Kyo Kagen 7 dan won the first game of his Gosei title challenge against Iyama.

Given how many times black tenukied on his center group, I'd say it is only justice it died

[Uberdude]

Kyo Kagen / Hsu Chiayuan 7p beat Iyama in the 2nd game of the Gosei today, by 1.5 points as black. New generation finally catching up?

Comparing to the Honinbo games with Yamashita, the fighting ended much earlier here (big fight ended and large endgame started around move 110), so if Iyama is better at fighting in time pressure than Kyo like he is vs Yamashita then Kyo avoided allowing Iyama to benefit from this.

Iyama will face Cho U, who was top dog of the Japanese Go scene in the mid 2000s before Iyama's dominance and is having some better results recently, in the Meijin title match. First game is 28th August.

Looks like a revisit to their 2008 and 2009 matches...

Yup, Cho defended his Meijin against Iyama in 2008, but lost it in 2009. I believe the last title match between them was 2013 when Iyama won the Kisei for the first time (and the last of the big 7 for him to win).

Game 3 of the Gosei is now live on youtube.

The game so far with some LZ comments, the general trend seems to be Iyama plays slightly better, but made 2 big mistakes (allowing squeeze, and not keeping dead stones dead after a trade).

Things seem quite tedious now in the last open area of the board.

And Kyo wins! Iyama sacrificed (or Kyo killed) his top stones in exchange for the attack on white's bottom left, but that remained a ko (so LZ's judgement black should have kept the dead stones dead for security seems validated by the course of the game), white lived in ko there in exchange for black getting 2 moves (and ko threat removal) on his big centre though bottom side moyo, but white made nice sabaki within and cut it down to size and won by resign. So Iyama loses his septuple crown.

He did hold it for about 291 days and 40 minutes .

I believe it's the first time Iyama has been swept. In every other match, he scored at least two wins.

2016 Meijin: 4-3
2008 Meijin: 4-3
2014 Oza: 3-2
2011 Kisei: 4-2
2014 Tengen: 4-2
2013 Judan: 3-2

Did he hold all the titles only for one year ? Not for two years ?

[hyperpape]

He's held the septuple crown twice. The first time he held it for about half a year in 2016, but lost the 2016 Meijin to Takao. Both spans were less than a full year.

Sorry, 289 days and 59 minutes.
