One answer BLD question thread blind

[EricReese]

Is there some site which can give me a setup so I can practice my pure commutators? I want to practice my pure commutators but I don't know how I can.

[MovingOnUp]

Memo one of the unsolved corner as the target position, then memo its target, then memo the displaced pieces target. Its basically breaking into a new cycle

Okay I think I get this going to try it out right now thanks

Hey I use Pochman/M2 because I am a total beginner at blinfold solves and I was wondering when you memorize the corners using the method shown in Eric Limeback's tutorial what do you do if the corner cycle type thing you are memorizing has the actual corner that goes in the place that you are using to cycle the corners around. not sure if I made sense there? If not do this scramble on a solved cube (yes I know it is a long one) (R U' R' U' R U R' F' R U R' U' R' F R) D (R U' R' U' R U R' F' R U R' U' R' F R) D' (R U' R' U' R U R' F' R U R' U' R' F R) Now I know you would have to randomly place any other corner in there that is already unsolved but when memorizing I am not sure how to memorize this I just have no clue my mind can't follow I guess? somebody help me otherwise I am going to just make a thread?

Setup - L U' R U L' D
(R U' R' U' R U R' F' R U R' U' R' F R)
Undo Setup - D' L U' R' U L'

@Eric I want one too! I really need pure comms practice.

Question: bh corners (URB LFD RFD) why doesnt F' [U', B2 D2 B2] F work? Im doing the insertion and interchange correctly, right? Can someone tell me the exact conditions for an interchange and the insertion? Im confused. Also, for (URB RFU DLB), why not L2 F' L2 B2 L2 F L2 B2? Whats the error?

Also, how to recognise columns?

Can all columns be either an A9 or cyclic shift?

Happy cubing, tjen

lol thanks I'm still not sure I understand how to do this though. Going to try working it out on paper first before I try actual thing again

I moved one of the unsolved corners to the buffer position without disturbing your UB and UL edges. To do this, you just need one corner in the R layer ( which it is already), so I did L U' to bring the buffer piece into the R layer. Then I did an R move to replace the buffer piece with your unsolved corner. I then undid my setup moves for this step by doing U L' which places your unsolved corner where your buffer piece was. Then I did a D move to place the other unsolved corner to your normal destination position. I did Y-perm to swap the unsolved corner ( which is now where your normal buffer would be ) to the other unsolved corner at RFD, and UB/UL edges are also swapped. Essentially you are replacing your buffer piece with an unsolved corner, and then solving normally, then replacing the buffer piece to its original position. The undo-setup is self explanatory, I would assume. Hope that helps!

@DYGH.Tjen:
Your insertations are wrong. Insertations work like this: you 'open' a layer, 'insert' something in it and then 'close' it again so that only that one piece has changed in that layer. These 'open' and 'close' turns cannot be double turns because in that case you would change more than one piece with this operation.
All columns can be set up into an A9 or a cyclic shift.
You should read byu's BH corner tutorial: http://www.speedsolving.com/forum/sh...68-BH-Tutorial

Oh I see what you're trying to do there. Break it down: L2 F' L2 supposedly inserts RFU into DLB, B2 is the interchange. Now the problem is what I wrote: Your insertation doesn't only effect DLB but also the BR and BUL pieces, that's why it doesn't work. You'll find that in this case there's no correct 3-move insertation.There's one with 5 moves though - you can either use that, or set up to an A9 or cyclic shift.

About the program to practice commutators, just add something like this:

printMethod((char)(Math.random()*26 +65) + (char)(Math.random()*26+65));
I love one line code. Then again, making the class and main method along with a pause and while loop would take more. If you arent a program, look up how to run a .java program in commmand prompt, open a notepad, type the code that follows after the instructions, save it as Name.java, and run.

public class Name
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.println(((char)(Math.random()*26 +65) + (char)(Math.random()*26+65) + "\n");
System.out.println(input.next().toLowerCase().contains("y")?"Great":"Aww");
}
}

This question is asked so often that I think this forum would benefit greatly if someone would write up a stickied post explaining how to break into new cycles. Any takers?

[minime12358]

I agree so much. I was actually thinking of this the other day. We need to basically have the first post edited with info like:

How do I do blind? Learn Old Pochman

What happens when the buffer is solved? Break into a new cycle (swap with a random unsolved piece)

What is the fastest method? BH incorperated into Freestyle

What is the fastest memo style? Visual

How do I know which piece to go in blind? Create a letter scheme, one letter for each sticker of a corner (A-X) and one for each sticker of an edge (A-X).

How should I start memorizing for the first time? Possibly make words to represent one or two letters, or look at (Wiki page)

How do I solve a (Insert Large Cube here) blind? -Link-

Where is the BH edge tutorial: Link

Where is the BH corner tutorial: Link

What is the world record? 30.90 set by Alejandro (I forget the last name)

Where is a good tutorial for Old Pochman? (Possibly bad mephisto's tutorial, etc)

What do you do if you do an odd number of M2s in the M2 method? Do parity (Insert Parity algorithm here)

Theres a basic template, I dont have time right now to insert the links, but we do need to put this on the front, as these questions are asked a lot.
