Are there any tutorial/guide on leor method? Especially on efficient EOLine. I'm using ZZ as my main method so doing EO itself is fine, but I find doing it in the MIDDLE of the solve rather than in the beginning pretty tricky.

I quit cubing like 6 years ago, and now I'm getting back into it, starting with the 2x2x2. I'm trying to remember my old PBL algs, and there is one that is eluding me. For the PBL case with 1 bar, I had learned two algorithms for that--one for when the bar is on top, and one for when the bar is on bottom. I've been searching through various alg lists, but I can't seem to find the one that I used when the bar is on bottom.

The muscle memory came back to me momentarily, and I was able to perform the alg 1 time, but then I lost it again. It started with an L, and then there was a D2 somewhere after that, and that is all I can remember of it. Does anyone know this alg??

So I just solved the 4x4 yay! (I didn't learn it I solved it)
And it got me thinking, if I use my solved 4x4 as a 2x2 (by only twisting 2 pieces at a time) what would happen? Well obviously nothing good, you might accidentally only turn 1 piece then you have to go back. The cube is bigger and corner-cutting is no nice. So I tried this "event" and here are my results (I didn't practice this I only did it once)

PB: 13.30
Ao5: 18.21
14.45
13.30 (11.30, +2)
21.34
24.26
18.92
---------
My ACTUAL 2x2
PB: 6.07
Ao5 12.39

Try it yourself! What are your results? Maybe even try using a 6x6 as a 2x2, or an 8x8. Or a freakin 9x9 as a 3x3 (BIIIIIIIG OOF) Didn't try any of those as my biggest nxn is a 4x4.

Note: NOT ACTUALLY RECOMMENDING THIS AS A WCA EVENT THIS IS JUST A MISTAKE

ive doe that efore but its kinda dumb just sayin
Yup, might even be the dumbest of dumb or smart of stupid, dumb weird of method events. (What did I just say?) I didn't really mean it to be taken super seriously.

But wtf 9x9 acting as a 3x3 or oof 16x16 actin as 4x4

I presume you can solve FB , RB and LL. So EODFDB is quite easy. It's based off the fact that r* U/U' r* flips four edges (as does M* U/U' M*). So orientate your centres after FB (have your D colour on either U or D), then solve 4 bad edges at a time. If you have 2, you can do either some F U F' type thing, exactly like ZZ, or you can do r U R U' r' (look at how that works) or something similar. 6 and 8 are just the same as ZZ. So for 6, you could do 2 then 4, 4 then 2, 3 then 4 and for 8, 4 then 4. Then solve DFDB without messing up EO.

Just came across this video on the WCA youtube channel and really thought it was great, and thought it would be good to share. Also, I am hoping that they do more soon, even though almost all of that is on Github but still for people that don't want to read/go through everything, the video is a great addition.

Did the community survey they discuss there ever happen? If so, I think I somehow missed it.
Someone correct me if I am wrong, but from what I have read on GitHub, the survey's are something that they are working on still, and will be released within the next few months (maybe once they get the WCA forums up and running).

Okay, that would feel better. It's just that, from the video, it sounded like they intended to get it out sometime in the next couple of weeks from when the meeting was held, and that video is over 2 months old.

So basically, yesterday I looked on the web for something that explains why parity is impossible and needs to be fixed by means not part of the cube movegroup. It came up with this seriously advanced paper, mostly filled with random equations and stuff, etc. I clicked out, and found Ryan Heise’s page on Parity, which lead me to the laws of the cube, and now I can reason why I have to twist a corner and am not cheating to a non cuber. Just in case they don’t give up after I say ’it involves university level advanced mathematical group theory’ (which it doesn’t really).
