The 41st Tengen final, game 3 was played on November 25, 2015 in Fukuoka, Japan, and Iyama Yuta won by resignation at 147 moves.
Return match of Tengen
In 2014, Takao Shinji challenged for the 40th Tengen, and he defeated Iyama Yuta with a 3-2 score to become a new Tengen.
However, Takao didn’t succeed to defend Tengen title against Iyama.
This year, Iyama Yuta defeated Yuki Satoshi 9p at the challenger deciding match, and he became a challenger.
Game one of the final, Iyama built a big moyo over the center for Black, and White invaded. Black attacked White’s invading stones fiercely, and there was a serious capturing race in the center.
Unfortunately for White, Black had one more liberty to win the race, and the game was over at the same time.
In game two, the opening was relatively peaceful, but Iyama started to play aggressively after he failed fighting at the top.
Takao (Black) was clearly ahead up to 81, and Black maintained his lead until the end of middle game.
However, Black 149 was a crucial mistake, and White caught up through to 180. The game was still very close, but Iyama showed his special technique, and he won the game by half a point.
In game three, Takao seemed to lose his fighting spirit after losing his won game in game two. Iyama showed his power through the game, and he captured White’s huge group to finish the series.
Iyama had held Tengen for three years from 2011 to 2013, so this was his forth Tengen title.
Another return match of Oza
Meanwhile, there was another title match played between Iyama Yuta 9p and Murakawa Daisuke 8p.
That was very surprising and sensational, because it was the first time that Iyama lost to a younger player than him in the final match.
This year, Iyama defeated Yo Seiki (Taiwanese name Yu Zhengqi) 7p at the challenger deciding match, and he became a challenger for another return match of 63rd Oza.
Game one of the final was very exciting with a whole board fighting. Murakawa (White) took the lead at the fighting on the left side, and he was leading in the middle game.
However, White 140 was careless, and Black 141 to 145 were exquisite sequence to help his left side group, and his left side group lived in sente up to White 150.
Black’s sequence from Black 151 to 165 was bold and severe, and Black caught up through a big trade up to White 172.
The game was very close, but Iyama managed to win by half a point, and that was a painful defeat for Murakawa.
After losing game one, Murakawa appeared to be too disappointed, and he didn’t show his strength next two games.
Iyama won game two and three relatively easily, and he returned to Oza with a 3-0 score on November 19, 2015.
He had held the Oza in 2012 and 2013, so this was his third Oza title.
Iyama Yuta’s ambitions
Judan is the only title which is out of reach from Iyama Yuta, and Ida Atsushi 8p defeated Takao Shinji 9p to become a new Judan in April, 2015.
So far, he is proceeded to the semifinals of the 54th Judan, and is going to play against Imamura Toshiya 9p next.
It will be interesting to see if or not Iyama’s dreams of achieving the gland slam of Japanese Go, by claiming all seven major titles simultaneously will come true in 2016.
