Random Blindfold Cubing Discussion

I'm considering learning Square-1 BLD, I can do corners and edges, but I do not know how cubeshape would work. Does anyone have any knowlage on how to do so that it would be easy to memo CS, corners and edges? One looking the CS would be hard, especially as I am not great at square-1.

I have practiced edges and have got a 1:59.93 success.

Lol sorry forgot. MBLD was awful, I only got 1/5, and everything else was off by no more than 4 pieces, and 4BLD was pretty good. I managed not to look at my cheat sheet for any of the parity algs or any of the "wierd" corner cases. I am about to do a scramble where I write down my memo, and see how that works out. I will post the result after I do it. ;)

Also, your signature,

http://hughey.cubing.net/Square1BLD/index.html I've been using this for general sq1 solving too!

But it's a lot of effort. Focus on your 4BLD success :)

As Cale S said, swapping UL and UB in memo is a technique to deal with parity. I hardwired it to the program because I consider it to be the simplest (and coincidentally fastest) way to deal with parity. Do you use something else?

From learning with your site scrambld.cubing.net, I always swap UL and UB now(for parity). I think it is super easy to do and saves on moves.
 
I don't use the parity trick that seems to be popular these day in 3BLD, where you pretend UL and UB are swapped to leave an OP case at the end (might switch eventually though).

I had a thought yesterday though which I haven't seen mentioned before: why not do it for bigcube wings too? Corner parity on 4BLD? Pretend UBr/ULb and UBl/ULf are swapped, and now you don't need to do corner parity, just an OP alg at the end. Means you would only need at most one 'parity alg' for when you have wing parity (of course, technically Y-perm is also a parity alg, but it's far better than a pure corner 2-cycle). Also works on 5x5.

I memo corners last for 4BLD and 5BLD so I'd have to change that to make this useful, but it's worth considering.

Has anyone ever thorght of teaching begginers old Pochman as a first method? It only needs 3 algs and it's easy to understand

I think Zane's tutorial teaches OP/OP.

I've been thinking lately, that there are some advantages to starting people off with OP/OP instead of M2/OP, like Noah's tutorial does. I've seen way too many people get confused by M2 and I think it might be better to let people skip all that confusion by starting them off with OP edges. That way, your first BLD solve will be as simple and as straightforward as possible, and it will lead to a lot less frustration. It would also be a lot better for those who just want to get a BLD solve, but don't intend to get into it seriously.

As well as that, I feel that starting off with M2 might not actually save that much time in the end. OP edges is virtually the same as OP corners, and many people will be able to understand it minutes after learning OP corners. I feel that people might also be able to learn M2 more easily once they've had a bit of experience with BLD. That way, they're not still wrangling with the concepts of cycle breaks, memo and all the other BLD concepts while simultaneously learning M2. You could probably even skip "normal" M2 and go straight to advanced M2 (which again, I think is easier than normal M2) and skip all the M slice targets nonsense.

I thought OP/OP was the normal first method. But I agree about advanced M2 being easier than normal M2.

Well, Noah's tutorial has become the "go to" BLD tutorial that most people recommend to beginners now. At least on reddit, whenever people ask for a BLD tutorial, they are pointed to Noah's one.

I suppose I'm not saying that Noah's tutorial is bad, or that it teaches the wrong things. It's just that whenever people say they plan to learn OP/OP, a load of people always come along and tell them that they must learn M2 instead. I think OP/OP is an equally valid option, and it has it's advantages.
 
When I have taught people bld I always teach advanced M2/OP. OP/OP is just unnecessarily simplified and move heavy and as said before advanced M2 is actually easier to understand than normal M2...
 
I'm following this OP vs. M2 vs. Advanced M2 discussion with interest. I'm casually learning some BLD starting with OP corners on 2x2 and will progress to learn centers after that.

I'd like to see a beginners tutorial with advanced M2.

I'm curious, what do you teach them for parity?
Click to expand...

I have never done a tutorial in my life :D So I probably suck at it... But the basic idea is just doing M2 but if you have M-slice target you must setup so that you have no M-slice targets (except UB) anymore (preferably simultaneously putting 1 target to UB but that's just a bonus).

So let's say you have targets LU and BU for example
1. you notice that 1 of them is on the M-slice.
you need to setup it so that neither of the targets is on the M-slice (except UB is allowed).
2. You can do B setup move and now have LU BL targets that can be easily solved with M2 "normally"
3.Then just inverse setup move. So do B'
ALTERNATIVE
1. If you are a little more advanced and smarter you can do setups L' B' to set BU to BR and LU to UB
2. Now that's even easier to solve with "normal" M2.

And when you get even more advanced you can setup other cases to be better too (not only cases with M-slice targets). For example setup move U for case UL LD or stuff like that.
And after that you can learn to use FU and BD as replacements for "shooting positions" instead of UB.

It's just as easy to learn than normal M2 and you understand what you are doing instead of using mindless algorithms. That makes it easier to improve your method and gradually move to 3-style edges...

But for parity I teach them to:
1. Memo corners first.
2. If odd number of targets you have parity and need to memo UB and UL as swapped.
3. execute edges as you memoed them
4. execute corners normally with OP and parity will automatically be solved because of odd number of corner targets...

TL: DR instead of teaching them algs for M-slice targets I teach them to setup targets away from M-slice

Haha, I wasn't necessarily asking you to make one [emoji14]. I was just saying I'd like to see one made. Nice explanation though, I might link it to people in the future.

Cool that you teach them that method for parity. I had though that it might be too hard for beginners, but I suppose there isn't really another way that doesn't require learning additional algs.

No I meant as a sighted method haha.

Oh, wow. I completely missed your point.

I guess setup moves would be the only thing that would be hard to teach. I'd say it would be slow as hell though, and not very nice to transition into CFOP.

There was a guy who learned 3OP as his first method, and did his first ever Rubik's cube solve blindfolded. Would be kinda cool to have more people attempt this and get it on film.

I was thinking lately on whether the switch to UF as buffer for edges would be better in terms of commutators for that buffer being better. I did see somewhere on the forums a topic on the top BLDers and their buffers. A bit of background info about me:
Average right now is 35-40s(have 3 sub 30 singles. Yes, call me crazy for even contemplating switching). Average memo is 12-13.

Current buffers now are DF and UBL. Method is predominantly 3-style with little M2 now and then.

I have never used TurBo edges or UF buffer before but I can pretty easily figure out comms for it.

So, should I switch? Why/why not?
I also wanted to know how people with UF,UBL as buffers solve parity.
