if I finished 3x2x2 block, and I want to orient all last 7 edes, is there any subset, which can do that?
If at least on if those edges is oriented correctly, then you can do a D2 to pair up one or two pairs. Then take it out and insert it properly. Then deal with the other one.Hello everybody,
So, I’m doing my f2l and after solving two pairs in the front right slot and back left slot, I have a situation which I can only solve really inefficiently.
The other two corner pieces are both solved but the front left edge piece is in the back right slot and vice versa.
All I need to do is swap the front left edge piece and back right edge piece. Is there a beautifully efficient way to do this?
edit: I’ve just realised that there are still many situations that may arise depending on the orientation of the edge pieces...
Thanks
4 cases: none flipped, right flipped, left flipped, both flipped
2 cases per case: with or without any other slots solved
If neither edges are flipped:
Front left and back right slots are unsolved: D' R L U2 R' L' D
Front left or back right slot solved: (R U R') (L U' L') (R U' R') U (L U L')
E: worked out other cases
Back left is flipped
LF/RB slots solved: R L U' R' (F R' F R) L' U' (L U2 L') U' (L U L')
Front right is flipped
LF/RB slots solved: (F R' F R) U' L U (R U2 R') U' L' U (R U' R' )
Both are flipped
LF/RB slots solved: (L R U' L' R') (F Lw' U' Lw2) U L U' M'
I didn't feel like figuring out cases using empty slots.
Also note that I use ZZ, never really deal with flipped edges, and don't know if there are any fancy CFOP tricks that others might know.
@Smiles ?
E2: crud, I just realized that I did this for the wrong pair of slots...
Cases should be able to be mirrored though
E3: or you can do a y/y' and use these
(I did say that I use ZZ. I can't think like a CFOPer)
Is it worth my time to try and learn zz-ct if I'm sub 15 already? I'd like to be at least sub 15 with another method than CFOP, and I don't particularly like Roux. ZZ seems interesting, and I'd like to learn a subset that few people have become fast with.
especially when centers are misaligned (r/r' off)
Random tip: for RrMU algs, you can do a front-back reflection and it'll still be RrMU. Even if you want to learn the alg as a mirror, it doesn't mean you have to learn a lefty version. (This also works for RUD and RUL algs, but it doesn't work for RUF algs: RUF algs become RUB if you mirror them front to back.)Hi, it’s me again, 18 second solver, refining my awful olls...
So, olls 53 and 54... seems so little agreement regarding the best algs for these two cases and also whether or not (generally speaking) you should learn them together as mirrors of one another or learn two right handed algs...
Anyone have anything useful, interesting or unusual to contribute (based on their own self-teaching) before I just go with “jperm’s YouTube mirrors”?

I mainly use r U2 R' U' R U R' U' R U' r' and r' U2 R U R' U' R U R' U r for these cases. If you want, you could also learn all the versions of this alg (lefty/righty, inverses, front-back mirrors) to eliminate pre-AUF completely.
I am ashamed to admit that I can't do double flicks with my right hand, so yes.Do you do the U2 with your left hand on both of them?
