Easy Go problem

When you’re trying to reduce a group’s liberties, it’s usually better not to allow it to extend in a straight line.

Intermediate Go problem

Separating White’s groups is surprisingly tricky. You’ll need to have a tesuji prepared.

  1. Thanks, David.
    The intermediate one is very good and useful, indeed.

    • Agree with jangalf, the intermediate was my favourite too. Perhaps those kind of connection/disconnection problems are more practical than abstruse life and death… easy to get wrong in a fast game.

    Looking at the hard problem, it does not feel like the first move is exactly sente for black. White can pretty much ignore black’s first move and directly attack q3 with p3. Perhaps I am missing something here, but it feels like something is not quite right in this problem. Even if black descends at l1, white can ignore it for a turn, no? Thanks!

    • If White p3, o3 would be double atari.
      Black would live by taking either side.

      Anyway, thanks Go Game Guru for these problems!

    Thanks for an easy problem that is actually easy.

    Well David, the hard problem this time was way too hard for me, as I am being quite lazy at this time of night, and it has so many variations, which I explored, being lazy as I am. It is indeed quite original I feel and I wonder, have you come up with it yourself ?

    • Younggil An says:

      Thanks for your note and the question Gil.

      The problems are already existed, but David edited to make it nicer, and I also helped him to make some variations, because some of hard problems are quite tricky.

      I hope you to enjoy solving those problems. 🙂

  5. The hard one was really interesting though I wasn’t able to solve it.
