I wanna get good at FMC so I can be cool like @Cale S :D. I currently suck, but I got a pretty lucky solve with no NISS. Tied PB

If a 2x2x2 has no pairs, try inserting a move somewhere, here, you can do
(<F/F2/F'> R D F' R' B) (none are particularly good)
(R <F/F2/F'> D F' R' B) (F makes a pair)
(R D <U/U2/U'> F' R' B) (none are great)
(R D F' <U/U2/U'> R' B) (none are great)
(R D F' R' <U/U2/U'> B) (one pair with U2)

This 2x2x2 here wasn't particularly good, but when doing this, we saw that (F) made a pair when done before the 2x2x2.
Now, this seems a bit more obvious:
(F) //pair
(R D) //square
(U F') // another square
5 moves to 2 squares is decent, and it leads to 3 9 move 2x2x3s too :)
(F R D U F')
(R2 F2 R B)
and
(F R D U F')
(R F2 R2 B) //this one has two pairs
and
(F R D U F')
L' B' R' (R2) // one pair

Another thing to try is just looking for ways to make 1 move pairs from the original scramble, which found us the 2x2x3s. This doesn't lead to much on this scramble though...

Also, there's a 4 move 2x2x2 if you play around
(D' B U R)
Then some EO continuations are decent
(F2 L' F2 L' F') //EO+square
or
(L2 F2 L F')//EO
(U L F2 U2) U //2x2x3
L2 U L' U' D' L D //20 to 3c3e

Skeleton: U L2 U L' @ D' U' L D U2 ^ F2 L' U' F L' F2 L2 R' U' B' D
@ L' D' L2 D L2 D' L' D (8-3)
^ D' L U2 L' D L U2 L' (8-2)
=31 moves

Just a quickish solution, turned out alright. Hope this helps :)

oh wow, didn't see that 2x2
i tried that start but without the F2 before EO
(D' B U R)
(L' F2 L' F')
(F2 L2 U F2) // blocks
F2 U L U' L2 U L2 U' // L4C

skeleton: F2 U L U' L2 U L2 U' F2 U' L2 F' L F2 L R' U' B' D
IF says 29 is optimal

thanks!
 
After playing around a lot more with my partial solution I got this:

Scramble: F' U' L' D2 B2 L' U2 D L' R2 U' R' L' U L2 B2 R' L F2 R B2 F U' R
2x2x2: F2 U L' U2 B' [5/5]
F2L-1: L F' U2 F' U F' L2 * [7/12]
Orient F-layer edges: (U F' U') [3/15]
AB3C: (F2 R' F R F' R' F2 R F') [9/24]
Insert at * (from IF): U F D F' U' F D' F' [6/30]
Solution: F2 U L' U2 B' L F' U2 F' U F' L2 U F D F' U' F D' R' F2 R F R' F' R F2 U F U' (30)
...which is ultimately not any better than my 1 hour solution :(

Thanks BQ - this is awesome! I think I get too tunnel-visioned into forcing a skeleton for inserts that I can miss these sort of solutions. On the other hand I don't know 1-look OLL so I'd probably never have spotted this one anyway.

But in that spirit, I turned to working on Daniel Lin's scramble to try get a similar PLL skip. Spent way too long on it and not sure how useful this will be for him, but I had fun... :p

Starting with Daniel Lin's 2x2x2 I eventually found the following:

Scramble: R' D2 F2 D2 B2 D' R2 D2 F2 U' F2 L2 B' U' B' D' F' L2 R U2 B2
2x2x2 (from Daniel Lin): (R D F' R' B) [5/5]

EO: F U F' [2/13]
F2L-1: U L' U' L2 U L' [6/19]
F2L: U2 L' U2 L [4/23]
OCLL (Antisune): L' U' L U' L' U2 L [4/27]
PLL (Skip): U' [1/28]
Solution: F2 L' F U2 F2 U F' U L' U' L2 U L' U2 L' U L U' L' U2 L U' F2 B' R F D' R' (28)

I'll try and keep an eye out for these opportunities in my future solves.
 
