    Hi Younggil, great problems as always! Not too taxing this week, but very clear on the lesson being taught. The intermediate one especially is a shape all single digit kyus should learn if they don’t already know, as it arises from shapes such as playing q4 to protect an o3 cut (without the o2 p3 exchange). Even the hard one also is pretty neat and tidy if not outrageously difficult.

  2. Applying the fundamentals of life & death allowed me to find this one very quickly again. Thanks!

  3. thanks Mr.An i got it in one try….strengthen your basic in Go really is an essential to become strong…….thanks for the problem….

  4. I can’t help wondering if people who thought the ‘hard’ problem was straightforward read all of the variations from scratch. I struggled with the case where white can capture two individual stones. In a real game no one is there to tell us there is a way for b to kill – so we really need to try to read the whole thing out in its entirety.

      I totally agree with you Vlad. 🙂

    • Charlie H (2D) says:

      Most of the variations given in the pdf where pretty consistent with what I was thinking about when trying to solve this problem, but if others found it hard I’m more than happy to put it down to just natural variation. Some of the problems put up here take me ages and then I still get them wrong, while others about my grade say they took no effort at all. I guess it’s just that different players have different holes in knowledge.

  5. For a change I found all three problems pretty easy.

  6. Benjamin H says:

    In the hard problem, I am a bit suprised that the sgf does not cover the variation when white simply blocks (I do not give the coordinates to avoid spoilers). It looks like the most natural answer to me, and it is the sequence that prevented me from solving this problem.

    • Younggil An says:

      Oh, really? Hmm, I tried to guess, but I couldn’t fine where you meant. Is it the first answer or second? Which line is it?

      • Charlie H (2D) says:

        Maybe he means wf3 after bg3? In this case bg2 seems fine… Or maybe it’s wf2 after bf1? In this case e1 is fairly clearly right, but I think that’s already included as a variation.

        • Younggil An says:

          Thanks for your thought. I reckon the first one was right, since there’s no variation about the move.

  7. Thibault P. says:

    I like how the easy problem comes from Lee Sedol’s game in the quarter final od th Samsung cup 🙂

  8. Thibault P. says:

    Park Junghwan’s, not Lee Sedol’s…
