Go Commentary: Iyama Yuta vs Hane Naoki – 37th Gosei – Game 3

This is the third game of the 37th Gosei final in Japan, between Iyama Yuta 9p and Hane Naoki 9p.

Iyama won the first two games, so if Hane Naoki loses this game, he’ll lose the Gosei title (the Gosei is a best of five title match).

Hane Naoki (9 dan, left) and Iyama Yuta (9 dan) review the third game of the 37th Gosei title match.

Hane Naoki

Hane’s style of play is gentle and calm. He prefers to play a long territorial game.

Iyama Yuta

On the other hand, Iyama prefers a fighting game, as he’s confident at fighting and still quite young. In general, younger players tend to be keener on fighting.

Iyama won the Honinbo title, defeating Yamashita Keigo, just four days before this game.

Let’s have a look at the game, and if you have any questions, please feel free to leave a comment below.

  1. very good review! thanks a lot!

  2. Bawannoboy says:

    Really interesting. Thanks a lot !

  3. Great commentary and a very impressive game. Iyama seems to be doing really well with both the Honinbo and Gosei titles. It will be interesting to see where he goes from here.

  4. Thanks a lot for the comments. Very good game for learning.

  5. It seems that Iyama is dominating Japan at the moment; he’s already eclipsed the “second rank” of Japanese players and is doing very well against Yamashita and Cho as well. Honestly, this match against Hane looked like a total domination (three straight games by resignation).

    An, how strong do you think Iyama is, in relation to the current top Korean and Chinese players? Do you think there’s a chance we can see him play more international matches in the near future?

      I’m not sure. Just a few days ago, Iyama lost against Kim Hyunchan, a Korean player, and it was quite shocking. It’s because Kim is not a top player, but Iyama didn’t show his talent in that game.
      We should wait and see.

  6. Thanks! Lots of neat little things in this game.

  7. I hope he wins all 7 title tournament in Japan. It will be more interesting.

    • He didn’t win the right to challenge for the Meijin, because Hane beat him in the league play-off. Of course, he already held that title, and lost it 3-4 to Yamashita.

  8. You’re an amazing teacher. When you analyze the situation in these game commentaries, Go seems much easier all of the sudden. But then I play a game by myself and I realize that it’s really difficult again, haha. I hope you enjoy commenting these games as much as all of us love reading them! Thank you very much for all of your work.
