Honinbo League: The fourth round of the 74th Honinbo League has been completed. Instead of one player breaking clear, the position has become complicated, with four players sharing the lead. On January 7, Yamashita Keigo 9P (W) beat Anzai Nobuaki 7P by half a point. That improved Yamashita’s score to 2-2, so he is still in the running to win the league (he’s also helped by his number one ranking). Anzai goes to 0-4, so he looks unlikely to retain his league seat. However, the narrow margin shows that he is not being outclassed. In the second game, played on January 10, Yo Seiki 8P (B) beat Hane Naoki 9P by resig. Yo and Hane are now both on 3-1. The only undefeated player at this point was Ichiriki Ryo 8P, who was on 3-0. On January 17, he played Shibano Toramaru 7P; taking white, the latter beat him by resignation, so both went to 3-1. On the same day, Kono Rin 9P (W) beat Ko Iso 8P by resignation. Kono improved to 2-2, but Ko went down to 0-4. Ko also looks like losing his place, but being ranked number two gives him a slight advantage over Anzai.
Meijin League: Two games in the second round of the 44thMeijin League were played on January 10. Kono Rin 9P (B) beat
Mutsuura Yuta 7P by resig. and Shibano Toramaru 7P (W) beat Murakawa Daisuke 8P by 2.5 points. Two more games were played on January 17, and one of them could have a big effect on the league. Suzuki Shinji 7P (B) beat the favorite, Iyama Yuta, by half a point. In the other game, Son Makoto 7P (W) beat Hane Naoki 9P by resignation. On 2-0, Kono is the provisional leader.
Judan challenger: Murakawa or Takao: The first semifinal of the 57th Judan tournament was played on December 27, with Takao Shinji 9P (W) beating Yamashita Keigo 9P by 2.5 points. The second was held on January 7. Murakawa Daisuke 8P (W) beat Onishi Ryuhei 4P by resig.
