  1. hard problem:
    in the solution black takes at Q3 and white ataris at Q4. But what if white throws in at Q2 instead of atari, the solution is a ko?

  2. That difficult nr. 3 is quite cute, great problem! Thank you for showing.

    Kind regards,
    Paul

    • By the way, as far as I can see, the problem solution is also the best endgame solution here. That is: white playing all out gives him the best result. That often is not the case, so that makes this problem extra nice to me.

      Kind regards,
      Paul

  3. Hello David. Thanks for the problems… I could not solve the hard one this time.

  4. The easy problem’s description: “You need to choose between expanding your eyespace and defending a vital point…”

    But the solution both expands eyespace and defends the vital point. There is no choosing here.

  5. I solved easily the easy and intermediate problems. The hard one was more difficult but easier than the hard problem of week 136.

  6. Easy one is an important position to know for beginners, simple but good choice. Intermediate one was a little too obvious for me, the right move just screams out loud. Ah but the hard problem, I spent 20 minutes without trying a single move and when I finally found the right variation, I couldn’t believe how beautiful it was. The satisfaction I felt was immense. Easily the best tsumego I have ever solved.
