  2. But What happen after black D 3 if white plays G2

    • Leonid Entin says:

      If W G2 then B D2 is still sente but if White answers D3 at F2 then Black doesn’t seem to be able to take corner in sente anymore.

      • David Ormerod says:

        As Leonid said, answering D3 with G2 or J1 is almost the same.

        If white answers D3 with F2 she can get sente, but at a cost, because white won’t be completely alive after that. It’s complicated to explain, so I’ve updated the SGF and PDF files to show you.

        You might want to just download the PDF if your browser is caching the SGF file.

  3. David, your latest directions with the problems allow me to find the correct solution without feeling you gave away too much! The sweet spot between guided success and original reading.

    Congratulations!

  4. Thanks for the problems. 1st and 2nd one are perfect. 3rd one is a little bit too well known, but you only have so many good problems!

    • David Ormerod says:

      Thanks! You said the hard problem was well known another week as well, which is strange because both those times I made the problem from scratch – whereas on other occasions I’ve used problems from classical collections, which I expected would be recognized.

      I’m guessing you must mean the tesuji or idea behind the problem is well known? That’s true, because I nearly always start with a specific technique in mind when making a problem. In that sense, I guess most Go things since the Xuanxuan Qijing are postmodern… :)

Speak your mind
