What's up guys, I posted here a few weeks ago about getting my first sub 40 solve, and I'm proud to announce that I just got my first sub 30 solve today (albeit very lucky)! Thought I'd share it with you so, here it is:

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

F’ B2 U F R’ B2 //222 (6/6)
B L’ B’ pre-move L //Pseudo 223 (4/9)
(F’ U2 F U’ F2 U2) //F2L-1 (6/15)
(L’ U L U2 F’ U F2) //EO + Edge Permutation + Last Slot (7/22)

^I got really lucky here. I was really stoked when I realized that this left me with just a 3c insertion.

Skeleton (22):
F’ B2 * U F R’ B’ L’ B’ F2 U’ F U2 L’ U’ L U2 F2 U F’ U2 F L

* = R’ D’ R U R’ D R U’ //3c (8-2)

Solution (28 Moves):

F’ B2 R’ D’ R U R’ D R F R’ B’ L’ B’ F2 U’ F U2 L’ U’ L U2 F2 U F’ U2 F L

Thanks for reading everyone! As before, any tips for improvement are much appreciated!

I got an interesting scramble during a 3x3 practice session. During my solve, I got to a point where all the edges were solved quite quickly which was very distracting. It made me wonder if there was any cool solution that could be applied using FMC. I've been quite rusty with this event, so I thought I would post it so others could take a look.

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

My start to a solution:

Cross: F' D' R' F'

First pair: U L' U' L2 U L' U

This left me with all my edges solved, and 5 corners left. I have not checked the inverse, but it feels like there should be something better that you can do with this. Not sure where else to take it from here, but thought I'd post it for anyone who wants to tinker around with it.

Just using insertion finder on that skeleton leads to a 22 solution: https://fewestmov.es/if/e1712605908da82fdf257f43c66b6f23

The two insertions are nested, but given that the first one cancels 2 it seems like it would be not be too hard to find.

Some useless 7-cycle insertion idea:

When you have a 7-cycle (A B C D E F G) left to solve, you could start by inserting any one of (A B C), (B C D), … (E F G), (F G A) or (G A B) to reduce it to a 5-cycle, and thereby finish it with two more insertions. But that's not the only way to do a 7-cycle with three insertions; you could also insert any of (A B E), (B C F), …, (F G C), (G A D) to reduce it to two disjoint 3-cycles, and continue from there.

(This is probably useless because any time you can do this "split" insertion, unless the optimal insertions are nested, the final result will be the same thing as just doing three normal insertions anyway. Also who even does 7c skeletons?)
