  1. For those who think they have found the solution to the hard problem (like I did) make sure to check White’s variation at move 4. I had a hard time figuring it out.

    One hint: “the opponent’s move is your move” works really well in this problem.

  2. Thanks David for this problems, and thanks Dieter for your advice. I followed it and got the correct solution.

  3. I don’t see how the correct answer for the intermediate problem is ko? I saw that one but kept looking till I found a ko answer, only to discover my first answer was correct, and the ko was wrong.

  4. Charlie H (2D) says:

    Nice problems as always! Intermediate and hard ones seemed a little easier than normal, though the hard one is still very interesting.
