Found an xxcross here, decided to try FM:

B2 U' B R U' F // xxcross
U' L . U L2 U2 L // F2L-1
U2 B' U B U L U L' // L3C

Insert B' D2 B U2 B' D2 B U2 at dot to cancel 1 move.

Final Solution: B2 U' B R U' F U' L B' D2 B U2 B' D2 B U' L2 U2 L U2 B' U B U L U L' (27 HTM)

[theZcuber]

Sure, go ahead and laugh at me for not making use of the 2x2x1 (and 3 move 2x2x2), but I still got a 19 move solution on it

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

U' L' B L B2 // 2x2x2 (5/5)
F2 L' . D' L2 D' // 2x2x3 (5/10)
L F L2 U L U' // Leaves 3C (6/16)

. = R D' L' D R' D' L D

19 move solution
B U R' // 1x2x3 (3/3)
R2 F' B U2 // 2x2x3 (4/7-1)
D B L B' L' // Slot (5/12-1)
F2 U L U' L' // Blockbuilding stuff (5/17-1)
F2 L' D' // Solve (3/20-1)

B U R F' B U2 D B L B' L' F2 U L U' L' F2 L' D'

Could someone show me how to do the actual insertions using my crappy skeleton? I found algs to do it(though they do not cancel much) and I do not know how to insert them.

B2 D2 L2 F2 R2 D L2 U B2 L2 U' F' L F U L U2 F D L2 U

R' U' B' D2 L' D' L U'
R' B R B'
D L' F L F' D' R' D' R D' F2
Insert at *: R2 D2 R' U2 R D2 R' U2 R'
Insert at !:*R2 B2 R' F2 R B2 R' F2 R'

I'm such a noob.

[Jakube]

Do not use 9-movers for insertion. Use pure 8-move commutator.

Insertion-Finder found this:

R' U' B' D2 [@1] L' D' L U' R' B R B' D L' F L F' D' R' D' R D' F2
Insert at @1: L' F' R' F L F' R F
After the 1st insertion: R' U' B' D2 L' F' R' F [@2] L F' R F L' D' L U' R' B R B' D L' F L F' D' R' D' R D' F2
Insert at @2: F R F' L F R' F' L'
Fewest moves: 35. 4 moves cancelled
The final solution: R' U' B' D2 L' F' R' F2 R F' L F R' F2 R F L' D' L U' R' B R B' D L' F L F' D' R' D' R D' F2

I'm such a noob.

Do not learn algs for 3-cycles, learn how commutators work.
Regarding the specific algs you posted:
Apart from being one move longer than desired you are now limiting yourself to cycles were the pieces need to be on one face.


We're all noobs

Hi today on Per's FMC forum (fmc.mustcube.net) a 20-solution is posted by Guillermo Sacristan.

scramble: B' U2 L2 U' B2 D U' R L2 U2 B' U' D2 B' L D2 B R' L' F' B L' B L2 D2 R2 F' R2 U D
solution: F B R2 D L F2 L B' L D' B2 L U' R D2 L' D2 F2 D2 L
his explanation:
F R2 D L F2 L2 D' B2 L U' R 2X2X2 WHITE-ORANGE-GREEN
F (B) R2 D L F2 L (B') L D' B2 L U' R ARMONIZE WITH INSERCTIONS
D2 L' D2 F2 2X2X3
D2 L FINISH

In my opinion he is cheating. He explains the last easy 6 moves but not the first 14 moves, the difficult ones.
No insertions, premoves, invertions, or whatever new tricks explained we don't know yet.

Secondly I found two guys (?) on the spanish FMC forum (www.rubikfm.es) that post similar cheating-like solutions for a couple of weeks now.
For example last week;

In my opinion, beautiful blend beautiful resolution.

his explanation (again translated bij google translate
Hi, solution of 20 moves. I've got less than half an hour, but as I liked to have started with a short block, do not try to improve it. I start with a block of 7 movements DBR:
D L F U R U' R2
I 3 insertions (4 movements more)
(U2) D L U2 (L2) U' R U (L2) F' R2
I end with 9 movements more:
U F' L2 - F2 U' L2 - U F2 U
U F' L2 create 2 blocks 1x2x2 though one is going to break
F2 U 'L2 creates a block of 2x2x3 even momentarily breaks a 1x2x2 blocks.
U F2 U ended
----------------------------------

Each week Crisi and LOGOS heave similar short solutions, 20 moves or less.
BTW: the spanish record is 28 moves.

What do my FMC-friends on this forum think about it?

What do my FMC-friends on this forum think about it?

I just went through all the solves, and the beginning makes no sense at all. There are tons of solutions for the step they did under the length that they solved it in, yet they chose lengthier solutions, which phased the rest of the puzzle. There's absolutely no way they found that by hand

Definitely uses a solvet, then try to hide it with "insertions" of single moves...

What do my FMC-friends on this forum think about it?

I think they used Cube Explorer in the following way:

1. Pick a few moves for premoves (1st one: D2 L, 2nd one: F L', 3rd one: U F2 U)
2. Enter the premoves + the given scramble to Cube Explorer as maneuver, and push "Apply" then "Add and Solve"
3. Push the triangle button several times until they are satisfied

You can reproduce their solutions in this way.
And the mission is completed by writing some explanation and posting the solution.

I think, Tomoaki’s conclusion it’s reality.
