M2 Buffer?

[fanwuq]

I'm deciding to learn M2 for edge BLD.

What buffer should I use. What are the advantages of different buffers?

Also what is the difference between FD and DF...?
I'm transferring from Orient then 3-cycle, so I think in good and bad edges.

personal preference

Doesn't really make a difference at all. I use FD, but I think most people use DF.

 

[masterofthebass]

w00t Alex uses FD also! It's so awkward being one of the few who use FD.


Anyway, there's no difference between FD and DF. I personally saw the F sticker going to B better than the D -> U. That's just my way of seeing it.

 

[fanwuq]

where do you get your preference?
You must have some sort of reason to prefer it.

Edit: masterofthebass provided a reason. Is it the only one?

 

[alexc]

@fanwuq
Dan just explained why he preferred FD.

@Dan
Yeah, go club FD!!!

Erik uses FD, right? He seemed puzzled why Stefan used DF - to Erik, FD made more sense. But I read Stefan's page first, so I got used to DF, and I found it was too challenging to switch. So I use DF.

This is way too small a sample, but so far, the FD people seem faster than the DF people.

And fanwuq, you'll get over the bit of thinking in good and bad edges pretty quickly. I now have trouble remembering how to tell the difference.

FD DF, it's your choice. The setup moves are the same. It has no real influence, IMHO.

 

[Lucas Garron]

It has no real influence, IMHO.

Not so sure about that...

DB, anyone?

 

[fanwuq]

I'm learning from Erik's site. But I'm thinking in cycles, not in solving stickers. So I couldn't figure out how to memorize it. I think I'll mess up flipping the wrong edge.
How to start a new cycle or deal with 2-cycles?

Could someone provide a sample solve (just edges) with FD as buffer?
Thanks!
I don't quite full understand this method, but I'm beginning to like it.

Does anyone here do U2 instead of R2 to swap UBL and UFR or another combo of U stickers? Works pretty well for me. I keep debating whether or not I should comit to a system or stick with visual. I did visual when I used to do 3OP but it takes a while for the information to seem relevent, which I think is the key for success.

 

[masterofthebass]

Stop thinking in cycles!!!! M2 is beautifully simple in the face that you solve 1 sticker at a time. Thinking in cycles ruins the method.

 

[fanwuq]

How would you memorize for M2?
Does it work the same way as memorizing in 3-cycle?
How would you start a new cycle?
I also don't get the parity for M2.

 

[hdskull]

Yea, I tried learning M2, and I found memorizing to be very hard since I'm way used to 3 cycle. haha. Tips would be appreciated, or a redirect link.

I use DF but maybe you can understand it a bit better with an example:
* at this point (*DB UF), you are looking at the DB sticker for your next piece. but because your centers are switched you solve it like it's going to UF. so solve like it has to go to UF, and look at DB for the next sticker to solve.
- after DL i start a new cycle. just shoot to another piece that's not solved. most of the time i try to shoot to a piece that has a large cycle after that. so that i won't have 5 short 2 cycles.
- you can also notice that at the new cycle i start with RF, and end it with FR, i think when you have that that you solved all pieces. otherwise you will end with RF again. unless you start with 1 misoriented but permuted piece, then you will end with RF i guess. But i'm not really sure about this. But this is what i noticed.
- the fix switches the centers and the LU and BU edge.
- the opposite solving of the edges only happens when you have to solve an edge of the M layer, and it's your even solved edge,(2,4,6,)
- you use the fix when you have a odd number of edges to solve.
- that's way it's usefull to memo in pairs. this way you know when you eed to solve the opposite edge, and when to use the fix.
- i like to memo with PAOP or PPAO. this way i alway will now when it's an even or an odd edge.

Lucas i am a fellow 3OP solver but if you learn with DB buffer I will also learn it!!!

[fanwuq]

For the M slice edges, you have to think about them differently from the rest of the edges, right?
The rest of the edges aren't affected by the orientation of the centers.
So do you have to keep track of the orientation of the centers the whole time?

I still don't see how to start a new cycle. For 2 cycles, is there a nice way, or do you deal with them the same way as 3OP?

 

[martijn_cube]

you don't really have to keep track of the edges. i depends on the memo method. you have to try to memo in pairs. and then you know that when you solve the (1st,3rd,5th,etc) sticker, your center is good. when you solve the (2nd,4th,6th,etc) sticker, your centers are switched.
and if you solve an DB/BD or UF/FU sticker as an (2nd,4th,6th,etc) sticker then you have to swap.
DB=> UF ---------BD => FU
UF=>DB ----------FU => BD

and for starting a new cycle, you just shoot to a sticker you haven't solved yet. most of the time you try to use U2(UB), if passible, because thats a very short 'alg'. just memo like it's one long cycle. just try my sample solve.

 

[Swordsman Kirby]

Considering I orient first with M2, of course I do DF. Now, lots of people tell me that my method sucks. Currently Rowe is the only one of those people actually faster than me officially.

 

[blah]

I didn't feel like starting a new thread on a 'personal' problem so I just posted this here, since it falls under the same topic.

Question on M2: How would you solve this? I'm new to M2, had a couple of successful open-eyed solves but now I'm stuck. I use DF as my buffer.

cycle 1: DF RF LU BL DF
cycle 2: UB UF FL BR UB
cycle 3: RU DF UR
cycle 4: DR LD RD

Damn, it's a lotta cycles.

How should I memorize the cycles? E.g. for cycle 1, should I memorize DF first or DF last? or both? 'cause sometimes it starts with DF and ends with FD (like in cycles 3 and 4), so should I memorize cycles with the starting piece at the beginning and at the end, or only at the beginning (like 3-cycle)? (I have individual letters for each sticker)

Also, when I break into a new cycle, which new cycle should I break into and why? Is there a general rule that says which new cycle you should break into for ease of solving?

Explanation together with solution appreciated.