I just found a really easy 18-move solution on an official scramble :-)
The scramble is from ZiboOpen2017
R' U' F D L2 U2 R2 F2 D' R2 F D2 R' B2 L B F R' F' L2 R' U R' U' F

2x2x2: (B' L' U' B2 U' R2)
F2L-1: U F
finish: (F L2 F U' L U2 B' U' B L2)

Solution: U F L2 B' U B U2 L' U F' L2 F' R2 U B2 U L B (18)
 
If someone with little experience wanted to get 30-40 movecount, where would I start? I’m interested in learning some FMC.

In fact, I don't know 1-look OLL too. I just tried it.
 
Got three 28-move solves at SG Cube Championship 2018! (… but two of them were for the same scramble lol)

Really happy about getting a sub-30 official average (by the smallest possible margin, with a 29.67) after a drought of sub-30 singles at home.

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

L' U F D2 B2 // blocks (5/5)
(L') // moar blox (1/6)
R2 U2 // arrange blocks (2/8)
F' D F2 D' F' // set up edges (5/13)
U L2 U2 // ab5c (3/16)

Skeleton: L' # U F D2 B2 @ R2 U2 F' D F2 D' F' U L2 U2 L
@ = [B2, L' F L] // 2 cancel
# = [L F2 L', B2] // 2 cancel (16-4/28)

Missed optimal insertions (26 moves) because I'm dumb.

Another 28-mover (the one I actually wrote down, because ZBLL style points):
(L' U B) // two squares + pair (3/3)
L' U B' U2 L2 // eoxxcross (5/8)
F D' F' D F D' F2 D' F // F2L (9/17)
F' D' R' D2 R D F L D L' D' L D' L' // optimal ZBLL (14-3/28)
scramble:
R' U' F D2 B2 D2 B2 F' U2 R2 D2 L2 B L' U2 R2 U' R' F L D2 L2 F' R' U' F
solution:
L2 U R F D' F D U2 R U'
R' U' F' U F U' B U' B' U
F R B' U B2 R2 U' L' U R2
U' L U'

(U2 B2 U' B) // pseudo222 + two pairs (4/4)
L2 U R F D' F D // pseudo223 (7/11)
(R' F' U' B U B') // xxxcross (6/17)
(U F' U' F U R U R' U2) // ZBLS; ab3c (9/26)

Skeleton: L2 U R F D' F D U2 R U' R' U' F' U F U' B U' B' U F R B' U B2 @ U2
@ = [R2, U' L' U] // 1 cancel (8-1/33)

26-move ab3c isn't that good, but I was kinda desperate. (I think? I actually don't remember much of what went on at the comp because I've been so sleep deprived lately.)

Backup (36 moves, but ZBLL style points again!):
F' (B L2 B2) R' // xcross (5/5)
F L F' L2 U L U' // second slot (7/12)
B' U B U2 F' L' F U // eo + third slot (8/20)
L' F L F' // last slot (4/24)
U L U' L F2 D F2 D' L' D' L D // optimal ZBLL (12/36)
scramble:
R' U' F L2 R2 D2 R2 U' B2 R2 D L2 D' U L D' F' D2 U R' U L' F2 R' U' F
solution:
D L2 D F2 L F' L' F2 L D F D' F2 U' F D2 F' U F D' F D2 F D' F' R2 B2 F2

I immediately saw the three-move 222 block on inverse after doing the scramble, but my first solution (29) started with the normal scramble anyway.

