Random Blindfold Cubing Discussion

[mark49152]

Just found the thunderclap on Lightake for 4 bucks. That's pretty amazing...I think my search may be over.

Zcube.hk $3.14 for 6+ units, but as I said, the shipping could be as much as the cubes so you need to compare that too.

Assuming that these stores get the thunderclap v2 in soon, it might actually be worth it to wait a bit.

Only MBLD? You mean where you only get one attempt per few months of practice, and one catch on a poor cube will ruin the whole attempt?

Thunderclap might not be the absolute cheapest, but it's fantastic value. Equal to an AoLong in my opinion but at a fraction of the price.

I have never done big multi attempts or owned a qiyi sail, but I've heard that the qiyi sail is pretty good (I think someone said it was like a thunderclap with cheaper plastic) and better than what a lot of people use for MBLD (Mark Boyanowski used shengshou auroras, Maskow used to use zhanchis, and many people use guanlongs).

Everyone's got their own preferences. I evaluated Guanlong, Thunderclap and Yuxin for MBLD and chose Thunderclap. I've never tried Sail, and there are other value options. Guanlong was pretty good. Yuxin was too catchy for me. If I was buying 40 instead of 10, I'd probably go for Guanlong.

No B moves in setups,

I don't think B moves is a big issue in TuRBo (I don't use TuRBo though) because you can always find a way to avoid them. setup moves can all be {R, U, L, D}

With edges first, parity can be solved just by adding UL as an extra target before the last target, or if UL is the last target, you skip it. If the last target is LU, you can flip it while flipping other edges.

You can apply the same idea for UF buffer. Add UL as an extra target before the last target and if UL is the last target you skip it. If its LU flip it. For the last OP target set the corner up to URB and do an R perm.

Are there any major disadvantages that I'm not seeing?

Nope i don't see any problems
I think if you were to use TuRBo with UB it wouldn't be very different than with UF.

I use 24 Guoguan yuexiaos and 18 Weilong Gts for mbld, I think they are a good investment for the long term as after getting above 25 or so cubes hardware starts mattering a bit more etc,

 

[Daniel Lin]

Ok so one big problem I have in 4BLD or BigBLD in general is recalling memo during execution.
In the middle of solving, I often forget letters that I'm supposed to shoot to next, even though I remember other parts of my memo. So I concentrate and think for a long time and finally remember the letters and shoot to them. Now that I've wasted so much time, I've forgotten the rest of my memo.

So an idea I have is skipping targets and executing them later in the solve
For example say the wing memo is
IBRX PADF NOSC WBMQ
say during execution we do IB and RX but we forget that PA comes next. But we do know the next next pair is DF. Instead of wasting time figuring out what comes next we just skip PA and shoot to DF NOSC WBMQ. Then at the very end, if somehow we remember PA, we shoot to those pieces using D as the buffer.

Do fast BLDers already use this? I'm guessing no, because their memory is so good they always recall stuff perfectly . I've tried using this in a couple solves, but I keep messing up

Also this probably won't work if you're bad at floating buffers. But it's not too bad if you're only skipping one or two letter pairs.

 

[CyanSandwich]

I'm not sure if any fast people do it, but it's a viable tactic.

I eliminate letters based off the rest of my memo (or whatever I can remember of my memo), leaving me with a few options for letter pairs. Then I brute force them until one of them seems right.

If it comes up I'll try it, but I'm generally counting on that not happening

Not sure if this is the appropriate thread for this question, but what do you guys all think is the best cube to get for big multi blind attempts? I just got a 7/7 [49:30] PB on my first try coming from a previous PB of 4/4 [26:50], so basically I'm getting really excited about multi blind. However I only own 7 3x3's, and I'd like to be able to eventually attempt something like 12-16 cubes. I'd really rather not make a bulk purchase of a bunch of cubes that are more than 10$ each, but I also don't want a cube that is going to perform like a guanlong or worse. I guess a guanlong would be my last resort if you guys don't think anything else sub-$10 can beat it.

Just looking to hear some opinions backed with reasoning! Thanks

I do around 21 cubes and I use a mix of guanlongs, aolong v2s, and a one or two old mains I used to have. In my experience guanlongs actually perform extremely well if you lube / tension them. I have had no problems with them. BTW, it seems like you are really starting to like bld. You say you eventually want to do 12-16 cubes because it seems really far away atm, but I guarantee that goal will just increase as you get better.

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

try this scramble. one of the worst scrambles ever.

Spoiler

4 edge cycles.
4 twisted corners.
Only two corners not permuted well, although. :fp

seriously, how do u solve this....??i am a beginner and i hardly solve at 6 minutes average both memo and execution...n my 50% attempts are always failing because of these kind of conditions...So,Can u please reply me the solution to the problem ...(btw,i use old pochman method for corners and m2 meyhod for edges)...Hoping to get reply from you fast.

also,can u give me links to sites where i can practice the hard cases of the edges only..i got no problem in corners..

go on qqtimer and under scramble type click 3x3 subsets and under that edges only

 

[achyut1]

thanks v

thanks very much bro..

check it out soon

i got

seriously had the worst scramble of my life
D2 B' D2 B2 R2 F R2 B' L2 R2 B' D B F L' U F' L' D2 R' B2
everybody should try this scramble

I got 1:26.05 but it was a DNF by 2 edges

i got 5:30 and it was a DNF by 2 swapped edges..but not so hard though.

 

[tseitsei]

Lol dat scramble

Memoed edges normally and just gave up when I took a first look at the corners...

Reminds me of Euro 2014 3BLD final scramble where we had 3 or 4 twisted corners

 

[JanW]

If you know some ZBLL/2gll alg for Pi case that doesn't move around any pieces, for example R U R2 U' R2 U' R2 U2 R2 U' R' U R U2 R' U, you can solve those corners by doing it twice. First time without setup moves, 2nd with one setup move. I've used that alg once in a bld solve with 4 twisted corners. But in that scramble it's not exactly immediately obvious in which directions you should do this.

 

[Shiv3r]

Hey, I came up with a really wonky 3BLD corners method that works really well(minimal memo). anyone like to see it? the basis of it is: orient all corners, solve the D face(by going to each U layer corner in turn and seeing where on the D layer it goes, if it is a D piece.), and then fix the U layer, and any D corners that were already in the D layer.

I don't understand this, but that doesn't matter
My way: first orientating the corners and than two at the time with buffer URF (target is DFR) and ... R2 U R2 U' R2 ... or R2 D' R2 D R2 ...
Try the algs and I think you'll see that it's quite intuitive, how to use them (which setups you need), the version with the U is for two bottom-corners and the D for a top- and a bottom corner.
Found them, when I thought, that M2 with preorientation is quite easy for me, but R2 to much to learn. I even solve two top-corners with a setup like L2 D2, because I didn't knew an A-perm at that time.
Memo is possible with numbers (only 8 corners), which was good for me, because I knew a two-digit-major-list when I started blindcubing.

But I think, this is only a good method, if you just want to solve a cube blind. To get fast you should start with no preorientation. Its harder to get the first success, but its also hard, to change your method.

EDIT: OK, parity does not work with that, there I take a J-Perm (learned that one especially for blindcubing)

So I just finished redoing my terrible corner comms (that I first learned because they were easier). I ended up replacing around 150 of the 378 comms and am going to start the process with my edge comms now. I heavily used Jay McNeil's comm list for corners and was wondering if there were any edge comm lists of that quality that exist? I know Jay picked really cool speed optimal comms and I don't want to end up learning new edge comms if it turns out there are even faster ones that exist.

So does anyone know either where Jay got / created his edge comms from, or know of any other good lists?
