The 3rd game of 34th Kio-sen between Kio Sato Yasumitsu and Kubo Toshiaki(8 dan) was held at Niigata Grand Hotel in Niigata City, Nigata prefecture on March 8, 2009. Sato was Sente player. Kubo chose Gokigen Nakabisha and Sato adopted G-7h at the 7th move which seems popular against Gokigen Nakabisha recently. Sato beat Kubo in 121 moves. The score is 1-2 still led by Kubo after the game.
