Intermediate Go problem

This is the continuation of a common joseki. How can you make use of Black’s single stone on the left side?

The joseki in question was discussed in game 3 of the Gu Li – Lee Sedol Jubango (as a possible variation at move 10 in the top left corner).

Hard Go problem

This problem is from a real game and was sent to us by Go Game Guru readerย Edmund Shaw. Thanks Edmund!

Black’s stones at the bottom still have some life in them. Can you find a move that creates miai?

  1. Grimbold says:

    Nice tesuji on the intermediate problem. That will come in handy in my games. But why is the atari a mistake for white?

    • After the atari black will put pressure on white by threatening the 4 stones and eventually capturing the whole thing.

    • Younggil An says:

      Thanks for your answer Siim.
      Grimbold, you can see the continuation of Black E5 and see why White’s cutting at B3 is a mistake.

    went faster than I was thinkin it will be, made all 3 in less than 2 mins haha, personal record!

  3. Josh Hoak says:

    According to Graded Go Problems for Dan Players Vol 65, Tesuj for 4-7d Players, Problem 2 comes to us from a new move by Kamimura Kunio. Doing a little digging, I found that it was a game between Kamimura Kunio (8p) and Kitamura Hiroshi (7p), 29 Aug 1991.

    Specifically this game: https://badukmovies.com/pro_games/16745-kitamura-hiroshi-kamimura-kunio

    Woo! I knew I read that this problem was from a professional game somewhere. It’s been bugging me ever since.

    • Younggil An says:

      Wow, you have a good memory Josh! ๐Ÿ™‚
      Thanks for sharing the game record.

  4. Thanks for putting up my problem. I hadn’t anticipated how many wrong lines you would analyze, more effort than intended for you! – sorry about that ๐Ÿ™‚

    • Younggil An says:

      Hi Edmund, that’d be alright. David likes your problem and so do I. ๐Ÿ™‚
      David needed to put some wrong lines, but other problems are about the same, so it wouldn’t be a problem for him.

  5. Hi Mr Younggil, do you mind I put the problems from this website to some other website and share them with other go players? Cheers Daniel

    • Younggil An says:

      Hi Daniel, thanks for your question.
      I just talked to David, and he agreed that you can share the problems to others with ‘give credit’, so people can see the problems are from Go Game Guru.

      • Thanks Younggil, I am not too sure what ‘give credit’ mean here. But I will definitely let others know the problems are from Go Game Guru if I put them on any other website.

  6. Ryan Dickman says:

    Im having a problem understanding certain circumstances when I have white surrounded and they take large groups of my stones.

    • Younggil An says:

      That’s normal Ryan. If you read some books about defending and sabaki, that’ll be a help. ๐Ÿ™‚

  7. In problem 2, why not cut first at the 5-5 point and then hane underneath?

    • Younggil An says:

      That’s a good question.
      You can see the continuation from the cutting at 5-5.
      Black can try to fight after White’s last move from that variation, but the position is better for White. That’s why Black doesn’t normally cut at 5-5, but play like the right answer above instead.
