PB from last week:

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

Solve:
B2 D' B' F D F R' F2 D2 F pseudo 2x2x3 (10/10)
X2 R2 Y R U R' X Y2 F2 U' R' L F2 R L' U2 F U F U F' U' F2 everything else (19/29)
B' correct pseudoness

How I found it:
I found two good 2x2x3s: B2 D' B' D' F R' D2 R' U' and (premove: U') B2 D' B' F D F R' F2 D2 F
But I couldnt find a good continuation so I used the second 2x2x3
After that I found out that if continue R2 X2 Y R U R' U2 F' U F U F U' F' you get an OLL skip and PLL is Uperm
But I don't know insertions so I had to use F2 U' R' L F2 U R L' U' F2
But luckily I was able to shave 4 moves off by doing it before I put the last 2 F2L pairs in place
 
My solution for the weekly (the week that has just ended)

Scramble: L' U' B' D F' U R' B D L' B2 D R' L D2 U' L U2 B2 R
Corners First :)

B' R U L' U D2 B //First layer corners -1 move and 6 edges (7/7)
L' B' L B D L' //All corners (6/13)
F D' F2 L D U' F' //3 more edges (7/20)
R2 U F2 D' U L //Finish (6/26)

First time submitting a corners first solution :)
 
Here is my 30.67 Mean from FMC USA 2014.

I found this 19 to L5C in literally 2min, basically the first thing I did.

Scramble - F' R L2 F B2 R F U2 B U' D2 B2 U2 D' R2 D F2 R2 B2
Inverse - B2 R2 F2 D' R2 D U2 B2 D2 U B' U2 F' R' B2 F' L2 R' F

All on normal
R' L B' L' R U2 // 2x2x2 (6/6)
R2 B R2 B // 2x2x3 (4/10)
R2 D' R D F D F2 R2 F // L5C (9/19)

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

[123] * = (B R B' L B R' B' L') cancels 3
[451] # = (L F2 L' B' L F2 L' B) cancels 2

Solution - R' B R B' L B R' B2 F2 L' B' L F2 L' B R U2 R2 B R2 B R2 D' R D F D F2 R2 F (30)

IF says 29 is optimal, I didn't save enough time to find insertions toward the end where optimal is.

R2 B2 R2 B D2 // F2L-1 (5/11)
switch
i: R D' R2 D R B R' B' R2 B R B' R // L3E (13/24)

Skeleton - R2 L B' (U2 F R2 D2 L2 B D2 R2) L' R2 U2 R2 B2 R2 B D2 R' B R' B' R2 B R B' R' D' R2 D R' (8-2/30)

IF says its optimal <3

First insertion - D L F B2 U' F' (F' R F L' F' R' F L) L' F' L D' L2 D' L D' L' D L' D F' // cancels 5

Second insertion - (F D' B2 D F' D' B2 D) D L F B2 U' F2 R F L' F' R' L D' L2 D' L D' L' D L' D F' // cancels 1

Solution - F D' B2 D F' D' B2 D2 L F B2 U' F2 R F L' F' R' L D' L2 D' L D' L' D L' D F' (29)

IF says 27. I was running out of time during the second insertion even though I was almost at the end and I missed the 3move cancellation :'(

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

This scramble can go to hell.
I basically just tried decent 2x2x2s and 2x2x3s until a good continuation came up :p

Start on Normal
R2 L' D2 L U' R U2 // 2x2x2 (7/7)
L2 F' D F2 // 2x2x3 (4/11)
switch
L' F' D2 F // F2L-1 (4/15)
L2 F L' F' // block+pair (4/19)
L U L2 D' L' D L2 U' // L3C (8/27) basically a block comm to preserve stuff

Skeleton
R2 L' D2 L U' R U2 L2 F' D F2 U L2 D' ^ L D L2 U' L' F L F' L2 F' D2 F L

^ = D F' D' B2 D F D' B2 // cancels 2

Solution - R2 L' D2 L U' R U2 L2 F' D F2 U L2 F' D' B2 D F D' B2 L D L2 U' L' F L F' L2 F' D2 F L (33)

IF says optimal :p
http://if.qiyuuu.com/cube/if/a704e177c30e20bafaf9d8122f8ac669.cube

Found this skeleton very late and didn't have any other options

Was hoping for a sub-30 mean and optimal insertions would have gotten me that :/
Not too disappointed with it though.
 
