5x5 BLD guide needed!

[trying-to-speedcube...]

Well, i think U2 is the best.
My accuracy is pretty good with U2.
If you have any questions, especially about breaking into new cycles on the U-Face, feel free to ask, cause this is quiet tricky.

Greetings...Dennis

I never break into new cycles in the U-face. If I have a U-sticker in my buffer position, I just pretend it's unsolved and shoot it into another place in the U-face. I do this by 3-cycling. My buffer is Ubr, suppose I want to shoot to Ubl, I'd do: r' u r U r' u' r U r' u r U2 r' u' r U2. (I suppose you could call this breaking into new cycles, but I don't see it like that.)

If anyone has a better alg for this (I have been thinking about some modified A-perm or something like that), please post it here, because what I use seems to be pretty long and therefore slow.

EDIT: r2 b2 r F r' b2 r F' r

I accidentally didn't include this in my tutorial. I'll update it as soon as possible.

can someone say me if tehre is a method for the centers of a 5x5 which uses U2 for the pieces which are not part of the "cross" of the center?

Isn't it the same as 4x4 centers, except you don't get to choose the orientation of the puzzle?

Yeah, you solve the X-centers in the same way on 4x4 and 5x5.

Yes you do.

Yes you do.

Well, I mean on 4x4, there are no fixed centers. If a big group of greens was completed on the left side on 4x4, you could just set that to green. Although I guess you could do it on the 5x5 by using center switching algs.

For 5x5 BLD I use U2 for 4 center, but for the other 4? For the pieces which are part of the "cross" of the center?

 

[aronpm]

Use commutators. While you're doing that, learn commutators or x-centers too

Many of us do exactly that.

You could use m2, doing setups to Ub. Or simply U2.

sorry but I cannt understand, you show me some example set-up and anti set-up for the following centers

I think we're not thinking of the same thing. I don't know what you're referring to with those four centers on the F face. What would you like me to do with them?

What I was referring to was that when starting a 5x5x5 BLD solve I will look around the cube for large blocks of one color. To use the example from the quote before me, let's imagine I find a large block of green. I will spin the cube so that the green block is on the front face, regardless of whether the centralmost center on that face is green or not. I then figure out which of the four remaining z spins of the cube are even parity for the centralmost centers, and I use the one that gives me the most "other centers" solved.

I then memorize the cube as normal. However, just before donning the blindfold I look at the cycles of the centralmost centers and see how they have to cycle to return to their original locations. After putting on the blindfold I execute that cycle using 4 move commutators that turn only the m, e, or s layers first before solving anything else.

Hope that helps,
Chris

Chris

Maybe you've right, I use U2 for 4x4 Blind, as far as I know its an easy way to solve the center. the set up are all intuitive
Now, I can use U2 for 5x5 bld, but only for 4 center, I'd liike to find a way as easy as U2 to do the other 4 center, for example, this center

Different peple say that solving 4x4 bld is very difficult, for me no
(I had DNF in the race, but that's another story)
now I'm interested in learning how to solve the 5x5 BLD, I will not be fast, I just want to be able to solve

You don't have to put the "e" or "m" when telling which sticker you mean, since there are only one Fu.

Well, if you use Ul as buffer, and shoot to Ur, I guess it would be

sus' U2 su's' (You would definitely prefer doing y/y')
s'ds U2 s'd's
re2r' U2 re2r'
er'e'r U2 r'ere'

I think those are correct.

After putting on the blindfold I execute that cycle using 4 move commutators that turn only the m, e, or s layers first before solving anything else.

(sorry for the quick sidetrack)
I noticed that Chester does that as well. But I got so accustomed to memorizing corners last and solving first that I actually memorize a single image to know what the centers fix is (memorizing it at the beginning), and then I solve corners before I solve middle centers.

Hey Mike,

That's neat I didn't think to do that. I guess I am cramming more into my super short term memory just before the solve, rather than utilizing my journeys to memorize the center cycle. I'll have to try your way as well and see which one I like better.

Btw, not that I want to lose it or anything, but when will somebody beat 15:22 for 5x5x5 BLD in competition? I feel like that record has been under the gun for so long, surely someone will grab it soon

Believe me, we're all working hard at it. I'm really hoping to get it June 26th at the Battle of Lexington. Of course, I'll probably manage it and still come in second place to Chester. (Kind of like last weekend, when I set the North American Record at multi and came in second place to Chester. And I got my personal best at 3x3x3 BLD and came in second place to Chester... Do you notice a pattern?)

I guess even though it doesn't look like it from the time, you set the bar pretty high. Congratulations on holding that record for so long!!! And I hope you get it back someday after one of us breaks it. With a sub-10.

perfect!
you could write the set-up for face D? for the other I'll try to get alone
Thanks a lot

I guess that you would do almost the same thing as shooting to D-face och X-centers. Solving Dr would be (r F2 e2 F2 r') U2 (r F2 e2 F2 r'). The other centers would be setups to Dr.

I'm not using this, but I think it might work just as good as U2 on X-centers.

now I can start studying
I must learn M2 to solve the central pieces of the edges.
