[Help Thread] Roux Discussion and Help

[syzygy13]

Thank you very much for the help! Do you know where the best resources for LSE are? Also, at what point should I begin learning CMLL? As an ex-CFOP my two look is decently quick

Waffle has some very good LSE descriptions:

For example solves, I recommend you this thread:
http://www.speedsolving.com/forum/showthread.php?48028-The-Roux-quot-Example-Solve-quot-Game!
Or this database:
http://cubesolv.es/ (Search for Alexander Lau for example, he is the fastest with Roux.)

For CMLL, I average about 17s and I still use a mix of 2-Look and 1-Look. It's all a matter of preference when to start. But, some points to remember are to pick algs that fit your style and are comfortable and learn them at your own pace.

I've been practicing quite a bit and am now sub-30. Two questions:

Is it sometimes appropriate to use F2L "algorithms" for example case 14 here http://www.cubewhiz.com/f2l.php

Also, can someone help me with step 4c? Almost all the online resources say its easy, here's three mini algorithms, but do not explain recognition at all. Donovan's tutorial helped me a bit by talking about "rogue pieces" but I am still struggling to finish in 5 or less moves. Thank you

In normal solving I use Fridrich, but I've started to learn Roux for fun. In Ua, Ub PLL shall I use PLLs with M slice or can I use what I am familiar with. I mean R U combination?

If you have an Ua or Ub PLL, then do whatever you find better.
However, I have to note that during a regular Roux solve, you rarely get any (CFOP-like) PLLs.

In LSE when I solve first two in D layer, I get often PLLs like U, H or Z. I guess I should first solve R and L edges.

Edit: one more question - what CN in Roux mean. I know someone put the question last time, but I dont remeber the answer. In CFOP I solve on white/yellow.

That's what you usually don't do in Roux. Generally, higher movecount and worse case recognition.
Of course there can be some cases when it is efficient, but usually, I don't recommend to practice this. If you still prefer that way, I recommend you to use FreeF2L with OLL/PLL or CLL/ELL instead of Roux.

Practicing full CN is almost as painful as practicing full CN in ZZ - you had to know your pieces far more for efficient bluck buildings, therefore CN is harder, and you can gain better results with less effort on practicing other parts. I don't know if there are any Roux solvers who are sub15 with full CN.
Partial CN is much more useful (easier to handle), like x/y2 or y/x2 or x2/y2 color neutrality. For further explanation for those notations, see the link here:

Ok. I can see my mistake. I've made some solves today and yes - I found the way first UL/UR then last 4 edges much better. I wanna learn Roux.

And thanks for explanation of color scheme I should use.

For example, I am x2/y2 color neutral (which is less powerful than x/y2 or x2/y) with red bottom, white left. That means my block colors can be:
- red bottom, white left
- red bottom, yellow left
- orange bottom, white left
- orange bottom, yellow left

I take the advice. For me it would be:
- white bottom, blue left
- white bottom, green left
- yellow bottom, blue left
- yellow bottom, green left

And I think I will start learning CMLLs when I will be sub 40.

Keep in mind that you don't have to rush CMLL. Like I said above, I average 17-18s and I still don't know full CMLL

yes, i started them at about 23 seconds and finished them at about 17 seconds. Even so, it might be time for you finish it.

Which is exactly why I'm about to post a solve for analysis I didn't want to crowd the Example Solve Game Thread and I believe I already did that scramble.

Anyway, I will try to be as thorough as possible with comments. Any help is much appreciated. At the end I will write summarize the things I think I should work on:

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

Inspec: x2 y
FB: E2 R' u2 R' U' F2 (6) //Decent FB. Not much to say
SB: U' R' r' U R2 U2 R U2 R U' R' U' R U r' U' R (17) //Really long SB. This is one of my weak points.
CMLL: (U) R U R' U R U L' U R' U' L (12) //Nothing to say
LSE: M' U M U2 M2 U M2 (7) //Luckily short. I usually muck it up and make LSE way too long.

Things To Improve:
1) FB to SB transition
2) SB flow and lookahead + the actual construction of blocks (I wish Alex made an SB vid on Cubingworld instead of Fb )
3) Learn all CMLL's. I was lucky that the case I got here was one I know (thanks GuRoux for the reminder)

for the second block: U' R' r' U R2 U2 R U2 R U' R' U' R U r' U' R (17) you're being too fancy trying to affect the last pair when there's not much you can do. try this: U' R' r' U R2 U2 R2 U' r' U R U' R' U' R (15) or U' R' r' U R2 U2 R2 U' M' U' (M R') U' R (14).

don't worry, if it's a speedsolve, sometimes you will have slightly long sb. once you build your lookahead a little, you can play around with how you solve the square to affect the next pair more often.

Thanks. Your first suggested solution is actually something I sometimes use, but like you said, I'm overcomplicating SB to make an easy last pair.

Saw through the RB square in inspection

11.03 R2 U' F' B U' L R' B' D2 L U D2 F R' D F B2 D' R' F2 B' U' F L' B2

x2 R' M' U' M2 Rw' F // FB
R2 U R' U2 Rw' U' R // RB Square
Rw U' R' U2 Rw U R' // RF Pair
U' F R U' R' U' R U R' F' R U R' U' R' F R F' // CMLL
M U' M' // EO
U2 M U2 M // UL+UR
U' M2 U2 M2 // EP

49STM
Good solve. 4.44 tps (higher than usual)]

Another 11:
11.16
F2 B2 R' L' F2 D' B' F2 D F2 B2 D F2 U L D B2 R' F R' U B2 L' U' F2

x2 U2 R' Uw2 // LB Square
R2 F2 // LF Pair
Rw' U' Rw U' // RF Square
R U M2 U' Rw // RB Pair
U2 R U R' F' R U R' U' R' F R2 U' R' // CMLL
M' U' M' U2 M' U' M' // EO
U' M U2 M U' // UL+UR
M2 // EP

41 STM. meh slower turning than the first one.

I don't get 11's too frequently (maybe 1 in 25). Is this about normal for a 14 s average?

Good solves!

I am 14.5-ish on global average, and I have sub12 quite rarely. For example, last time I did 150 solves, and the number of sub12 times were less than 10, maybe around 7... That's close to your 1/25 rate.

Hey everyone. Lately I've been having issues with look-ahead during F2B. Do you guys have any exercises you use to practice look ahead? My main problem is transitioning to last pair of FB. FB to SB isn't as bad. Then I also have problems in SB because I resort to CFOP style blocks.

practice smooth turning as fast as you can without pauses. i guess that's pretty much how i solve the F2B in a speed solve. Because i solve SB pretty CFOP like too, FB to SB transition should be easier. All you have to find is the DR edge to start moving.