Copied this over from the example solve thread because it's just too lol

FMC USA 2014
Scrambles:
1. F' R L2 F B2 R F U2 B U' D2 B2 U2 D' R2 D F2 R2 B2
2. L F2 L' D2 L2 B2 U2 L' B' F' R' F' D2 F2 L2 D R F U'
3. B2 U R2 D U L2 D2 U' L2 B U2 R' F2 D2 L' F R' D' L' U'

I got 2 DNFs but it was my first ever timed FMC (home or comp), so at least I have an official PB (single ofc, not mo3).
I would like you to try see where you could put commutators in the FIRST AND LAST solves (use different commutators than mine for the last), instead of my OLL PLL endings.

Solution to 1 (54):
Pre-Move D
R' L B' R L' U2 // 2x2x2 6/6
R2 B R2 B //3x3x3 4/10
R F D F' D2 // Pseudo F2L-1 5/15
R' D' R D R2 D B' D' B R' // LP + Edges 10/25
D R2 D2 R' D2 R' D2 R2 D // OLL 9/34
X' U F' R U' R' U' R U R' F' R U R' U' R' F R' F' U2 // PLL 19// 53
X D// Undo Pre-Move

Scramble 2, I found two separate 12 move solutions to the SAME 3x3x2 (47):
D' L' U2 B' R' U // 2x2x2 6/6
D R' B D B' R // 2x2x3 6/12
D L' F2 L F2 L' F2 L // F2L-1 8/20
F D F' D2 F D F' Z2 // LP+EOLL 7/27
L' U R U' L U R' // OLL 7/34
R' U2 R U2 R' F R U R' U' R' U' R' F' R2 U2 // PLL 14/48

Scramble 3, which was the worst for us at Seattle (51):
D' F2 D R' F & D2 L' D' L U // 2x2x3 10/10
D L' D' L D // Add Square 5/15
R U' R' F' U F U' // LP+Edges 10/25
Y R' D' R D R' D' R D U2 D' R' D R D' R' D R U2 // OLL

Insert at &: [D2, B U' B']

Hope I wrote it down correctly, sorry if I did not.

Correction: R B'

Insert at *: D' B U B' D B U' B'

which resulted in 27 moves. Not difficult, why I couldn't find this in that time...
I should have found at least the first one in 1-hour.

Superflip scramble: U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2

I found a 22move solution :)
L' B F' L R' F' U D F2 R' L U2 L' B2 U D' R2 F' U D L2 D2
Explanation:
L' B F' L R' F' placed 6 oriented edges to U and D face,
U D F2 @ B2 edges swap,
R' B2 U D' R2 F' U D L2 D2 all but 3 edges,
insert at @: M' B2 M B2
 
My new PB (18 HTM!) from the example solve game:

Scramble: B L2 D2 F R2 B2 R2 F U' L D B' U L' D L' B F U2 F2 U2
Solution: B2 U B U2 B' U2 B2 U' B2 U' L' R B' L D' L2 D U2 (18)

2x2x3 + EO on inverse: U2 D' L2 D L' B R' L
Switch to normal, some stuff that turned out to be reduction to <B2, U>: B2 U B U2 B'
Finish: U2 B2 U' B2 U'

Can someone check if this is optimal? It would be super cool :)

I started FMC a few weeks ago and have already done 6 attempts (36,36,36,38,30,31) but I want to start taking it more seriously.
Where can I learn insertions?
Click to expand...

