Random Blindfold Cubing Discussion

[joshsailscga]

So I have a question about blindfolds in competition- does it have to be an actual blindfold, or could it be something like a rolled bandanna, as long as it completely covers the eyes? I checked the regs and there doesn't seem to be much specific about the actual blindfold. Just want to be sure so I don't have an awkward surprise at my first blind comp this weekend.

how do you guys memorize so fast i know i shouldnt expect to be world class straight away but ive only been able to solve all the edges once and that was with a 10 minute memo how was i surposed to do both corners and edges?

you have a lettering scheme, right? it's important to have one
make sure you have a good memo method (like images or audio)

if you can't keep track of the pieces, put your fingers on the edges you've memoed

I used an H perm in a 3BLD solve...

to solve corners

nice
I've used Hperms a couple times for edges

Nice. One of the scrambles at UK Championships had 4 corners solvable by H-perm U2. I saw the pattern but did not solve it that way because one piece was in my buffer and I'd have lost a few seconds thinking about it. I did swap two of them with a V-perm though, which was pretty smart by my standards

I think this is my coolest 3BLD single ever

1. 26.69 B2 R2 D2 R2 U F2 D2 B2 D F2 L D' F L2 D2 R' B2 L U2 F

[x:[U L' U', M']]
[r' U':[M, U2]]
[L:R U2 R' U2 R' F R U R U' R2 F' R U R U' R' y M' U M U M U2 M' U M' U M' U2 M2 y']

[U:[R' D R, U]]
[U, L' D2 L]
[x z:[R' U2 R, D2]]

solve before was 26.59

I'm going to relearn 3style for fun. I currently use UBL and DF, so now I'm going to learn UFR and UF and see if the comms are better. Since lots of people are debating on what the best buffer is, or if they're all the same
Expecting to finish in a month or two

EDIT:
I'm not going to learn UFR corners because I only know how to solve parity with UBL. So I'm just learning UF edges

thoughts?

 

[Daniel Lin]

thoughts?

i've actually thought of this before but I never thought of applying it to multi

I think it's better than using algs because you don't have to think about setup moves

yeh, pretty sure I'm not the first one to think of the idea. And I wanted a mbld parity method that would suit people that like the simplicity of the UB/UL swap parity for 3bld

Anyone like twists/flips?

just realized I've been doing speffz wrong for big cubes

DFr is V, not U....

it's how noah taught it in his tutorial tho

For me, DRb is V, same as DR in 3BLD. DFr would be U but it's my buffer. Is Speffz different on big cubes?

That's wrong?

 

[guysensei1]

That's wrong?

U is DFL on 3x3 though, so it's weird to have it as DFr on bigger cubes

Are we talking corners or wings? He used lower case r. Wings follow edges and U is DF on 3x3.

I'm talking about wings

just look at the diagram and you'll get it

DFr is V. The thing is, everyone who uses speffz for 3x3 and r2 for wings does speffz wrong for big cubes.

If everyone does something wrong it tends to become the new right. Like Big Ben.

Yes I see what you mean. It's not just V. My K would be L, I would be J, etc.

However, the diagram actually shows that DRf is V. DFr is grayed out. They can't both be V and which one is V depends on which wing sticker orbit we solve in. If you used UFr as a buffer then DRf would be your V. From their choice of which stickers to gray out it looks like Speffz was devised assuming this latter orbit, so we'd solve to DFl not DFr, it would be lettered U, and wings would be consistent with 3x3 edges.

For the other sticker orbit it would make more sense to rotate those corner blocks the other way so the midge at DF would be V too. Unfortunately most people learn 3BLD first, so when you graduate to big BLD your wings may or may not be consistent with 3x3 edges depending on which buffer sticker you choose.

Personally I'm sticking with following 3x3 edges, because it's clearer to me.

Just thought of something
UF and UB are F/B mirrors, right?
so UB should be just as good as UF, right?

[r' U:[M', U2]] becomes [[r U':[M, U2]]
and R2 U' R' U' R U R U R U' R becomes R2 U R U R' U' R' U' R' U R'

so if wanted adjacent buffers you could just use UB/ULB
