  1. I miss when these came out more often.

      It’s been a busy year, especially with Learn Go Week. Are you running an event, by the way?

      We’ll try to post more often again over the next few months 🙂

  2. Nice problems as always!
    But why I can’t download sgf file?

    • Younggil An says:

      You can click the ‘Download SGF File (Go Ga Record)’ to download.

    • David Ormerod says:

      We recently moved to a new server (to make the website faster) and there are still some minor configuration issues to sort out.

      This will be fixed very soon, but in the meantime you can right click and select ‘save as’, or you can use the link Younggil mentioned, which has more information for the browser.

  3. Thanks, David. Good problems and worth to remember them.

  4. Ok, could someone please explain the solution on the Hard Question? Why does a “ko” matter there? I’ve been looking at it for almost an hour, and every way I play it white just ends up taking black anyway. I must be missing something, but I’m clearly not experienced enough to see what.

    • If white captures four black stones at Q2, then black can play R2 and eats white’s three stones.

      • Younggil An says:

        Hi Chris, you can download the SGF file and you can clearly see the other variations which includes your question. 🙂

  5. I fail to fathom why E2 is a mistake on the intermediate problem. Can someone please explain it to me ? Many thanks !

  6. (forgot my email)

  7. as usually, I can easily make/do hard problem just inter took me more time~

    great problems, would love to have more problems per week =P

  8. The new player is improving all the time, however, one option that was present in the old player seems to be missing. There you could try different responses for white and then try to find out by yourself the correct continuation for black. Now you can only follow the first line or see all variants that show you all correct moves.

    For instance, in the hard problem you’d like to figure out what happens in case B answers S1T2R1 with P1 and not S6 but the stone can’t be actually placed at P1 unless all variants are shown.

  10. Woah…. I think this the first time ive gotten all 3 problems right on the first try. XD

  11. Ah, that new interface 🙂
    Also, the intermediate problem is very nice. Definitely the kind of thing I would miss or misread in my games.

    • Thanks! We’ve been working hard over the last few weeks to improve the UI of Glift, the go viewer / problem player.

  12. The new interface also makes it just that little harder to navigate from the problem setting, which is perfect to keep you in solving mode.

    The hard problem was not really hard for me this time. Somehow I expected ko and/or UTS. I guess al the problem solving of late is indeed improving my intuition.

    Thanks!

    • David Ormerod says:

      Thanks Dieter, we think the new interface is better too, and will be even better in the long run, even though some people didn’t want us to change things. Hopefully more people will like it when they see how we use it later.

      As far as under the stones goes, the hard problem is of the easier kind. Still, it’s not that easy. You seem to have a good eye for under the stones problems 🙂

  13. Actually, in the hard problem you dont need to see the UTS to live, since in the UTS variation b can live at the end by playing T5
