  1. There are already a lot of variations for the hard problem, still the failure diagram I needed to work on most was White’s response at A4. After the next Black move, White can C2, which resolves to the main line, but also B2, which needed more thinking from my side.

    A great problem which I would never solve in a real game.

    • Younggil An says:

      A4 was a good response for white even if it doesn’t work if black answers correctly. I agree that it’d be very hard to solve in a real game, but it can still give you some ideas how to think differently in the situation.
      If you keep studying this sort of problems, they’ll help you to get stronger. :)

  2. Solved all problems just by looking at them, oh yeah!

  3. All three are quite nice, and as always the difficult one is special indeed!

    Kind regards,
    Paul

  4. for the hard one:

    when white A2,C2,B2,B1,A7,
    can white play at A6? if Black play at A4,then white A9,A10,C1, is it a ko?

    Thanks

  5. Now I see for the hard problem its not about the capture but is there a variation to contain whites possible attack and limit whites liberties. From what I see is that it could be fairly easy under the right circumstances

  6. I’m doing a terrible job of understanding why the diagram 2 solution for the hard problem is a good solution.

    I can’t think of any variation where the 11th stone isn’t dead. This is at best stealing a tiny bit of territory (via black stones at A5-A8) at a cost that more or less evens the scoring out anyway.
    How is it that this is the best solution to this problem?

  7. I think there is a typo in the solution to the Intermediate one: it should say “groups at B and C” instead of “groups at A and B”.

Speak your mind
