The FMC thread

[Sebastien]

Thanks - it was a lucky scramble. Unfortunately, as usual, I seem to be not very good at lucky scrambles - there are just too many possibilities and I get lost in them. I got a lucky 29 move solve on it due to a PLL skip in 10 minutes, but I couldn't come up with anything better after an hour.

I quickly managed to find a 27 move solution and spent like 2 hours in total on the scramble, found like 5 or 6 different sub30 move solution but none better than 27 :/

Can't wait to see if and how others did better!

I while back I mentioned a possible video FMC 'tutorial'. I finally have a camera (thanks Mollerz) so I intend to film some stuff soon. As it essentially impossible to give a tutorial on FMC, my intention is to do several videos on topics, giving a range of ideas. The overall intention is to stop people from having to answer the same questions over and over again by having a video to link people to. I know there is a fair amount of text dotted all over the internet, so I'll be having a look over that too for ideas. I'd appreciate feedback on the general topics rather than specific tips to include.

1. Basic overview: Includes some important rules, some of the methods that are used, and a few general tips. Kind of like an FAQ.
2. Starting a solve and finding continuations
3. Finishing a solve/skeleton
4. Insertions (corners inc. 4 and 5 corners left, and edges too)
5. Pseudo blocks and using the inverse scramble (including NISS ofc)

A couple of random fun scrambles I tried tonight

Spoiler:

[21:12] <+RobertY> 10.89 OH
[21:12] <+RobertY> B2 U2 F2 L2 D B2 F2 D2 U' R2 L2 F' D' L' D R B R F D2 R
CFOP ish solve, so I'll add rotation in there at the start. Rob only did up to F2L#2 the same during the solve. I found the rest by randomly playing around.
Cross: z D' B
1: F U' F'
2: U' L U' L'
3+4: U' R' U' R U' R' U' R2 U' R'
LL: R U B R B' R' B R B' R' U' R' U'
28 moves

Spoiler:

A very nice scramble at the weekly competition on this forum (2012-20).
I had a crazy solve.
I' will post it next monday...

What's the UWR for most moves cancelled to final solution ratio? Just wondering because I just got a 28 move solution with 12 moves cancelled (12:28 = 42%)

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

U' R2 D' B // EOLine (4/4)
R' F2 R L2 U' L2 U F2 // Left Block (8/12)
U' R' U2 D' R U2 L U' R' U L' D // Right Block + Edges (12/24)

U' R2 D' B R' F2 L2 [.] R U' L2 U F2 U' R' U2 D' R [,] U2 L U' R' U L' D
. = U' L2 U R U' L2 U R'
, = L D2 L' U2 L D2 L' U2
U' R2 D' B R' F2 L2 U' L2 U R U' L2 U R' R U' L2 U F2 U' R' U2 D' R L D2 L' U2 L D2 L' U2 U2 L U' R' U L' D

28 turns (12 cancelled)

I'm not sure what is the UWR exactly, but at least I got 20-move solution with 11-move cancellation.
See my solve in Weekly competition 2010-21. 11:20 = 55%.

[Pyjam]

And me, 18 moves cancelled for 25-move final solution = 72%

NEMO Open 1st place: 28 moves

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

Solution

2x2x2: L F2 B L U L (6)
Extend to triple X-cross: B2 R U2 R B R (6)

Switched to the inverse now using of course premoves: R' B' R' U2 R' B2 L' U' L' B' F2 L'

Pair plus OLL: B' L U' L' U L' (6)
Cancel into J-perm: B2 R' B2 L B' L' B2 R L B' (10)

Full solution:
L F2 B L U L B2 R U2 R B R B L' R' B2 L B L' B2 R B2 L U' L U L' B (28)

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

Solution

2x2x2: L F2 B L U L (6)
Extend to triple X-cross: B2 R U2 R B R (6)

I thought this finish is quite obvious
F2L-1 as above
B L' B' L U B' U' B' U B U' B2 (24)
