    I'm curious about how people do some particularly difficult 3-cycle cases. So I'd like to try to post a new 3 cycle each day, and ask how you do that particular case. Share your algorithm, discuss it if you'd like, and offer any alternatives that you may think are good.

    Also, if you find a case particularly troubling, request it and I'll put that up as the next case to discuss.

    Day 1 - ULB-> RFU -> LUF (MF)
    Noahaha: [F: [R' F' R2 F R , U2]] (14)
    Set up into a column case (DRF -> UFR)

    DeeDubb: [R F': [L2, U R U']] (12)
    Set up into (RUB -> DRF)

    My alt alg: [F: [R2 D' R2 D R2, U2]] (14)
    Set up into a column case (DRF -> UFR)

    Cale S: y R' F U2 F' R F R' U2 R F' y' (10)
    move optimal?

    ottozing: R' U R' D U R D' R' U2 R D R' U D' R U' R (17)

    CyanSandwich: [R F2: [U' L' U, R2]] (12)
    Set up into (RUB -> RDF)

    h2f: [z' x' D' R: [D2, R U2 R']] (11)
    sets up into (UFL -> DFR)

    My alt to h2f:
    [y' R' D: [R2, D L2 D']] (11)
    Use y' to avoid the double rotation

    bobthegiraffemonkey: [R2' U' R U': [R' D' R, U2]] (16)

    mark49152: [R2 F: [U2, L' D L]] (12)

    moralsh: [R2 F2: R, F L2 F'] (11)

    Hari: R U R' D' R' D R U2 R' D' R U2 D R U' R' (16)

    Day 2 - ULB->BDR->DBL (TX)

    Day 3 - ULB -> URF -> DBL (CX)

    Day 4 - ULB -> FUR -> BRU (JQ)

    Day 5: ULB -> LUF -> BRU (FQ)

    Day 6 - UBL -> DBL -> LUF (XF)


    Day 7: UBL -> BUR -> DFL (QU)

    Day 8: UBL -> DBR -> RFU (WM)
    Noahaha [z' x': [U2 , R' D R]] (8)

    DeeDubb: [y: [R2, D' L D]] (8)
    I tend to minimize rotations on pure comms to either a single x or single y.

    DeeDubb alt: [L: [U, L D2 L']] (9)
    A nice little rotationless 9 mover I came up with while I was bored.

    H2f: [x U: [D2, R U R']]
    (10)

    ottozing: [R2 U: [R D R' , U2]] (11)

    bobthegiraffemonkey: [z' U R: [U, R D' R']] (11)

    dbf: [R2: [L' D L, U2]] (10)

    moralsh: [x y: [U2, R' D R]] (8)

    mark49152: [R' D R': [x R2: [D2, R U R']]] (16)
    R' D R' setup up to A perm, just because I am so comfortable and quick with A perm :)

    adimare: [x U: [D2, R U R']] (10)

    Altha: [z': [B2, R' F R]] (8)
    z double flick B2s with LH

    Meneghetti: [D' x': [D', R U' R']] (10)
    I set it up to VM, which I really like.

    Day 9: UBL->DFL->URF(UC)

    Day 10: ULB -> UFL -> DFR (DV)

    Day 11: ULB -> RFU -> BDR (MT)

    Guessing you meant UBL->RUF->LUF (which in Speffz is MF, not NF).

    I use Noah's alg, I don't think I ever use setups with more than one move for corner comms.

    I use [R F2: [U' L' U, R2]]

    I think your one's better.

    @DeeDubb Thank you for the thread, its very helpfull.

    ULB-> RFU -> LUF I did like Noah. I think your way is better - easy to follow, setup makes a case I like. I was thinking of this

    z' x' D' R: [D2, R U2 R'] [11 HTM] but with rotations.

    I seem to have [R2'U'RU': [R'D'R, U2]] written down in my alg sheet, but I'll probably end up switching to something from this thread when I look through them later.

    actually, I like yours a lot, but I'd change it to:

    [y' R' D: [R2, D L2 D']]

    I use Noah's, but I might switch to Jayden's... No rotations, RUD only, no R2's, only one U2... it looks awesome!

    I use currently Noah's one but I'm gonna switch to Jayden's alg

    I do [R' D2 x' z; [R U R', D2]]

    Which is obviously garbage. I'm switching to Jayden's.
    This thread's going to force me to eventually have a good alg for every case :)

    I like Jayden's. I used with D' setup but it's weak and I mus think what I'm doing. I'm thinking about [R' D: [D R2 D', L2] but with z' rotation: z' U' R: [R U2 R', D2] (11).

    Funny thing - in my sheet I have Deedubb's alg but why I didnt use it? This thread makes me force to use better algs and look through my list.

    Funny, I just realised that's the same as Jayden's, except I think of it as U exchange rather than D exchange. I didn't realise a commutator could be written multiple ways with different exchanges, but I suppose with setups that makes sense.

    Day 1: [R2 F2: R, F L2 F'] although I like some of the ones posted here more

    Day 2: [D F': L U L', D2]

    2) [U2 L': [L' U L, D2]], I generally try to avoid lefty stuff but some of them I don't mind.
