This is the 5th game of the 67th Honinbo final between Yamashita Keigo 9p and Iyama Yuta 9p.
In this series Yamashita is the Honinbo title holder and Iyama is the challenger.
Iyama won the first two games, but Yamashita won the next two. So this is a very important game in the series.
Yamashita Keigo
Yamashita was well known for his very creative and bold openings when he was young. He likes fighting and complicated games.
Iyama Yuta
On the other hand, Iyama’s style of play is thick and solid.
He beat Lee Sedol and Gu Li at the 1st Bosai Cup in 2011, and lots of Go fans from China and Korea were shocked.
He’s a top player in Japan and he’s still quite young. He’s the future hope for Japanese Go.





Beautiful game, thank you for the enlightening comments and choices to make. But Yamashita must have felt awful. Is it exhaustion after being in time trouble for a long time?
Kind regards,
Paul
Hi, isn’t the comment on move 40 a typo; shouldn’t it be “later, white might answer A with C (some other move — descending or something?”.
Also, I looked at Iyama Yuta’s records, and he’s doing really great, with the Honinbo and Tengen, and just one game from taking the Gosei, but what about the recent Kisei League game where he barely won against Awaji Shuzo by 0.5 point? Who is Awaji Shuzo? A really good player or did Iyama just have a bad day (I haven’t played over the game yet)?
Yes, you’re right. There should be C for the answer at C6.
Thanks.
Great commentary, again!
mistakes…
Deep and interesting game. Long time controls rule, as do your game commentaries, An =)
Nice game! Thanks for the commentaries! =D
It is a pity that Yamashita Keigo played wrong in the end. =(
Thanks a lot Mr. Younggil. Very instructive comments.
Thanks for the commentary! It’s wonderful to get this kind of analysis on current games.

Fantastic commentary, thanks! Amazing how such a deep game can change so quickly with a single slip.
