This is my first attempt ever. I got to f2l -1 and spent like 20 minutes trying to find any sort of decent continuation, but they all kinda sucked. My plan was get something that solves edges then try my hand at an insertion. Ran out of time though before finding anything half decent, so I'll just post up to F2l-1


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

U2 L2 R2 D U L’ //2x2 6/6

R F’ R U F2 U2 F U F’ //3x2 9/15

U’ R U’ F’ R’ U2 R F U’ //F2l -1 9/24

Any critiques or suggestions welcome! I need to go read through a bunch of good solves now. I don't really get last layer and how it should be done yet.

That was fun! Not sure if I can see my self doing much other than if it's at a comp just because of the time.

Read sebastianos complete FMC tutorial. it seems long but is really easy to read and helps a ton.

Hey Garrett, :)
You can experiment with Pseudo blocks and premoves.

After your 2x2x2,
U' R' // makes an additional 2x2x1
then a U2 makes it a 2x2x3. In order to make it fixed, if you add a U2 as a premove before the scramble (a U2 is because that is the moves the block is offset by compared to the 2x2x2).
It helps make it a 10move 2x2x3 instead of 15.

I don't have time to continue but I can private message you about it when I have more time later.

Thanks Walker! I don't have time to go through all of this currently, but I'll definitely go through it later.
 
Attempt two. The first 2x2x2 is not great, but OLL skip into J perm. Couldn't see a way to solve edges instead. Don't understand how someone goes about that.

L' D2 R' D2 R' B2 D2 U2 B' R2 B2 L' B R D' B L D'

L R U’ R2 L2 F D L2 // 2x2x2 8/8

F’ U’ R U L’ U’ L // 2x2x3 7/15

U2 R U R’ U R’ // F2l - 1 6/21

U B U’ B2 // F2l + OLL skip 4/25

U’ B L B’ U’ B U B L’ B2 U B // PLL12/37

In that case I would have gone for the OLL skip into J perm too. A 37 is good enough considering your F2L-1 is 21 moves. And it hurts to destroy the square and pair.
To solve edges I would make sure EO is already done and two out of three LL edges are correct in relation to each other, then do one trigger.
For example:
U B U B' //set up orange and green edge
U B U B' //solve edges with one trigger
And one of the corners even gets solved.
With that skeleton you could get a final solution of 36 moves according to Insertion Finder.
Generally when I do FMC I try out different F2L-1s until I find one where the edges are solvable with one trigger. Especially when EO is already done there is almost always a solution like that.

Where does this happen? Orange green gets solved as part of the F2l-1

Full skeleton:

L R U’ R2 L2 F D L2 // 2x2x2 8/8
F’ U’ R U L’ U’ L // 2x2x3 7/15
U2 R U R’ U R’ // F2l - 1 6/21
U B U B' //set up orange and green edge
U B U B' //solve edges with one trigger

I actually mean orange-white and green-white edges here. Sorry, I should have clarified this, I was only thinking about LL edges and thought it was obvious when it wasn't. ^^
 
This scramble is very nice, but I didn't manage a good result. Still a very interesting solution by my standards.

Just tried the scrambles from Phillips Exeter Cube Day 2016 because I couldn't make it to the comp, and got a 31.00 mean rip (would have won by 3.33)

OK solution to 5 corners I guess, and according to IF I found optimal insertions so yay

Not that great of a skeleton to 4 corners, but I got lazy :p
Optimal insertions once again

Pretty cool 2x2x3, and could have tried to find a better solution to 3 corners but again I was lazy
Wish the insertion was better, doing niklas at L3C would have also given 26 lol

Anything I could improve on in my solves?
hopefully there aren't any typos

Help. I eventually got a 26 but it seems kinda bad considering how good the start is.

See this: http://mf.qiyuuu.com/cube/if/405a09f4cdc30326ceef35ca54fa336d.cube I searched it manually.
But I don't think human could find such insertions in short time.
 
<R,U> scrambles, <R,U> solving, anyone?


Example 1:

R2 U2 R' U R2 U R U R U' R2 U' R' U R U2 R' U R U2 R2 U2 R2 U R' // scramble
R U' R2 U2 R2 U2 R' U' R U2 R' U' R U R2 U R' U' R' U' R2 U' R U2 R2 // inverse

Notice that there is a 2x2 square in FRD that can be solved with <R2,U>. I attempt to reduce the remainder of the pieces. Then I get lucky with my finish
(U2 R' U' R) // Summer Variation setup using WBO and GR as the pseudo pair
(U2 R' U R U R' U R) // SV
(R2 U2 R2 U' R2 U) // finish the solve...

U' R2 U R2 U2 R U' R U' R' U' R U2 R' U R U2 // final solution


Example 2:

R U R U' R' U R' U2 R U' R' U2 R' U' R U R2 U2 R2 U2 // scramble

Corners are just one move away from being reduced to <R2,U> so to me it makes sense to solve corners first.
R U2 R2 U' = R U2 R $ R U' // solve corners and 2 edges and leave a 5 edge cycle
$ = U R2 U2 R2 U2 R2 U // insert a 2+2 swap to solve 2 of the 5 edges and leave a 3 edge cycle

R U2 R U R2 U2 R2 U2 R2 % U R U'
% = R' U' R' U' R U R U R U'

R U2 R U R2 U2 R2 U2 R U' R' U' R U R U R2 U' // final solution

If you insert the edge comm before the F2 it still works and cancels a move
