27 and 30 move FMC solves that are pretty straightforward lol

27: B2 F2 U L2 B2 U B2 U' B2 F' R D' L' R' B' F2 R D2 B2 L'

Spoiler

L U' R2 F R//2x2x2
B' L R B L' B' R'//XXcross
U' D' B D B'//insert pair
L' U//F2L
U' L' F' L2 F L' F' L2 F L U//LL
Final: L U' R2 F R B' R L B L' B' R' U' D' B D B' L2 F' L2 F L' F' L2 F L U(27)

Pretty nice multislotting to finish F2L, and nice 1LLL case with cancellations

30: L' B' R L2 U2 D F2 U2 B D2 F2 R2 D L2 U' R2 U L2 U' F2

Spoiler

on inverse,
U' B L R F2//1 move to Xcross
D' R2 D//1 move to XXcross
R2 D R2 B R B'//F2L-1, EO
D' B F D' B' D F'//insert last pair, OLL skip
F D2 F' D' F D2 B' D F' D' B D'//J perm
Final: D B' D F D' B D2 F' D F D B D F' B' D B R' B' R2 D' R2 D' R2 D F2 R' L' B' U (30)
Was trying to create some blocks on LL and the pair decided to sort itself out too, lol

Find the CMLL skip and you will be my best friend:

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

z x R' Uw' F' R2 U' // first block
??? // SB

EO for LSE was a four flip

 

[TheCoolMinxer]

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

(L D2 B U' L' U2 L2) //2x2x2
B U //2x2x3
(B R' B R B) //F2L-1
D' R 'F D' F' D2 //L5C
my skeleton so far: B' U' D' R' F D' F' @ D2 B' R' B' R B' L2 U2 L U B' D2 L'
I don't know how to do insertions with 5 corners, so I solved 2 wih a comm after the skeleton: U F U' B2 U F' U' B2
then insert @= F' D B' D' F D B D', cancels 2 moves yay

final solution: B' U' D' R' F D' F2 D B' D' F D B D B' R' B' R B' L2 U2 L U B' D2 L' U F U' B2 U F' U' B2 (34 moves.)

does somebody want to finish the skeleton (inserting the 5 corners), sub30 could be possible (?).
Still, I am proud of myself that I found a nice skeleton, considering the very bad scramble/start

Some of the craziest scrambles I have seen at a comp so far:
R' U' F R2 U2 B2 L2 D2 B2 U' R2 F R2 D2 B2 R B2 R2 D' B F D' R' U' F

Scramble is from N8W8 Summer 2016, how about to have a look?

I only found a 24 (at home, was not at the comp), which is kind of disappointing.

Some of the craziest scrambles I have seen at a comp so far:
R' U' F R2 U2 B2 L2 D2 B2 U' R2 F R2 D2 B2 R B2 R2 D' B F D' R' U' F

Scramble is from N8W8 Summer 2016, how about to have a look?

I only found a 24 (at home, was not at the comp), which is kind of disappointing.

I haven't spent much time on it but I came up with this silly thing which solves F2L-2E and leaves you with 20 moves to 5E if you want
(F D B R' U R D' U' R U R') //11
(F U2 F2 L F L' F U2 F') //20
IF can only cancel 2 moves from insertions though :/

Just found this, however:

D2 B' D' R D' U' R2 // 223 or Pseudo F2L-1 (7/7)
U //F2L-1 (1/8) !!

 

[Cale S]

I found a 23 which is 21 in STM (just like my official pb)

D2 B' D' R U' D' R2 U // F2L - 1
(L F' L' F2) // some stuff

D2 B' D' R U' D' R2 U F2 @ L F L'
@ = R U L' U' R' L F' L F L' // to L3C

D2 B' D' R # U' D' R2 U F2 R U L' U' R' L F' L F2 L'
# = [R' D' R, U2]

Final solution: D2 B' D2 R U2 R' D R U D' R2 U F2 R U L' U' R' L F' L F2 L'

I have found a 25

On inverse
D2 B' U L2 U' B2 D2

Another 25

Spoiler

D2 B' D2
R U' R2
D R' D' U
F L F' L'
F * L F2 L' F
* = F2 L' B L F2 L' B' L

And some nice skeletons. All but 3 edges and 3 corners in 13

Spoiler

(F R U R U)
(R D B')
D B U' B' U
(IF finishes in 25)

And all but 7 edges and 3 corners in 4 moves

@ R' U' R2 * F

@ = F' B U2 F B' R2
* = U' F + D F' U F D' F'
+ = F2 D U' R2 & U D'
& = B' R' L U2 R L' B'

But the insertions I have found give a 26.

