Blindsolving Discussion and Help

[Riley]

I'm not sure if I get what you mean. I mean, if you are an M2 off (what you mean by centers are rotated), it's FU for BD, and BD for FU. Yes just like UF and DB. However, if you want to shoot to UB, do M2. EVEN if you are an M2 off. It doesn't matter when you're shooting to UB. If you want to shoot to BU, do the F' D R' F D' M2' D F' R D' F alg. That's it. Being an M2 off only affects the UF piece and BD piece. (basically UF,FU,BD,DB stickers).

Okay thank you very much. That's exactly what I needed, and was asking.

Is it good to have a set list of what your letter pairs should be? I started a list here and was wondering if I should do that and if other BLD cubers do that.

Also where can I get something to block out the noise of my environment?

You can definitely do that, there's no downside to it. I personally didn't start with this, because it's a lot of effort, and I don't think it's any better. But eventually you can start to use more than 1 image/word/whatever for each pair, to make memo better.

You can find earmuffs at hardware stores, or earplugs probably at a pharmacy.

If i were to do Classic Pochmann corners followed by M2 edges, how can i deal with odd parity?

 

[AbstractAlg]

Solve corners, if you have done corner-swithching algorithm odd number of times, then do R-pem: R U R' F' R U2 R' U2 R' F R U R U2 R' U', then solve edges, and in the end do one more time R-perm and parity fix alg: U' F2 U M2 U' F2 U.
Complicated, but its better for audio corners.

hello, im having almost the same problem as BadMeetsEvil, with parity except in the fact that im using M2/OP instead, how do i figue this out so i can improve my %ages on my solves.

i have watched pretty much all the tutorials for M2/op that are out there but im still getting tripped up 50% of the time. thanks.

 

[AbstractAlg]

hello there, I am using M2/OP also and I first solve edges. if the M slice is twisted at the end I use U' F2 U M2 U' F2 U (*) and then continue with corners and no need to think of parity again.
If you are solving corners first, solve them all, then do an * algorithm followed by yet another R-perm.
Cheers!

 

[chardison1980]

thanks ill try that with the edges first.
but again i still get stuck with not knowing when parity happens or not, so i tend to do a lot of sited solves while writing my memo down to get a count to see if there is parity or not, by going on zanes tutorial and having and odd number of corner swaps and odd edge swaps too =parity.

 

[AbstractAlg]

the way I determine whether parity occurred or not (edges first):
- on the beginning, I think of massive green wall in front of me
- after first edge being solve that imaginary wall changes color to red
- every next edge also changes color of the wall that if it was green before edge being solved now is red, and if it was red now is green
- so wall changes colors green-red-green-red...
- after all edges, if the wall is green - parity didn't occurred and I can just go normally with corners, if the wall is red - do parity fix alg and continue with corners

My friends are using similar techniques, but they open/close their eyes on each M2 move (edge solved), or move their foot left/right, but those are just other ways to track your M slice with an ease.
Cheers! Hope this helps.

Where can I buy a blindfold from?

Variety stores often sell blindfolds.

 

[chardison1980]

wow ok seems interesting ill try that and see if it works for me, question on that note.
if counting do you start with the piece thats in the DF spot or do you start counting on the second piece that goes into the DF spot,
second part to that
do i skip over the solved buffer DF piece or count it as i come back to the buffer DF piece for each cycle?
thanks

 

[aronpm]

Start counting with the piece that's in DF, and don't count the buffer piece when you get to it.

 

[chardison1980]

well if you have a walmart or a arts and crafts store in your area, just go there and look for cloth or fabric to make one, or do what i did when i started blind solving and make one out of an old shirt that you dont use any more just fold it up more to your desired thickness so you cant see anything through the top, sides or bottom. you can use a shoe string to make a strap with.

Solve corners, if you have done corner-swithching algorithm odd number of times, then do R-pem: R U R' F' R U2 R' U2 R' F R U R U2 R' U', then solve edges, and in the end do one more time R-perm and parity fix alg: U' F2 U M2 U' F2 U.
Complicated, but its better for audio corners.

I thought of this - solve corners using setup moves + T and F permutations switching two opposite edges along with buffer at UBL. then solve edges using M2. if I have a parity, the two edges on the U layer on the M-slice are swapped. Is there a shorter sequence to fix this parity?
Yeah this is complex but better for audio as there are only 8 corners which can be memorised last and executed first.

EDIT: Not 100% sure, but I think i discovered what I wanted - M' U2 M U2 M2.
Could anyone confirm that? If so its much simpler and faster than doing the R perm, parity alg and R perm again and all. And solving corners with only T perms is really easy and effective - I think all cases can be set up with only L, R, and D moves. I do use F perms sometimes though.

Hi, I am an Italian cuber, I do 3BLD in 1:20 - 1:30 avarage:

25-30 memorizing
25-30 solve corner with commutators, not every optimal, I just started
25-30 solve edge with M2

I have two questions:
1) Do you think I improve first my memorizing, corners solve or edges solve?
2) Can I alredy start to study edge commutators or It's advisable to wait?

 

[blakedacuber]

gunna try a 3x3x2 BLD solve later using only t perms... how will i know if i have parity and how will i fix it?

 

[blakedacuber]

HIBS rubiks cube... not sure of the guys name of his channel but i liked his tutorial i think its dan sarnelli

 

[Zane_C]

1) Do you think I improve first my memorizing, corners solve or edges solve?

If you practice doing full solves, you can practice all 3 at once.
Normally corners will be faster than the edges, but I can understand that you just started using corner commutators.

2) Can I alredy start to study edge commutators or It's advisable to wait?

You will be temporarily slowed down, but in the long run you should get faster. I would recommend easing into in, so only use commutators for easy cases, otherwise use M2.

By applying simple setup moves, M2 can become the interchange for easy commutator cases.

For example, DF>RB>DL can be solved by setting RB to UB: B (M2 [U' L2 U] M2 [U' L2 U]) B'

gunna try a 3x3x2 BLD solve later using only t perms... how will i know if i have parity and how will i fix it?

If you have an odd number of T-perms to solve the edges (or solve the corners) you have parity.

In between solving the edges and corners, you must do another T-perm.
So if you solve corners first, once all the corners are solved you do a T-perm. Where as if you solve edges first, once all the edges are solved do a T-perm.

Any suggestions where I could learn blindfold solving? If anyone could point me to 1 or 2 tutorials that would be great!

My tutorial.
Or Joël's tutorial.

Zane's tutorial is very good, I learned me very fast from that video

Next question: My second 3bld success was at about 13 minutes, is that very slow for a new blindfold solver, or is it normal?
