  1. intermediate is good

  2. Had an easier time with the hard one, some how I just could not see the intermediate.

    • Younggil An says:

      Yes, the intermediate problem seems to be quite hard, but interesting. 🙂

      • Takaburro says:

        Hard problem is hardest than intermediate. Cause is easiest to figure how to make W to fill he’s liberties. While hardest you need to find the shape’s hearth properly

  3. Very nice, as said before: the intermediate problem was quite intricate. Thank you!

    Kind regards,
    Paul

  4. For the intermediate I read that you could save the stones in the middle with p7 o6 o4, but missed that white could still connect out by capturing at p8. The actual solution is much nicer!

    • Actually p7 o6 o4 results in a ko anyway if white resists strongly so I was just wrong 🙂

      • Younggil An says:

        That’s alright. That’s just a practice, and that’ll be helpful for you to think and read in different way. 🙂

  5. This weeks problems are easy i think. i finished them all about 2 minutes 🙂 generally i spent lots of time for hard and intermediate.

  6. What is the current status of Dosetsu’s “masterpiece”, often listed as 120 of Igo Hatsuyo-ron?
    Shuko and his students came up with a solution, but a few years ago, a German amateur discovered that capturing the hane-seki at the right moment led to a win in the endgame by a small margin. Maybe this could be a problem of the week?:)

  7. Gil Dogon says:

    Yes, problems this time were relatively easier, but I am quite OK with that, otherwise I would not have been able to solve them 🙂

    Intermediate is quite cool, though not too difficult because of the forced sequence, It stills seems a new shape I have not seen before ….

    Hard one was nice, and after D1 tesuji, I would just add another (failed) variation for W at F1 , refuted by B D2 ….

  8. All good problems. Keep ’em coming 🙂
