An introduction to t-Go and a javascript viewer for t-Go SGF data from Little Golem
  • Malcolm Schonfield at 2017-06-15

    I would welcome feedback on this new article I’ve written: An introduction to toroidal Go.
    Also, I’ve made a tool for reviewing t-Go games from little Golem. It’s alpha software and provided on an “as is” basis: link.

    Cheers!

    Thank you for the great article.

    Regarding sizes, what would you think of a rectangular torus board? Examples: 9x17, 5x17, 7x15, 11x19, 7x19, 5x19.

    I created a user tournament: Torus Torus, Torus 2017

    Two games per opponent, starts in June 20.

    I’m getting the following error when trying to register for the tourney:

    HTTP ERROR 404

    Problem accessing /ng/a/index.jsp. Reason:

        /ng/a/index.jsp

    anyone seeing the same?

    Hi Gamesorry, I was able to register with no problems using Chrome on an android phone. Maybe you could try using a different browser? Also the one time I had a technical problem on little golem (it involved a triple ko!) I raised the ticket at the following URL and it got sorted out very quickly:

    bitbucket.org/rmalaschitz/littlegolem

    Oh I just looked it up in the User Tournament page instead of the clicking on the link above, and successfully registered.

    It might have something to do with the url:

    success: https://www.littlegolem.net/ng/a/Ctrn.action?dto.id=1065&view=

    failure: https://www.littlegolem.net/ng/a/Ctrn.action?view=&dto.id=1065

    hmm actually both work for me now. Not sure what happened

    Malcolm Schonfield, very cool!  Thanks for sharing! 

    ypercube ★, Interesting idea / question. 

    Another T-Go possibility is to add a shift/twist (literally) into the mapping of the surface such that on the 5x5 T-Go game with 25 intersections named: 

    • E1 E2 E3 E4 E5
    • D1 D2 D3 D4 D5
    • C1 C2 C3 C4 C5
    • B1 B2 B3 B4 B5
    • A1 A2 A3 A4 A5

    “A1” would connect to “B5” (instead of A5); “B1”  would connect to “C5”; “C1” would connect to “D5”; and "E1would connect to “A5” (instead of E5).... 

    The above is a one unit shift/twist; but a 2 or more unit shift could also be done.

    @Sighris yes, that’s another way to wrap a square in a torus.

    I think there are other way as well, to wrap a torus. Not necessarily with a rectangular shape.

    Example, with shifts both vertical and horizontal and an a shape of a 3x3 square with a square removed:

    A3 B3 C3

    A2 B2 B3

    A1 B1

    The tiling:

    C2 A1 B1 A3 B3 C3 ...

    A3 B3 C3 A2 B2 C2 ...

    A2 B2 C2 A1 B1 ...

    A1 B1 A3 B3 C3 ...

  • ypercube ★ at 2017-06-20

    Correction for the shape (tiling is correct):

    A3 B3 C3

    A2 B2 C2

    A1 B1

    @ypercube, about your question "what would you think of a rectangular torus board? Examples: 9x17, 5x17, 7x15, 11x19, 7x19, 5x19"

    Yes, these would probably be nice spaces to play Go on. I don’t think it necessary has to be odd numbers. Still, I would expect the game to be have less strategic potential with narrow boards. It could be nice to compare 7x19 (=133 points) with 11*11 (121 points).

    @Sighris and ypercube, I hadn’t thought of that. I would call these variants “twisted toroidal Go”. These also would be nice spaces to play Go on.

    Thanks both of you for your kind words about my article.
