      Thanks for your commentary on the 5th and 7th games of this series.Very helpful to my efforts to understand them. To me the whole match had the feeling of both players competing to their utmost. Very exciting. I was already a fan of Iyama’s but this match left me with an interest in Yamashita also.

  2. Thx very much!

    It is funny how i completely missjudged the situation first time i looked at the game. I really thought the result after b’s ponnuki was quiet good for him, and that w did magic after that^^

    Still many things were very complicated in the fighting, and the explanations are really of great help.

    I really enjoy the commentaries and the website very much, thx for all the effort

  3. FYI: I’m getting an error
    “There was a problem retrieving the game data.”
    Is it my computer or is there a problem with the website?

    • David Ormerod says:

      The server was unstable for about an hour a few days ago. I think that’s what caused the problem for you Martin. It should be ok now, but please let me know if you’re still having problems.

    • Same problem…. the last few weeks the download button does nothing!
      I like to review these in my own sgf readers on both my Linux and Windows machines.

      • David Ormerod says:

        That’s a different problem Majid and I’m not able to replicate it at my end. Have you tried clicking the link that says [link] to the lower left of the game? Does that work?

        • That wotks for me but its not clear that is what you should use for getting pdf’s. But thanks for doing a great job overall.

    It’s always a joy to read Younggil’s detailed game commentaries. I also want to thank him for the effort he puts into them 
    I remember discussing this game with a friend (tygem 9d) a week ago, and he said Black made some mistakes in the bottom-right corner fight. For instance, would Black S6 instead of R5 (move 127) be better? Also, a couple of moves later, he suggested Black N5 instead of O6 (move 129). What does An Younggil think about this? Thanks very much!

    • An Younggil 8p says:

      Thank you for your ideas.
      S6 instead of R5 could be also possible. There should be lots of variations, so I can’t say which one is better. If black plays at N5 instead of )6, white can play at S5 to connect, and it’s also complicated. There should be so many possible ways, so it’s pretty hard to discuss about those moves.

      • DanielTom says:

        If Black N5 instead of O6, and White answers S5, then Black S6, White Q5, Black Q4, White S4, and Black T7. Does that tesuji work?

        • An Younggil 8p says:

          Yes, you’re right, That tesuji works well. 🙂 Then white would play at O8, and it’s still very complicated. Black needs to play one more move on the right side, and white’s corner is not yet captured.

  5. Always interesting to read this sort of detailed analysis. I thought that B must be doing well after making the ponnuki in the lower left but W was able to erase so much. Shows that my positional judgement is not so good. It is amazing that W was able to make so much out of the top left corner, a position I would not have thought capable of that much complexity.

  6. Thanks for these two games comments. You are always making the pro games more and more understandable to all of us.

  7. Thanks for these comments. So happy Iyama Yuuta avenged Hane Naoki.

  8. Super game, super explanation: thank you very much!

  9. Fantastic commentary! I really appreciate it.

  10. move 8 is from the 40th Kitani and Hashimoto Utaro played this and also patterns which come back as new joseki these days^^
