L' D L' B' L2 D F D2 B2 D' F2 U' R2 U' B2 U2 F2

I got this scramble last year when I was practicing 3x3x3 for the world championship. I shared this on facebook and a few people found the optimal solution. I think I got a 15 then gave up because I just simply didn't think the optimal solution would be that low (lower than 15). Turns out optimal is 13.

This was a funny "exercise" :)

First time doing EO in a solve. Pretty weird after that 2x2
D2 R2 L2 U' B2 L2 B2 D R2 D' U2 L' U' R2 B' D2 L2 F R B U'



L' B F' R F' //EO
R U2 R U' R' D' //2x2 + Block
U' = B2 R2 B2 U2 L + U L' U2 //L5C

At = U' B D B' U B D' B'

At + L D2 L' U L D2 L' U'

L' B F' R F' R U2 R U' R' D' U2 B D B' U B D' B R2 B2 U2 L2 D2 L' U L D2 L2 U2

rolls my avg25 to 25.24

Hi all,

here are the solutions of my ridiculous Mean from this weekend:

Scramble: L2 D L2 U B2 U F2 U' F L F2 L' U2 R2 D2 B D L2 F'
Inverse: F L2 D' B' D2 R2 U2 L F2 L' F' U F2 U' B2 U' L2 D' L2

Misc: I was in a rather bad condition during this attempt because of a bad cold I was suffering from this week. This got better during the day, but for this first attempt I had problems to concentrate, causing me to act very unstructured. But don't get me wrong, this is not meant to be an excuse for the rather bad result, just an expression of my annoyance that I did not really feel fit for FMC that morning. Since 31s still happen every now and then, I could have as well gotten the same result if I had been compltely well nonetheless. :)

Here is the solution I still managed to write down eventually:

2x2x2: B R2 F # D'
2x2x3+EO: R' B' U R B R' U2 R2
L5C: U' R' U R U2 B2 * U'

* = B2 D' F D B2 D' F' D
# = F' D2 F U' F' D2 F U

Solution: B R2 D2 F U' F' D2 F U D' R' B' U R B R' U2 R2 U' R' U R U2 D' F D B2 D' F' D U'

31 moves.

However, I probably spend most of the time on this start, as you can tell without any success. If you find something on this, I would be interested in seeing it!

EO: F' B2 U L' B
Domino-Reduction: L' D' R D' R'


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

Inverse:
1x2x2: U R' U2
switch & EO+lots of blocks: B * U' F B' R' B'
F2L-1: U R' F2

Very promising start! I found a lot of possible finishes for insertions, this was my final ending:

L3C: L2 D L2 D' L2 D L D'

* = B' U' F U B U' F' U

Solution: U' F U B U' B' R' B' U R' F2 L2 D L2 D' L2 D L D' U2 R U'

22 moves.


Scramble: D2 R2 U2 R2 F2 U2 F U2 F2 R' B2 R' D2 B F2 D' L D2 F U'
Inverse: U F' D2 L' D F2 B' D2 R B2 R F2 U2 F' U2 F2 R2 U2 R2 D2

Inverse:
Orient 4 edges: L
switch & EO+pairs: R F R'
switch & welcome to blockland: R2 F R2

Again, so much to try here. After some time, I found the following and proceeded right away given that the 3 edges are in a great position for insertion:

switch & 3C3E: F2 D F' U2 B' U' F' L2

Skeleton: R F R' F2 D # F' U2 B' U' F' L2 R2 * F' R2 L'

* = R2 F' B U2 B' F
# = D' F' D B' D' F D B

optimal insertions. :) Actually, even the whole finish starting from the first 7 moves is optimal.

Solution: R F R' F D B' D' F D B F' U2 B' U' F' L2 F' B U2 B' R2 L'

22 moves.

Mean: 31, 22, 22 = 25,00 ;)

Can someone take a look at this scramble? I spent the full hour and couldn't find anything. The best I found was a crazy 14 moves to Tripod LL, but I couldn't find a way to make that work..

F2 U2 F2 U2 L D2 L F2 D2 L2 D2 B' L' R F2 U' L' F2 D' U


D R' B U2 L' //2x2
(B' D2 R B2) //2x2x3
D2 B' D B //wat
R2 D //fix

If I used the tripod alg (F U' R' U R U F' R U R2 U R2 U2 R') it would have been 28. Half the moves being LL...

