I don't think I have ever seen more accomplished in 3 side turns. Complete a block and do CMLL and do EO at the same time. I wish I could accomplish something like that.

I wish I was good enough to jump into LSE halfway through the 2nd block.

As you will note below, it takes me as long to do 2 blocks as it takes you to do the whole thing.

Next: L' F L' F' R' D2 R2 B' D B U' F' R2 D2 B' U2 B2 D' B2 D' L2 F' L F2 U'

Solution 1 (Non Matching Blocks):
x y2
R2 U2 F' D2 //FB (4/4)
r' M U' R2 //Pair + DR (4/8)
F' U F U2 r' U r2 //NM SB (Pseudo F2L + EO) [M] + Pinkie Pie [M'] (7/15)
l' U' L U' L' U2 L //CMLL (7/22)
M2 //LR (1/23)
U M' U2 M //4c (4/27)
L' //fix NM (1/28)

Solution 2 (Blocks simultaneously):
x'
R2 U' B D2 //Square right + Last Left Pair (4/4)
L U' L2 U' F //Block left (5/9)
L F' L' //Block right (3/12)
L' U' L U l M2 F' L' F //CMLL (9-1/20)

l2 F U2 R U r2 F' //FB+SS (7/8)

I’ve only been doing Roux seriously for about 2 days- can I have help with some efficient tricks?
Here’s what I’d do in a solve:

z2 x
u2 U’ M’ U’ M U’ // First Block
x’ r’ U M’ U’ r’ U’ R U2 R U r’ U’ R // Second Square
R U2 M2 U’ R’ U’ r U r’ // Second Pair
U2 R’ U’ R U’ R’ U2 R // CMLL
U M U’ M’ M’ U2 M’ U M2 U2 M’ U2 M // LSE

Different solution with same scramble-
x’
r’ U’ M’ U M U’ l’ U’ l y // First Block
R’ U R2 U’ R U R’ // Second Square
U R’ U’ R U M’ U2 R’ U R // Second Pair
U R U2 R’ U’ R U R’ U2 R’ F R F’ // CMLL
M2 U M U2 M’ U M’ U2 M2 U’ M U2 M’ U’ // LSE

Next Scramble: F R B2 L2 F2 R2 U2 F2 U' R2 D L2 U L2 R' F' D2 B R' B2 F2

29 STM (1 move cancelled):
E r' B //2 Pairs FB (3/3)
U2 r' E' //FS+Pair SB (3/6)
F' R' F //FB+SS (3/9)
M R U R' //SB (4/13)
M' U //setup OLLCP (2/15)
r' U' R U' R' U2 r //CMLL+EO (7/22)
M U2 M U //LR (4-1/25)
D2 M' D2 M' //EP (4/29)

another CMLL - 27 STM (3 moves cancelled):
M R U R' //SB (4-2/10)
R U R2 F R F2 U F //CMLL (8-1/18)
U' M //EO (2/20)
U M2 //BF (2/22)
u' M u2 M u' //EP (only 3 edges) (5/27)

Next: L2 R2 U R2 U2 B2 R2 D' B2 L2 U2 L F2 R D U' B' D' F' D L'

Here’s another example of what I’d do:
y2 z’
B R’ E’ y U R u’ // First Block
U2 M2 R’ U R U f’ U f // Second Square
M’ U M R U R’ // Second Pair
U2 L’ U2 L U2 L F’ L’ F // CMLL
M’ U M U’ M2 U2 M’ U’ M’ u2 M’ u2 U // LSE
Any tricks I’m missing?
