Blindsolving Discussion and Help

To the 4BLD solvers:
In 4BLD do you always go about the center targets in the same order or do you pick for easier memo or comms?
I find myself doing the latter occasionally...

I go almost always in the same order. In some cases I make exceptions, normally if I would get a lot of cycles, so I avoid them and make one or two long ones.
Don't really care about memo, cause I use Letter-Pairs, so every pair is nearly as easy to remember as others. And I also don't think about comms. I just memorize it, I only start thinking of comms during execution.

I pick a different centre target to extend the cycle if the first one I'd normally pick makes the cycle end with an even number of pieces (i.e. 2 swap will be left). On the other hand, if the cycle is getting too long (and hence I'd like to begin a new cycle soon with another U centre), then I might force the cycle to end at a convenient point.

THX for your feedback.
My typical reason for picking not the "next-in-line" target is when I see that the piece next to it gives a straightforward 8 mover like [r U2 r', d] instead of first having to apply a set up move to one face. (I try not pick targets zig-zag all over the face though)
The other case is when all U centers are solved, I will then store my buffer piece a the "end" of a face.

I'm looking for commutators to 3OP, is there any site with list of algs?

I asume you want a list of commutators for every case of 3OP permutation. I have not seen a website with a complete list specificly for 3OP users. You should look at the BH and 3style lists because they have all of the 3OP comms.

For corners, I use these.They are non-optimal but still intuitive and good.The list only has half of the comms because the others are the inverse of the listed algs.note that this is 1/9 of the BH cases. Don't learn these as cases because they can be simplified into a few basic ideas.

For edges,If you use 3OP for edges the best advice I can give is to switch to a better method.

I made them all myself a while ago before BH was 'released' but I think they may be lost to the ether :/

Searching BH pages is easy, there are a bunch of different lists on here - Riffz' is my favourite so far.

I'm struggling comms for oblique centers. I've read this post, but still I have a question. In T-centers, for Ub>Uf>Df I use [U2, m d2 m'], a "half-slice" trick. But this doesn't work for obliques, because there is no m-move. So how can I solve Ubbr>Uffl>Dffr or Ubbr>Ullb>any center on D?

I'm trying something more simple than BH.

That's a nice trick - I should start doing that. I don't do very many of those tricks, which is why obliques are not much harder than the more normal center pieces for me. For that one I setup with (SiGN notation) 2f R2, then the obvious 8-move commutator, then undo the setup. If you're talking about two obliques that are not on opposite sides (front-back or left-right) of the same face, though, then you can do those the same way you would do them with X or + centers.

Sorry, I would give actual algs, but I don't have a big cube in front of me and I rarely use SiGN notation, so I easily get confused by it. If you don't get it from this description, say so and I'll work it out and give actual algs.

If someone has a good, easily understandable shorter answer for that case, I'd love to hear it. But 12 moves isn't all that bad, and that's as bad as it ever gets.

Hey everyone.

So I was just wondering why nobody uses a DB buffer.

Thanks,

[Rpotts]

Because you can't see either of the stickers when you are holding the cube "normally."

Aaa, no, I got it. Thank you very much!

Yes, but the set of algs you're looking for is a subset of BH. Just look for the corners-oriented BH cases in BH lists to find different speed-optimised algs.

Um..... you only have to look at it once. And chances are, you'll have to look at the piece anyway during your memo.

May be It would involve more B move, which is not the most finger friendly? Am I right?

Jakube uses UB.

 

[DrKorbin]

Maybe the reason is that many bld solvers come to speed-optimal 3-cycles either from TuRBo or from M2, that's why UF and DF are the most popular.

Well no beginner method is popular with a B buffer.

 

[rubiksarlen]

How does everyone do M2 (in BLD, not normal solving)? For me, I always do r2 R2, which although faster compared to doing M2 with ring/middle finger, result in a lot of turn fails (making my dnfs look really ugly) .

I notice everyone can do it with their ring/middle finger with ease, I on the other hand find it slow and hard with all the regripping.

 

[drewsopchak]

Left Ring, Right Ring.

 

[Rpotts]

I do right ring, right middle. Same as I do it in normal solving.

You may also want to try R' M' r - which is usually performed like R' -> use right middle or ring to pull the M' on UB then do r simultaneously.
