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.
