[Help Thread] Blindsolving

[Jorian Meeuse]

Not sure where I make mistakes. D2 inserts works more often than D/D’.

Maybe you just assume that undoing the setup is the same as the setup itself? Undoing a D2 is still a D2, but undoing D becomes D' and vice versa

 

[povlhp]

Maybe. But not always. Sometimes it is cube rototation. Sometimes setup, sometimes when interchange before insert. Sometimes I forget last interchange I think. Need more focus. Always works when I write it down.

I just started 3bld yesterday but I’m yet to have a success and I think I know why, but I need some help.
I think my problem is with not knowing when I’m done in memo so I keep hitting the same pieces over and over again.
So I ask these questions:
How can I know when I’m done?
What are cycles and how do you do them?
What is reviewing?
What order should you memo/execute?
Thanks for the help! Like I said, I only just started and I have 5 solves (all DNFs) but my times have been around 8 minutes

1. You know when you are done when you have finished doing all the letters you memorized, including twisting corners or flipping edges.
2. Cycles are when you go back to the buffer piece and you have to pick a new letter. Once that cycle ends, then you must go back to the original piece you started the cycle with. This video might help:

3. Reviewing is when you finished memorizing and you go back through all the letter pairs you memorized to make sure you remember them.
4. You should follow this process: Memorize Corners, Memorize Edges, Solve Edges, Solve Corners. The reason is because edge memorization is in audio memory (Saying words) and corner memorization is in visual memory (pictures). Visual memory is easier to remember but longer to do, and audio memory is the opposite.

J Perm's tutorials are very good, and he has multiple examples. You can also try memorizing and doing it sighted so you can see what you are doing wrong. It will definitely take some time, and a bit of practice, but you will get a success eventually!

Thanks so much!

Started with OP corners. Never got further than a few 2x2 BLD solves. Too boring.
Now I do sighted intuitive 3-style solves. More fun. Not doing blind yet. Still too many mistakes in execution.
No harm in doing sighted solves first to get the basics down. You can learn letters along the way.

Does anyone know of any alternate algs for the Q, I, and S targets for wings on 4BLD for the r2 method?

Does anyone know of any alternate algs for the Q, I, and S targets for wings on 4BLD for the r2 method?

Not alternative algs, but commutators that are very useful and make the handling of Q-targets very efficient.

QV: [D', r U2 r']
QX: [D, r U2 r']
QM: [l' D2 l, U']
QE: [l' D2 l, U]

You can set up all pairs of Q and R/L layer targets to one of these cases, e.g. QJ is an R' setup to QV. I also set up C/K/W to Q with l moves such that I can use these commutators more frequently.

Regarding I and S, there are also very efficient algs to handle them in combination with R/L layer targets with the same setup moves that you use for the r2 method, e.g. with J as target besides I/S: (J-setup) = U R U', (J-setup)' = U R' U'

IJ: r2 (J-setup) r' (J-setup)' r'
JI: r (J-setup) r (J-setup)' r2
SJ: r2 (J-setup) r (J-setup)' r
JS: r' (J-setup) r' (J-setup)' r2

Both of these mini alg sets take some time to get used to but they can save many moves.

I’m trying get faster at BLD solving and my solves are above 10 minutes My memo takes the most time. What should I do?

 

[Llewelys]

1) Make sure you use letter pairs
2) What takes you most time: finding the letters? coming up with words? work on that
3) At this stage, keep doing solves

I have a question for anyone who knows 3-Style:
I am trying to learn 3-Style corners, and I understand how they work, but when doing solves, do you just come up with commutators on the spot and execute them, or do you memorize commutators from a sheet?

Well, a lot of cases are very trivial, like PT (assuming UFR buffer and speffz). For most of those, you don't have to learn anything. Then there are cases like EG, which may be a little less intuitive to come up with yourself, but once you've seen the comm (it's [U R' : [U', R' D R]] btw) you probably won't forget it, because it makes sense. For this type of cases, it's important you have algs prepared, because figuring them out during exec is way too time-consuming. Then there are cases for which I treat the commutator as an algorithm, like EN = R' D R2 D' R2 U R2 D R2 D' R2 U' R', because despite them being actual commutators, making sense of them is tricky. These cases are a minority, though.

