Blindsolving Discussion and Help

[TDM]

Oh yes, I meant images
Also, if I get a letter pair that I can't quickly think of an image for (maybe like QD or something), what should I do?

After solves, you can look up ideas for these bad images, if you can remember what they were. There are some tables/lists here, here and here, and I know I've seen one or two others around.

But during the solve... Personally, I take the first thing I can think of and trying to force that into my memo, even if it's not very good. You don't want to waste much time thinking of a better image when you can do that outside of your timed solves.

Best M2 algs for E and O?

Best M2 algs for E and O?

I'm assuming your letter scheme is Speffz (and your buffer is DF):
E: x' U L' U' M2 U L U' x (i.e. [x' U L' U' : M2])
O: x' U' R' U M2 U' R U x (i.e. [x' U' R' U: M2])

Best M2 algs for E and O?

I use
L' u' L' u M2 u' L u L
R u R u' M2 u R' u' R'
They avoid any rotations, but can be a little awkward.

What about I and S?

What about I and S?

I and S are targets in the M-slice, so they require some slightly longer algorithms that are different to the usual structure of a conjugated M2. Here are some algs you can use, note they are just inverses of each other:

I: D M' U R2 U' M U R2 U' D' M2
S: M2 D U R2 U' M' U R2 U' M D'

Remember that if S is the second target in a letter pair, you shoot to I instead, and similarly if I is the second target in a letter pair, shoot to S instead.

Addendum: If you are interested, what actually happens is that the alg for I is the commutator [D : [M', U R2 U']] with an M2 attached to the end. The comm cycles the buffer (DF) > I (FU) > helper (UB), so the piece in the buffer is successfully shot to I as expected, finally the M2 brings the helper piece back to UB from DF, and offsetting the M slice as desired, ready for the next target. You get a similar effect for S, except the comm is instead [D : [U R2 U', M']], the inverse cycle with the M2 at the front instead.

Thank you!

Hello I have a question about blindsolving: When you do a corner swap, It messes up the edges. How do you fix them?

Hello I have a question about blindsolving: When you do a corner swap, It messes up the edges. How do you fix them?

(Assuming you use OP/OP) Your Buffer is fixed so the next Corner Swap will solve them again. If you mean for when you have an Odd number of Corner Swaps in your case, do an Ra Perm

Looking for a nice comm for the cycle (UBL FDL LUF), or buffer > L > F in Speffz if you prefer that notation. Move optimal would be nice, but obviously it's speed optimal is more important here. I don't mind rotations too much as long as they aren't extreme/overly cumbersome, and I generally prefer 1 move conjugations if setups are needed (because I'm a close-minded person).

U' R [U2, R D2 R']
R cancels out in the end

I persononally would use
[U' D' R : [R D' R' , U2]]
I feel like it’s somwhat speed optimal

Maybe not exactly what you asked for, but these are regripless:
U' R U D : [ R' D' R , U2 ]
U D2 R : [ R' D R D' , B2 ]

Need some help from an advanced BLDer, How much faster are Edge Comms than M2 on average for you? about 5-7 seconds faster?

 

[CforCuber]

So I recently started learning blind and its extremely hard? Can anyone suggest methods or videos???

 

[abunickabhi]

Hi,

If you are starting out I suggest out this tutorial by J perm

An advanced tutorial is by Timothy Goh.

And a comprehensive coverup is by me, at my BLD Tutorial playlist (Shameless self-promotion)

Hope it helps to get you started!
Good luck!

 

[schapel]

J perm's tutorial is pretty lackluster as far as theory goes imo, noah arthurs' tutorial on cubing world is much better if you intend to progress beyond just learning how to blindsolve

 

[jronge94]

Coming from OP corners how long is a reasonable time to learn full 3-style for corners on UFR?
Currently know about 1/3 of the comms in about 2 weeks (might take me 10 seconds to figure out the comm I learned but meh)

 

[Cubinwitdapizza]

So I am getting into blind and I want to know what memorization method i should start with. I use Old Pochmann for edges and corners but I plan on switching to m2 eventually. If you can also give tips on what memorization method you would recommend that would be great.

Wtf is 3 style? How does blind solving even work?I tried watching a video but just got more confused.
