    So you are permitted to test your solution or move count by manipulating one of the 3 self-supplied cubes.

    Interesting. Thanks!

    Here
    @Neuro I'm definitely not great at FMC. But you could get an Ab3c in 24 moves by doing B2 U B2 U' B' U' B U2 B' U2 B U' B' U2
     
  3. Good luck getting better at FMC then.

    Just do the 15 moves to L5C, that's a pretty good skeleton and optimal insertions should give around a 26

    EDIT: Just checked Insertion Finder and optimal for your skeleton is 23, insertions cancel 5 and 3

    Just dropped my PB from 28 to 22 with this:

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

    U L2 F2 D2 // 2x2x2
    B2 U' F * U' F' U // pseudo F2L-1 (premove L2)
    B2 L B2 L' B' // AB5C
    L2 // correct premove

    At * - B2 U' F' ** U B2 U' F U (cancels 8 :eek:)

    At ** - F' D F U' F' D' F U (cancels 2)

    AB5C in 16 moves, then some ridiculous insertions

    Just got a pretty cool solution with some reverse NISS and lucky insertions.

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

    B' U2 B L2 F // pseudo 2x2x2
    B L2 // pseudo 2x2x3 - 1 edge
    (F' U' L2 U) // 2x2x3
    (D2) // 1x2x2 block
    (B2 R D' R' B' D2) // AB3E and twisted 3C

    Skeleton (18 to 3E and twisted 3C): B' U2 B L2 F B L2 D2 B * R D R' B2 D2 U' L2 U F
    * = B R' B' R (cancels 2)

    New skeleton (20 to 4C): B' U2 B L2 F @ B L2 D2 B2 R' B' $ R2 D R' B2 D2 U' L2 U F
    @ = R2 B L2 B' R2 B L2 B' (cancels 4)
    $ = D L D' R2 D L' D' R2 (cancels 4 again!)

    Solution (28): B' U2 B L2 F R2 B L2 B' R2 B D2 B2 R' B' D L D' R2 D L' R' B2 D2 U' L2 U F

    Nice solve! I'm probably being dense, but isn't this just normal NISS rather than reverse NISS...?

    Thanks! And yeah, there's regular NISS in the first skeleton, but the B R' B' R insertion is reverse NISS.

    I got another really nice solution with reverse NISS! It's such a cool concept; I used it in 3 of my last 5 solves since I found out about it. :)

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

    L' B' // 1x2x2
    (L D2) // 2x2x2
    (R2 U2 R U R2) // 2x2x3
    (L F' L') // pseudo F2L-1
    F U' // AB4E5C

    Skeleton (14 to 4E5C): L' B' F * U' L F L' R2 U' R' U2 R2 D2 L'
    * = F U2 F' // solve an edge
    L U F U' F' L' U // solve L3E + 1 corner
    (cancels 7)

    New skeleton (17 to 4C): L' B' F2 U2 F' L U F $ U' L' R2 U' R' U2 @ R2 D2 L'
    $ = F' D F U' F' D' F U (cancels 4)
    @ = U L U' R' U L' U' R (cancels 2)

    Solution (27): L' B' F2 U2 F' L U D F U' F' D' F L' R2 U' R' U' L U' R' U L' U' R' D2 L'

    Did you try to insert a sune or anti-sune or fat-sune?

    I didn't try that in this one, I just went with a sledge to solve L3E. That's really smart though, especially considering the twisted 3C.

    The best I could find was B2 L B L' B L B2 L' at the same spot which leads to 3E in 25 moves, with a 32 move optimal solution. There are probably better places to insert it though, so definitely something I'll keep in mind for future attempts. Thanks for the suggestion! :)

    In the same spot, you can insert this:
    setup: B' L' Bw'
    fat-sune: Bw L B' L B L2 Bw' L2
    reverse: Bw L B
    2*3 moves setup + 8 moves fat-sune - 6 moves cancellation = 8 moves to solve the 3E3C

    Ooh, very cool. I think it should be D2 instead of L2 at the end of the fat sune though.

    It's L2 because I wrote Bw instead of F.

    Yes! I just got a new single PB for FMC, and it is 26 moves:) I got it for the weekly competition, and I have to say that I wish all scrambles were like this one;) I really like the fact that I was able to get to AB4C3E in 19 moves and the fact that I was able to cancel 9 moves in 2 out of the 3 insertions. I just wish that my 2nd insertion was better, but all in all it is a good solve for me.
    Scramble: R' U' F D2 B2 R2 D2 B U2 B' D2 U2 B' D2 R B R U' L D2 L R' F L' R' U' F

    R' L U F D L' F2 L B L2 - 2x2x3 [10/10]
    R' F U F R F' R' U' R2 - AB4C3E [9/19]

    1st Skeleton - R' L U F D $ L' F2 L B L2 R' F U F R F' R' U' R2
    Insert at $ B L' F2 L B' L' F2 L (Cancels 9 moves) Really Good

    2nd Skeleton - R' L U F D B % L' F2 L' R' F U F R F' R' U' R2
    Insert at % B2 D F2 D' B2 D F2 D' (cancels 1 move) Really Bad

    3rd Skeleton - R' L U F D B' D F2 D' & B2 D F2 D' L' F2 L' R' F U F R F' R' U' R2
    Insert at & D F2 D' F' B R F2 R' F B' (Cancels 9 moves) Again, Really Good!

    Final solution -
    R' L U F D F' R F2 R' F B D F2 D' L' F2 L' R' F U F R F' R' U' R2 (26 moves)

    I have been practicing FMC a lot recently, and not many other events, but since Nationals is only a few weeks away, I think that I should now focus on the events that I will be doing at Nationals:p. After Nationals I think that I will try to get back into FMC, because I am really enjoying it.
     
  17. A scramble from Dadams. Done at July 3rd, but forgot to submit. Using only A B A' (except for very first and last part) was intended.

    Scramble: R' L' D' U' B2 F' L R U2 F2 B' R' B' L U2 D' L R' F' L
    B F' L2 U B' // 2x2x2 (6/6)
    L U2 L' // build lDF, orient bLU (4/10)
    R U' R' // orient UB (3/13)
    U' F2 U // build bDL, orient lDF (4/17)
    F' U F // orient dRF (3/20)
    F U' F' // build dFL, orient bDL (3/23)
    U2 L U2 // build fRU (5/28)
    U' L' U L U2 // finish (3/31)

    So what's the idea behind the ABA' structure...? Was it just something you wanted to try, or is it a particular method...?
     
  19. This was just one of my experiments. The idea was come while guessing about DeepCube's method.

    This scramble is very hard for me. I only found a 32 moves solution.
