Here's a dumb and silly FMC I did at home using a random tnoodle scramble:
It's a 34 done with NISS, I didn't have time to deal with insertions, so I just used a move optimal T-Perm that left me with no AUF to finish the solve. I still consider myself a medium level FMCer, so I'd like to know if anyone else has a way to either improve my solution, or come up with a better solution of their own. I'm really looking to improve my skills here.

I'm not the greatest FMC solver but I found an interesting skeleton which led me to my first sub-30. Could've been better but since I did this without stickers to find insertions I had to do L5C "by hand" which wasn't too hard due to the skeleton I found. Best Insertion Finder could get was 25 and I got a 29 so not too bad I guess.

34 moves is a pretty nice result, and its good that you know how to use NISS.

A way I could improve it is to do things differently after F2L-1. Generally you want to solve most of the pieces and do insertions, because insertions can be pretty powerful most times.
But sometimes you get an easy linear solve, it just depends. Here's what I found for F2L-1 continuation:

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

(17 moves to F2L-1)
L U L' U' L U' L' // F2L (6/23)
L' U2 L U L' U L // Sune (7/30)

Solution - B' R U' F R' F' R L U L' U' L U' L2 U2 L U L' U L B' U' L' B' L U L' U2 D' F
30 moves

At first I tried L U' L' to get me to a 2tc + 2e2e skeleton, but I realized I couldn’t easily get 34 moves or less with that kind of insertions.

I tried a couple other skeletons, but I still couldn’t find sub-30. I’m sure there is one out there to get this sub-30 I just didn’t find it.

If I used the same WV, but doing a 2c2e insertion instead of finishing with a T-perm, it surprisingly isn't better! I even checked Insertion Finder. So in this rare case, slapping an alg at the end is actually the optimal insertion!

Doing a completely different solution I can find this-
Scramble: R' U' F R2 F L2 U' R2 U R2 U' F2 R2 F2 L2 D' R' F' L R D2 R2 D2 R' U' F

B U' R' L' // EO (4/4)
D' B' U D2 F // DR (5/9)
(R2 L2 D') // HTOR (3/12)
(L2 U2 L2 U2) // AB2e2e (4/16)
16 to 2e2e

Skeleton- B U' R' L' D' B' U D2 F * U2 L2 U2 L2 D L2 R2
*= F2 R2 F2 U2 R2 F2 R2 U2 (8-3=5/21)

Solution- B U' R' L' D' B' U D2 F' [R2 F2 U2 R2 F2 R2 L2] U2 L2 D L2 R2 (21)
Replace [-------] with L2 B2 D2 R2 B2, overall 2 moves shorter.

Final Solution- B U' R' L' D' B' U D2 F' L2 B2 D2 R2 B2 U2 L2 D L2 R2 (19 moves!!)

Nineteen moves. Wow. Personal Best Single. I was not expecting that. Just wow.

Edit: I checked IF and I got the same optimal solution as it but with a suboptimal insertion, by replacing moves at the end. Interesting.

Hope that’s what you’re asking for, and GL with your FMC journey!

I see a lot of people doing DR solves now and I'm interested in learning it. I understand in general the steps but how to do it confuses me. I can do EO just fine but I can't figure out the domino reduction step. Can anyone point me to somewhere I can learn?

I'm currently working on a full guide about DR: I still do not have a realese date, but it's coming, trust me

Yeah, 19 to 3e3c isn’t usually good, but also, 4e5c in 17 isn’t better

I’d say that skeleton has no hope even after those complete cancellation insertion things, and IF also says 28 is the best possible for that.

I tried that scramble for about 3 minutes and I found this-

R2 D' // SQ
L F2 U F // EO
R // 222
L' B2 L2 U L B2 // F2L-1
EOF2L-1 in 13 moves

With that you can get a 14 to 3e5c, or a 16 to 3e4c, or a 17 to 5c, or a 18 to 3e3c, or a 22 to 4c, or a 25 to 3c.

I thought 13 moves to eoF2L-1 was good, but even with IF the best is 27.