Has anyone tried a pure comms FMC before? Not saying it would be good but it could be interesting like a very well cancelled 3-style solve.

Edge comms use slice moves a lot, resulting in lengthy solutions.

 

[shadowslice e]

Edge comms use slice moves a lot, resulting in lengthy solutions.

Well, I didn't say it would be good but it would be interesting to study. Plus a perfectly cancelled set would likely be close to if not optimal in almost every single circumstance (I'm not saying that you have to do edge->corners or vice versa but you can interlink them.

 

[Daniel Lin]

Edge comms use slice moves a lot, resulting in lengthy solutions.

not really, usually just 1-2 more moves. And plus for edges you can move the moves around like R' L F2 R L' U2=L F2 R L' U2 R, which gives more possibilities

Plus a perfectly cancelled set would likely be close to if not optimal in almost every single circumstance

how do you know? regular 3style is almost 100 moves STM, I don't think you could get sub 30 just by doing cycles differently

 

[Cale S]

this is a fun scramble:
L' F2 D2 B2 U2 R D2 L' D2 U2 L' U' F' D' L R2 D' B2 U R'

found two 24's, went with this one:
(U R' B') // EO + pairs
(D' R U' R L D L' D) // to 3e4c

D L % D' L' R' @ U R' D ^ B R U'
@ = R L' B2 R' L U2 // edge cycle, 13 to 4 corners
^ = [D', B U' B']
% = [L, B R2 B']

Final solution: D' L2 B R2 B' L' B R2 B' D' L2 B2 R' L U' R' B U' B' D B U R U'
24 moves


13 to 4 corners is pretty good

My solution on Cross-strait Cubing Exchange 2016. I got the first runner-up with all results are 27 moves.

A while ago I posted a noobish 40 moves solve with OLL+PLL and asked for advice. I'm doing the same again now except that I improved a bit.

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

B2 R U F' //square (4/4)
L U' L2 //another square (3/7)
U R2 //2x2x3 (2/9)
F2 D' F' //yet another square (3/12)
D' //pseudo F2L-1, premove D2 (1/13)
(F' D' F2 D) //orient an edge (4/17)
(D R' D' R F) // to L5C (cancels to 4/21)
D2 //undo premove (1/22)

Skeleton: B2 R U F' L @ U' L2 U R2 F2 D' F' # D' F' R' D R D2 F2 D F D2 (22 moves)

@ = [R, U' L' U]
# = [B, D' F' D]

Solution: B2 R U F' L R U' L' U R' U' L' U R2 F2 D' F' B D' F' D B' D' R' D R D2 F2 D F D2 (31 moves, cancelled 7)

Apparently my insertions were optimal. pb by far btw, went from 37 to 31.

 

[Cale S]

the first scramble of Michigan 2016 is really nice

Spoiler

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

first I found this 25 in about 15 minutes

(B' U2) // two squares
F' B2 (B2 F2) // 2x2x3
B L B' U (U) // F2L - 1
(L2 U' F U F') // EO + pair setup
F' L2 F2 L2 F' L' F L' F' L' // insert pair + antisune

Final solution: F' B' L B' U F' L2 F2 L2 F' L' F L' F' L' F U' F' U L2 U' F2 B2 U2 B
25 moves


then I found 18 to 3 corners but optimal is only 25:

B U' // EO
(B' U2 R2) // roux block + square
R2 F2 B2 L' B F' // F2L - 1
F D2 F D2 R F2 R' D2 F2 // cool stuff to L3C

then I found 15 to good L6C, but insertions were bad

B L2 R' F // EO + square
@ D U2 R U2 // 2x2x3 + edges
@ = U R U' D' R D R' // to good L6C

Can someone find a good insertion for this? i suck at insertions and IF isn't working, idk why

weekly scramble:R L2 U2 L' F2 B L' F2 R' U2 F D' L F' B' L2 R F' U2 R'

I guess you could use an LL alg too, haven't found anything good tho
