[Help Thread] 2 look discussion - OLL and PLL

[zeus]

I am the same as you. i use 2look OLL and full PLL (except that N!!....N=A+T ) but i get good times. i even avg 14 by 2 look. so it all depends on your own but the general advice is: LEARN THEM ALL....

 

[Cubic]

You are all so fast. It makes me feel inadequate!

I looked at ZZ, but didn't really understand the tutorial. So for now I will stick with CFOP which I am comfortable with.

 

[PandaCuber]

~Stuff~... I am comfortable with.

Good choice.

I'm sure some people can get sub20 even. I know you've heard this a ton, but the important part is F2L.

I can confirm this, I've been sub 20 for quite a while now and I still haven't gotten to learning the g perms. F2L is definitely a huge part.

Just realised I've made a mistake in the title.. It should read 2-look OLL - do I need full PLL?

That would make more sense, yes.

Im almost done learning full pll its taking forever though i still havent learned the G-perms yet and its so annoying when i get a G-perm and i cant solve it

Thank you, I was wondering how to do this.

Keep practicing with 2LPLL until you get like sub 25 or so. (Yes, practice a lot).
First learn the J's, A's, U's, H, Z, Y and T. They are the easiest to learn. Then learn the other algs.

I've learned J(b) and T. They were VERY easy . Quite quick to execute, too. As for getting to sub 25... that is going to take me a L O N G time!

2-look PLL question

Hi. I have a question about 2-look PLL. Apologies if it has been asked before but I have googled and searched the forum and haven't found anything that answers my question.

Anyway, here goes...

I am going to learn 1L-PLL but I figured I have got to learn all the algs, so I may as well learn the ones which will let me do 2L-PLL first.

So I have looked at a few sites and for 1L-PLL there are 4 algs for switching edges and 3 for switching corners. So far so good.

However, there seem to be a number of PLL cases which I can't solve in 2 looks using these 7 algs, for example Na and Nb.

So my question is this: is it possible to solve all 21 cases, in 2 looks, using the 7 algs, or have I misunderstood what 2 look PLL means.

As Na and Nb are not 'symmetrical' I can see any way of solving them using those 7 algs, no matter how many looks I use (and certainly not in 2).

/that should say look not loop

Yeah 7 algs (or even 6 algs actually...) is enough to 2-look all the PLL cases. And as you said you need 3 (or 2) for corners and 4 for edges.

For example Na-Perm could be solved by first doing

Any diagonal corner swap PLL you choose to use for 2-look PLL (so you can choose either Y-perm, E-perm or V-perm. I would recommend Y-perm)

Okay so let's say you choose Y-perm and apply it first.
Now you are left with AUF and U-perm only.

Thanks for the reply! I'm glad to hear it is actually possible to do all cases with the 7 (or 6!) algs.

I got a bit confused as I have found several sites that are supposed to show how to do 2L-PLL, but they only show you 2 algs, and say you might have to do them more than once each (which didn;t make a lot of sense to me).

Check out BadMehPhistos 2 look PLL videos.

You can solve any PLL with only 2-algs but you have to usually do them more than once. So that's not really 2-look PLL...

Yeah, that's what I figured.

It's a bit confusing when you're starting out and you've got people using the same terms for different things.

I have been looking at Paradox Cubings youtube site and found some useful stuff there, but his beginners 2 look PLL video is just 2 algs that you might have to do twice each.

That's not much different than beginners method.

you can do 2 look PLL using 6 algorithims actually but it is not reccomended for speedcubing, R' F R' B B R F' R' B B R F R U' and R' F R' B B R F' R' B B R F R U' Ui R' F R' B B R F' R' B B R F R U' and M2 U M2 U2 M2 U M2 and M2 U M2 U M U2 M2 U2 M U2 and F2 U Ri L F2 L' R U F2 and F2 U' Ri L F2 L' R U' F2 or even 4 but that involves just knowing cases and where you will have to do it again after the first time

yes but there is generally a pattern for more than once that you can remember you only need 3 algorihtims but you have to add moves in the middle and do it twice

I learned 2L-OLL yesterday, and I'm learning the 7 algs for 2L-PLL today, but even with the algs on the screen in front of me, I am having trouble knowing which ones to do to get it solved in 2 looks.

Not for all cases, but some of them are quite tricky. Do you have any tips at all?

First concentrate for corners only and ignore edges. Look for 2 same colored corner stickers on one side for easy recognition (again IGNORE those edge stickers). If you don't have 2 of the same colored corner stickers you have diagonal swap (do Y-perm). If you find 2 same colored stickers you have adjacent swap. So you put those stickers to the left side and do T-perm. Now you are only left with edge case which should be easy to recognize (Ua (3-cycle), Ub (another 3-cycle), H (all edges opposite) or Z (all edges adjacent))

Thanks for the reply.

Are Y-perm and T-perm required for 2-look PLL? Cubewhiz says you just need Ua, Ub, H, Z Aa, Ab and E.

Is that right, or is it better to learn other algs.

(I am going to try to learn all 21, but just trying to get the most necessary ones learned first).

you need Ua, Ub, H and Z. Don't learn Aa, Ab and E. Learn either Aa, Ab or T, and then learn Y. I would suggest learning T because although it's longest, it makes learning Y (which is even longer) much easier.