I thought 13 moves to eoF2L-1 was good, but even with IF the best is 27. Darn.

Yeah Ik it’s not great, but I was curious to see if I could get anything good on it. Best IF gave for any of those was 27

Question: What stuff should i look out for after doing EO? I tend to miss good EO starts or find good continuations which is why 80-85% of my solves are blockbulding

cool! Whenever you switch while doing DR do you just try to orient as many pieces as possible and then switch(or finish)?

cool! Whenever you switch while doing DR do you just try to orient as many pieces as possible and then switch(or finish)?

I do DR in 3 main steps

1)EO
2)reduce to 4e4c, 2e3c, or 2e4c
3) setup to R, R U R'/R U' R', R U2 R', respectively

I switch between steps 1 and 2, and steps 2 and 3 mainly to try to get a better case if the DR setup looks bad

 

[WoowyBaby]

@guysensei1 Wow, you and Cale S have gotten very nice pure domino results, maybe what porkynator said was true (on pg. 245), domino being viable as a method itself. Maybe I'll try a ao12 of pure domino and see how it goes.

-----

I just got an insane solve today and I wanted to share it.
I did it in 3x3 Example Solve thread, so if you want to see the full post click here.

Since I wasn’t trying for purely fewest moves, I wanted it to just be a simple linear solution for the example solve thread, so this was way more unexpected than if I got this somewhere else.

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

Spoiler: Original Solution

First Solution:
L' D2 B R B' // Two Squares (5)
U' F // Edge Orientation (2)
R2 D2 R' D2 R D' F2 // Combine Blocks (7)
L' U L' U' L2 U L2 U // Finish (8)
22 HTM

This is an amazing solve and was my craziest solve until I found a way to save 2 moves off just a couple minutes later.
The first 13 moves of the second solution is the same as this.

Final Solution:
L' D2 B R B'
U' F
R2 D2 R' D2 R D'
U F2 D'
L' U L' D
20 moves.

Totally linear 20. It was just so unexpected because I wasn't even doing a serious FMC attempt.
I still can't get over this even though it was hours ago. I was shocked when I found it. It is the most incredible solve I've done.

 

[porkynator]

This is probably one of my craziest solves. The final result is good (25), but I was expecting something better given that wonderful start.

U' B' U B //CO, and corners are just 2 moves from solved (4/4)
(D2 L F' R' L D) //DR (6/10)
(R L') //3e2e2e (2/12)

Skeleton 1: U' B' U B * R' L D' L' R F L' D2
* = B2 L2 B2 R2 F2 R2 //2e2e (6-2/16)

Here I have a nice 2e2e, or so it seems. The new insertion finder gives 24 inserting a 1-move setup to an 8-move 2e2e case with 1 cancellation (and it gives 22 starting from Skeleton 1 without my first insertion, inserting first an 8-move 2e2e that cancels 4 and then a 6-0 3-cycle). I couldn't find any good insertion, but I saw that I could replace the last 7 moves with D' R L' F D2 to get a 5e case:

Skeleton 2: U' B' U B' * L2 B2 R2 + F2 R D' R L' F D2
* = E'
+ = [R' B' D' B: E] blah

Not very satisfied with this last insertion, I was hoping for something 1 or 2 moves better. However with this last skeleton I did beat the new insertion finder!

Solution: U' B' U B' U' D F2 L2 B L' D' L U D' B' D B R F2 R D' R L' F D2 (25)

I have also found this skeleton:
U' B' U B L' D2 //9e in 6 moves!

But I didn't try to insert. IF gives 21, but I couldn't find better than 25.[/spoiler[

Just got my PB ao12 of 24.50 and all using Domino. The first 9 solves are from another DR-only session and the last 3 are from the ongoing weekly facebook comp

Also this backup 26 is stupid:

(** L2 R2 U' R B2 L' U' R2 U)//DR (13)
(F2 * U2 L)//J perm+U perm (16)

*=(F2 U L U' F2 D R' D R D2)//3e (23)
**=(F B' U2 B F' L2)//solved (26)
