Second sub 30 inside of a week - very nice scramble (and a decent solution)

Scramble: L F L' F2 D' L2 U2 F' U' L2 U' R2 L2 B2 L2 B2 D2 B2 U' B2
Optimal Scramble (generated afterwards): U D2 F U' F B' D F2 U L2 D L' U' L U' F D

U2 B2 U' L2 B D' // X-Cross (6/6)
R2 U R2 U' R2 // Pair 2 (5/11)
F R U R' F' // Psuedo pair 3 + phasing (5/16)
R U' R' U2 F' U' F // Finish - Force LL Skip (7/23)

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

a 2x1 block already made so found an 8 move 2x2x3:L2 D'R U' F' U L' R,getting nothin so good after this.

After F2L you can do L then V perm on D face to save some moves.

My quick attempt with ilikecubing's start
Scramble: R' F' R' L' D2 L' R F' L D' F2 L B F' D' B L D F' D' R' U2 L B2 L'
2x2x3: L2 D' R U' F' U L' R (8)
EO: F L' U *L (12)
PseudoF2L: U F2 U' F2 U' (17)
LL edges to leave 3 corners: D F D' F D F2 D'
Correct pseudo: U' (25)
Insert at *: U R2 U' L U R2 U' L' to cancel 5 moves giving 28 moves
I had 2 other 26 move skeletons (using other sune finishes) to insert, so cancelling this many isn't too lucky.

Or 2x2x3: L2 D' R U' F' U L' R (8)
EO: F2 R U' R' (12)
Leave 4 corners: F2 U2 F' U2 F' U F (19)
Insertion finder says that there's a possible 8 cancellations for the 2 insertions giving 27 moves
I'd actually back myself to find this one, as the 4 corners are a pure 2+2, so there's not too many combos to check for the first insertion.
 
Not really FMC, but you guys seems good at finding solutions.

I am trying to find my solution for my 11.50 OH single, the scramble was: D B2 U L2 U' L2 D' F' L2 D F2 R' D' U2 L2 B R F2 D'
hints: I made cross on yellow (aka. bottom for weird colour schemes) and the last 4 moves was sexy insertion(can't remember if it was R or L, but I'm pretty sure it was R)+U2 (AUF) I'm also kind of sure that the blue-orange F2L pair (blue-red for Aachen and my cube :3 ) got paired up during the other pairs so I could just put it down.

EDIT: found it... and WTF!?!?!?
inspection: z' y
cross: L U x y' U' L' U' z2 [5/5]
F2L#1: U2 L U' L' x y' L' U' L' U z [8/13]
F2L#2: U L U' L' x y' U' L' U x [7/20]
F2L#3: U' L U x [3/23]
F2L#4: L2 U' L' U [4/27]
LL: L2 [1/28]

EDIT2: corrected the solution to how I actually executed it
:3

Got a 21 move linear solution on a really stupid scramble someone on the German forum set his lucky PB with:

Scramble: L D2 R´ F´ L R2 B U´ F´ L U R´ D2 U´ F´ L2 U´ B´ R2 D2 L R´ B D2 F´

Solution: Triple X-Cross: R2 B U L2 U R U' B2 R'

moving blocks 'n pairs about is fun:

R2 F' // premove F2 makes roux block
B U B'U'B' // 3 squares
U2 L' F L2 F2 // pseudo F2L-1 premove F2 for LOL premove cancel
L' F U' // leaves 4 corners and edge swap
U F2 U' F' U F' U' F2 // Sune edge swap cancels three moves and leaves 4 corners
IF says the corners can be inserted with 10 cancellations for a 26 HTM solution :)
 
U L2 U F2 L2 D' U2 F2 L2 D2 L2 R' F D U2 R B2 U2 B' U R

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)
 
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.
 
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

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 :)
 
FMC-cheating by one or two spanish cubers?

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;

Posted by LOGOS (= same Guillermo ?):
----------------------------------
scramble: F' U2 F L2 U' L2 F2 D2 B2 U2 R' U L D L' U2 B D L' D' B' L U2 F
solution: D F L F R' B L2 U2 B L B2 R2 L' U R' U2 F L'
his (?) explanation (translated by google translate):
My friends.
D F L F R' B L2 B2 U2 R B L (12 turns) 2x2x2 YELLOW-RED-BLUE + 1x2x2 + 2 Pairs
R L' U R' (4 turns) 2x2x2 YELLOW-RED-BLUE HARMONIZED + 1x2x2 (2 mini-blocks) + 1x1x3 (2 mini-blocks) + 1 Pair
U2 (1 turn) 2x2x3 YELLOW-RED-BLUE-WHITE HARMONIZED
F L'(2 turns) FINAL SETTING
TOTAL: D F L F R' B L2 B2 R2 L U2 B L' U R' U2 F L' (19 - 1 = 18 turns)
In my opinion, beautiful blend beautiful resolution.
Greetings!
Guillermo (LOGOS)
----------------------------------

Again Guillermo explains the last 7 moves instead of the very crucial first 12 moves.

And on that same forum a solution from someone called Crisi
----------------------------------
scramble: F' U2 F L2 U' L2 F2 D2 B2 U2 R' U L D L' U2 B D L' D' B' L U2 F
solution: U2 D L U2 L2 U' R U L2 F' R2 U F' L2 F2 U' L2 U F2 U
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?

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

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. :rolleyes:

Why is this not working? Is there some special rule I can't find? Could someone please tell me what I am doing wrong so I can stop bothering this thread
