Forum weekly comp (2018-18)

Solution I submitted was a 29 because I'm a scrub and didn't see the amazing 16-move ab3e skeleton. (Why did I go back and play with the scramble even though I've submitted my solution? I have finals to study for…)

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

All on inverse:
F' B U L' // EO (4/4)
B2 F @ D' // 222 (3/7)
B F' U F' B' R2 // 223 (6/13)
F2 U2 F' // ab3e (3/16)
@ = F2 L2 D' L2 F2 R2 U' R2 // 3-cycle (8-1/23)
Solution: F U2 F2 R2 B F U' F B' D R2 U R2 F2 L2 D L2 F B2 L U' F B'

Looks like the three people who had 24-move solutions had the same start, although our 223 solutions were very slightly different; I split up the F2 move to form the red-blue-yellow square so as to get an extra square solved.

Also found a 23-move skeleton; optimal insertion would give 28.
U2 F B R' // EO (4/4)
U L2 D2 R2 U2 // 222 (5/9)
(F' D2) F2 D // 223 (4/13)
(D' F D) // pseudoF2L-1 (3-1/15)
R F2 R F' R' F' R F // F2L; ab3c (8/23)

EO-first rarely works out for me because I suck at EO blockbuilding, but I really should've tried it for this scramble. Oh well.

That F2L-1 was key
D2 U' R' F U F' //2x2x2 + 2x2x1 (6/6)
(R2 U') //PS F2L-1.5 (2/8)
(R' B2 R B' U2) //F2L-1 (5/13) -> this is was I was looking for hahah, that 1x1x3 block was driving me insane! XD
(B' D B' D' B2 D B2 D') //L3C (8/21)

IF gives 26 on this one
Thanks Kit for that

Here's another example of an amazing start (but i couldnt find anything):

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

L' D U2 F2 L F2 L'//Not very convincing... 2x2x2
R2 U R U2 R2 B'//um lolwut, 12 move f2l-1, 3 move pair, 15 move f2l(doesnt lead to anything nice)
Couldnt find anything, found 24 moves to L4C but wasnt cancelling much :/
the final solution was 35 :/
E: IF gives a 29 for my skelly xD

A decent continuation:
B U B' //EO (1/14) (two moves cancel)
U2 R' U' R U R' U' R U //2c twisted (9/23)

Not great, but better than L4C in 24, and it was quite easy to spot.

U2 R' U' R U R' U' R @ U // ab2c (9/23)
@ = [R F' D2 F R', U2] // corner twist insertion (12-2/33)

Probably can find a better insertion by doing 3-cycles, but :eff. Finishing the last few edges in the obvious way (U R' U R) leaves a bad ab5c case.

thanks @xyzzy and @porkynator

e: Did my first AB4C insertion! Cancelled only 2 tho, got a 37 and IF gave a 33... meh(for the weekly fmc)

Couldn't find a good insertion, had to be happy w/ 36. IF gives 34(which i was almost going to find but i thought it wouldn't cancel anything rip)

I wasn't very impressed with this, because I found these:

After 2x2
R F D R2 D'//makes better 2x2x3+edge, couldnt find anything good after this :///

or
(F' D R' D')//ps223
from here you can apply the premove or do:
F R//edge before premove
pls halp

I think your solution up through EO is pretty good. But after EO, you added 15 moves to get to 3 corners. You may have missed this, but the continuation to all edges solved works nicely like this:

D2 L F L//222
U F2 U2 L F2 L'//223
U F U'//EO
F2 R' F2 R2 F' // AB4C

IF gives a 29, which is pretty meh for 18 to 4c. My general advice would be to not necessarily have a plan going into FMC. I used to be very linear in the way I thought of each solution. So what I mean is that after 2x2x3+EO, you don't necessarily have to go to an F2L-1. Maybe experiment with solving the edges and it may give you way less moves, even if it gives you AB6C. Hope this helped a bit.

