TuRBo Corners

[byu]

I am in the process of learning TuRBo corners, but the algorithms seem to be lengthy and hard to memorize. I know commutators can be intuitive ways to do corner 3-cycles, but I'm not sure. How should I go about learning TuRBo corners (I've already memorized all the edge algs)

 

[Shamah02]

yea just try and intuitively learn the algs as commutators

You see, I "kind of" understand commutators, but I can definitely only execute them with my eyes open, and blindfolded, well, I just can't do them. Any tips? (I have been looking at Ryan Heise's tutorial for Corner 3-Cycle Commutators but I still can't do them blindfolded)

 

[Shamah02]

well I'm kinda in the same boat your in...(can't execute commutators blindfolded.... except for the easier U/D ones) do you understand what the algorithms do?

 

[byu]

Yeah, if I'm looking at them

 

[Shamah02]

well try and make "rules" for yourself when executing commutators like you most likely did in F2L...

 

[byu]

rules... I don't understand

 

[Shamah02]

like say you had a commutator where you had 2 stickers on the U layer facing up and the lone corner in the D layer facing down. When you "see" this you know that it is not the simple commutator and needs 12 moves to be solved... If you see the same thing as the one above except the D layer sticker is on the R,L,F, or B face, then you would know that this can be solved using the simple 8 move commutator. I'm just speaking in general about all commutators and not the TuRBo ones though and this is hard to explain because you have to make the "rules" up yourself.

12 move commutator? Can you give me the alg?

 

[Shamah02]

well you do know that all corner 3 cycles can be solved in 8-12 moves and 12 being the worst case scenario... There are 6 cases that are 12 moves. This is one URB->ULF->DRF: U F2 U' F2 U' R2 U F2 U F2 U' R2

The other nasty ones are either mirrors or inverses of this one...
Daniel Beyer has a site of all corner commutators from URB but I can't find the link right now.

thats BH, not TuRBo or comms.........

 

[Shamah02]

I know. I was just speaking about commutators in general. And yes that is a commutator from the BH system...

How is it a commutator???? what is the ABA'B'??????

 

[Shamah02]

A=U F2 U' F2 U'
B=R2
A'=U F2 U F2 U'
B'=R2

 

[cmhardw]

A=U F2 U' F2 U'
B=R2
A'=U F2 U F2 U'
B'=R2

That is my favorite commutator out of all of the corner ones. The A part is really beautiful once you understand what it's effect is and how it achieves it.

Not all cases of that type need 12 moves.

case 1) UBL -> DLB -> URB: D L2 D R2 D' L2 D R2 D2
case 2) UBL -> DLB -> URF: R' U2 R U L2 U' R' U L2 U R

I do agree though that you learn to see, based on how the stickers are situated in relation to eachother, which case type you have. It's a lot like F2L in CFOP solving actually. You could memorize every possible case as an "algorithm" or learn a small group of types of commutators and learn how to recognize them on other faces or from different angles. That's all BH is really. As for R2 commutators, try looking at the BH corner commutators first to see if you find one you like. If those don't work, or you don't like them, then try freestlye using setups and A perms or setting up into one of a couple simple commutators that you can recognize easily.

Hope that helps at least a bit,
Chris

don't know if you already have seen my TuRBo corners algs. but maybe you find them a bit easier. I'm also in the process of learning them.

How can you not see it?!?

I really doubt that you actually use freestyle corners now.

Edit:

If you are transitioning between New/old Pochmann and Freestyle/TuRBo, try this: http://www.speedsolving.com/forum/showthread.php?t=9594

So your basically saying that if anyone makes a mistake, they don't do that????? If you made a mistake about speedcubing, could i say to you that i doubt you actually speedcube now?????

The analogy is more like if I don't understand the definition of Roux EO, you will doubt that I use Roux. I'm not doubting that you can solve the cube blindfolded as you claim. But I am questioning how "free" is your "freestyle."

I think he was saying that he was doubting your freestyle corners because ABA'B' is such a fundamental part of commutators.

EDIT: sorry i didn't read your post carefully enough
