I might have missed something, but inserting D2 Dw2 at the beginning leaves 4x4e4c.
There aren't any easy conjugates with M2 as the interchange after that.
I think you should rNISS this.

All the solutions had pretty lucky domino finishes, but I'm very happy with being national champion

Don't have my sheet so idk what the insertions canceled but it was 6 total, missed optimal on 3c oops

Struggled a bit with this scramble, had some nice starts that led nowhere. Ended up using this stupid linear skeleton that I found within 2 minutes of starting on inverse.

2. 26

Spoiler

(B) D' B // EO, B' gives sq and 1 more move to a 2nd sq but couldn't find anything
R U R U2 // 222
L2 F2 L' D' L // 3e3c (12)
10-3 and 8-1 for 26, optimal was 25 with 10-2 nesting 8-3

This attempt really annoyed me. Scramble looked super nice with 3 pairs along with a 1 move square and multiple 2 move ones but I only ended up with a 26 because of terrible insertion luck. In addition to that, after (B) D' B R U R U2 L2 F2 there's an 8 move continuation to 3c that I missed, and optimal for that was 23 :/

3. 28

Spoiler

(U2 R) R2 B2 R // EO
U L2 (F') // 222
D' B' (D B') // 223
D2 R2 F D2 F' D' // L5C (18)
Canceled 3 and 3 for 28

Also had this 18 to 4c but optimal was 29 which I found during the attempt :/
(U2 F R' U2 F) // 2 sqs
D2 R' U' (U2) // 223
(L' U B2 U' B' U B U' L') // L4C
Canceled 3 and 2

Yet another hard scramble in my opinion, especially for a mainly EO solver like myself. Took me about 10 minutes to even find an EO that I was satisfied with continuing on. In hindsight I should've looked at the L2 start giving 2 pairs some more, but with how little I do block starts I wanted to try and stick with EO during the attempt. When I did decide to try block starts the 4c skeleton was the first thing I found then I messed around with the 223 a bit more before deciding to stop.

Overall, this mean definitely wasn't what I'd hoped for going into Nats, but I feel like I put too much pressure on myself to do well based on my results at Nats 2018 and Worlds 2019. These scrambles were pretty hard overall in my opinion and that combined with my lack of focus at certain points in solves resulted in a sub-par showing.

Congrats to Cale, Zac, and Mark for podiuming, and hopefully I'll be back on the podium next year

I need help. I am doing my first ever fmc solve but I have a few questions on how to do some things and if I’m doing things right. First, I’m using niss in this solve but I don’t know if I’m doing stuff right here is the solve. ( i have not finished it trying to find a good last com) this is also a standard CFOP solve so not to effective.

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

U R2 B’ F’ L F// Cross (6) normal scramble
F’ U F// F2L 1 (3) found with inverse scramble
R’ U2 R B’ U2 B// F2L 2 (6) normal scramble
B U’ B’ R’ U’ R// F2L 3 (6) normal scramble
U2 L’ U L U2 L’ U’ L// Rest of skeleton (8) Inverse
R’ U L’ U’ R U L U’// Comm that leads into a 3c case (8) inverse

And this is where I’m stuck. Also someone please tell me how to make my final solution work?

First ever FMC solve and you already know NISS? Alright!

So to get your final solution when using NISS, apply all of the moves you did in the normal scramble and then the inverse of all of the moves you found on the inverse scramble.
It's standard FMC notation to write moves done on the inverse scramble in parenthesis (). And also, I see you using ’ instead of ' for your prime moves. Subtle difference, but very important.

This is what your solve would look like-

U R2 B' F' L F // Cross (6/6)
(F' U F) // F2L 1 (3/9)
R' U2 R B' U2 B // F2L 2 (6/15)
B U' B' R' U' R // F2L 3 (6/21)
(U2 L' U L U2 L' U' L) // Rest of skeleton (8/29)
(R' U L' U' R U L U') // Comm that leads into a 3c case (8/37)

3c Skeleton: U R2 B' F' L F R' U2 R B' U2 B2 U' B' R' U' R U L' U' R' U L U' R L' U L U2 L' U' L U2 F' U' F

And now you haven't inserted your corner commutator yet, so I'll just let IF take care of that
U R2 B' F' L F R' U2 R B' U2 B2 U' B' R' U' R U L' U' R' U L U' R L' U L U2 L' U' L U2 F' U' F
L F' R F L' F' R' F (8-2)
(As a challenge, try to find your very own 3 corner insertion that cancels 1 move!)
And then write out the final solution: U R2 B' L F' R F L' F' R' L F R' U2 R B' U2 B2 U' B' R' U' R U L' U' R' U L U' R L' U L U2 L' U' L U2 F' U' F (42)

If you just want to generally get better at FMC, I'd highly recommend Sebastiano's FMC Tutorial. Good luck with FMC!

Using no rotations makes it a lot easier, but it takes a little bit to get used to it.
Instead of thinking, for example, the top face is white and the front face is green, instead think that the white face is U and the green face is F.
