What do you usually look for during preinspection? Most of the time there is 1x1x2 block and I use it. But I don't know what to look for where there isn't such a block.

I'm a Roux noob, but my input may be insightful. In that case, I look for an easy pair to make, while making sure my DL edge is either in place or easy to move into place.

 

[Cubenovice]

Noob too: I check if there is a 1 move left block edge (any) and look to make a pair that goes with it.

 

[arcio1]

I look for 1 move pair, too, but it takes me too much time. It isn't important at home, but at last competition (saturday) I had too use the less efficient pairs, because I didn't have time too find some nice pairs.

 

[Endgame]

there sure are other ways to build blocks, such as making bars.

 

[5BLD]

I look for an easy 1x2x2 simply and see if corresponding pair is good. If not I will go for something else. What endgame just said is (why do i feel weird saying this about endgame) a good idea too if all else fails, or if theres an easy block.

 

[PandaCuber]

i could make video about inspection. good idea.

 

[Tyjet66]

I'm having slight difficulty with CP. I know how to do it obviously, I just seem to hesitate and do a few U turns before figuring out which corners need to be switched. This happens when I don't have two solved corners facing me. Do you have any tips for figuring it out quickly, or will it just come with practice? I assume the latter.

 

[already1329]

If you see opposite colors, it's the diagonal swap case. If it's not the diagonal swap case, quickly scan L and R for matching colors. If you see matching colors, those are the solved corners. If you don't see matching colors on F, L, or R, it's on B.

I'm 3 days since starting to learn Roux -

1. What's the algorithm to orientate two lines?
2. After orientation of LSE, how do you find pieces quickly for the L and R edges, and move them there?
3. Why do my times vary so much? (from 26s to 1:07min without skips)

 

[Endgame]

I'm 3 days since starting to learn Roux -

1. What's the algorithm to orientate two lines? cycle using M'U2M'
2. After orientation of LSE, how do you find pieces quickly for the L and R edges, and move them there? after you become familiar with EO you can use lookahead while cycling to find them,
3. Why do my times vary so much? (from 26s to 1:07min without skips) F2B probably

1. With the flipped edges at UL, UR, DF, and DB, M' U2 M' U2 M U M'
2. look ahead. Also, deduce which pieces they CANNOT be in.
U2 M2 U2 M' U2 M' U M' U M U M' U M U' M2 U' M2 U' M2 U M2 U M2 U2 M U' M' U2 M' U' M'
I know that my L and R colors are Red and Orange (scrambled W/G). So the only edges with red and orange will have to be UL and UR because all other R/O edges are solved. So I can tell just by looking at F (in this example) where the edges are - UF and DF. I would do U2 M' U2 M and then finish with U' M U2 M'
3. F2B, most likely like endgame said.

1. With the flipped edges at UL, UR, DF, and DB, M' U2 M' U2 M U M'

But isn't that algorithm for a disorientated cross?

Seeing that, I think M U2 M' U2 M U M' should work.

1. No. The algorithm is correct.

2. It does not work. Your algorithm is for the cross case.

 

[Ickathu]

^^what he said. It's a similar case, and you can just do an M2 to set one up to the other, but I prefer this. There are tons of different ways I could do that EO though...

I thought I might be able to beat my CFOP average of 5 PB of 14.34 and messed up on the last solve.

I think that http://www.speedsolving.com/wiki/index.php/Fastest_Videos_for_each_Method should be updated in the Roux section. Apparently the best recorded Ao12 is over 9 seconds....

Need help with roux

I am sub-30 with cfop, but i wanted to learn roux. Should i solve the left block, then the right block, or solve them at the same time, like you would f2l for cfop?
