Random Blindfold Cubing Discussion

[amostay2004]

Pretty cool, might explore more of those when I feel like it. At the moment I just do it TuRBo style though (x L' U' L U M' U' L' U l x)

 

[riffz]

Actually, there seem to be very few good cases for DF buffer using that technique. Am sad.

For the reflection I'd do the reflection of Amos's alg, but for that case I'd do M' [U' L' U, M'] M = M' U' L' U M' U' L U M2 (not any more, that alg is schmexy)

 

[Sakarie]

Moveoptimal supersafe U-perm?

u [L', u M2 u'] u'

 

[cmhardw]

Moveoptimal supersafe U-perm?

u [L', u M2 u'] u'

Nope

Cool alg though!

All you people who use M2 in BLD:

In BLD (as opposed to SpeedSolving) Do you tend to:
A) flick the M-Slice with your ring-finger, (As in M2')
B) flick the M-Slice with your index-finger,
C) Finger-trick it with ring-and-index fingers
D) Do (r2 R'2)
E) Do (R2 r'2)
Or what?

I normally do 2 flicks of my ring finger. But out of curiosity, I started messing about with R2r'2 / r2R'2. In a limited set of trials performing (M2 U)*12 I found I was only slightly slower doing the latter method.

Sighted, I sometimes try to flick the M slice really hard and make it rotate a half turn, but it's ridiculous to do that blindfolded.

Left-ring-finger M', right-ring-finger M'; I'm much quicker that way than any other way I've tried.

On big cubes, though, I use a double left-index-finger pull from the top at BU. It just feels safer that way (especially on 7x7x7).

Oh, and for OH BLD, I do a thumb push at FU, done twice for M2. It's really pretty fast and very secure for OH, and you can keep a death grip on the cube while doing it - especially good for while juggling with the other hand.

Looks like the move-optimal supercube-friendly U perms (I checked UF -> UR -> UL) are:
[F2 U: [[R2: F2], U2]] = F2 U R2 F2 R2 U2 R2 F2 R2 U F2 (11f*)
[F2 U: [[L2: F2], U2]] = F2 U L2 F2 L2 U2 L2 F2 L2 U F2 (11f*)
[R: [U', [F: E']]] = R U' F E' F' U F E F' R' (12q*, 10s*, 10sq*)
[L: [U, F]] [R': [F', U']] = L U F U' F' L' R' F' U' F U R (12q*)
[L': [[F': E], U]] = L' F' E F U F' E' F U' L (12q*, 10s*, 10sq*)

(There are a lot more 10s*... I won't write them all out.)

Okey, is there an 8 move STM?

And is there a better one that works for wings and 5x5 middle edges?

I do my M2s like Erik does for U perms in his PLL vid. I kind of do a slight R' to bring my right ring finger to UB and then pull it all the way through as an M2'.

(R' M' r), but I've considered switching to (L M' l'). Just never took the time to switch...

 

[RyanReese09]

Just 2 M' with my middle finger. (Left middle finger, I do M slice turns with it).

 

[Marcell]

R' r M' (using the middle finger for M'.)

If you care about supercube optimal then 10 is optimal (as shown by Michael). If you're not worried about supercube safe then you can do 7STM with
UF->UR->UL : F2 U' M' U2 M U' F2
If you're thinking supercube safe then you can go with the options that Michael listed above.

For wings and 5x5x5 central edges I do:

Wings UFr -> URb -> ULf :
F' R' u' R U2 R' u R U2 F

Central edges UF -> UR -> UL:
F' R' E R U2 R' E' R U2 F

 

[Xishem]

Left ring M', left middle M', just like speedsolving.

Can someone please help me with the Old Pochmann Method?

Whenever I solve the edges, at least one of the top edges isn't oriented correctly.

What am I doing wrong?! (I use T-perm and J-perms)

What is the best possible commutator for this,

http://i.imgur.com/1a5odl.jpg" title="Hosted by imgur.com

I'm doing U R2 (Li' U2 Li E' Li' U2 Li E) R2 U'

[Where 'i' With the L means inner layer L (sorry I'm not so familiar with the notation)]

So I know this is quite bad and there is surely a better commutator with less moves to solve that.Thanks

I would do F2 as the set up move: F2 [r U r'] u [r U' r'] u' F2

Lower case letter means inner layer slice.

Cool,you did that F2 to make white and red center pieces interchangeable right,thanks

I was being so dumb,I restricted myself to not moving the action spot,So I did a U so that the insertion can be made and R2 so that the interchange can be made,how stupid of me.

Thanks Zane
