The ZZ "Example Solve" Game!

[Petro Leum]

This thread is similar to the "Roux Example Solve Game" thread, but focusing only on ZZ solves. in contrast to the ZZ/ZB Home Thread, detailed Theorycrafting does NOT belong here. This thread is for reflection about the solves and solutions. The main purpose is to help each other and to learn from the solves of others.

So, I give a scramble, and you write down your own ZZ solution. The solution can either be a "first try solution", which means you would do that during a regular speedsolve (or you can even do an actual speedsolve and reconstruct your solution); or you can do a ZZ style FMC (e.g., optimizing XEOLine or looking to influence Last Layer, etc). But please note what type of solution you found.

The concept here is as follows:
Every Monday and Friday a new scramble from the spoiler is used.
If i am not here on these days, feel free to take the right scramble from the spoiler and post it bold with its according number (so we dont get confused which scrambles to take next).

Note that this is not an FMC contest (although you can try ). There is no shame in a long solution, especially when you are a beginner. Moreover, the others can help you to cut down those long moves! Also, feel free to suggest other alternatives to others!

And most of all, have fun!

Good to see such a thread!

Although ZZ is not my thing, I'll give it a try.

So, my first (linear) solution:

L2 B2 U' B2 U2 B2 R2 F2 D F2 R2 F' D B L2 F D L2 R U2 R'

z2
F R' D R B D' R D' // EOLine (8)
R' U R' L U2 L' // 1x2x2 (6)
U L' U' L U2 R U R' // 1x2x2 (8)
L' R' U R // right side (4)
L U' L' U L U' L' U2 L U' L' // left side (quite long, is there a shorter way?) (11)
U l' U' L U l F' L' F // COLL (9)
U2 L2 U S U2 S' U L2 // EPLL (10)

alg.cubing.net

56 HTM.

U2 L' U R U R' (6) wouldve been 2 moves shorter for your right 1x2x2 (very different continuation though)

to prevent the indeed very long last slot case, you couldve inserted the right side slot this way:
L' R' U' R' U2 R // right side (6)
and then
U2 L U L' //Left Side (4)
that makes 10 instead of 15 moves

also, you get a very cool and easy ZBLL:

(U') R U R' U' R' F' R U2 R U2 R' (U')

Been a while since my ZZ days, but I'll give it a go. Although this completely goes against everything I believe in, because I made an oath (yes I make oaths, problem?) to only use roux. But rules were meant to be broken so whatevs.

did you notice...
U L' U L U L2 (5) for your second 1x2x2, which is actually 1 move shorter than yours? or did you plan the nice insertion you get after your solution?
Also: your Last layer can be solved with
(U) L' U R U' L U R' (U') (9)

This is the famous so-called "Niklas". Very short, very easy to recognise, you should learn it!

also, nice blockbuilding overall

after your really good blockbuilding for the 1x2x2s, it seems you kinda started being CFOP-minded :confused:

I got bored and lazy xD.

 

[cubingawsumness]

U L' U L U R2 (5) for your second 1x2x2, which is actually 1 move shorter than yours? or did you plan the nice insertion you get after your solution?

Oh interesting! I didn't notice. If I did that, the next pair could still be very easy, but maybe not as nice to execute:
U L' U L U R U R U R' U' R (12). ends up one move less for the entire right side

(U) L' U R U' L U R' (U') (9)

This is the famous so-called "Niklas". Very short, very easy to recognise, you should learn it!

Definitely should learn that. I've heard "niklas" a lot but never bothered to figure out what it was.
Thanks for the feedback!

Whoa really nice beginning. I totally wouldn't have seen to set up the line edges like that.

F L2 F' L D //EOLine (5/5)

And this is why I should be y-axis neutral... 2 bad edges vs 6.

Thanks. Sorry my 1x1x2s were so sloppy, I feel like I ruined the thread now. D:

 

[cubingawsumness]

L U' L' U L U' L' U2 L U' L' // left side (quite long, is there a shorter way?) (11)

I would do L' U2 L2 U L2' U L (7).

Thanks. Sorry my 1x1x2s were so sloppy, I feel like I ruined the thread now. D:

Please don't

Please don't

Perhaps I'll give it another go tomorrow when I'm more awake, I'll try to do the best solution I can.

L2 B2 U' B2 U2 B2 R2 F2 D F2 R2 F' D B L2 F D L2 R U2 R'

speedsolve-like solution (not an actual speedsolve, but it's the first solve I've come up with and I didn't spend a long time to think)
x' D' Lw D' Lw' U L x' D' //EOL (7/7)
U L' U' L U' L //Left 2x2x1 (6/13)
U' L U2 R U R2 U L' R U' R' //Left 3x2x1 (11/24)
U2 L U2 L' U' L //Left 3x2x1 (6/30)
U L2 D' L U2 L' D L U2 L //COLL (10/40)
U2 R2 U' R' U' R U R U R U' R U' //EPLL (13/53)

Pretty standard solve I think.

Good to see such a thread!

Although ZZ is not my thing, I'll give it a try.

So, my first (linear) solution:

L2 B2 U' B2 U2 B2 R2 F2 D F2 R2 F' D B L2 F D L2 R U2 R'

z2
F R' D R B D' R D' // EOLine (8)
R' U R' L U2 L' // 1x2x2 (6)
U L' U' L U2 R U R' // 1x2x2 (8)
L' R' U R // right side (4)
L U' L' U L U' L' U2 L U' L' // left side (quite long, is there a shorter way?) (11)
U l' U' L U l F' L' F // COLL (9)
U2 L2 U S U2 S' U L2 // EPLL (10)

56 HTM.

After your left 2x2x1 I would have done something like U' R U2 R' U' L' to finish the left block.

And this is why I should be y-axis neutral... 2 bad edges vs 6.

Doing a y' could save you up to 8 bad edges; imo it's worth learning.

U L2 D' L U2 L' D L U2 L //COLL (10/40)
U2 R2 U' R' U' R U R U R U' R U' //EPLL (13/53)

Why not do U' R2 D' R U2 R' D R U2 R for COLL? And for EPLL, R U' R U R U R' U' R' U' R2 U would save you an AUF.

U' R' U R' U' R D' R' D R' [U D'] R2 U' R2 D R2 U2 // PLL (17/59)

Bad LL.

Bad LL.

I always solve that COLL from that orientation (which is bad, since for recognition I actually look at it from the opposite side lol); it was a speedsolve-like solution.

In your solve I would have (probably) done something like
x2 // Inspection
R D2 R' D2 B u // EOLine (6/6)
L U L R2 U' R2 // F2L-1 (6/12)
U' R U2 R' U' L' U' R L2 // (9/21) F2L-3

this saves 4 moves (and leads to a different continuation) but it isn't so ergonomic

Haha, mine was also speedsolve-like, except I inserted my F2L-2 slightly differently to break apart a corner-edge pair that was a bad case. I never see ways to do two F2L blocks at once though; I'm not experienced enough with ZZ to do that. I should practise OH some more
