you will definitely not like this but...

L' U2 //2x2x2 (2/2)
F R' D //2x2x3 (3/5)
R2 F2 R F' D R2 D' //F2L-1 (7/12)
F R' F' R' //4 corners (4/16)

Solve the rest: (R F R' F')*3 (3 times sexy move)

5 move cancelation.

(Inverse) Solution: L' U2 F R' D R2 F2 R F' D R2 D' F R2 F' R F R' F' R F R' F'

23 moves.

Wow. I definitely see the triple sexy now, but I never would have thought to even try that.

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

B' L D2 L'//2x2x2
D' F' U' F D//2x2x3
switch to inverse
R U' R'//EO
U F U' F2 U'//edges+1 corner

Skeleton: B' L D2 L' D' F' U' [1] F D U F2 U F' U' R U R'

This leaves me with two twisted corners and a 3 cycle. I can insert the 3 cycle [L2, F R' F'] at [1] and cancel 2 moves, which leaves

Skeleton: B' L D2 L' D' F' U' L2 F R' F' L2 F R D U F2 U F' U' R U R'

How would I make an insertion for the two twisted corners? Also, was there a better insertion for the 3-cycle?

 

[Bubtore]

I just want to share my solution (of the 2nd scramble of the german forum competition) because of that amazing insertion !

What can I improve? I know there is a loooooot to improve, but how?

I didn't really know what to do after F2L-1. I couldn't find a good way to orient edges.

Sorry, I'm really new to FMC, but what does "switch to inverse" and "on inverse" mean?

You might be able to find better blocks to build by using the inverse scramble instead of the normal. Look up "NISS" (Normal Inverse Scramble Switch) on the wiki.

I'd found that one but too late. I've never done edge insertions before either, so I was afraid to try it during a "serious" attempt.

 

[cubingallday]

I really new to FMC, so with I tried this scramble for my first FMC try: U2 F2 D' L2 U L2 R2 U L2 B2 L U' F' R' U' B L B F R
I got a 45 move solution, which I think is pretty good for my first FMC try.

D F R' U' D B' // 2x2 block (6|45)
L' F' U F2 L2 // 2x3 block (11|45)
D' F' L F L' U2 D // F2L #3 (18|45)

F' L F L' F' L' R U L U' R D2 R' U' R D2 R' U' R' // LL (45|45)

Any Tips on this solution?

Did one per day except monday. I've already sent the 38 moves one, and I wrote the others as a comment of the solve.
Basically I build 2x2, 2x2x3, F2L-1, edges, 1 or 2 commutators, then insertion, all using NISS.

[obelisk477]

I have a question regarding 'splits' for FMC (if you could call it that). How much time do you guys spend looking for a decent 2x2x3, F2L-1, looking for insertions, writing down inverse scrambles, checking solutions, etc, etc?

With your (very good) start:

F B' R L' D' F2 B' D2 F //Your XXXcross
U B' U' B //All but 4 corners

Run into Insertion finder:

F B' R L' [@1] D' F2 B' D2 F U B' U' B
Insert at @1: F2 D' B2 D F2 D' B2 D
After the 1st insertion: F B' R L' F2 D' B2 D F2 D' B F2 D2 F U [@2] B' U' B
Insert at @2: U' L' U R U' L U R'
Fewest moves: 24. 5 moves cancelled

I don't use fixed time splits. I don't know if it's a good idea, because you shouldn't have fixed steps in you solving method/style/approach.
I just try to have some solution written down 5 to 10 minutes before the end.

Fun and very easy scramble from this forum: B2 U R2 F2 R2 D' B2 F2 U R2 D2 F D2 F2 U2 R' B' L' B D2 F

Spoiler

Some cool stuff: ["(...)" means apply on inverse] F' R (R2) 2x2x2 - then L B2 D' L D' for F2L-1 in 8 moves
or: same 2x2x2, then continue on inverse: (D2 B2) for a 2x2x3 in 5 moves, continuing with (L B' L' B) for an F2L-1 in 9 moves, and another 8 moves (find those yourself ) for L3C in 17 total. (final solution was 23)
