It was played at the Nihon Ki-in Kansai branch in Osaka, on August 23, 2013.
Iyama Yuta is the #1 player in Japan, and he’s also Japan’s greatest hope on the international Go scene.
He challenged for the Gosei last year, and defeated Hane Naoki 9p 3-0 in the final to take the Gosei title.
Therefore, this final was his first time defending the Gosei.
Kono Rin 9p was born in 1981, and he became a pro in 1996.
He defended the Tengen title for the two following years, defeating Yamashita Keigo 9p in 2006 and 2007.
He also won the 29th NEC Cup in 2010, and he recently challenged Iyama Yuta to reclaim the Tengen title (2012), but was defeated 3-0.
This final was seen as a kind of grudge match for Kono Rin, and he won the first two games with his powerful style of play. However, Iyama won the next two games, making it a tie.
This final game would decide the best of five Gosei title match.
In general, we’d expect Iyama to have the psychological advantage going into this final game, because he was in good form and was on a winning streak.
Let’s have a look at the final game of the 38th Gosei title match.
The time limit was 3 hours and 5 x 1 minute byo-yomi each.