In general, I would advise you to come up with a commutator yourself for as many cases as you can, and then go through a few sheets (don't stick to just 1 sheet!!) both to get algs for cases you couldn't come up with anything good for, and to replace algs you came up with that turn out to be worse than the ones on the lists. At first, you'll find yourself having to come up with algs during solves still, simply because you won't immediately be familiar with all algs. This will fade over time though, to the point where the algs you use aren't at all what you are thinking about mid-solve.

(For one case and its inverse I actually use a ZBLL alg that isn't a commutator, namely AN and NA. It might be worth checking ZBLL sheets, but don't prioritize that.)

How to deal with cycle break and flipped edges happening at the same time?

 

[Jorian Meeuse]

How to deal with cycle break and flipped edges happening at the same time?

Can you give an example of what you mean?

 

[abunickabhi]

In MBLD, to do the long term cubes,

Is slower 4-pass better or a fast 5-pass better?
In other words, doing review and tracing 4 times in X minutes is better, or doing review and tracing in the same X minutes.

Currently I am washed up MBLDer so I 6-pass my memo, I want to 5,4,3 pass it in the future. A well practised MBLDer can 3-pass a lot of cubes.

 

[Fukuoka Kengo James]

1. For edges how should I deal with new cycles if all the alternative edge buffers on U layer are occupied (used, solved or flipped in own place)? (My edge buffer is C, and A B D are my alternative edge buffers)
2. For corners how should I deal with new cycles if my only alternative corner buffer URF is occupied (used, solved or flipped in own place)? (My corner buffer is E, and M is my only alternative corner buffer)

 

[Fukuoka Kengo James]

Like how to memo the corners on this scram

 

[Llewelys]

1. For edges how should I deal with new cycles if all the alternative edge buffers on U layer are occupied (used, solved or flipped in own place)? (My edge buffer is C, and A B D are my alternative edge buffers)
2. For corners how should I deal with new cycles if my only alternative corner buffer URF is occupied (used, solved or flipped in own place)? (My corner buffer is E, and M is my only alternative corner buffer)

Are you talking about cycle break or floating?
Your message is confusing, you're talking about "alternative buffers" as if you were floating. But someone who knows how to float wouldn't ask this question.
If you're just talking about cycle breaks, you can cycle break anywhere. Not just predetermined locations.
In the scramble you gave, corners memo is MH GW BC Q (KV)

I’ve been learning OP on and off for awhile and one of the main things I’ve had problems with is knowing how to do the setup moves, how do I learn how to do these because I know it’s better to know them intuitively

I’ve been learning OP on and off for awhile and one of the main things I’ve had problems with is knowing how to do the setup moves, how do I learn how to do these because I know it’s better to know them intuitively

If you have problems to just memorise the sequence of moves for a specific piece, you could look at the cube and the sequence to "learn" what is does: The setup transports the piece (or better "sticker") to the place, where it is then swapped with the buffer by applying the alg - while keeping the other pair in the right place (with other pair I mean: if you solve the edges, the corners should only be swapped and not taken away from their places).

Maybe you will find a system for similar pieces which would help you to learn the setups. To explain that: I don't know OP, but sometimes I do a kind of OP light, that means I use setups and only the J-perm. My buffer is URF and the target is UBR.
If I have to solve the DLB, then the setup is B2. If I have to solve DLF the first part of the setup is D to bring DLF to DLB and then the B2. You may imagine the first part of the setup for DRB and DFR. And UFL is L2 B2, and ULB is B2 D B2.
Harder: the edges (buffer is UR and target is UF). I bring them to the bottom face first, then do a setup from FD or DB (depending on the orientation). Easy: DB is M2, then DL is D' M2, FL would be L D' M2, BR starts with an E2 to bring it to FL and then L D' M2 again.
You see: I "start" with the easiest piece with the one-move-setup, then add moves before to bring the other pieces on their way.

This approach was the easiest way (for me) to let the setups become more intuitively with this OP light. So I think: if you look at the setups in OP and try to understand them, then it could be easier for your brain to learn.

By the way: I once read, that Stefan Pochmann did the same thing with only T-perm instead of J-perm until 2006. Maybe he went for the T-perm because it can be executed faster or because the T-perm is better for edges and there are 12 edges and only 8 corners. But the fact is: even a genius like him started the easy way
