Practicing ZB/VHF2L

[Lofty]

is there any real good way to practice and memorize this... I am having great difficulty memorizing them. with OLL/PLL i was able to just do the alg over and over cause it would cycle back and forth every two or three times so at least half the time I could watch the pieces. plus i want to get good at them so that I am mirror neutral on them so I cut the cases in half.

Don't memorize them that way... If you only remember how the alg feels to execute, you can't learn the inverses as easily, not to mention OH. Understand how they work, it makes learning big sets of algs *much* easier.

I know 6 different Z-perms (plus inverses and reflection) even though I never tried learning more than 2. But after I've executed an alg slowly and watched what it does, I just won't forget it.

Could you elaborate on what it means to understand how algs work?

Example:

http://www.cubezone.be/conU1a.html, First case: y R' F' R U2 L R' F' L' R

What this algorithm does is move the existing F2L pair over, insert the last pair, knocks out an edge in the process. Then you do a U2 to move the edge, and finally insert the edge back into the first layer (by moving the existing F2L pairs out of the way).

Likewise, the same concept is used for the first case here: http://www.cubezone.be/conU1b.html, L F L' U2 R' L F R L'.

I only learned the first case I mentioned and I can do the other one just fine without 'learning' it.

Don't treat algs as magical move sequences that "just solve" the case. For relatively small sets like PLL you can do this and just memorize the moves or finger tricks, but something like ZBLL would be a real pain.

Execute the alg you're trying to learn very slowly and watch what it does. In case of an LL-alg, look at F2L-pieces. If it breaks some blocks, how does it put them back together? Or does it just take out a ce-pair or two and return it/them to F2L a bit differently? Once you understand what's happening with F2L, look at LL-pieces. There might be some solved bits already, like a ce-pair or square. Concentrate on the pieces that need to be solved, when/how do they get paired up etc.

Understanding commutators helps in many cases. And practising Heise, too.

lol yes I learned to do that with LL algs by watching the f2l pairs and the permutation or orientation as you moved them but f2l I'm just looking at differnet things then I am used to.
oh and about doing things OH I don't get OH amnesia I get two hand amnesia lol.
I'll look at Heise tonight and then later see about memorizing the VHF2L algs some more after.
