Blindsolving Discussion and Help

[TheOneOnTheLeft]

You can start the cycle from any unsolved piece. If VWXYZ are unsolved, and V goes to where W is, W goes to where X is, etc. (and Z goes to where V initially was), then you can, as Ollie described, start the cycle at V and solve in the order VWXYZV, but you could just as easily solve XYZVWX or ZVWXYZ, by breaking into the new cycle by shooting to X or Z respectively.

Can you please write an example blue U red F with scramble? BTW I don't use Z , i have : abcd, efgh, ijkl, mnop, qrst, uvwx

How to recognize the corners or the edges that are twisted or not????

 

[ChickenWrap]

For m2 edges, if your buffer piece is in it's spot but the m slice if off, what do you do? I have just been doing an m2 but that is obviously not correct and I often DNF when this case comes up.

 

[CyanSandwich]

You do just do an M2. The DNF must be for some other reason.

I've had it come up a lot using r2, but just in case I tested with m2 and it was fine.

Ok, thank you! Also, what do you do when your buffer edge is its spot, but it is flipped? You still break in to a new cycle, right?

This mean new cycle or some other piece is also flipped. (Buffer cannot be only flipped edge, there must be another one)

scramble: F2 L2 D' F2 R2 F2 R2 D B2 R2 U' B' D' R' F U2 L2 U L2 U' R (scramble with blue U and red F)
Starting from buffer UR, the first cycle is LD-FL. The piece in FL is the buffer. Now you choose any piece other than LD and FL to start a new cycle. The easiest is to start with UF. So the new cycle is: UF-RD-BL-BU-BR-DB-LU-FU. FU is the same piece as the start of the cycle, so the cycle ends. Notice that the orientation of the buffer is now flipped, so there is a flipped edge somewhere: it's at DF. So the last "cycle" is DF-FD.

Use this scramble: M' U2 M U2 M2

Sometimes when I am solving, I run into a case like this. What should I do? (For M2 edges, of course).

Firstly I'm assuming you've solved everything else and your last two targets are UF then UB. Normal M2 way = (U2 M' U2 M') to solve DF, then M2 to solve UB.

EDIT: Just learn all the 4/5 move cases. It's easier to be honest:

UF -> UB - U2 M' U2 M
UF -> DB - M u2 M u2
UB -> DB - M2 U2 M' U2 M'

Sorry, I should have been more specific. What I am confused about is that my buffer piece is in its correct spot, but the M slice is not solved/correct. I didn't mean at the end of a solve, just anywhere in the solve!

you break into new cycle, your UB and your UF is still supposed to be unsolved (based on the scramble you gave) so, you can choose either one

if you choose UB, the cycle will be UB(break)->UF->UB
UB: M2
UF(m slice is not off): U2 M' U2 M'
UB: M2

if you choose UF, the cycle will be UF(break)->UB->UF
UF(m slice is off): M U2 M U2
UB: M2
UF(m slice is off): M U2 M U2

3-style edges help needed

hi guys. i am very much interested in 3bld. i am now averaging around 30-40 seconds. i have finished 3-style corners and learning 3-style edges. but i can't get a sub 15 edges-only execution. that's why, tips are needed!

That's too hard to believe unless your memo is consistently sub-10...

Show us some solves with reconstructions and we can help?

Why isn't 2BLD an official event?

 

[Ollie]

Why isn't 2BLD an official event?

1. Doesn't add anything new to the current list of events.

Spoiler: 2. Top 2x2x2ers can do things like this

 

[c4cuber]

i am consistantly averaging sub 15 memo.

OK, have you tried going through all your edge algs to try and remove rotations and bad moves? And experimented with <M,U> and <R,U> stuff? If so, try drilling your edges algs until all/most of them can be executed in sub-2s?

 

[NamesYUNoLeft]

Why is execution done in the opposite order of memorization? As in memorizing corners, then edges, but solving edges first, or vice versa.

To take advantage of faster memo methods (but with shorter lifespan), like audio. In your example you only need to memorize corner for a longer time. Of course it's not mandatory to do it this way, but usually it helps and makes you a bit faster.
