Iyama Yuta

Iyama Yuta 9p is the #1 player in Japan. He currently holds five of the seven major Japanese titles, and he’s become practically unbeatable in his country.

Since he’s been very busy playing in many domestic title matches, he’s missed out on participating in international matches quite a bit, but he managed to join this time.

He defeated Zhang Tao 3p, from China, in the round of 32, and many Japanese Go fans want to see him go further in the international tournaments.

Lee Younggu

Lee Younggu 9p is currently #14 in Korea. He won the 7th Price Information Cup in 2011 and it was his first title. He hasn’t won any other titles since then.

He was lucky to be able to join this year’s LG Cup as a replacement for Won Seongjin 9p, who’s currently in the navy completing compulsory military service.

Lee beat Xiao Zhenghao 8p, who was the only representative from Taiwan, in the round of 32.

This is their first official match together, but they once played at the international rookies’ matches in 2007. Lee Younggu won at that time, but it was a quite a while ago.

  1. Fantastic! I always appreciate your commented games. They’ve been a great help and are very entertaining.

    If you’re still doing older games every now and then, I would be very interested in some of Takagawa Kaku’s games. I’ve heard a lot about his style but his uncommented games are still beyond me.

      Thank you for the comment.
      I’ll consider of reviewing one of his games. ๐Ÿ™‚

  2. Great commentary as always, and thanks for exploring the alternative plays too – great to get so much insight where the reading is too deep for an amateur like me!

  3. Thanks a lots ^^

    Great review! It is nice to see how a professional baduk player looks at the game. Thank you!

  5. Very interesting, thank you very much. I too like the guessing game with the alternatives, using this medium to the utmost.

    Kind regards,

  6. Paul, there wasn’t a guessing game there. 1 was always the next move and 2 was usually an alternative move it seems.

    • David Ormerod says:

      Did you guess the times when move 2 was actually the better move though? ๐Ÿ™‚

  7. Great commentary! Thanks!

    Beautiful comment, as usual. Pro games doesn’t look anymore like egyptian hyeroglifs or chinese ideograms ๐Ÿ™‚
    A. One remark: english is simple, but most of the readers not native english. So… do not make verbs like ‘ to tenuki, he tenukies’, or ‘to hane, he hanes’. Keep it simple, he tenuki, he hane.
    B. Dear sensei, what was the victory we like most ? And the worst defeat ? Could we see these games ? With some comments, if possible.
    Bye from Romania

    P.S. I recommended your wonderful site to some hundred players on KGS

  14. It would be helpful if you could make .sgf downloadable for iPhone. Great commentary, thanks.

    • David Ormerod says:

      Hi Joe, the .sgf files are downloadable for iOS. Just click the link to the file where it says ‘Download SGF’ in the lower right. You need to install an app like SmartGo to be able to open them though.

      Some readers have told me that they can’t open the files on their iOS device, because it makes Safari crash. This seems to be an issue with certain versions of Safari (possibly related to their implementation of JavaScript). It always used to work in older versions, since all it is, is clicking on a link to a file and downloading it in a normal way.

      We’ve setup the mime type properly for .sgf on our server and tested various other things to try to fix iOS downloads for people. It seems that there’s nothing else we can do to fix it. This is a problem with Safari and it has to be fixed by Apple.

      Maybe you and other iOS users should let them know?

  15. Thank you for this beautiful commented game!

  16. As always, an awesome commentary, very enlightning.

    Please, please continue ! And older games are also very interesting, don’t hesitate to go back to the past as well.

    Best regards and many thanks again.
