I'm learning advanced M2 and trying to use an extra set up to simplify tricky pieces. For BD UL I did a D' to turn BD into RD but it didn't work. Is there a rule for these set ups that I'm not aware of?
I don't know advanced M2, but if DF is still your buffer, then your D' is moving your buffer from where it should be. Maybe try something like F D' F' (or y' R D' R' y)?I'm learning advanced M2 and trying to use an extra set up to simplify tricky pieces. For BD UL I did a D' to turn BD into RD but it didn't work.

You can use B set up, just make sure you aren't moving your buffer and your 3rd piece. I use B2 U2 setup to M' "method". I am willing to add M "method" soon.

If you solve with Old Pochmann you cant do setups using B/B' or F/F'. For RB I did setup: d (or E if you like) L (to shot target to UL) and Tperm L' d'
Nope, and you can't use U moves either. This is because you can't break apart the top-right 1x1x3 block, since those pieces need to be kept exactly where they are. You're restricted to D, Dw, L and Lw.So you can't do R F and B moves?... Hmm. Ok! Thank you!
I memo visually in single BLD (and as two targets in Multi). You don't actually need to know the orientation of the buffer, since it depends on the other corners.I'm a novice 3BLD solver using M2/OP. I am trying to save some moves by untwisting corners at the end rather than solving each as two targets. How do people memorize this? I tried doing twists/flips first and just remembering them visually, but I don't like that because it twists the buffer and I have to spend time checking for twisted corners before tracing my cycles. However, when doing them at the end I keep forgetting or getting the twist wrong. Looking for good memo ideas.
Thanks TDM. I have been doing something similar, setting up the piece to UFL and doing doublesexy2 L' doublesexy'2 L. Works for me but my problem is memo. I want to do this step last so that I don't have to spend time checking for twists before I trace my cycles. But visual memo isn't working for me - by the end of the solve I have forgotten which corners and/or which directions. So I'm looking for a memo tip. I've tried adding extra letters but I tend to mix them up with corner cycles, or mix up the edge flips and corner twists. I figured someone must have worked out some good method already.I memo visually in single BLD (and as two targets in Multi).

For example, setup with [F2 R y: R U2 R' U' R U' R' L' U2 L U L' U L]. I would see that the DFL corner needs to be twisted CW. Now I know I could twist with z (left antisune) (right antisune) z'. But if you do that, you twist another corner, in this case BDL. So what I would do is put the buffer into that spot by doing B before the algorithm. So the way in which I would solve it would be:
B z L' U2 L U L' U L R U2 R' U' R U' R' z' B'.
... Hopefully that makes sense. Also, if I had multiple twisted corners, I would twist each of them individually along with the buffer.
Oh. Yeah, visual memo is hard to remember for a while, which is why I only use it for single BLD. If you're having trouble, try twisting the corners at the start of the solve, rather than at the end. You can do it in the same way but your buffer is just somewhere else. The buffer's orientation still isn't important (but the cube's orientation is!).Thanks TDM.

If I do the twists at the start, the buffer piece gets twisted, so I have to work out which sticker will end up on top before I start to trace the corner cycles. So I would need to spend time on an extra pass over the cube looking for twists. I could do that, but it's exactly what I was trying to avoid.Oh.

Twist the UBL corner, even if it's in a different place on the cube.

Got it, thanks. I would need to remember the position of the buffer piece though, and think about how to rotate to set it up, and how that rotation affects the position of the twisted corner, and how to then set up the twisted corner if it's not already adjacent to the buffer piece. Perhaps that all comes naturally to an experienced BLDer but I suspect for me the effort would massively outweigh the time taken to do an extra Y-perm to twist as two targetsTwist the UBL corner, even if it's in a different place on the cube.

Here's an example.
R' U' L D2 L2 D2 L U' D2 B2 U2 D2 R F2 L D2 L2 D2 L
Memo is FUL-LFD-DBR-UFR-BUR-UFR.
We need to twist DFR. Our buffer is in DBR. So to twist DFR and DBR, I'd do:
x2 (L' U' L U' L' U2 L) (R U R' U R U2 R') x2
You can then continue solving the same targets as memo, without tracing anything.
Now I think about it... I think in the past, when I was first starting to learn BLD, I did twist corners are two cycles. That could be better for now. I would definitely suggest coming back to twisting them using algs later on though!Got it, thanks.

I'm considering using the letter Y to indicate twists, along with the letter indicating the position of the U/D face sticker. So for your example, at the end of my corner memo, I would append YK. After solving all the cycles I would then do F2 to set up and twist it ccw with (U R U' R')2 L' (R U R' U')2 L. What do you think?
Might as well throw this one in as well..... What about 6x6+? Up to 17x17 if possible lol jk
