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,
and 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 result. The 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 was 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.

Crazy Stone wins computer go tournament: The 8th UEC Cup Computer Go Tournament was held at the Electrical Communications University in Chofu City in Tokyo on March 14 and 15 with 22 programs competing. In the preliminary tournament, the programs that  won the 6th and 7th cups, Crazy Stone (developed by Remy Coulom of France) and Zen (developed by Team DepZen of Japan) took first and second place in the seven-round Swiss System preliminary tournament, but Zen suffered an upset loss in the quarterfinals of the knock-out stage. Zen is rated 5- or 6-dan on KGS, but it lost to Nomitan, a Japanese program rated as 2- or 3-dan on KGS. In the final, Crazy Stone beat DolBaram, a Korean program developed by Lim Jae-bum. Two commemorative games were played with Cho Chikun (25th Honinbo Chikun) on March 17. Taking four stones, DolBaram won, but on three stones Zen lost.
