Iyama defends Oza and Tengen titles: Everything is going well for Iyama Yuta these days, both internationally and domestically. In quick succession, he defended two of his top-seven titles, making sure he ends the year with his Grand Slam intact.

2017.11.26_Oza 3 IrikiOn November 20, the third game of the 65th Oza title match was held at the same venue as the second game (on the 18th, covered in my previous report, published on the 21st), that is, at the Hotel Okura Kobe in Kobe City, Hyogo Prefecture. My description of the second game needs to be revised in light of the Go Weekly report. Apparently Ichiriki (white, at left) took the lead in the opening and in the middle game he built a winning position. However, Iyama made a do-or-die attack that ended in his capturing a large group and pulling off an upset. In the third game, in contrast, it was Iyama (white) who got a good position in the opening (mainly because Ichiriki was burdened with a heavy group). In the middle game, he kept up the pressure on Ichiriki and forced him to resign after 174 moves. This gave him a 3-0 lead, so he defended his title. It is his third Oza title in a row. One rest day may not have been enough for Ichiriki to recover from the shock of letting slip the second game. The fourth game was scheduled to be played in his hometown of Sendai, but he couldn’t take the match that far. The Oza prize is 14 million yen (about $127,000).

The third game of the 43rd Tengen title match was played at the Munakata Yurikkusu, an entertainment/sports/cultural complex in 2017.11.26_oza3 Iyama rightMunakata City, Fukuoka Prefecture, on November 24. Playing black, Iyama (right) built central influence in the opening, but Ichiriki attacked his centre group and tried to blockade it. In response, Iyama cut the blockading group into two and tried to surround the centre part of it. Ichiriki came up with a clever answer, so his group was able to break out, but in the subsequent fighting he missed the best sequence. After that, the game went downhill for him. Iyama set up and won two successive ko fights, also killing a white group in the second fight. Ichiriki resigned after Black 171. Iyama’s fighting ability gave him the edge over the challenger. This win made the score 3-0, so he 2017.11.26_tengen3 IchirikiJPGcompleted his Tengen defence just four days after his Oza success. Finishing off both these titles so quickly earns Iyama a lot of extra time for rest and recuperation in December.

Iyama: “In this series, each game could easily have gone either way. I think that in the end I was just lucky.”

Ichiriki (left): “In both the Tengen and Oza matches, I felt a gap between Iyama and me when byo-yomi started.”

The Tengen prize money is 13 million yen (about $118,000). Iyama has now won 48 titles, so he has moved ahead of Kato Masao into equal fourth place with Otake Hideo. It will take him a while to overhaul the players still ahead of him: Kobayashi with 60, Sakata Eio with 64, and Cho Chikun with 74.

Starting with the third game in last year’s Tengen title match, Ichiriki has now lost nine games in a row to Iyama. He has just over seven weeks to regroup before the Kisei title match starts. First of all, he will have to adjust to two-day games.
