and since I haven't posted it yet, here's the 30 from my 26.67 official mean last weekend:

Spoiler

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.

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

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

Spoiler: Solution

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:

Spoiler

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?

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.
