Singapore Cube Championship 2018

2018-02-24 ~ 2018-02-25

comment at the time: Got three 28-move solves at SG Cube Championship 2018! (… but two of them were for the same scramble lol) Really happy about getting a sub-30 official average (by the smallest possible margin, with a 29.67) after a drought of sub-30 singles at home.

Final

#3Mean29.67Single28 (28 / 33 / 28)

Attempt 1

Scramble

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

Results

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

L' U F D2 B2 // blocks (5/5)
(L') // moar blox (1/6)
R2 U2 // arrange blocks (2/8)
F' D F2 D' F' // set up edges (5/13)
U L2 U2 // ab5c (3/16)

Skeleton: L' # U F D2 B2 @ R2 U2 F' D F2 D' F' U L2 U2 L
@ = [B2, L' F L] // 2 cancel
# = [L F2 L', B2] // 2 cancel (16-4/28)

Missed optimal insertions (26 moves) because I'm dumb.

Another 28-mover (the one I actually wrote down, because ZBLL style points):
(L' U B) // two squares + pair (3/3)
L' U B' U2 L2 // eoxxcross (5/8)
F D' F' D F D' F2 D' F // F2L (9/17)
F' D' R' D2 R D F L D L' D' L D' L' // optimal ZBLL (14-3/28)

Attempt 2

Scramble

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

Results

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

(U2 B2 U' B) // pseudo222 + two pairs (4/4)
L2 U R F D' F D // pseudo223 (7/11)
(R' F' U' B U B') // xxxcross (6/17)
(U F' U' F U R U R' U2) // ZBLS; ab3c (9/26)

Skeleton: L2 U R F D' F D U2 R U' R' U' F' U F U' B U' B' U F R B' U B2 @ U2
@ = [R2, U' L' U] // 1 cancel (8-1/33)

26-move ab3c isn't that good, but I was kinda desperate. (I think? I actually don't remember much of what went on at the comp because I've been so sleep deprived lately.)

Backup (36 moves, but ZBLL style points again!):
F' (B L2 B2) R' // xcross (5/5)
F L F' L2 U L U' // second slot (7/12)
B' U B U2 F' L' F U // eo + third slot (8/20)
L' F L F' // last slot (4/24)
U L U' L F2 D F2 D' L' D' L D // optimal ZBLL (12/36)

Attempt 3

I immediately saw the three-move 222 block on inverse after doing the scramble, but my first solution (29) started with the normal scramble anyway.

First solution (29):
L B2 R' B' R' @ B // pseudo223 (6/6)
(L2) // align (1/7)
(F2 U L R' F' L' R) // eo + F2L-1 (7/14)
(F U F' U2 F U F' U' F U2) // F2L; ab3c (10/24)
@ = [R', B L' B'] // 3 cancel (8-3/29)

Second solution (28):
(F2 B2 R2) // 222 (3/3)
(F D F' D) // pseudo223 + three pairs (4/7)
D L2 D F' L // eo + F2L-1 (5/12)
L' F' L F' L' F2 L // tripod (7-3/16)
D F D' F' D F D' // edges; ab3c (7-1/22)

Skeleton: D L2 D F2 L F' L' F2 L D F D' F' @ D F D2 F D' F' R2 B2 F2
@ = [F' U' F, D2] // 2 cancel (8-2/28)

Also found an OCLL skip into J perm based on the above start, but it's 30 moves and I found it after the 29-move solution, so it's useless.
(F2 B2 R2 F D F' D) D L2 D F' L // above (12/12)
F' D F2 D' F2 D F D' // F2L (8/20)
R2 D' F' D R2 U' B U' B' U2 // J perm (10/30)

For some reason I didn't think to check (L2 R2 B2) as a start even though I had a lot of time left.
