Random Blindfold Cubing Discussion

[conn9]

Speffz (and variations) are uber for mbld, but Limeback's memo is still fastest corner memo for me, but sometimes fails with accuracy. Good luck!

Oh I didn't realise it was such a fast memo method. I thought it was a kind of 'beginner' method. What memo method would most pro people use for OP corners (I know pros don't use OP but oh well).

Letter pairs/images/audio loop, some probably use visual as well.

 

[Zane_C]

I was just going through my images for cards, and I got stuck on ace of spades (AS), 6 of hearts (FH) and 6 of diamonds (FD). What I realised was if I imagine myself holding a cube and visualise the cycle of the letter pair, I can instantly recall what the image is. Nothing extraordinary, I just thought it was cool how after a lot of BLD practice you can begin to recognise the letter pairs based on the cycle rather than the letters.

By the way, the forgotten images were astronaut, fish and food (how could I forget XD).

Limeback's memo is probably easiest to practice, and can be done sub5 for corner memo.
Letter for each corner sticker is probably best for audio for single bld attempts and images-letter-pairs for mbld.

most methods can be done fast with practice. Audio/Images/sentances are the best though. (for most people at least)

Alternate M2 Parity for Corners-First Execution

Standard parity for corners-first execution:
lefty R-perm after corners
U' F2 U M2 U' F2 U + lefty R-perm after edges

What I think I'll be switching to:
righty R-perm after corners (swapping UL-UB and ULF-URF)
(M' U2 M) U (T-perm) U' (M' U2 M') after edges

Would this work, or am I missing something?

That works. Standard parity seems a lot easier though. You can do any alg after corners, as long as it swaps UB and UL. I personally do a J-perm. When I'm done with edges, I do U' F2 U M2 U' F2 U, then the same J-perm.

insert alg that swaps UB and UL after corners
U' F2 U M2 U' F2 U insert alg that swaps UB and UL after edges.

At French Nats we got the following scramble:

(scramble: F2 R2 D2 L' D2 L' F2 U2 B2 R2 U2 B R D U' L2 B' R' F' U2 R2)

Would you use reorientation on it or not ? (At the comp I didn't and DNF'd in 1:13; I tried the scramble later with reorientation and got a success in 1:16, no center parity.)

 

[rubiksarlen]

Center parity?

 

[LarsN]

Just add an M to the scramble and you'll see what center parity is. That is, if you solve the cube in the orientation given by the 4 matching corners.

So I may have just decided to start learning Square-1 blindfolded once my new Square-1 gets here... (my old one is... dead.)

Dear god, shoot me now.

So I may have just decided to start learning Square-1 blindfolded once my new Square-1 gets here... (my old one is... dead.)

Let me know if I can be of assistance. If you decide to try my method, I suggest you learn how it works first by memorizing just one case to get to square (I used case EA when I was getting started), learn how to solve a scramble to that shape, and then practice solving from that shape until you can succeed with it.

Then it's a relatively easy matter to go memorize all the cases - not too hard, it just takes time. It's about the same amount of work as memorizing a 70 cube multi or so, but with the added advantage that you can take as long as you want to memorize. If you think of that as 7 ten-cube multis, it's really not all that much.

Thanks.

I can't actually find any other guides for Square-1 blind (read: i am lazy), so yeah, I'll probably be using your guide. It's weird, though, because when reading the method, it's basically all "what is this? what? i don't know AAAAAA" and then I go to bed, and the next morning I wake up, and go "why did i need any help on that at all???" Strange.

About memorising the cases: yeah, that shouldn't be too hard. I've memorised 300 digits of pi, and that wasn't that hard, and that was ages ago and I can still recall it without any problem, so it shouldn't be that hard. At least, easier than I'm making it out to be. (picture me, just staring at the list for several hours, gawking and whimpering)

This should be fun! Let's hope it gets here soon.

Read: there are no other guides. I think you only have two options: either to learn for each shape an optimal alg and a permutation of edges and corners, or to compute them during each solve (that is, speed-blind method).

 

[AbstractAlg]

motivated by DrKorbin's thoughts about sq1 bld, I've read Mike's article and was like "OMG". So many cases. 9_9

So are there any kind of commutators for sq1?
It is amazing how undeveloped sq1 area is?
For cube we probably know every algorithm, math trick, commutator, method that can be found, while sq1 has just brain-dead algs.
Has anyone done serious math research about sq1? God's number, some comms if they exist, parity research...?

 

[Mike Hughey]

Direct-solving a square-1 BLD is an interesting idea, but attacking that problem is really hard. The bandaged nature makes normal commutators for direct-solving a pretty challenging thing to work out. I wondered about it for a while, but it just made my brain hurt. So I decided to go the easy way instead.

I'm seriously regretting making a complete letter pair image list. Hurting me a lot to come up with UB-BU and other cases on the fly....

Wait, what? Why would you have to make up words on the fly if you have a letter pair list?

 

[megaminxwin]

I think he means that he's having trouble trying to think of letter pair words for his list on the fly.

 

[JonnyWhoopes]

I think he means that he's having trouble trying to think of letter pair words for his list on the fly.

Why would he have to do that? Isn't the point of a list to have all that prepared beforehand?
