I would replace X with Y, then go with neigh (horse)

Don't make new threads for every time you need new pairs.

BLD Numbers Allowed on Stickers?

Hey everyone!!!
So I want to do a BLD for a competition, but are writing numbers and letters on the stickers allowed, for knowing which piece is each number?
Thanks!!!

This is not allowed in competition, all stickers must have one single colour.

3d2) The colours of puzzles must be solid, with one uniform colour per face. Each colour on the puzzle must be clearly distinct from the other colours.

A9s (with the exception of the A perm) all have an "adjacent non-interchangeable" pair, so once you see that it's either an A9, cyclic shift or column. For the cancellation, there are only two possible moves, both of which break the "adjacent non-interchangeable" pair. When it's broken with a quarter turn in the correct direction, it will create a possible interchange between the moved piece and the other piece from the "pair", and a half turn will create a possible interchange between the moved piece and the third remaining piece.

I don't know a lot about BH optimal edge commutators but I think all of the shortest ones are setups to M U2 M' U2 and simple variations (mirrors, inverse) of that.

Awesome!

3-cycle case

Can someone please explain that 3-cycle ? I don't see any setup to a half slice plane.
UF-LU-BD: M'UM'UMUM'UM2
What i usually do is set it up to an easy turbo case, which is D'R2(MUM'U2MUM') R2D
I want to understand it so i can apply it to the inverse/mirror cases without learning them by hearth.

Blindfolded 2x2

Any tips for solving the 2x2 blinfolded?

 

[Randomno]

Like 3x3 corners or one looking with a normal method.

 

[Berd]

Old Pochman corners would be a good place to start.

 

[newtonbase]

Yes. I practiced OP corners on a 2x2.

I switch x with y and I have Rob YaU.

Not YU Nakajima? That makes more sense to me... What do you have for YA?

Is there a way to solve corner parity center-safely on 4bld, doing corners first?

I don't think there is, because on supercubes x-centers and corners must have matching parity.

Oh okay, thanks. I guess everyone who does corners first for big cubes does parity at the end of the solve?

Also just found out the way I've been doing corner 5bld parity has been causing me to DNF.

I only do corners first on 6x6 and 7x7, so for those I just remember the last targets of corners/midges and do them at the very end (and also have to only use commutators for the targets when centers are unsolved). For everything else I solve midges and corners last.

What were you doing wrong for corner parity? Did you change your way of doing it since your official success (which had corner-midge parity)?

I used to do centers first so it wasn't a problem, but I've switched to corners and midges first.

U' F2 U M2 U2 (Rw2 U2 F2 r2 F2 Uw2 Rw2) U F2 U does a U to the x-centers but a U' to the +-centers or something. If I save it until last it'll be fine though.

 

[SpeedCubeReview]

Using OP method, what is the algorithm for fixing the parity after corners first (Y perms) to fix the two edges? I know it's out there, but I'm getting a lot of other results in my searches.
