Well, probably I should say "for example, FDR". But here is my explanation:
The corner of this fixed target must be FDR because setup moves will be easier (2 moves for every target, for other corners there are stickers with 3 moves). So the sticker should be FDR, RDF or DFR.
Then I chose FDR because more algs have no rotations (8, while only 2 for DFR and 6 for RDF) (I'm talking about move optimal <U,R,D> or <U,L,D> algs. If you add <U,L,R>, it will be 7 for RDF).

Corner Help
So im trying to learn spheffz scheme (Sorry if i spelled that wrong) but im having trouble learning where the letters are. I mean i can go around the cube and tell what each sticker is (If i start saying the ABC's while touching the sticker and that seems inefficient because than i have to look all over to find where the piece goes and then during my execution i have to touch all the pieces to find where it belongs and that may end in a train wreck! so my question is how did you guys learn/train this scheme so you did not end in a train wreck?:confused:

Memorize the first letter of each face (A, E, I, M, Q, U) which facilitates having to navigate through the whole alphabet.
Also, you can write letters in the stickers if it helps.

If you choose your own lettering scheme, that you KNOW you're more likely to remember because it makes sense to YOU, then it requires a lot less effort to remember your scheme.
I.e. Instead of going clockwise, my letters start from the UFL sticker and go anticlockwise on the the face like this:
DC
AB
And instead of going from ULFRBD I go UFRBLD. I do this because it makes sense to me.
And if you want to go to extremes and have sticker sets going to spare you could write the letters on your cube.

I tried this with ppt, I can do corners no problems, but edges I can't. I've had a few full attempts and all fails, I guess I'll keep practicing.

Ok I will now attempt a blind solve! I will post fail or win!

I'm learning Old Pochmann for BLD and I had a question about breaking into a new cycle.
I use a lettering scheme, and D and E are on the same edge piece. If D was already within my first cycling of pieces, I can't break into a new cycle by switching my buffer with E, right?

Nope, once you solve D, E is technically solved too. Break into a completely new edge piece.

I am getting back into bld. My memo is like a minute when it used to be 30 seconds. Any tips for getting back the hang of bld.
Ollie

Just do solves, it might be a while and require a bit of patience but your success rate and normal speed will return. I can't think of a specific 'technique' for getting back into BLD.

What are the advantages/disadvantages of fixed Ulb buffer or floating buffer on U for 4BLD centres? Would it be better to learn floating buffer from the start in order to be more comfortable after some time with it, rather than finding later that I want to switch and it being harder?

Pros:
- You can win up to 3 targets (1.5 algorithms).
Cons:
- You can win only if there are no upper centers on upper face (if there are, you'll win less), and only if each chain has even length.
- 3 centers (or even less) is little.
- More complex memorization.
- No speed-optimized algs.
As a compromise, you can use speed-optimized algs for fixed buffer, and when you chain ends, you turn U making next center as a buffer. And don't forget to adjust upper layer after the centers.

Okay, thanks, I'll work on that then.

I am trying to learn commutators (and BH in general).
I am following this tutorial: http://www.speedsolving.com/forum/showthread.php?12268-BH-Tutorial
I have problem with first exercise: EXERCISE A. Earlier in this section, we worked on the commutator (URB LFU LUB) with the interchange move of B. Do this commutator again, but use L as the interchange.
My solution:
A = R' B' R B
B = L'
Then perform B A B' A' commutator.
My solution solves the case, but it is 10 moves long. As I understand optimal solution should have only 8 moves.
Where I am doing mistake? What is optimal 8 moves solution to this case? (with L as interchange)

The interchange can be done first: [L',U R U'] = L' U R U' L U R' U'

Thank you TDM for response.
So I have another one: how to determine if I should do Interchange first or second when doing commutator?

in m2 what do u do if the buffer is flipped
TDM

New cycle. If you get your buffer piece in the buffer position, flipped or not, always new cycle.
