Random Blindfold Cubing Discussion

[riffz]

I'm watched this many times. Still amazes me.

He uses images along a route. 2 cards per image. I'm pretty sure for memorizing digits he does a single image per 4 digits >_> (That's 10,000 images...)

I also agree with a. this time, there is a similar feeling but yes this seems much more adrenalinic (?)
although this doesnt seem to have as SD as rubiks cube blindfolded has at all. This guy probably gets sub 25 most of the time

Many fast people at speed cards use a PAO system of 1 person, action and object for each card. This amounts to 18 PAO images, which are visualized throughout a memory palace (roman room, journey, etc.)

It is true - it looks like he looks at the time and is quite satisfied, but not surprised at all. I suspect the main reason for the satisfaction was a feeling that the memorization seemed secure. He probably got some nicely compatible images that made it easy to remember.

I've heard Ben Pridemore describe his memosystem somewhere, and he uses like a consonant for every 2-Ace, and a vocal sound för every pair of suites, and based on this he have predestined images, thats 13*13*16=2704 images, and then he uses memorywalks. But I don't know how this guy does it.

If you want to find out just how good you are with twisted corners, try this scramble I just got from qqtimer.

L' U' B' R2 U D' R' F2 D2 B' R2 U2 D' R' D' U2 B2 D2 U2 L2 U2 D2 L' F L'

 

[Brest]

Here is a scramble for all to try:

D2 R2 D2 U2 F2 D' F U2 B R' D R B U L2 B' U F D'

 

[Stefan]

Here is a scramble for all to try:

D2 R2 D2 U2 F2 D' F U2 B R' D R B U L2 B' U F D'

DNF (2:36.71)
Stupid little mistake, should've been solved in the same time.

What scramble is that, or what's special about it?

 

[Mike Hughey]

I can't say exactly why, but that did seem easier than usual for some unknown reason. 1:11.88.

4:36.98 DNF 2 flipped edges. Just seemed like a normal scramble.

D2 R2 D2 U2 F2 D' F U2 B R' D R B U L2 B' U F D'

I tried this when you first posted it and got DNF(31.xx) (I think .44, not sure) off by a 1 missed move somewhere near the end of edges. Seemed like a normal scramble.

 

[Brest]

Yuhui Xu's 30.58 WR scramble.

Thank you for everyone who made an attempt!

Would a cube stickered like this be useful for practicing (supercube) big BLD? Would it be considered valid? I'm imagining, as an improvement, a cube with no numbers, just labeled with the color plus the Speffz letter.

 

[Rpotts]

Anyone find this as a good alternative to the standard Y perm for OP corners?

R' F R2 U' R' U' R U R' F' R U R' U' (14)

One move shorter HTM and doesn't end in R, which I have sometimes confused with the R orbit setups that end in R. It's about the same speed for me, hadn't specifically seen it listed for BLD. It's just another Y perm without the first/last F turns.

Yes, I prefer that for BLD, and I prefer that Y perm in general, I feel it flows a lot better.

It's nice.

Even though it doesn't drop much time (if any) in comparison to the standard Y-perm, the U' at the end prevents any cancellation mistakes with undoing the setup.

 

[Rpotts]

That's the main reason I see for switching. Sucks when you get the "O wait, did I cancel that, or do I need to.." *R'..R...R2...R2'* Nothing worse than accidentally thinking during a blindsolve.

 

[qqwref]

Yeah, it seems really nice. If I did Y-perm corners I'd definitely switch to it (but I've done 3OP since the first day).
