Blindsolving Discussion and Help

[aronpm]

Hi

For 4x4 centers, (I'm using speffz blindlettering scheme), is there a good way to solve ACV, AUB and AVB using comms? And if you type out the algs for me, can you please explain why is it done that way? I seem to have trouble doing stuff that involves the buffer, something else in the U layer and the D face. Thanks!

P.S. try and explain in a way like how Daniel explains stuff thanks

ACV: Lw' U2 l U r2 U' l' U r2 U Lw
Same type of thing as a columns corner case. Lw' sets up to a 9 move commutator.

AUB: z2 U l2 U' r2 U l2 U' r2 z2
I don't know how to explain that one. It's pretty simple. It's like Niklas but with half turns instead of quarter turns.

AVB: mirror of AUB

 

[DrKorbin]

AUB: l2 D r2 D' l2 D r2 D'.
Explanation: Ubl and Dfl are interchangable with move l2. (D r2 D') will put Ubr center to Dfl place so nothing more is changed on the l-slice.

Having trouble with Old Pochmann corners

i am having issues with old pochmann corners. when the buffer peice becomes solved it just messes up the rest of my memo.

what i am asking is there a good way around this? or is there a more efficient method?

You've either solved the corners or you need to break into a new cycle. If you've shot to every unsolved piece, you've solved the corners. If not, break into a new cycle

L2 U B2 R2 B2 R2 U' F2 U2 R2 B2 R' U R D F2 R D R U

Y perm
R Y perm R'
D F' Y perm F D'
F' D R Y perm R' D' F
D2 R Y perm R' D2
*new cycle*
R2 Y perm R2 (any piece that isn't solved already)
R D' F' Y perm F D R'
R2 Y perm R2

What is the T-perm algorithm which swaps AND flips the two midges on a 5x5x5? In other words, the 5x5x5 equivalent of the x' R2 U' R' U R' x F' U' F R U R' U'.

Had a couple of parity cases like this recently, where knowing the alg would've probably got me a PB.

i would like to start learning BLD, i think its very fascinating. and i was told a nice beginner method was Old Pochmann/M2, but i found that Old Pochmann/M2 is very confusing to me. particularly the "setup moves" you need to do.so i was wondering, if there a different beginner's method i should try?

There really isn't any other beginner method that allows for an easy transition to a better method than Old Pochman. I'd recommend Zane's Tutorial.

Just learned old pochmann bld, so bear with me here: if my buffer piece is already solved, do I shoot it out to a random piece and consider it a cycle break?

Yes, that's correct. When you get back to the piece you chose you either break into a new cycle (if there is more unsolved pieces) or you are done.

That's correct, unless you've shot to every other piece, in which, you're done. If you use a letter scheme that goes alphabetical, I suggest going to the piece closest to the start of the alphabet. (ex: If you get your buffer, you should shoot to A. If A is solved, you should shoot to the next closest letter, B, etc.) I do this (with M2) because it helps having a system to choose from, instead of picking a piece randomly that you might forget. Hope I helped.

My question:

Is this the UWR for M2/OP? Or maybe UWR on video? http://www.youtube.com/watch?v=InC5yvbr4Dk&list=UU_1e_mktuZTKYAwkNPvmbzw&index=1&feature=plcp

(Cornelius Dieckmann, 44.19. He said he got 43.55 later, in the description, which is more of what I'm asking about)

Hello again, speedsolving community. (=

I haven't really been cubing for a long time, but I thought I might get into it a bit over the summer, specifically blindfold solving.
I already knew how to solve BLD, but I only just learned pretty much right before quitting, and used Old Pochmann for both corners and edges with sentences for memo (with a bit of visual for corners). I recently learned M2 for edges, and thought OP for corners shouldn't be too rough (though I might eventually switch to BH, but only once I can memo decently). However, I really dislike sentences for memo, and even already came up with a letter pair list for Roman Rooms which seemed like an interesting way to do it. However, I'm finding my memo to take long (like, real long, 8 minutes long). I only just made the list (over the past 2-3 days), so I wasn't expecting to speed up quite yet. My question is twofold:
- Would it be wiser of me to simply study the list for some time and only really start practising once I'm confident I really know what's on it, or practice, practice, practice until I'm more comfortable with it that way?
- What would be a good memorisation method for corners, to complement M2/Roman Rooms for edges? Is Roman Rooms on corners any good, or should I just keep visual/tapping?

What are your memo and solve orders? It seems that the majority of Pochman corners + M2 edges solvers memo edges then corners, and then solve corners then edges. This allows the corner memo to be much less "permanent" since you don't have to remember it for very long.

I previously used groups of 5 people for memo, three for edges and two for corners, with each person receiving 4 letters (pieces). Now that my memo has sped up significantly, I have found that it is easier to drop the two people from the corners memo and just use basic sentence for those pieces. I still use the full groups of five for multi, however, since that requires the memo to stick around longer.

The point I'm trying to get across is that if you memo corners last but solve them first, roman rooms may be a little overkill. It would no doubt work, but it would be kind of like killing a spider with a grenade.


In regards to your 8 minute memo:
I was VERY slow for a long time. (8:00 - 15:00) but when I began averages 6:00 or so, it seems that they dropped by a couple minutes almost instantly. What I noticed about my times is that they began sort of "avalanche" as I became quicker. The faster your memo, the less intense it has to be since you don't have to remember it for so long... which means you spend less time on it, which means it becomes faster... etc, etc, etc. It's pretty circular.

Thanks for the quick response.

Sorry, I totally forgot to mention that. I, indeed, memo edges then corners and solve corners first, for the reason you stated. That is why I used visual for corners (it's just that I find myself sometimes getting confused over it >.>). Maybe I should switch that with basic sentences or something of the sort.
Are there any BH/M2 users? What do they do? (Since I may switch eventually, but that's thinking into the future and isn't a desperate question)

Ah, I see. I assume you mean that just for the corners, though? Roman Rooms for edges outside of MBLD is still okay then?
If not visual or Roman Rooms, what might be wise to use for corners? Sentences? Audio?

Thanks. Feels good to know I don't just suck.
(Well, I do, but there's hope)

Audio for corners, when memorizing corners last and solving first, works very well, because you can do it very, very fast, and just execute it right after you memorize them.

 

[Phlippieskezer]

Heh, kind of stupid of me to just ask that and not actually try it. Well, I just did and it works very well. I think I'll use Roman Rooms/Audio for edges/corners, then. Thanks, Carson and Riley.
My edge memo still needs A LOT of work, though. Guess I ought to start studying that letter pair list...

 

[Czery]

I use color pairs to memorize my edges. It works nicely but the biggest problem I have is forgetting.

I can never do more than 3 consecutive solves because I get my memo confused with previous solves.

Does anyone have any remedies for this?

This always used to happened to me, but I found the best way to to just deal with it. Just really try to do more, eventually, you should develop a wall against that. It worked for me. If it still isn't working, you can do one solve, take a break for five minutes, and then do another. Repeat. After it seems the memo isn't getting confused, try taking a break for 4 1/2 minutes, and see what happens. Eventually, you can lower the break time. Hope this helped.

I use M2 edges OP corners for my bld and when I solve i virtually don't have many pauses. Yet my times still aren't sub 2. What am i doing wrong?

How fast is your memorization? If I just time execution then I can get around 1:25 using M2/OP. That calls for a pretty speedy memo. Maybe try learning some BH commutator stuff for corners (and edges too, but corners are slow using only Y perms). You can also (and you might be already doing this) start using J perms too, to cut down on movecount.
