    Fortunately I can still see them from desktop.

    So uni started and I’ve been a lot more busy, but I’m still trying to practice my 3-Style with Anki. I’ve switched from having 1 card per commutator to 1 card for both a commutator and its inverse. This will speed up my learning but very likely slow down my recognition for when I encounter a letter pair that corresponds to an inverse. I’ll try to practice that when I’ve finished learning all the algs first.

    The tool I was creating is a little simpler now. It only fetches a few sheets (an old one by Jack Cai and Elliott Kobelansky’s). I use Jack Cai’s algs mainly as that’s the one I found first, but since it has many typos, I replace (via code) the ones I dislike with Elliott’s. Then I generate the Anki cards (with both comm and inverse). Right now I’m learning 378 corner commutators via 189 cards.

    What I’ve really grown to like is a mix of Elliott Kobelansky’s notation and standard notation.

    • Standard notation: [D' U': [R D' R', U2]]
      • In English:
        1. Set up with D' U'
        2. Do the insertion R D' R'
        3. Do the interchange U2
        4. Undo the insertion with R D R'
        5. Undo the interchange with U2
        6. Undo the setup with U D
    • Elliott’s notation: D': U' / R D' R'
      • In English:
        1. Set up with D'
        2. Do the pseudo-interchange U'
        3. Do the insertion R D' R'
        4. Do the pseudo-interchange twice U2
        5. Undo the insertion R D R'
        6. Do the pseudo-interchange again U'
        7. Undo the setup with D'
    • The mix I like: [D': [U' / R D' R']]
      • Exactly the same as Elliott’s notation, but I find it easier to read.

    What I do is I have both the standard notation and my modified Elliott notation on each card. That way I can try both and use the one that’s easiest to learn (it’s not always one or the other).
    Parsing Elliott’s notation and generating the mix is all automated, of course ;)








  • Nice! Will you publish your tool?

    Probably! But I’m still trying to figure out how to organize it all. I also discovered more algorithm sheets (probably should have started by doing that research before parsing Jack Cai’s sheet). I’m trying to make it as general purpose as possible and also trying not to confuse myself while learning.

    Also it’s hard to reason about the best way to learn when I don’t know much yet (which leads to me implementing some interesting YAGNI), but I’ll update the tool as I go and maybe when I’m done/happy enough I’ll publish it. It’s all in Python though (to deal with the sheets via Pandas) and I think it’s not ideal because most cubers prefer online webapps AFAIK.


  • Sounds fun. I still don’t completely understand commutators so I never learned 3-Style. What method did you use before and what were your times?

    My PB is 3:07 with M2/OP. I’m going against the usual recommendation of “practice a lot of memo before learning 3-Style” but I’ve also read a few comments against doing that saying to just start with 3-Style immediately. Also knowing full 3-Style just sounds amazing.

    Do you do BLD too? What are your times and method?


  • I started learning 3-Style and I made my own tool to parse Jack Cai’s sheets and create flashcards for the algorithms. I even made it generate the algorithms that Jack Cai marked as “inverse of …” by inverting said algorithm. Since it’s best to start with pure commutators, I made the tool replace all appearances of pure commutators other algs with the pair name. I think it’s very useful, much more intuitive and makes learning much faster. Hopefully I’m able to learn all of 3-Style before uni break ends.

    (Btw: I posted on the last discussion thread but it doesn’t seem to show up. I hope this one does)
