Found a really easy start on a scramble, anyone mind to finish?

Scramble: L2 D2 B2 L2 D L2 D' L2 D2 F2 U' B' U F R2 B' D' F2 R B' R2, Inverse is on ()

R F U’ F2 (2x2)
(D2 B2 D2 L2) (2x2x3)

EDIT: Whoops, just realised something in here is wrong. I'll try to fix it.

interesting 23 with 2 edge insertions

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

& B F' D R' D2 // 2x2x2
U' F @ R2 // pseudo 2x2x3
U R' F' R U2 R // to L5E

& = [E', B2]
@ = [F' U F, M2]

Final solution: U' D L2 U D' B' F' D R' D2 F R2 L2 B' D' B L2 U R' F' R U2 R (23)

solution is 19 in ATM #### CyanSandwich

Tied my PB. Just a lucky end to the skeleton.

L B2 F2 L U2 B2 R' D2 F2 U2 R B D2 F R' B D R' B2 D' R'
i: R D B2 R D' B' R F' D2 B' R' U2 F2 D2 R B2 U2 L' F2 B2 L'

(F L R2 F' B R2) //2x2x2
(L B' L2) //2x2x3
(D' R' B2 R D') //F2L-1
(R D' R' D) //3C (18)

sk: D' R D R' D R' B2 R D L2 B L' R2 B' ^ F R2 L' F'

^ D' F U2 F' D F U2 F'

solution: D' R D R' D R' B2 R D L2 B L' R2 B' D' F U2 F' D F U2 R2 L' F' (24)

Also landed me a PB mo3 (29.00) and ao5 (29.67)
32, 27, 30, 33, 24

from the past 25 weeks of the weekly FMC:

22, 28, 28, 27, 26, 23, 24, 27, 24, 23, 23, 26, 26, 26, 26, 28, 28, 24, 25, 25, 29, 24, 24, 25, 27

25.52 avg25

and since I haven't posted it yet, here's the 30 from my 26.67 official mean last weekend:
scramble: B2 L2 U2 B2 D B2 U2 R D2 U B2 R' B F' L D2 F' U R

B2 // form pair
L2 B D' B2 // 2x2x2
F2 L2 D' L' D L' F' L // F2L - 1
(D2 B D' B') // insert edge
(D' F' R' B R' B' R2 F) // to L3C

skeleton:
B2 L2 B D' B2 F2 L2 D' L' D L' F' L F' R2 B R B' R F D @ B D B' D2
@ = [D', F U' F']

Final solution: B2 L2 B D' B2 F2 L2 D' L' D L' F' L F' R2 B R B' R F2 U' F' D F U F' B D B' D2 (30)

after trying it again now, I quickly saw that I could have done D2 B D' R D' R' B' after the F2L - 1 for L5C, and IF gives a 29. I'm fairly sure this is what Mark did on this scramble, since he told me he had a 20 to L5C and got a 29.

So I had a bit of a nightmare at Manchester Open 2016. The scramble was excellent but the skeleton I found was only discovered in the last 8 minutes. The A9 commutator at the end cancelled 2 moves leaving me with a 31, which I wrote down incorrectly in the last 30 seconds, getting a DNF. Later in the evening we looked back on solutions together and optimal cancellation was 3 moves which would have resulted in a 29.

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

L' D R2 * U // 2x2x2
D2 B2 D2 R2 // 2x2x3
(R D' B D B') // F2L-1 (And two lucky pairs)
(D B R' B2 D B R F D' F' D') // 3C (24)

* R D' R' U R D R' U' // Insertion cancelling 3 moves.

Final solution: L' D R' D' R' U R D R' D2 B2 D2 R2 D F D F' R' B' D' B2 R B' D' B D' B' D R'

So this block building to 3C was pretty weird, was testing hedges and sledges and making pairs. The solution is actually just a hedge, then making a square, which cancels 4 moves. I must have seen the point up until F2L-1 like 100 times over the hour, it was extremely frustrating.

Got my first 25. Although I've had two 24's and two 26's L2 B2 R2 D2 U B2 D' U2 R2 D2 L B' D' U2 F U L2 F2 R' U2
i: U2 R F2 L2 U' F' U2 D B L' D2 R2 U2 D B2 U' D2 R2 B2 L2

(L' B) //Pseudo 2x2x2
D //Fix
R U' F2 U2 F' //Pseudo 2x2x3
(F) //Fix
(B U B' U' R) //F2L-1
(F R U R' U' F' U2) //3C (20)

sk: D R U' F2 U2 F' U2 F U R U' (*) R' F' R' U B U' B2 F' L

* U' L2 U R' U' L2 U R (Cancels 3)

Solution: D R U' F2 U2 F' U2 F U R U2 L2 U R' U' L2 U F' R' U B U' B2 F' L (25)

Also
27, 31, 32, 33, 29, 37, 29, 26, 28, DNF, 28, 25 = 30.00 (Plenty of chances to roll it though)

You have a lot to work with. Here is just some stuff I threw together that might help you come up with some ideas.

