I've spent a whole day trying to learn them, but was unsuccessful. Oliver told me to learn some BH algs then the rest is intuitive. I know intuitive commutators for 4BLD centers, but can't figure out how to do them for corners.

Yes, I agree with tseitsei. Daniel and I never intended anyone to just learn the algs on the BH website, and it is my sincerest hope that nobody does that ever. The list is there as a reference so that you can see how we execute a particular case that you're working on. It is our intention that you will learn the theory of how the commutators work, much in the same way a CFOP solver would learn to solve F2L intuitively or a Roux solver would learn patterns for building the second block.

I don't know why it is so hard but it just doesn't click with me. I understand them, but should I just watch Noah's 3-cycle tutorial over and over until iI understand them, should I watch Daniel Sheppard's 4BLD corner video or what? Is there something that I'm not quite getting? Sorry for being a complete newb, but this will bother me until I understand it.

Try learning from Dan's 4BLD centers video first. He explains how commutators work in terms of the action spot, insertions and interchanges. But a lot of center algs can be applied to corners as well (for example, try doing r U2 r' d' r U2 r' d on a 4x4x4 and then R U2 R' D' R U2 R' D and see how similar they are).

Thanks Ollie. I will try my best to to understand them. Now, if you'll excuse me, I have to re-watch a video.
I have a question: Should i learn OP corners with ULB or URB buffer? I know ULB buffer will be easier but will URB buffer transit better into BH/freestyle? I don't want to relearn everything when switching to more advanced methods so i'll go for URB if it's worth the effort.

Either one is fine. You can do 3-style/commutators from both buffers just fine...

I have the same problem as you, except I'm making the switch from ULB to UBR because the tutorial I use has UBR as the buffer, and the list of algs on the BH website use UBR as the buffer. The only thing I need to do is recognise when I reach my new buffer, which won't be terribly difficult to do once I get used to it.
Now for my question: how do you flip corners/edges in comms?

What's with all this fuss over which (corner) buffer to use? I don't think it makes much difference. Your time would be better spent working on something else.
That said, one of the things that's on my list of silly things to research (very low priority, but there) is to try to optimise every possible 3-cycle case and some parity systems to try to see if there's any 'best' choice of buffer to use.

Erm...I'm switching buffer because it'll make learning BH/3-style/comms a whole bunch easier because that's what buffer my resources use. My 'time would be better spent working on' learning them quickly and solidly rather than flipping the cycles to be the same with my resources. Now this is only useful when I'm starting out, but...
...but when I 'try to optimise every possible 3-cycle case,' I'll be able to refer to the list on the BH website with the same buffer. And that's nice.
Ah OK. I didn't realise that; thanks.

Ok. First of all: You can choose either ubl or ubr but switching the buffer has no advantage that I can see right now Because:
Learning comms shouldn't be like learning algs. You should learn how commutators actually work and once you figure that out you can (and you should!) come up with your own style of solving each corner cycle. For example I could tell you how to solve any cycle from ANY BUFFER in a matter of few seconds since I know how comms actually work

Yes, you're right, but I use URB for the purpose of easy learning and easy reference. I'm beginning to understand commutators now, and I practice whatever cycle with whatever buffer, but still with URB as my main buffer. Also, what do you think would be a better buffer and for what reasons?

Maybe ULB for more RU heavy algs?

Parity alg set: DF-DB UBL-x
Turns out these are pretty nice, way better than the DF-UB set I made previously. This was done fairly quickly so there may be mistakes/obvious improvements.
If doing this on big cubes, you might want an alg for wing swap on D, here's how I would do it on 5x5 (best time is 1.74 on 5x5, 1.50 on 4x4):
(r' 3l') U2 R' F2 (r2 R2') F2 R U2 (r 3l)
It's similar to the standard alg but modified to be on D, and I've changed the exec a little which I think helps, I can do it faster this way anyway

I can't stand the wait for Maskow's multi attempts to be up on Cubecomps... we're about 55 minutes of the way through his first attempt.

Any idea what he's attempting?

Last I heard, he planned to attempt 46 cubes.
