Weekly Go problems: Week 116

Here are the weekly Go problems for week 116.

Black plays first in all problems and all solutions are labeled ‘correct’. Have fun!

Easy Go problem

White’s shape is short of liberties. You just need to find the right move order.

We looked at a similar shape last time, but don’t assume that both situations are the same.

    Thanks for these Younggil, nice problems as always. Maybe it’s just a knowledge gap for me, but I actually had to think a bit about the easy one, so I imagine it’s a pretty tough problem for the level intended. Beginners, do not lose hope if you can’t solve this one immediately :).

    Intermediate one is also very important to demonstrate the consequences of a double low white approach (and then corner invasion) against various black pincers. In this circumstance it’s important to see how the situation arose as well, as it comes from a joseki starting with help (k3) on the left. A joseki discussion on this vs. last week would be most instructive I feel.

    The hard one is not so tough, and i feel confident I could find it in a game, but would probably not spot it if I were white! Might be good for me to not be so lazy and read my opponents patterns out further.

    Over the last couple of moths there’s been the jubango going on, and the book you announced, so I understand why there have been fewer of these problems of late, and don’t want to sound like I’m having a go, because I appreciate all the great (and free!) material on the site. However, the title might be in need of a rethink. Maybe call it monthly problems instead? Might be a more realistic target while Li/Sedol are receiving so much of the attention.

      Thanks very much for your summary Charlieh. I’m sorry for this late update, but we’ll try to keep it as weekly problems. Thanks. :)

      There were some other reasons why things got a bit slow in the earlier part of this year, but hopefully things will be better from now on. We’ll keep doing our best Charlie.

  2. Yes-ser-ri, that was the hardest easy one yet. It got me, it wasn’t what I expected. I left it then went back to it after awhile. Too bad I can’t do that in a game. Very tricky, I take the puzzle and try to work it into situations. Thank You, Phcull

    • David Ormerod says:

      Well done for solving the problem! It’s tricky, but after thinking about it for a long time, you’ll be more likely to remember this sort of situation when you see it in a game :)

  3. I’m surely making a oversight but… Can’t white play e2 instead of d2 at move 4 in the correct variation of the hard one ? Black seems to die this way…

  4. Simon, B can live in seki. See the variation where W plays f2 instead of d2 (same idea)

  5. I was impressed by the number of variations included in the hard problem. I was just playing through them not expecting any line to be included, and behold! they were there, not just the key variations. Better than most problem books in that regard. Makes one feel more secure in one’s reading. Keep it up! :-)

    • Younggil An says:

      Thanks for your kind comment Hippo. There’re still many possible variations which I couldn’t make though. I hope you enjoy other variations of the problems too. :)
