Like in LSE, right?

I suppose.

Hi

Just a quick question: I'm returning to 3x3x3 cubing after learning 2x2x2 solving using the Ortega method. I want learn the full Fridrich method, but I'm wondering: in what order should I learn the steps? Should I start with F2L, OLL or PLL? Thanks!

Definitely start with F2L as it takes the longest time to master. But while you're practicing that, I don't see any point in waiting to learn OLL and PLL until you're a certain time with F2L. Learn algs as you feel motivated to do so which is the best because it's harder to learn when you feel unmotivated. You can start with 2-look OLL and 2-look PLL when you feel like learning algs. Usually the last thing to learn is full OLL because of the 57 algorithms.

Learn PLL algorithms one by one and keep on practising F2L.

I actually remember that when I was learning full PLL, I usually learned a "pair" (e.g. J-a and J-b perms) and another single PLL (e.g. Y perm) in a day, so you don't necessarily have to learn them one by one if you can help it. But if you don't have that much free time, 1 a day would probably be good.

Are there any tutorials on how to predict PLL?

This is somewhat what you are looking for I think http://www.youtube.com/watch?v=YK_AfBzygI8

I heard that faz broke a WR with roux once. Is this true? Which one?

 

[Wassili]

Without knowing anything about that claim, I can already tell you that is bs.

 

[slinky773]

It was probably the world record for feliks solving a cube with roux.

He said here that he only averages 15 with Roux, so I doubt he broke any record with it.

Why does void parity happen?

To understand this, you first need to know how corner and edges on a regular 3x3 affect eachother. If you do a single U turn, you have done a 4-cycle of edges and corners. A 4-cycle takes 3 2-swaps to solve. A 3-cycle requires 2 2-swaps. So, on a regular 3x3, corners and edges will stay in an even or odd permutation together. Doing a slice move on a regular 3x3 just does 2 4-cycles of edges and corners, which will change the permutation of edges and corners, then change them back at the same time. On a void cube, there are no centers, so a slice move is only a 4-cycle of edges. Because you can affect edges permutation without the corners, you can swapy 2 edges without swapping 2 corners and vice-versa.

Thanks to my learning of LSE, I get what you're talking about.

I occasionally pop out an edge piece off of my stickerless zhanchi out of boredom. I always see hair on the core when I do so. Why on earth is hair in there???

hair gets in the cube which then wraps around the core. Try to keep the cube away from places with hair that could get in the cube

I always have hair in my cube because I have long hair. I didn't get as much hair in the cube when I stopped putting cubes in my pocket or near my head so you could try that

I'll give a bit more extensive answer;

Begin with F2L like said by YddEd until you can comfortably average 35-40 seconds. This is when you start to go into Full PLL. Learn PLL algorithms one by one and keep on practising F2L. When you've learned the Full PLL you should be down to 25-30 seconds average. Then you practise F2L. Whilst doing so find out some really bad OLL cases as you come across them and learn the OLL algorithm for them. Once you're averaging around 15-16-17 seconds you should go ahead and learn the rest of them meaning Full OLL. Then it's all advanced stuff from there on.

Thank you for this precise answer.

What mod(s) for a Weilong? I don't think it needs any, correct?

 

[TDM]

Good fingertricks for R2 U R2 U2 R' U' R U' R U' R U' R2 U2 R'? I can't find any that are good for me.

Is it possible to become a sub 5 sec solver with LBL/Fredrich for 2x2? Also I want to try different OLL ALGs where is the best place to find them?

Yeah. I just tried and did a 4.87 Ao25.
