Ida fights back in Judan: 
Ida Atsushi 8P suffered some setbacks recently but he also won his first open title, as detailed in our last report,
2015.03.29_Takao-Shinji-9pand he seems to be taking his cue from
 the latter. In the second game of the 53rd Judan title, Ida (W) defeated Takao Shinji Judan (left) by resignation after 220 moves, so he has evened the score in the match at 1-1. Takao fell behind when he missed the best move in a fight: he read a variation out correctly for 17 moves but hallucinated about the resultThe game was played on March 26 at the Old Tanaka Family Residence in Kawaguchi City, Saitama Prefecture. This is a three-story Western-style brick house built during the Taisho period (1912-26), with a Japanese-style building, tea house and garden being added later. The whole complex was designated a Nationally Registered Tangible Cultural Asset in 2006. The game was played in the teahouse. The third game will be played on April 9.

Yamashita keeps sole lead in Honinbo League: The last game of the sixth round in the 70th Honinbo League 2015.03.29_yamashitawas played on March 26. Yamashita Keigo 9P (B, right) beat Ryu Shikun 9P by resignation. He improved his score to 5-1 and hung on to the sole lead. All the games in the final round will be played on April 2. Two other players, Ida Atsushi 8P and Cho U 9P, are on 4-2 and so still have a chance of winning the league. Cho U plays Yamashita in the final round; if Yamashita wins, he becomes the challenger; if Cho wins, he will be tied with Yamashita and could meet him in a play-off. The word is “could,” because if Ida wins his final game against Yo Seiki 7P, creating a three-way tie, only the top two-ranked players qualify for a play-off, which would mean Ida and Yamashita. If a play-off is necessary, it will be held on April 6.
