[Help Thread] FMC Discussion

I just vaguely remembered that that case could be solved with a 6+8 alg combo (with cancellations), so after trying another 6-mover I found the right solution. The nice thing about LL algs in FMC is that you really don't need to know them well at all to be able to use them in solutions. That reminds me that maybe I should finally finish learning 10htmll, it's really not that much to memorize.

My practice attempt for this weekend.

I figured I'd do a practice attempt on the same scramble since we're going to the same comp this weekend.

2x2x1: U' F'
2x2x2: U R' U2
2x2x3: B L' D
F2L -1: L D' B D B' D' B D
L3C: B L2 B' L B L' B' L *

Insert at *: L' B L F L' B' L F (6 moves cancel)

Solution: U' F' U R' U2 B L' D L D' B D B' D' B D B L2 B' L B F L' B' L F' - 26 moves

nice way to hide an LL skip :P

To be honest, that's the way I solved it. I even stickered my corners before realizing I could cancel a bunch of moves by just putting a comm at the end. I figured I should write it down the way I actually solved it rather than make people think I was good enough to see such a solution.
 
Got the FMC NR, finally a sub 30 official solve. The funny thing is that I am now tied with two other Indians with a 29 move solution.

Done at NCRO '14

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

Solution : On Inverse scramble

B D F U' // 2X2
L U B D2 B' // 2X2X3 + cancellation
D2 R D R' U' // F2L minus 1
B' D' B D B2 D' B D // F2L leaving 3 corners
// (D D' cancelled)
D' Lw B L' B' Lw' D L B' // COLL

Final solution - B L' D' Lw B L B' Lw' B' D B2 D' B' D B U R D' R' D2 B D2 B' U' L' U F' D' B'

My 35 move winning solution from BOW.

[U', L' U2 L] insert at *, I couldn't find any cancellations

IF finds a 4 move cancellation for a 31 move solve :/

D' L' R' U' R B2 F2 U F L F' B' U' B L U [@1] F' L F L' U' L U' L' U' L F
Insert at @1: U' L' U R U' L U R'
Fewest moves: 31. 4 moves cancelled
The final solution: D' L' R' U' R B2 F2 U F L F' B' U' B U R U' L U R' F' L F L' U' L U' L' U' L F

F // CE pair but found nothing great so switch to inverse

F' // premove
B2 L' U F U2 R2 F' D F2 R L2 F L2 F B2 U2 L2 B D2 R2 // inverse scramble

B L // square
R D R' // Roux block
B D2 F2 D' // 2x2x3
L' U L' U2 L // square
L' U2 B L' B' U2 L // add EO
U L' U // F2L

there are a couple of ways for Sune to L3C and 1 cancels a move too, but switching back to normal is better

U' L U' L' U2 B L B' L U' L D F2 D2 B' R D' R' F L' B' // premoves (lol)
R2 D2 B' L2 U2 B2 F' L2 F' L2 R' F2 D' F R2 U2 F' U' L B2 // scramble

L' F L' F' L2 F // leave 3 corners, which is Sune with the original F cancelled and no AUF

leaving this skeleton:

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

L' F (#) L' F' L2 (@) F
U' (%) L U' L' U2 B L B' L U' L

# [F R F', L2] 2

I've tried a scramble from current Weekly Competition, but I had no idea to do AB3C.
On every scrambles, it is very hard to find good AB3C to me... Is there any tips to do AB3C?

Scramble: U F' L B2 U' L F2 B R' U2 B2 R2 F U2 L2 D2 F' U2 B
Inv. Scramble: B' U2 F D2 L2 U2 F' R2 B2 U2 R B' F2 L' U B2 L' F U'


(Normal)
U F' // 1x2x2

(Inverse)
F U' // Premove
R' F R2 // 2x2x2
B' L D2 B L' B D2 B L' B D // F2L-1

Weekly FMC id#24 (ongoing)
Scramble: U2 D B F R' L F' R2 U B F' U' D' L R U B' L' R F2

Solution:
y' z R F' R2 L' U' // 1x2x3 (5/5)
L2 B L F2 //pseudo 2x2x3 (4/9)
R' B R2 //f2l-1 (3/12)
B' R' B' R2 D' R2 D R' D' R D //finish f2l :( (11/23)
z' R2 B' R' B R' F' U' F R U R' U F' //t-perm + 2flip + AUF (13/36)
With cancellations it comes out to 35 moves. Need to get better with insertions before Nats, it was pretty lucky that I got a t-perm + 2-flip at the end that I knew from Classic Pochmann. I found some decent skeletons but going through to find a good insertion with cancellations would put me over an hour for sure.

As an alternative, this new site works nicely: http://www.ocf.berkeley.edu/~dadams/fmc/
Last week only 2 solutions were submitted, it will be nice to have more people competing :)

Yay a new FM competition site. I will try take part sometimes. I never liked mustcube because of the long scrambles.

David - are you going to develop the site further? Perhaps an image of the scrambled cube? Eventually some statistics e.g. averages?

I'm going to be really busy with work/university this summer but I have a little while before it all starts up so I'm planning on pushing out some updates in the next week. Picture of the cube is a pretty high priority and should be up soon. In the mean time there is a link to an alg.cubing.net with the scramble.
 
First FMC solve, need tips!!!

Hello everybody

I just did my first FMC solve:

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

Solution:

F D' L' U' L' // (2x2x2) (5/5)
B2 D2 B' F D F' // (2x2x3) (6/11)
R U' B U R B' R' B R' B' R B // (F2L -1) (12/23)
R' B R2 B' R2 B R' B' // (F2L) (8/31)
D2 L D' R2 D L' D' R2 D' // (OLL) (9/40)
R2 D R' D R D R D R' D' R' D2 R' // (PLL) (13/53)

I know it's very bad but I don't know any commutator or FMC technique (just that Petrus is better than CFOP)
And I just know 4LLL..
Do you have tips for me?

Thanks in advance
