Random Cubing Discussion

[TDM]

I was wondering... I'd like to finally get into OH. Now imo, for OH, ZZ is pretty awesome. I learned ZZ before, I once wanted to switch to it as a main method.
Now does it make sense to use ZZ even when I use CFOP for 2H and I'm slowly but surely getting sub 15?
I love the idea of avoiding rotation and being able to use COLL/EPLL. I'm aware that I can't avoid PLL, since I probably wouldn't learn Sune/Antisune COLL.

I use CFOP for 2H and ZZ for OH and I'm just sub-15 2H, and I think I'm not the only one who uses ZZ for OH but not 2H.
Btw, you should probably learn the diag-swap sune/antisune COLLs because you can then avoid bad PLLs (and give yourself an EPLL) and they aren't too bad to recognise.

I'm pretty sure Neil Morales does and he's second in the world for OH single.

I am mediocre speed-wise by modern standards. ~15. But do you know what gives me a little twinge of pleasure after cubing for 30+ years? That if I had a Tardis and could go back to the first championship in 1982, I could TOTALLY hand Minh Thai his ass. I watched him on TV back then, on that show, "That's Incredible" and couldn't fathom how he could be sub-25. Yeah well... 22.95 doesn't impress me anymore! Ha!!!!

Minh Thai doesn't have modern speedcubes!

(Btw, if you go back, make sure you own him with fancy fingertricks)

I could beat him on a Rubik's brand, I am certain. Fingertricks or not!

... I only just now figured out that F perms are R' U' F' (T perm) F U R. I wonder how I missed that for so long???

Y perms are made of two OLLs; swap those two and cancel some moves and you have a T perm.
And J perms are R U R' F' (T perm) F R U' R' with 8 moves cancelled.
R2 F2 R2 (R perm) R2 F2 R2 is the Gc perm too...

So conjugating T perms with R U R' F produces the same result as moving the last 4 moves of the T perm to the front? Cool!

Also,

F perm (R' U2 R' d' ..........) is R' U R (V perm) R' U' R

Yes, because those are the last 4 moves you're conjugating it by The inverse of those 4 moves then cancel themselves out at the end.
R' U2 R' U' R D' R' D R' [U D'] R2 U' R2' D R U' R = awesome F perm.
I can now do F perms from three angles! Not sure if it's worth learning it from the fourth (1x3 bar on F).

Ooh, the mirror L U2 L U L' D L D' L U' D L2 U L2 D' L' U L' is good for OH! I may switch

Too many L/U'/D moves at the start for me. I tried the front/back mirror instead:
L' U2 L' U' L D' L' D L' U D' L2 U' L2 D L U' L
But then the end has too many L/U'/D moves...

This mirror looks nicer! Imma give it a try

My main Fperm solves bar at front

M' U2 r U' x' R U2 r' U r' R2 U2 R2

fun thing: any LS+LL case can be solved with some combination of aufs, sexymoves and sledgehammers. let P = R U R' U' and Q = R' F R F' then:

Q3 U2 P' U P U P2 U = F perm
U Q P2 Q P Q' U Q2 P' Q' = 4 edge flip
[U, (P Q')2] = niklas
U P2' U2 P' U2 P U P' = pure pi
U P Q P' Q P U P U' P = R perm

Suspected this, we tried solving with this restriction at one point. Thanks for the proof.

Nice alg, but I don't think I really need to do F perms from four angles I can also do Aa/Ab/L/Ua from three though.

 

[yoshinator]

A video about OLLCP, which alg should I use?

 

[DeeDubb]

Rocking the batman PJ bottoms? Niiiice!

I use the RUR'U'F' one for OLLCP. Got 1.01 after trying like 3 times.

Am I the only person who hates the 9 move A perm? It's one of my least favorite PLLs and I might switch algs because I just can't stand it. I'd take a G perm any day over an A perm. It's short, and it's probably faster than I think, but I'm using an overly loose Zhanchi and I can't count how many times I've popped A perms.

E perms are awful. I guess I hate all the CPLLs. Unless you count H perms.
