ZZ speedcubing method

[Cride5]

This is marginally off topic, but how fast are the fast zz-ers times at bigger cubes after reduction (if you use reduction, that is)? Do you just do EO as fast as possible, and then create line, or do you actually work out a proper EOLine? Or do you just use fridrich? I can imagine that with no/little inspection EOline is hard to do.

Its interesting you should mention bigger cubes. Doing a 4x4 or any larger even denomination, you can easily detect orientation parity right after edge pairing (during EO inspection) .... which is quite cool.

... or there's blah's method

Yes - but i don't have move count for last slot in this variation


And... Maybe zz-b has the lowest move count from all this variations.. but I have already all this algs... and.. the shortest algs for each case are very, very finger-unfriendly (likewise more from zbll)... more finger-friendly algs are just so long (both in HTM and in executing) - so few days ago I stopped learning new algs and probably i would stay with COLL+EPLL...

I have recently been gathering the algs for zz-b and maybe it is because I am gathering OH algs so I like LUR but the best LUR or LFR are normally never more then 2 moves or so more then optimal... its really not that bad for a 1LLL.

I prefer set colors too. I don't think its feasible to do color neutral in the 15s inspection like how in fridrich most people just do white cross. I first check red/orange/white and only if it is terrible will I switch to blue and green.
I started practising this method again and started gathering ZZLL algs again.

Yay, this method really is godly for OH... It scares me

Another advantage of ZZ: Much higher probability of LL skip compared with Fridrich.

First time I got it I thought it was a total fluke, but I had another one today. Has anyone else had one? Compared with Fridrich the probability of an entire LL skip should be over 8 times higher since the number of oll cases is reduced from 57 to 7. Not sure what the actual probability is, but it should be 1 / the number of ZB cases, which I believe is 493. This would make probability of a ZZ LL skip just over 0.2%

The reason this is quite significant is that if you imagine someone like Erik getting a complete LL skip, there is every chance of a sub 5 sec world record!!

Big up the ZZ

Exactly 8 times.

the number of oll cases is reduced from 57 to 7.

From 216 to 27.

Not sure what the actual probability is

1/1944

Yeah, but with Winter Variation ( http://pagesperso-orange.fr/absolutemind/f2ll-angl.htm ), you have a 1/72 chance, because there is no OLL at all
I'm currently learning all of those.

I don't think you can call that anymore than a PLL skip. You are just blurring the lines between F2L and LL, you are working to orient the corners its just in the middle of the last pair instead of right after it.

 

[ostracod]

True, WV is a transition between F2L and LL... Hence the alternative name, F2LL, as Sebastien explained... But this abbreviation could be used to describe other similar techniques, such as ZZ-b and MGLS.

It's still a REALLY nice thing to get a PLL skip when using ZZ-WV. With an average of 5 additional moves, you greatly increase the chance of having the last layer completed after F2L.

...I have to start learning CLS soon. >_<

PS: Happy 100th post for mua!

Here's a video about all the lovely ZZ variations (in celebration of my 100th post, i suppose). It should be useful for those who want to take the next step in the ZZ method after learning the basics.

Hey guys,
It seems as though I'm having some problems with EOline...I'm averaging about 45 seconds with ZZ, but at least 20 of those seconds are usually working on EOLine...I think that if I got my EOLine down to about 7 seconds (or at least 10), I could get sub-25 averages with this, which would be really nice.

Do you guys recommend doing any of the following:
-just keep practicing full solves
-Scramble, do EOLine, repeat
-take unimportant stickers off of another cube, and practice EOLine on that
(by unimportant, I mean take off all corner stickers, as well as blue/green stickers)

Other alternatives and/or help would be GREATLY appreciated

 

[byu]

To improve your EOLine:

-Learn 3OP and get REALLY fast at memorization
-Read the guide in the first post
-Scramble, do EOLine, repeat
-PRACTICE, PRACTICE, PRACTICEx100

 

[StachuK1992]

so there's no point in taking off stickers off of an old cube to help practice?

 

[byu]

You might get use of that, but really, learning 3OP to recognize bad edges almost instantly is extremely important, and it helps a lot.

 

[StachuK1992]

Where can I find a '3OP' guide?

 

[byu]

Macky's 3OP Guide

 

[StachuK1992]

haha...I actually *just* found that
Thanks...I'm guessing that I just need to learn how to identify, right?
:Here is one way to process this information quickly:
In U/D layer

1. If the piece has a U/D color, correct if this is on U/D, incorrect if on F/B/R/L.
2. Otherwise, correct if R/L color is on F/B/R/L, incorrect if on U/D.
In the middle layer

3. If the piece has a U/D color, correct if this is on F/B, incorrect if on R/L.
4. Otherwise, look at either one of the two stickers and the adjacent center. If these two colors are same or on opposite sides, correct. Otherwise, incorrect.

 

[byu]

Exactly.
I would do this:

-Scramble, start time, figure out which pieces are misoriented, stop timer, repeat

Tell me what your times are. I'm going to try this too.

 

[StachuK1992]

Alright...I'll do 5 now, 5 later:
about 16 seconds on avg., but I actually just got a 27.59 single full solve

 

[byu]

(6.66), 5.50, 5.28, 5.58, (5.16) = 5.45
It's all about practice, then it gets really easy.

 

[ostracod]

And don't forget the line component of EOLine. It can take 2 or 3 seconds to search for the line edges during a solve, if you haven't found them during inspection. Even if you have a general idea of which face they'll be on, that's useful information. And if you can, plan out your edge orienting moves so that the line (or at least half of it) is formed in the process.
