I am using 32223 right now, but I have wanted to test Yau method also. Where can I find a tutorial?

Robert Yau's old tutorial is here. Although he no longer recommends this method, so instead try Sebastian's video tutorial.

Here are 12 full reconstructions.

out of curiosity, why dosent he reccomend the old way of doing yau?

Can I get some help with 5x5 algs? Im looking for better last three edges algs. .Right now im trying to learn these: http://www.bigcubes.com/5x5x5/lastedges.html

 

[Schmidt]

There was a recent 5x5x5 thread with a nice video of the last 3/4 edges. Basically it was "Don't put anything in the U, but connect two pieces corect and slice the incorect piece over the last piece, do R U R' F R' F' R ( or any flip alg) and slice back to make a corect tredge" Not his words, so I hope it makes sense, or else find the vid.

 

[Hays]

For 6x6, does anybody, for centers, make a 2x2 piece, and then get the pieces on the ends for that 2x2 block, making a 2x4? And then just making 2 bars, connecting them to the 2x4 one at a time, like normal? That's what I do, but I'm slow right now. (5ish minutes)

I do this only if I see it's an easy case for it. I usually default to bars, but there are some cool tricks that you can do with 6x6 centers if you get the right cases and you can identify them.

 

[JianhanC]

Is there any way to furthur reduce the popping rate on a 6x6? I rounded the corner stalks and the oblique center stalks and it still pops about twice a solve.

for the 3rd ell case its written in commutator notation (which i cant really undestand). could anyone tell me the algotithm in normal notation?

 

[Schmidt]

[F' R u2 R' F, U] = (F' R u2 R' F) U (F' R u2 R' F') U'
[x, y] = x y x' y'

Is x' not the inverse of x?? And in that case is (F' R u2 R' F) or (F' R u2 R' F') correctly written?

Can anyone help me with some common 6x6 cases for the last two centers. I have to make the 4x4 case and then if there is any other pieces which need to be solved i do the standard alg to solve the last two incorrect pieces (which aren't in the corner of my 4x4 center.) Thanks!

Just make the first 1x4 bar you see, doesn't matter if it's an inner or outer one. Then make another one, so that you'll have a 2x4 block. Then make a third inner bar. Solve the last outer bar like you would on a 5x5. This video should help: http://www.youtube.com/watch?v=YsdFL0kS2-I

I'm bored. This is an OBLBL on 4x4 example solve. In the scramble, lowercase denotes wide turns. In the solve, lowercase letters denote slice turns, and ___w denotes wide turns.

Am I efficient enough with my blockbuilding? >.< Movecount includes rotations. Does it seem like the movecount is too high?

****!!! I tried to do what you did Jaycee but I somehow messed up. I put it in to alg.garron.us and I got the error.

Might as well show how I basically do it even you cant do it yourself.

My last average of 12 was 1:23.31 so (83.31 seconds/171 turns)= 2.05 TPS

I might try and do a 7x7 reconstruction tomorrow.

BTW I did a 7x7 solve with OBLBL and got a 12:04.51

 

[Ickenicke]

OBLBL seems very interesting. I think I will start learning it. What is the most important thing to think at?

Also, what is the fastest time anyone ever have got with this method?

 

[PandaCuber]

I just switched. Its fun, but also hard .

 

[somerandomkidmike]

I suppose this would be an okay place to ask. So if somebody averaged 1 minute on the 4x4, what would be the equivalent times on the 5x5, 6x6 and 7x7?

Whats your 3x3 time?

 

[Jaycee]

Nice movecount. :O you even had OParity too! I'm curious about this, though :

Down Center(Blue): U' 3R Rw U l2 U' l2 (9/36)
BY Edge-Center Pair: U Rw U' Rw' U2' y' R' U' R y U' Rw U2 Rw' (12/48)

BW Edge-Center Pair: l U2 l' R y' R' U' R y U l U2 l' (15/74)
BW Edge-Center Pair: U2 Rw U' Rw' U R U2 R' U Rw' U2 Rw (12/86)

If you could explain how you do this or maybe just try to do another example solve it'd be great. This seems different from how I do my centers and edges.

It is indeed a very interesting method! http://mzrg.com/rubik/methods/OBLBL/ gives some basic tips, but I recommend focusing very hard on transitions. If I'm not completely focused during specific parts of my solve I end up pausing for 3-7 seconds. These parts are : from the second center to the first edge pairing of the RouxBlock and from the last block layer to edge pairing. At least, these are the worst parts of my solves in terms of smooth transitioning.

Michael Gottlieb (qqwref) and Justin Thomas (uberCuber) are the two fastest OBLBL users that I know of (QQ is the inventor of the method!), so one of them can probably tell you what the fastest time is

I just switched. Its fun, but also hard .

I find it very fun as well. It only took me a couple days to get used to it so it's not really "hard" anymore. Practice, practice, practice! What do you average?

 

[PandaCuber]

Someone post merge this if you want.

Ao3 with OBLBL: 2:27.20 (σ = 0.00) First time I ever got 0.00!
2:27.20, 2:08.59, 2:29.77

Slow, but so much fun.
Im still trying to figure out how the methods work. Did it a little intuitive.
2 pair edging and Petrus w/ COLL for the win.