Thx! Yes, I've never really tried solving the edges by themselves, I always just go for an F2L-1 or solve random blocks.
I'll incorporate them into my solves(whenever needed) from now on!

Hey, so I'm reaaaaally noob (I just know NISS as a technique and comms) but I wanted to show you guys something and see if you could come up with something

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

So I started on Inverse Scramble:
D' R2 U R2 U' // X-Cross

Then back to normal:
D2 F D F’ D2 R’ D R2 D’ R’ // F2L-1 in 15 moves, not great, not bad for me
D2 L D L’ F’ D F // I solved the remaining edges and oriented the corners (not intendendly)

So it's L5C in 22 moves which is not incredibly bad for me. But the only thing I found in time was this:
R’ B’ R F2 R’ B R’ B’ L’ B R2 B’ L B F2 D // 16 moves for L5C which I guess it's not great

38 moves is not terrible for me, PB is 34

Any ideas on what to do after F2L-1 or how to improve those L5C?

Since you already know commutators, the main way to improve last corners is with insertions, inserting the corner commutators within the solve to cancel moves. Insertion finder says you can finish your solve (after a D move to AUF) with two 8-move commutators cancelling 4 moves for a total of 35 moves.

I found a slightly shorter step to solve the remaining edges from your F2L-1. Here's the full solve with insertions.

(D' R2 U R2 U') // (5/5) X-Cross, given
D2 F * D F' D2 R' D R2 D' R' // (10/15) F2L-1, given
D' F L' F' L D2 // (6/21) AB5C
Insert at *: L' @ U L D L' U' L D' // (6/27) Solves 2 corners
Insert at @: B U' F U B' U' F' U // (7/34) Solves remaining 3 corners

Solution: D2 F L' B U' F U B' U' F' U2 L D L' U' L F' D2 R' D R2 D' R' D' F L' F' L D2 U R2 U' R2 D (34 moves)

Some things to note: former NR was 30, and in this comp 4 attempts tied or beat that XD
Julián Schaffhauser got DNF 30 27, twice NR
Marcos got DNF 37 23 (wut), taking the NR
I got 35 31 29, not NR or anything Missed mo3 NR by 0.33 hahaha

So wcadb has messed up stuff for the fmc scrambles at indian nats 2018
1- correct
2- on this attempt, a competitor got scr.3 and didnt notice. at the 3rd attempt he noticed that he'd again got the third scramble, and we had to do a reattempt for the 3rd(luckily we were informed of this midway of the '3rd attempt'). I'm very sure that the scramble that that competitor got for the 2nd and attempt has been printed. So basically everyone did one scramble and he did another.
3- extra scramble, correct
(PS: Don't worry this was approved by the wca lol)

Whatever, I'll reconstruct my 30 anyway:
Actual Scramble: R' U' F R2 F2 R2 U2 B' R2 D2 R2 U2 L' F2 R' D2 B2 U B D' F L' F R' U' F

L// Pair 1/1
B' D B' D2 L//222 5/6

(F R' F R)//F2L-1 4/16
(F' R F' R' F2 R F2 R')//AB3E 8/24

At this point I had around 10-15 mins left and decided just to do the 10 move 3-cycle. But then I realised I could check the end of the skeleton for a lucky case.

Skeleton: L B' D B' D2 L R F2 R' F2 R F R' F R' F' R F' B' D2 B2 R' B' D *

At last! I finally got my first sub 30 FMC solution. I am really happy with this solution, especially since I was able to get to AB4C in just 21 moves. The scramble was from the Weekly Berkley FMC, so in case anyone is going to do it, I put it all in spoilers. I got this yesterday, but forgot to post it in this thread.
Also, I do not know if there is anything that you see that I should have thought about with this solution, but if you have any thoughts, I would be more the happy to hear them.

1st Skeleton: F B R2 D R' & U2 R2 U' B' L D B L' D' B' D B2 R' B' R D [21 moves]
