  1. last problem, I had ever seen from hikaru no go 😀

    • David Ormerod says:

      That’s right. I remembered it from Hikaru no Go too :). I was wondering how long it would take for someone else to notice. Not very long!

  2. Brandon Matt says:

    All problems were really nice and involved some to a lot of thinking. I really enjoyed the intermediate problem of attacking. I think it’s the first one that’s been part of the problems since they’ve started. Most have always been create life instead of attack and kill!!!

    Really good advanced problem. it’s amazing how certain moves, when not in the right order can cause a lot of havoc.

    The easy problem was one of those “OMG Duh!” moments when solving it.

    Great job and hope to see more attacking problems in the future.

    • David Ormerod says:

      Thanks Brandon, to paraphrase Rin Kaiho, ‘Go is move order’. More attacking problems are coming next week :).

  3. Thanks to the spirit of Hikaru, I could solve the hard one in a glance too. Seems like we’re all inhabite!

    • David Ormerod says:

      Heheh, I thought of Hikaru no Go when I was selecting the problem too. I think it’s actually from the Chinese Xuanxuan Qi Jing originally and I can’t remember if the Hikaru one was exactly the same, but it definitely used the same tesuji in the corner.

      That this could make such an impression on people’s minds does raise interesting questions about Hikaru no Go as an education medium. Maybe something that would interest you Dieter? 😉

  4. Indeed, all three were nice, well chosen! The first one: OOPS! and I was awake. The second one: a nice one way street, I often fail to see the end result in advance. The third one: juggling on the square mm, with a concept seen in many problems that only appears in the correct solution. I will not name the concept, only that it has nothing to do with abundance.

    Kind regards,
    Paul

  5. The hard one haven’t be to difficult but the intermediate I’m stayed to think “How to kill a such shape unconditionnaly ?” Until I realize that “unconditionnaly” isn’t specified anywhere 🙂

    Thank for the problems.

  6. My browser (Firefox) used to open the links as sgf files automatically. Now, no go. Has anyone else had this problem and found a solution?

    • David Ormerod says:

      Max, it will depend on what program you have associated with SGF files. Also there will be a setting in your browser for how to handle different file types. E.g. whether to open or just download them.

  7. Tony Purcell says:

    Very instructive problems. I haven’t read Hikaru No Go so the last problem was very hard, just goes to show proverbs can sometimes be trusted.

    • David Ormerod says:

      Yes, it is hard problem, even if you’ve seen it before. Knowing the first move is one thing, knowing why it works and why other moves don’t is something else :).

  8. Ha ha, I took the clue about it being from Hikaru too seriously and focused too much on how that problem had been oriented on the board. I should have read instead of relying on memory.

    • David Ormerod says:

      Yes, if you can read things out you don’t need to remember the solution. I think the shape in Hikaru no Go was slightly different, but the situation in the corner and the tesuji were the same.

  9. haha funny one 🙂

  10. I’m not sure if anyone will look at these anymore, but in the hard problem, why isn’t white 4 at T3?
