  1. How is it that I got the Intermediate and Hard both on their second try but could not figure out the Easy one after many tries and had to give up and consult the PDF? Perhaps I needed that one warm-up to get the brain working…

      I thought the easy one is a basic life & death problem, but if it’s not that easy, it’s my fault. I’ll be happy if you learn something new through the problems. :)

    • It is easy because it is a “basic” shape. It just happens to be tough to read out if you do not know it :)

      Also, for the hard one (for example) there is really only one move that does not immediately let white live, so it is easy to get started on the right track :)

    • Ha. I had a similar problem.

  2. Thanks for the problems. The first one made me think a lot!!

  3. The Easy and Intermediate Problems were both tough for me, but I got the Hard Problem in only a couple of tries. The Hard was still fun, but compared to most of the other Hard and Intermediate Problems it didn’t seem all that difficult.
    Thanks again for posting these Weekly Go Problems. I enjoy every update.

    • Younggil An says:

      I thought the hard problems before were too difficult or hard to solve, so I downgraded the hard one a bit.
      If it’s too easy for you, you can try to solve the problem at once. In your actual game, you only have single chance to try. :)

  4. I think the problems were nicely judged. The easy problem is worth remembering, it’s a shape that occurs often in real games.

  5. I thought all the problems were pretty easy.

  6. In the easy problem, readers may appreciate if you show the sequence leading up to this, and especially why the push at Q2 is a mistake.