You could learn all the pure 8 move commutators. Those are really all the corner cycles you need. There are many good videos on YouTube for that. Many of those commutators might be OLLs you use. Furthermore, you probably already know the A perm and those are good for insertions too.
 
This is my PB so far, although it's actually my first REAL FMC solve that I used an hour, actually wrote the solution and backtraced.
Scramble: U' F' B' L' R2 B' F D B2 L R B2 D L U F' B' U2 F' D2
*Solve*
Weird random block thing: B U F2 R2 F L U2 B (8/39)
F2L + Forced OLL skip: R U L F2 L' U2 R U' R2 U2 R' B U2 B' U B' R B (26/39)
PLL: R u' R U' R U R' u' R2 B U' B' U2 (39/39).
*39 moves total*
It was a little rough at first (Ok... Very), but the set up was good for that OLL skip. And the scramble wasn'y the best so it was good. It was cutting it close though, about 5 minutes left to the hour after I wrote everything down. anyway, do any of you see anything you experts would change? (I'm not color neutral, so I should probably change that somehow)

I'm no expert (only 7 attempts so far)but not being color neutral is a huge mistake.
You should never limit yourself in FMC.
It's not like in speed cubing where if you have recognition problems you lose a few seconds.
In FMC time doesn't matter.


I also tied my PB yesterday.
Scramble: the 47th scramble on David Adams weekly competition(the scramble that NewCuber000 used).

B U F' L' F' 1x2x3 (5/5)
D2 L' F D R' D' L' 2x2x3 (7/12)
U R2 B' R' B R F2L (6/18)
R' F R' F' U' R' U2 F' U' F U' R U R PLL (14/32)
R and R' obviously cancel out so
Final solution: B U F' L' F' D2 L' F D R' D' L' U R2 B' R' B F R' F' U' R' U2 F' U' F U' R U R (30)

It's also part of my mean of 3 PB 30.33 (30,31,30)
 
Interesting scramble taken from this tweet: U F2 U' L2 D' R2 U B2 L2 D' F' D' F' L2 B L B2 R2 D U
I mainly investigated the normal scramble with premove L' .

[1] Pre-scramble: L'
2x2x2 block: D' B L2

2x2x2 block: D' B L2
2x2x3 block: U' B D
Pseudo F2L minus 1 slot: L' R' B' R B2 L
Finish F2L: U B' R
c/e pair: R' B' R
All but 3 corners: B L B2 R' B2 R B2 L'
Corner 3-cycle: L U' L' D L U L' D'
Correction: L'
(30 moves)

[3] Pre-scramble: L'
2x2x2 block: D' R B L2 *
Pseudo 2x2x3 block: B D2 B' D2
Pseudo tripod: U R2 U' +
All but 4 corners: B R' B' R B' D B2
Correction: L'

Insert at *: U' B D2 B' U B D2 B'
Insert at +: D B U B' D' B U' B'
(26 moves)

[4] Pre-scramble: D B' L'
2x2x2 block: D' R B L2
Finish F2L: B D2 B' D U R2 U' D
All but 4 corners: D' B' D2 L' D' L2 B' L'
Correction: D B' L'

IF says the optimal insertions give 27 move.

[5] Pre-scramble: L'
2x2x2 block: D' B L2
2x2x3 block: R U R U'
All but 4 corners: D' B' D' B2 D B2 D2 B D2
Correction: L'

IF says the optimal insertions give 28 move.

[6] Pre-scramble: L'
2x2x2 block: D' B L2
2x2x3 block: R U R U'
All but 3 corners: B' D' B' D2 B2 * D' B' D B2 D2 B2 D'
Correction: L'

Insert at *: B U B' D' B U' B' D

Solution: D' B L2 R U R U' B' D' B' D2 B' U B' D' B U' B2 D B2 D2 B2 D' L' (24 moves) Finally!
