How to solve corner orientation with sune and antisune
==================================================

This guide is made for begginers that want to solve OCLL without learning the 7 OCLLs just yet. Also this guide aims at solving the OCLLs using at most one sune, AUF, and one sune/antisune.

So for solving all 7 orientations you will need to learn 2 algs first:

If you have 3 wrong corners:

The Sune

Put the solved corner on the front left position and apply the alg:
R U R' U R U2 R'

The Anti-sune

Put the solved corner on the back right position and apply the alg:
R U2 R' U' R U' R'

EDIT: alternatively, you can solve as if it was the sune and you will be left with an U2 + sune

So if you have 3 wrong corners you know how to solve.

==================================================

Now if you don't have exactly 3 wrong corners, you will reduce the case to have 3 wrong corners. This is how you do it:

If you have 4 wrong corners:

Put a wrong corner pointing left on the front left position and do a sune.
Now you will have a sune to solve.

==================================================
If you have 2 wrong corners:

Put a wrong corner pointing front on the front left position and do a sune.
Now you will have an anti-sune to solve.

==================================================

I hope this guide can help.

Please comment!

That's actually a really interesting way of looking at those cases.

I've been trying to come up with some sort of scheme to help my girlfriend remember where to start her sunes for beginner CO. So this might come in handy... thanks!

That is actually pretty useful!

I used to teach something like this:

Sune (R U R' U R U2 R') will bring up the stickers of FUR, RUB and BUL.
If you have only one yellow sticker on top, then it is sune or anti-sune (trivial case).
If you have less or more yellow stickers (non-trivial case), then search for an AUF, and see what would a sune do (which yellows come up, and which ones disappear to the side). Out of the 4 possible AUFs, there is (at least) one in which a sune would cause an exactly-one-yellow-sticker-on-up case (which is of course a sune or anti-sune case).

For example, let's see your last image: the yellow stickers are FUL, UFR, RUB and UBL. A sune would leave FUL (yellow sticker remains on F), turns the UFR (the F color would go up, yellow goes to R side), turns the RUB (R sticker goes up, which is yellow in this case), and turns BUL (the B sticker would go up, and the yellow sticker disappears). So, overall, we would have only one yellow sticker on up: this is the right AUF, and do a sune. Right after, do a sune or anti-sune (anti-sune in this case).

But I have to admit, this is a much easier way for begginers! Thank you for sharing. :tu

Thanks for you feedback.

good explanation! i wish i had has that when i had my rubiks cube workshop at school. was pretty hard to teach stuff like that w/o material

thanks. I successfully taught my dad this method, he got it really well.

Actually, this is an upgrade for the orientation portion my Roux 2 algorithm CMLL video. The recognition is a bit better than the way I did it.

Let's call it a usefull reminder for new cubers.


But actually this is very old stuff

Take out the "2 wrong corners" case, and do the same as you would for 4 corners.

To make it even simpler, take out the anti-Sune case.
This is how I teach it:

• 1 corner solved: make sure the ULF sticker is yellow
• Otherwise: make sure the LUF sticker is yellow
• Do a Sune (and start over)

It might take longer, but they will never get stuck.
For this kind of approach, it doesn't really get simpler than that.

 

[DeeDubb]

This is how I described it. I went through all the cases.

I might improve to a more simple description, but I think this isn't too bad. It was sort of just a flowchart from one to the next.

The title of this guide is "how to use sune and antisune to solve OCLL". Not "how to use sune several times to solve OCLL".

The title of this guide is "how to use sune and antisune to solve OCLL". Not "how to use sune several times to solve OCLL".

You're using them multiple times, though?

The first post states that "This guide is made for begginers who are learning to solve the cube and don't know OCLL yet."
For true beginners, it is my experience-backed observation that you should aim to keep it as simple as possible.

(It is not true that "you will need to learn 2 algs". You should figure out what exactly the purpose of this guide is, and make sure the steps and claims match that.)

Edit: Oh. It appears that your objective is to solve OCLL using at most two [anti-]Sunes. You should state this very clearly, and perhaps add a short remark on tradeoffs (number of cases/algs to memorize vs. number of algs you need to execute in a normal solve). I also suggest changing the "who are learning to solve the cube" phrase. Presumably this is for beginners who *have learned to solve the cube*, and are now taking small steps to improve. (This is definitely a good step for that.)

I wanted to make a easy and efficient guide. And 2 algs are not that bad.

EDIT: I changed the guide description.

2 algs are definitely not that bad.

However, 1 works nearly as well. I just did quick calculation for the descriptions in your and my post.
Yours averages 1.63 algs/solve, while mine averages 2.22.

I think doing an extra alg half the time is still pretty efficient.

For instructing beginners, I'd argue that making the description simpler (namely: using one alg and a single way to handle non-Sune cases) is worth the tradeoff. If they get to the point where two algs for a single step are not that bad, pretty soon 7 will not be that bad either.

 

[Deleted member 36445]

I agree.

 

[Lucas Garron]

EDIT: I changed the guide description.

Thanks, that definitely makes it more clear.

You could possibly make it even more clear with something like: "solving any OCLL using at most two algs: one sune, AUF, and then one sune/antisune".
It might seem subtle, but these details matter – especially if you're targeting beginners.

Ok. Next step would be doing a guide showing how to solve the 57 OLLs using sune/antisune variations.

Maybe. However, here's the approach that comes to my mind when you mention that:

- one of F U R U' R' F' or F R U R' U' F', followed by
- Sune or anti-Sune

If you allow mirrors, you can get most OLLs (that have two edges flipped) directly into a Sune or anti-Sune. YOu don't even need to memorize anything.

Before spending a lot of time working on a system, think about what you're really trying to do. (Unless you just want a fun exercise.)

Why not use sune,antisune, fat sune and fat antisune? Along with their mirrors. Even less memorizing.
