  1. Three in a row in a matter of a minute or two. Has the recent study of L&D paid off or do we have a hard problem on a summer holiday? (guess not, it’s cold winters in Australie …)

    • David Ormerod says:

      Maybe a bit of both I think?

      The problems were getting harder and harder at one stage, then Younggil said they were too hard, so the recent problems are a bit easier than before 🙂

  2. Cute, as always. The difficult one is as always a bit more intricate, great fun!

    Kind regards,
    Paul

    • David Ormerod says:

      Thanks Paul, it’s a small one, but I still thought it was interesting. Glad to hear you enjoyed it.

  3. Well this is a first! I actually found the easy problem the most interesting! 🙂
    Why? The problem still has a solution with white S3 and black S4 on the board: call it a bonus (harder) problem for anyone interested 🙂

    • David Ormerod says:

      Haha, I thought about that too Hippo 😉

    • posetcay says:

      Can you show the variation with s3 and s4 on board, i cant find the solution

      • With S3, S4 on the board, black can play O2, and if black connects solidly, P1 wins.
        But… but… but…
        But white plays P1, the vital point (and the shape point in relation to the cutting point at Q2), and now if black P2 then white Q2, and those two hanes are woth an extra liberty because black cannot approach from either side. So in fact black cannot save the N2+N3 stones.

        P1 is a great example of a vital point.

  4. Oops – no it hasn’t. OK, the problem is why not, then… :-]

      Always start with black,the best moves are for blk.You train your eyes to see the best moves then after awhile they will just pop out to you.It does take sometime to study first.

    • you sent me for a loop, haha

  5. phcull,I said that says:

    Great puzzles!

  6. Charlie H (3D) says:

    Ha! I read hippos first post, noting why the usual didn’t pattern wouldn’t work as I solved It first time, then proceeded to spend ages trying to work it out before finally giving up and reading the later posts in search of a solution :). Guess that’ll learn me for reading selectively.
    Anyway, nice problems, and a little easier than they have been in the past, so if you only try the easy one or inter normally, have a go at the next one this week :).

    • 🙁 Sorry again…

      • Anonymous says:

        No worries, a lot of the time I only solve the problems here cos I’m looking for a solution that I’d not have time to consider, or would not be confident enough to play in real games. Having a ‘false problem’ every now and again is good to try to get your problem solving brain and game brain closer together.

  7. Thanks David for the problems, very cute and not very dificult to me.

  8. Maybe a site question: I cannot enlarge the problems on my iPad with the “two fingers movement” anymore, I could until a few weeks ago, I guess. Now it is hard to target the points where to play. My fault somewhere, or could this be repaired? Thank you in advance! And the black Go shop line is in the middle of what I type right now, in the blind, I hope it makes sense.

    Kind regards,
    Paul

      Hi Paul,

      We’re in the process of switching the site over to use Glift. I disabled zoom because many people were having problems with iPad zooming in when they were tapping the next move button, but that means zoom won’t work anymore. I’ll look into improving things later so zoom is only disabled on pages that have game records.

      Soon we’ll change these problems over to use Glift too, and then they’ll be bigger and zoom will be less of an issue. In the meantime, I’m sorry if there are some teething problems during the change over.

      The banner at the bottom shouldn’t be covering the comments box and I can’t see that happening on iPad. If that keeps happening, would you be able to email me a screenshot of that please?

      Thanks

      • Thank you for your answer, David. I am not sure about Glift, I like the things as they are/were right now, no need to change for me, a simple end user on an iPad Mini. I saw Glift somewhere else, there was one issue I wasn’t impressed with: the board was white, as were the white stones, so readability didn’t improve. Also, the latest stone played was difficult to see, I prefer the red dot as used here. Is this comment useful to you? Good luck with the ‘internal work’, I hope we see the good things coming out of it!

        Kind regards,
        Paul
