My mo3 (33 moves) at PLS Marina 2014:

Spoiler

1st scramble: R' U2 L2 B' L D' F' U2 B' U F U2 D F2 U2 B2 R2 D F2 D

R' F U' F' // green cross
D' B2 D // 1st slot
B U B U' // 2nd slot
then i couldn't find anything on green face but i see easy block on orange face
D B2 D' R B2 // F2L - 1
R2 B' R2 B R2 U R2 U' R' B U' B' U R' // forced LL skip (what a funny feeling when CE shows that your moves are optimal)

solution: R' F U' F' D' B2 D B U B U' D B2 D' R B2 R2 B' R2 B R2 U R2 U' R' B U' B' U R' (30)

2nd scramble: L' D' B L' F2 L' B D L' F2 B2 L2 U' B2 D' L2 U F2

F2 R2 F2 // 2x2x2
switch to inverse
D L2 B D2 B // 2x2x3
L D' L' D L2 D' L' // F2L - 1
D L' D L B D B' D' L' D2 L // OLL
L' D L' D' L' D' L' D L D L2 D2 // PLL

solution: F2 R2 F2 D2 L2 D' L' D' L D L D L D L D B D' B' L' D' L D' L D L2 D' L D L' B' D2 B' L2 D' (35)
i'm really dissapointed this solution because i found 29 moves but i couldn't do it again


3rd scramble: U F D' R B R2 L' U' R' L' U B' U2 F2 R2 F2 L2 F' R2

L D B' D L' B' // 2x2x2
switch to inverse
U2 R F R' // 2x2x3
switch to normal
F U2 F U' F2 * U F' U2 F U // F2L
D R F R' F' D' F2 // all but 3C

* L D L' U2 L D' L' U2

solution: L D B' D L' B' F U2 F U' F2 L D L' U2 L D' L' U' F' U2 F U D R F R' F' D' F2 R F' R' U2 (34)

Found in less than a minute, written out in less than 5

Okay so I am doing an official-style FMC mo3, and this was my first solve. So normally, I go about finding a good 2x2x3, then try to blockbuild to L3/4C, or possibly to a short LL case. This time, it was quite different.

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

So this was the 10 move 2x2x3 that I found on the inverse scramble in ~20 minutes.
D F B2 L' F' D2 F R' D R // 2x2x3 (10)
So after this, I tried building a pseudo F2L (see if you can find it, I built a 1x2x2 on yellow then added the pair) and that didn't work out too well. I couldn't do any 1LLL stuff, so I was trying to do short stuff, and I remember getting an awkward OLL that I did CPEOLL and antisune, but I couldn't find it again.

So, I finally just convinced myself in the final 4 minutes that I had to write some sort of solution down, so I did an x2 and started doing CFOP. Then this happened.

x2 R U R' F2 // finish XXcross
U' F U F2 L F L' // odd way to pair up these pieces, but it was the first thing I saw, and it looked efficient, so I did it.
F U' F' // accidental 2x2x1 in LL and insert pair
U2 R U R' // make split pair while preserving square

Now here is the crazy part. Keep in mind I had 3 minutes left, and this was my first time trying the scramble in this fashion.

U F' U' F U' // insert pair and LL SKIP!!!!

32 moves, because the last move of the 2x2x3 cancels into the first move of the CFOP finish. In the next two minutes, I wrote down what I did, and then inverted the solution. The clock was a minute past the time I started at, but I didn't know the seconds, so I'm just going to call it an hour. I can't believe this happened, the second unforced LL skip I've ever had.

I will post 2 more attempts either here or later in the thread as I do them, probably over the next few days.

Also, second 32 move solution, (my current best) and the other one was with a ~10 move 2x2x3 and LL skip as well!

Has anyone ever tried doing an FMC-like attempt where you are only given the scramble? No cubes allowed, no picture will be given.

No.

Actually, I think you could do that fairly easily using BLD methods and by tracking the pieces.

You'd start off by writing out the inverse scramble. Then you'd imagine the cube in your head and the do the inverse scramble, tracking the sticker of your BLD buffer.

The place that it goes I your first target.

To figure out your next target, do the same but track the sticker of you last target piece. And so on. Solve using BLD method.

It'll be hard to get it within the move limit though.

Well then, we should use the time taken to write down a valid solution as your 'score'.

Isn't this the BLD FMC that Mike Hughey talked about on Cubecast?

Yeah I did it back when I did almost everything on the weekly comp bld. I think it was 2010 sometime. I guess Mike has done it too (maybe that same week)
I read through the scramble ~20 times, tracing one piece in my head each time. I chose the piece that belonged in the spot where the previous piece ended up so that I would get my bld cycles forming straight away. Then I wrote down a bld solution.

 

[scottishcuber]

Sounds like fun.

 

[Tim Major]

No.

Yes, I think at least two people have, in fact I think they memorized the scramble without touching anything, then put on a blindfold and wrote their solution

 

[CyanSandwich]

Got this crazy scramble from qqtimer with blocks everywhere: F' R2 U2 L D' R F2 L U2 L2 F U2 B L2 D2 L2 B2 L2 B2

I'm a noob so I didn't know what to do with it. I got a 14 move F2l-1 and got stuck.

x' U F' L' R' F' R //2x2x2
y2 U2 R2 U R' F' U' R2 F' //F2l-1

Maybe someone can get something decent with the scramble? I wouldn't mind seeing a nice finish to my start either.

Yes, I did it that week too. Back then, there wasn't the 80 move limit.

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

B F' L U2 R2 U' L . U2 // 2x2x3 (8/19)

insert at . F B' L' B F' D // 5 cycle, cancels 2 moves (6-2/19)

challenge: find where is the lie in the solution. (it is not a prepared scramble and i didn't use any kind of solver software and the movecount should be fine too, don't worry ;D)

Wow, 16 moves in ATM

 

[TDM]

Wow, 17 moves in ATM, but the only thing I could find is that the 5 cycle doesn't cancel anything?

D U2 D' = U2

B F’ z U,
R2 D2 l’ B (last 4 of the scramble: B’ L D2 R2),
I write down without rotation: B F' L U2 R2 U' L (which will be pretty good start )

What's the lie? I don't get it at all.

i am new to fmc and am trying to learn before a comp. Do any of you have beginners tips?