First solution (29):
L B2 R' B' R' @ B // pseudo223 (6/6)
(L2) // align (1/7)
(F2 U L R' F' L' R) // eo + F2L-1 (7/14)
(F U F' U2 F U F' U' F U2) // F2L; ab3c (10/24)
@ = [R', B L' B'] // 3 cancel (8-3/29)

Second solution (28):
(F2 B2 R2) // 222 (3/3)
(F D F' D) // pseudo223 + three pairs (4/7)
D L2 D F' L // eo + F2L-1 (5/12)
L' F' L F' L' F2 L // tripod (7-3/16)
D F D' F' D F D' // edges; ab3c (7-1/22)

Skeleton: D L2 D F2 L F' L' F2 L D F D' F' @ D F D2 F D' F' R2 B2 F2
@ = [F' U' F, D2] // 2 cancel (8-2/28)

Also found an OCLL skip into J perm based on the above start, but it's 30 moves and I found it after the 29-move solution, so it's useless.
(F2 B2 R2 F D F' D) D L2 D F' L // above (12/12)
F' D F2 D' F2 D F D' // F2L (8/20)
R2 D' F' D R2 U' B U' B' U2 // J perm (10/30)

For some reason I didn't think to check (L2 R2 B2) as a start even though I had a lot of time left.

27.33 FMC NR mean solutions at Singapore Cube Championship 2018, tied with Feliks and Mats :)

1) 28 moves, R' U' F L2 F2 L2 F U2 F D2 L2 U2 F L2 D F D2 F' L' B2 F D B2 R' U' F

L' U F//square (3/3)
(L' F2 U' R2)//2x2x3 with unintended EO (4/7)
(D2 B D2 B2 D)//3C3E (5/12)

I was low on time, so this was the best I could do:

L' U F D' ** B2 * D2 B' D2 R2 U F2 L
*=D2 B2 D2 B' D2 B' D2 B2
**=B2 R F' R' B2 R F R'//not even optimal, i ran out of time :(

Final: L' U F D' B2 R F' R' B2 R F R' B2 D2 B2 D2 B' D2 B' D2 B2 D2 B' D2 R2 U F2 L (28)

IF says optimal for the 3C3E was 23, but with a 6 mover nested inside a corner comm that cancelled 0

2) 27 moves, R' U' F D2 B2 D2 B2 F' U2 R2 D2 L2 B L' U2 R2 U' R' F L D2 L2 F' R' U' F

D' R D F'//EO (4/4)
L2 U R F2//2x2x2 (4/8)
(U2 B2 U2 B2) B2//2x2x3 (5/13)
(R2 U R2)//square(3/16)
(U R' U)//pseudo F2L (3/19)
(R' U' R' U R' U' R2 U2)//sune, cancels into the pseudo fix (8/27)

Final: D' R D F' L2 U R F2 B2 U2 R2 U R U' R U R U' R U' R2 U' R2 B2 U2 B2 U2 (27)

Pretty happy with this, first time i used an EO start in comp :) lucky endings are not a crime.

3) R' U' F L2 R2 D2 R2 U' B2 R2 D L2 D' U L D' F' D2 U R' U L' F2 R' U' F

(F2)//square (1/1)
D2 L D' R2 B2//2x2x3 (5/6)
(B' U' B U2)//F2L-1 (4/10)
F' L F' D F D' F//F2L (7/17)
L U B L B' L' B L B' L' U'//LL (11-1/28-1)

Final: D2 L D' R2 B2 F' L F' D F D' F L U B L B' L' B L B' L' U B' U B F2 (27)

once again, lucky endings are not a crime :)

I did find this interesting skeleton in the remaining time but didnt think it was worth it:

(F2)//square (1/1)
D2 L D' R2 B2//2x2x3 (5/6)
F U F' L2 U2//2 twisted corners+4E (5/11)
I shall also post Firstian Fushada's 24 move solution on this scramble here:
(F2 B2 R2)//2x2x2 (3/3)
(F2 D' F L' D2 L')//2x2x3+make pair (6/9)
(F2 D2 F')//F2L-1 (3/12)
(D' L D' L')//3C (4/16)
(R' B R F' R' B' R F)//Fusheen doesnt know insertions, but this was the optimal insertion anyway (8/24)

40 total. But I used Cube explore to get the twisted corner case. What would you guys do after F2l-1? What algs should a FMCer want to learn? If any?
