Switching from M2 with new Pochmann to 2 Cycle..

[Lotsofsloths]

Currently I know M2 edges with "New Pochmann" corners, which is basically you orient them, then permute them using the J Perm.

But "New Pochmann" corners is a little bit to slow, and 3 cycle corners sounds fast and fun!

only thing about it is parity, if someone could explain M2 and 3 cycle corners parity, that would be great!

Perfect, this is exactly the methods I use! Here's how I handle a parity:

1. Finish edges and I know there is an odd parity.
2. Do F2 U' F2 M2 F2' U F2', this fixes UF and DB and the M centers AND switches UR and UL
3. Do CP. There will be two corners switched at the end.
4. Set up the two switched corners on U and figure out which permutation alg I have.
5. Execute the alg.
6. Undo the setups.

That's it!

I use DF as my buffer though(for edges)

Why not try R2? Does anyone really use R2?

IMO its too many set-up moves..

 

[Pedro]

yep, that's what M2 uses

it's just what Alex said
you can also permute other edges on the parity fix, depending on which 2 corners you have to swap

So? (message to short.)

 

[Lotsofsloths]

Ohh, sorry, thought it was a different parity alg, thanks alot!
in the next week I will start getting used to it...while learned COLL.

Wow, Alex! I never thought of dealing with parity that way, and I've never seen that algorithm before. What a clean, easy way to deal with it! I've already tried it on 5 scrambles with parity, and got 4 right, and the 5th I just messed up some other corners, but my parity fix was right. It was practically instant to learn this method instead. I think I've actually already switched to this method for dealing with parity. Thank you!

Is this method for dealing with parity common knowledge somewhere? I don't remember ever reading it anywhere.

Thanks again for showing me a better way to deal with parity!

Huh Mike? How have you been doing parity?

 

[Mike Hughey]

Huh Mike? How have you been doing parity?

Basically, not too different from how I did it with Macky's 3-cycle. Usually a T-perm followed by 2 2-cycles of edges (H perm usually), and I had to figure it out every time. I have hated parity for a long time. Now it's suddenly very easy. (Except that I still need to get used to doing all my PLLs BLD; I really am not as comfortable as I should be with all of them yet. I messed up an F perm this morning and ruined an otherwise good solve.)

It's so nice now - parity isn't a problem anymore.

Again, where did you come up with the F2 U' F2 M2 F2' U F2' algorithm? Is it on some website somewhere, or did you come up with it yourself? I see it isn't on Stefan's website, since he sets his parity fix up to work well with R2 instead.

Mike, this is the main parity fix for people using Y perm corners. It switches the 2 edges that get swapped during the y perm. There's also another fix that swaps UB and UF, if you prefer not to have Vs and Ys. This would be
M' F2 M' F2


Also, I think this parity fix I got from Erik's M2 tutorial.

Wow, I was really bad at this before. Thanks, Dan - I'm probably going to use that algorithm most of the time instead - UB and UF is even better for me in most cases. But if I use both, I can probably always avoid F perms and just use T perms instead. There are clearly a bunch of nice fixers like this - Erik's site actually has yet another one that swaps UB and UL (so I'm not sure you found it there). I probably should have read Erik's web page more carefully.

I feel about as stupid now as I did when I discovered about 6 months ago with 3x3x3 speedsolving 2-look OLL that orienting edges before orienting corners was way faster and easier than orienting corners first, then edges (I had always done it the latter way to begin with). When I switched to orienting edges first (like most people do), I shaved 2 or 3 seconds off my times almost instantly.

The added speed with handling parity is great, but even better than that is the fact that it's so much less mentally taxing to do parity solves now. This makes it much easier to do averages of 10 BLD. (I almost got one today; I needed just one more non-DNF and messed it up. It would have been my personal best, too.)

i hear you all talk about parities, but when i'm using M2 the only thing i can get is the Odd number of M2 algs. so that i need to switch the centers one more time. i do this with D'L2D M2 D'L2D. that's the only fix i use. the corners are always good(old pouchmann). i first solve the edges and then the corners. i also orient the BU, BD, and FU edge. so when i'm finished with the edges there all good.
do you get parities because your using some shortcuts or something?

 

[joey]

That is parity.

 

[martijn_cube]

yeah ok, but this is the only one i get in a solve. some people have others i guess. but is this because they don't orient all the M-layer pieces?(just use the same alg for UB and BU, etc)

 

[Stefan]

Does anyone really use R2?

I do, and maybe a handful others.

I always treated it as a more traditional parity by not solving the last edge piece, whatever it was. Then my centers were always correct, but I'd have 2 edges and 2 corners to swap. A really stupid way to do it, I know now, but previously I didn't know any better.

Does anyone really fast (say, sub-1:30) use R2?

Mondo uses it. And really, is sub1:30 *that* fast anymore

 

[Stefan]

Well, so far only 16 people have done that officially. Gosh I need to practice, soon I'll drop out of the top 100 with my lousy 3:03. Oh hey, I could still become the first sub1:30 German. Tim, Kai, Dennis and Lucas are inside 1:32-1:38.