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

PREMOVE F'

then do a R

INVERSE: R2 B R' F2 D B R2 F' U' B U F2 D2 L2 D L2 D' L2 B2 D2 L2

(R') R2 B R' F2 D B R2 F' U' B U F2 D2 L2 D L2 D' L2 B2 D2 L2

F L' B' L B' U2

L' U D' B D U'L'

I'm Pretty sure I hit a dead end here, but a one move psuedo 2x2 is really lucky and something you should be able to work with 90% of the time.

Does anyone wanna try this scramble? It seemed utterly **** to me. I had 27 moves to L5C but DNF'd.
(U D2 B2 L D2 L') // 2x2x2
(D R B2) B // 2x2x3
(B R B' D F D' F') // 2 squares

lel first attempt 23 to 3c with a very very bad solution on inverse:
L B' U2 R' // eo [4/4]
F D' F U' // x-cross [4/8]
D2 B D' B2 D' B // f2l 2 [6/14]
D' F' D F D F' D F D' // ab3c [9/23]

Damn, I went for the same 2x2x2 as you but it was (D' L2 U D' F2 R F2)
I didn't even consider solving the "cross edges" before matching up the pair. I definitely would've seen the 2x2x3, maybe the rest.

I gotta try starting with EO some time. Although I doubt I would have seen the x-cross (or tried to make one). Still something to consider doing.
That's a nice skeleton for a first attempt, but I guess it just had a really lucky ending #### Keroma12

PB: 31
Weekly Competition

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

The first part is a modification of the cross L B' R' F' U'

Cross + 3 F2L edges: L F' D2 F (1) B' R' (2) F' U' (8/8)
Rest of edges: D F L' F' (3) L D2 (6/14)
This leaves 7 corners unsolved.

Solve 2 corners at (1): F' D F U' F' D' F U (cancel 3)
Solve 2 corners at (2): R2 F L' F' R2 F L F' (cancel 2)
Solve 3 corners at (3): F D B' D' F' D B D' (cancel 2)

Solution: L F' D' F U' F' D' F U B' R F L' F' R2 F L F2 U' D F L' D B' D' F' D B D' L D2 (31)

Tried to extend that white cross to an x-cross, but couldn't get the corners to work, so just went with the edges, and it worked out well.
Spent about 45 minutes doing the insertions; optimal would have been 28.
Do people ever really go with 7 corners? If so, do they expect to find the optimal insertions?

I'm new to FMC. Today I began to try use corner-cycle in my solution
THE Scramble: L' B2 L' B2 L' D2 B2 U2 B2 F2 L U L' U' B F' U' L' F D'

And my solution:
NISS
R
NISS
D L' B F R D' R' U2 // 223
NISS
L F L' F' D B' L B // TEC
L' D L B D2 B' // l5c

Howerver, It's diffcult for me to insert. So just got DNF(or 39f without inserting, it's my first time to sub 40 without lucky case).
I can't recognize the corner to cycle when I review the solution, and always make wrong.

And my solution seems to be too long before inserting,What's the better choice?

Hi guys, on this week's FMC competition scramble i found a nice 19 move skeleton but unfotunately I dind't know how to continue, somebody mind cheking out please??
Scramble: (Premove: F2 ) U' R2 B2 D' R2 D2 L2 D' L2 D' F' R' B L' D2 U B2 L2 F U'

Skeleton:L F R' B//Edge orientation
L D' L B2 L' B2 R' B2 R U' R' U' L' U' L// 3 corners and 2 edges

I've been trying to do some NISS, but I realized I don't know what I'm doing..

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

This is what I've done so far.
(F D' L D2 U' L) //2x2
R D // Pseudo F2L-2

At this point I would like to switch back to inverse, but then the 2x2x1 square I just made ends up a D2 away. I'm guessing I have to insert a D2 premove somewhere, but I can't figure out where to put it. Can someone explain to me how I can keep that block when I switch?

R D // Pseudo F2L-2
You made a pseudo block.
If you continue without switching you will need to add a D2 premove.
If you switch back you will see that D2 creates the block.

Premoves on the scramble are moves on the inverse, and vice versa.

ahh so that's where the premove goes. That makes sense now that I think about it. Thanks!

you can also do VLS on inverse: (L' D' L D' F L B' L' B F')

to get to the 3-corner skeleton directly
