, 26, (23), 24 = 24,66

I REALLY want a better official single.

My winning solution from Kansai Open 2014.

Scramble: L2 B2 U' F D2 F L' F2 B D' R2 B' D2 B L2 B' D2 L2
Solution: B' U2 L2 U' B L B' L D2 L' D L' D' L2 B' R2 B L' B' R2 L' B L' D2 L2 B' L2 B' (28 moves)

Spoiler

Here is my start found in a few minutes:

2x2x2 block: B' U2 L2 U'
Pseudo 2x2x3 block: B L B'

By switching to inverse, I found the following backup solution in 20 min. (30 moves)

(Inverse)
Pre-scramble: B L' B' U L2 U2 B

2x2x3 block + EO: B L2 B2 D2 B'
F2L minus 1 slot: D' L
All but 3 corners: D' L D2 L' D L D L' D'
Correction: B L' B' U L2 U2 B
Corner 3-cycle: B L B' R2 B L' B' R2

In the next 20 min., I found the following solution.

(Normal)
Pre-scramble: L2 B' L2 B'

2x2x2 block: B' U2 L2 U'
2x2x3 block: B L B'
F2L minus 1 slot: L D2 L' D L2
All but 3 corners: L D' L * B' L' B L' D2
Correction: L2 B' L2 B'

Insert at *: L B' R2 B L' B' R2 B

I couldn't find any better solution in the remaining time.

A scramble with a free 2x2x2 block, might be interesting to see what people do with it L' D2 L2 R D F' L2 B' F D F R B U L' R2 F2 D2 B2 U' R D2 L2 U2 B2

My winning solution from Kansai Open 2014.

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

Correction: L2 B' L2 B'

Insert at *: L B' R2 B L' B' R2 B

I couldn't find any better solution in the remaining time.

And my second place solution:
B' U2 L2 U' D L' R D R' L B2 D2 B D B D B' D2 L D2 L F' L2 U2 R2 B' R2 U2 L2 (29)

Spoiler

I first noticed that there are only four bad edges in "the R orientation" and even though B F2 R does the EO and sets up a easy first square, I couldn't continue it nicely, so did some good old fashioned block building instead (premoves are L D2 L):

B' U2 L2 U' [2x2x3]
D L' R D R' L [EO]
B2 D2 B [F2L-1/Pseudo F2L]

Here it's easy to leave three corners with D' B2 D2 B' D, but unfortunately they are twisted (IF gives 29 and 30 for insertion of a 3 corner twist (which I don't know) and two corner cycles). Here I switched to the inverse, although it's not needed so for simplicity sake I'll just write it as it would be performed on the normal scramble:

D B D B' D2*[Leaving three edges]
L D2 L [Psuedoness]
F' L2 U2 R2 B' R2 U2 L2 [Edge cycle]

I need to work on my 8-movers though, since *=B L2 U2 R2 F R2 U2 L2 yields 28 moves.

D' B D F L2 D' R' B R B' D2 F2 U2 L2 F2 L' D2 B2 R

D F2 R F2 B' L F'

Anybody have a nice finish?

Couldn't find any good finish for your start but I found a great start to that scramble

Premove F2

2x2x3 - D F
