Week 51 scramble

3x3x3 Fewest Moves (week 51 scramble!)
1. B D2 R' U2 B D2 R U D' R' B' L2 U2 F' D2 B U2 F L2 U2 F

U2 L D2 B' F D' // 2x2x2 used B' to orient the FR-edge
U2 B' R // 2x2x3
U B U2 L' B // 3rd pair skipped L because of 4th pair.
L2 U L' // F2L Here I switched from blockbuilding to F2L (17 moves)
f RUR' U' RUR'U' f' // OLL (27 moves)
B2 F R F' L2 F R' F' L2 B2 // A-perm L3C (37 moves)

Basicly my first complete solve, didnt look at the time, but it was over 1 hour for sure.
The beginning was quite promising. In the end I messed up. 20 moves LL isn't what I see in this thread..
When I have time, I will take a look at the BH-tutorial. Hope that will help.

Nice beginner solve. You must not complete F2L until an easy LL (<9 moves) is there.Also, you could have done the A perm (Corner 3 cycle) in the middle of the solve causing move cancellation.

Thanks. I was aiming for F2L-1 when I saw the last pair was 3 moves away. Maybe it would have been better to orient the edges and leave the corners.
I will definitely take a look at insertions and find myself a bunch of stickers :)

Here is my winning 29.67 mean from Carnegie Mellon Winter 2014

Scramble #1 (28)

Switch to inverse

F U2 F' //pseudo F2L -1
L2 U L' U' L2 U // L4C

Skeleton - @ U' F' U' F2 U' L2 * U L U' L2 F U2 F' D' B F2 D' F U2 (19)

Insert at @: F D F' U' F D' F' U (3 moves cancel)
Insert at *: L' D' L U L' D L U' (4 moves cancel)

Can I get some help with a scramble please?

B L' D L' R' U' F D R2 D2 B R B' F D' F' R F' R' F R' D F

Here was my solution:

F U' B' D L' U' F' R U' F B2 D2 F2 // really short F2L-ish // 13
L U2 L' B' R B U B' F' U' F U R U2 R' F R2 U R' U' R U R' U' F' // ridiculously long orientation phase // 25/38
L' U' L U L F' L2 U L U L' U' L F U2 // T-perm. // 15/53
Anyone know how I could shorten that orientation? This was my second beginning I tried and I had 30 minutes to work on it. I don't know full OLL or ZBLL or anything like that...

Alternatively, is there a way I should have seen that this wasn't a beginning worth saving? I'm new to FMC, so I'm very open to suggestions. I know you generally should try to find an insertion and stuff like that, but I just so happened to know the WV case and I already had the pair made so I used that and was left with a T-perm.

Stupid 28... only took 10 minutes and it had 11 move 2x2x3 sooo yeah... pretty sad.

Scramble: F2 D2 L2 B F2 R2 D2 R2 U2 R2 B' D R' U F2 U2 B D2 U F U2
Inverse: U2 F’ U’ D2 B’ U2 F2 U’ R D’ B R2 U2 R2 D2 R2 F2 B’ L2 D2 F2

inverse: U F’ B’ U B L' R2 // almost 2x2x3
SWITCH
R2 L B’ U’ B F U’ premove on normal:

B D L2 D’ // finish 2x2x3
B’ U B2 U2 B’ U // 3rd f2l slot
B' L' B2 L // pair up last f2l pair
B2 L’ B2 R B’ L B R' // WV cancelled with J perm
R2 L B’ U’ B F U’ // fix premove

final (28): B D L2 D’ B’ U B2 U2 B’ U B’ L’ B2 L B2 L’ B2 R B’ L B R L B’ U’ B F U’

just got a 27 (tied pb)... gonna go for pb mo3....

That blockbuilding is rather weird. I would suggest using 2x2x2->2x2x3->F2L-1 (which is an XXXcross). Of course you shouldn't restrict yourself to just this but it's a good way to go.

Also, if you have a T perm with a U2 AUF, I would suggest using that one alg that solves the T perm and the AUF simultaneously, saving you 1 move. Can't recall what it is right now but it's out there.

how come the l3c case i get on the inverse scramble (in NISS) is not related to the commutator case on the total skeleton?

the corners involved are different. why is that?

