New weird 2x2x2 idea

[Kenneth]

In some scrambles you find a block of two pices oriented in one face and two of the opposite colour in the opposite face...

AUF and hold the cube so you got the two bars at Rdd and Ldd, this gives a pseudo oriented first layer, then orient the last four in the same manner. The rest is Guimond separation (not all cases are represented) and PBL for the end solve.

Maybe not a method to use every time but an option for advanced Ortega/Guimond solvers when a scramble like that comes up.

The only hard part is to learn to recognise the orientations but after some practice it will become easy.

Hey Kenneth.

I suggested a similar method to that guy that has a site about the different 2x2 methods but he didn't like it. The steps were:

Step 1: Solve DFL and DBL, or any 2 adjacent pieces on the L-layer.
Step 2: Solve any set of 2 adjacent pieces on DFR and DBR
Step 3: NMCMLL. Then the final move would be an R/R'/R2 (or L/L'/L2 of course) adjustment.

Another way of describing it would be to say that it is like solving non-matching blocks in Roux (that's how I had the idea, I was using NM Roux at the time). It is about a 12 or 13 move average (if you use 2x2x2 specific sequences for Step 3). Maybe the guy didn't understand what I meant. If you want an example, I'll give one.

Recognition for step 3 would be horrible, but if the first bar is already done it will give a very short and fast solution.

 

[JTW2007]

Yeah, I do this sometimes. The recognition isn't that bad actually.

It's not horrible but it's not great either.

Do you really? How do you recognize the corners? I only know of a few ways to do it and the easiest/fastest way I've ever seen is Gilles Roux's idea shown on the NMCMLL chart I made for him, but it's still bad. It takes about 1.5 times longer to recognize NMCMLL compared to CLL (3 things to look for in NMCMLL versus 2 in CLL/COLL/etc).

Here is an example:

Scramble: D2 B2 F L' B L' R' U' L D L' B' L B2 R' U2 B' F L R F2 D2 B' F U'

Solution:

Bar 1: R2 z'x'
Bar 2: U'R U
NMCMLL: FRUR'U'F' U'R

But, the focus should be on Kenneth's ideas, not mine. Sorry Kenneth.

I may be confused on what method you're talking about. I would align the bars (using, say, orange and red) so that the bottom face has two bars, one orange, one red. Then treat O and R as the same color while you orient the top face, then use a guimond case to solve both faces, then permute. Is that the same method described here?

I may be the one that was confused, I believe what you described is actually what Kenneth was talking about. So my idea isn't really like his, only the "bar" idea is there. Whoops.

 

[EmersonHerrmann]

I tried using that, it allows a lot of possibilities

 

[Henrik]

To me some of this sounds like OFOTA, but that might just be me.

simplified ofota, it splits the ofota step 1 into two parts.

 

[Kenneth]

Athefre, I first tried to do CLL but recognition is horrible and using that you need to have two compleate bars, not just oriented, scrambles like that are really unusual.

so is this what you are talking about kenneth?
