The Roux "Example Solve" Game!

I just realized there was actually a pretty good lse in my first solution, I thought the best one was 16, man I'm dumb sometimes. I really need to improve my lse.

very nice solution, just get rid of that 2 look
 
Thanks, I've been working on SB efficiency a lot lately. I would have posted that same solution first had I seen the good lse, I instead resorted to inserting the last pair with a sledgehammer which gave me the 8 move lse, but unfortunately added 5 moves to SB. It's really hard to find a good balance sometimes, I'm starting to think I should just do the blocks as optimally as I can and just put up with bad lse cases, it's always pretty fast no matter how long it is. Still working on cmll too, I'm learning the pi cases as we speak.

In a speedsolve, I think one should aim for a short and fast F2B regardless the LSE. F2B (especially the second block) is the most important part of Roux.

First try (linear solve) with my standard colors:

y' x'
B' R2 B' U Rw' U' F //LB (7)
R' Rw' U' Rw U' R M F' U2 F Rw U Rw' // RB (13)
U F R U R' U' F' // CMLL (7)
M U2 M' U M' U2 M U2 M' U' M' U2 M U2 // LSE (14)

41 STM

Optimized it with NMCMLL, but i can't find a better LSE

y' x'
B' R2 B' R' F2 //RB (5)
Rw U' Rw U R2 U2 M U2 Rw (U R') //LB (11-2)
(R U) U2 R' U R U2 R' //NMCMLL (7-1)
U' M' U M U' M' U M' U2 M U' M2 U L2 //LSE (14)

34 STM, 41 HTM

I completely agree, and I think that's what I'll aim for from now on.

lol'd. I know, it's horrible isn't it? :p

Edit: ^ nmcmll is so win

The braces with the cancellation are executed too, now it should work

Thank you!
(There is nothing i wouldn't usually try, maybe the nmcmll confused me a little.)

I think you forgot to add the cube rotation in the beginning. I don't get even the first block.

There is no such thing as weird colors. :)

Solution

y' x'
R2 B2 U Rw' F U' M U' R U R U M' R B // RB + LB2x2 (15)
U' R' U2 R U' R' // LB (6)
y R' U' R U' R' U2 R y' // CMLL (7) rotations instead of AUF! much cheater!
U2 M' U M U2 M2 U' M U2 M // L6E (10)
// Total 38 STM

It was interesting trying to preserve some RB stuff while working on LB Not sure how many moves I saved, but things came together pretty ok. 21 move RB+LB isn't terrible.

M' R can be executed as r. So, 37 STM. :)

Edit 1:
How about this one. shorter by 2 moves. But, has E slice turns which I hate. :P

U2 R U2 R' U' R U' R' //CMLL (8)
M' U' M' U E2 M' E2 M //LSE (7)

y' x' It is. Same as GuRoux's and mine.

Surprisingly short SB... The LSE seems long, but I find it really fast.

Trial and error:

I'm not sure I found the shortest FB, but I liked the SB too much, so I kept the F2B, and experimented only with the CMLL and the LSE.