I am really bad at FMC, but I really want to improve. Can someone help me to get better, because I kinda suck. I did an example solve that was pretty good for me.(It is the weekly comp scramble)

Scramble: D L U2 R2 L U' B2 R B L' D' F' R' D' B2 L D U2 B' F2
2x2x2: Z2 R B' U L U' L U2 L' (8/8)
2X2X3: U' F2 B U' B' U2 B' R B (9/17)
F2L-1: U2 F2 R U' R' U2 F U F' (9/26)
LS: R U' R' U' F' U' F (7/33)
OLL: R U R' U' Lw' L U R U' Rw' (10/43)
PLL: U' F2 U' R' L F2 R L' U' F2 (10/53)
Final Solution:Z2 R B' U L U' L U2 L' U' F2 B U' B' U2 B' R B U2 F2 R U' R' U2 F U F' R U' R' U' F' U' F R U R' U' Lw' L U R U' Rw' U' F2 U' R' L F2 R L' U' F2

Don't do OLL and PLL. Instead try to orient and permute edges and solve the corners using commutators.

Get a skip or do what wonttola said.

Also work on block building.

You know how when you use NISS your blocks are different (and placed differently) in normal and inverse scramble? It's the same thing. Understanding simple premoves (1 or 2 HTM) better will probably make this more obvious.

what do you mean "the blocks are different"?

shouldnt they be the same?

if [SCRAMBLE] + [MOVES] creates a 3x2x2 block, then [MOVES] ' + [SCRAMBLE] ' has to create the same block, right?

just like how the T-perm backwards sets up the T-perm.


is this only the case when you switch back and forth from the Normal to the Inverse scramble multiple times?

24 move solution for weekly competition (not weekly FMC) with ridiculous cancellations

Scramble: D' F2 U F2 L2 D B2 L2 D' L2 U' L D F2 R' B F2 R D R2 D

on normal: R // form a second pair
on inverse: D2 R' B2 D U' // 2x2x2
on normal: L' U L U // 2x2x3
F2 L F2 L2 F // F2L - 1
F L' F' L D' L' D L // up to two twisted corners

skeleton: R L' U L U F2 L F2 L2 F2 L' F' L D' * L' D L U D' B2 R D2
At * I inserted [U, L' D L] which cancels 8 moves

new skeleton: R L' ** U L U' F2 L F2 L2 F2 L' F' L D' U L' D L D' B2 R D2
now at ** I inserted [R, U L U'] which cancels 6 moves

final solution: R2 L' U L U' R' U2 F2 L F2 L2 F2 L' F' L D' U L' D L D' B2 R D2 (24)

14 moves cancelled total, so twisting the two corners with 2 inserted 3-cycles only added 2 moves.
Insertion Finder also got 24 moves with my skeleton.
My previous pb was 29

Wow, your first commutator added 0 moves.

any help? This scramble looks good.

I found this solution:

on inverse: R' B D2 B2 // F2L - 1
on normal: D' B D' B' // F2L

skeleton: U2 R F2 U2 L2 U' R D' B D' B' D2 L B D B' D' L' B2 D2 B' * R
insert at *: [B R B', L']

final solution: U2 R F2 U2 L2 U' R D' B D' B' D2 L B D B' D' L' B2 D2 R B' L' B R' B' L' R (28)

24 move solution for weekly competition (not weekly FMC) with ridiculous cancellations
Were you aware you could go straight to the 3-corners? I may just have more practice but I would see you could change it like this.

Scramble: D' F2 U F2 L2 D B2 L2 D' L2 U' L D F2 R' B F2 R D R2 D

on normal: R // form a second pair
on inverse: D2 R' B2 D U' // 2x2x2
on normal: L' U L U // 2x2x3
F2 L F2 L2 F // F2L - 1
F L' F' L D' [Add U to Change which corner is influenced] L' D L [Fix U with U'] // up to two twisted corners

It just happens that the added U' at the end cancels with the premoves :tu

With my NISS notation (moves in brackets are done on inverse scramble):

(U D' L2) //2x2x2
(U F) //EO
L' U L //Pairs
D R' D' U2 //F2L-1
R2 U' R2 U R' //All but 5 corners

IF finishes in 25: http://mf.qiyuuu.com/cube/if/7ffe176126fc2fc1498e9bf0787bafd4.cube

That 2x2x2 + EO on inverse gives many good continuations, such as:

(U D' L2)
(U F')
(D R2 D' U')
L' U L
R' U

or

(U D' L2)
(U F')
L' U L R2
(U' R U D R2 D' R2 U2 R')