I had this nice start on the weekly competition scramble. DNF'd because of time (was using the wrong inverse scramble for 20 minutes haha).

(L2 F' D2) //Pseudo 2x2x2
(F' U L' D) //What if I just make a 2x2x2. Wait that's a 2x2x3 and a million blocks.

//Didn't have much time left so I could only try a couple things.
(U2 F R F2 U2 F) //F2L-1
U' R2 U R' F R2 F' R2 //4C (21)

Seems like it could end well, if anyone wants to try it.

I have to post this because it's just stupid :p

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

y' U' B F D F' // EO
U L' D F2 // 2x2x2
y2 R U' R2 U R // Opposite 2x2x2
R2 F2 U R' F2 R' // Attempt to extend the opposite 2x2x2 to 2x2x3 and get really lucky in the process

19 moves to AB3C. IF tells me optimal insertion leads to 26 (meh).

I was just experimenting with EO. I know there are 2 2 movers for EO with green/blue front/back. I just wanted to see if the other orientations were any good. I think normally I would try to sub 5 EO. I made some weird decisions but they paid off. This is not a very serious FMC attempt at all :p

Conor's so good, he's getting records for multiple continents! :p

Thanks for sharing the stats. Germany had a 30.57 average of 23... wow. Also interesting how Russia had the lowest sucess rate by over 30% (edit: didn't see Netherlands, so only by 19%) but one of the best averages.

We had a bad day in the Netherlands during FMC Europe.
No one of the 5 dutch competitors had 3 finishes.
I found solves of 29, 36, 29 moves but.....
But I made notation errors during solve 1, couldn find the error in time and i had to fallback on my backup solve (32 moves).
For the 3th solve I also made notation errors (nerves?) so DNF.
2nd scramble was terrible, hard to find good starts. I came up with bad a linear solve (36 moves).
But on my relaxing sunday I found a smooth 24-move solve in 20min or so:

scramble round 2: U' D' F D L' B R' U F R B' U2 D2 L2 F2 D2 R' F2 R
solve: D R F2 U2 F' R D B D2 B2 U B' D' B U' D2 B R' D R D' B' U L (24)

explanation:
solve on normal scramble: premoves [U L] (found on inverse scramble, makes pair and orient some edges)
D R (orient 2 edges)
F2 U2 F' (2x2x2 block)
R D B D2 B2 (extra edge & corner)
U B' D' B U' (15+2, F2L-1 + EO)
D2 R' D R D' (20+2, 3 corners left)
solve 3 corners at the end: D R' D' R . B . R' D R D'. B' with a funny 8 move cancellation!
undo premoves: U L (24)

^Crazy :D

I also wanted to retry the 2nd scramble and found this:

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

(switch)
F' R2 // Pseudo 2x2x2
(switch)
U R' D B2 // 2x2x2 with extra move
(switch)
L F2 L D L2 D // 2x2x3 +square
(switch)
F (U L' U L B L' B' U2) L // AB3C. I used a L3E+parity alg. I knew I would solve one corner but I skipped another one fortunately.

Skeleton: U R' D B2 F % U L' U L B L' B' U2 L D' L2 D' L' F2 L' R2 F (22)

Insertion: % L' D' L U L' D L U'

Final solution: U R' D B2 F L' D' L U L' D U L B L' B' U2 L D' L2 D' L' F2 L' R2 F (26, 4 moves cancelled)

I used Marcel's start to help me with this :)

After a discussion with Yau, we were trying to figure out if a 4-corner skeleton of 2+2Twisted is better than a 2+2Pure Cycle. Or if they are exactly the same.

Not trying to make a clash between us :p , but the UKers thought that 2+2Twisted has more freedom, but us Dankers (Kit, Ryan, Mark and I) always thought a 2+2Pure was better because of the leniency in being able to have 1-2 or 2-1 where you can still use a comm if you find that it cancels more going the other direction.

Thinking it over, it seems like 2+2Twisted and 2+2Pure both have the same number of combinations of insertions you can find but its easier to look through all of the insertions for a 2+2Pure because you can look at 1-2-X and 2-1-X at the same time.

Is this correct or is there something else we are missing. I was just surprised because I always thought 2+2Pure was a lot better.
