Kato Masao vs Cho Chikun in the 14 th Judan, ther result of this game was void, due to triple ko occur. They replayed the game and Kato sensei won the game, along with the title
Two books had been written by Kato Masao and available in English. Chinese Opening: The Sure-Win Strategy and Kato's Attack and Kill.
Kato sensei's favorite opening was the Chinese fuseki. He played the fuseki a lot.His last game against Yuki Satoshi (who was that year's Kisei challanger) in the 31st Japanese Tengen tournament was a very good example of how to use Chinese fuseki to attack and kill. His next opponent in Tengen tournament was Imamura Toshiya 9-dan. Unfortunately, the game would never been played.
Kato died on december 30, 2004. The cause was cerebral infection. Kato first signs of becoming ill showed on december 7. There were an operation performed on December 10 and was said to be successfull, but in December 28, his condition dropped and he died two days later. At that time, he was member of Japan team at the Nong Shim Cup and hadn't played yet.
Kato was one of 1,200 wins club's member, with a 1,253 win and 664 loss. Only few players can achieve 1200 win.. There are many dedication to him, including a large book published by Nihon Ki-in containing over 200 games of him. Another one is internet Go tournament dedicated to him.
Despite his success, he was modest, his typical manner was low-key and friendly, but also known for his firm principles, which was perhaps the reason why he was entrusted as the Chairman of Nihon Ki-in and the President of IGF.Kobayashi Koichi commented that Kato Masao showed a great fighting spirit inside and outside the Goban (Go board).
I think, many things can be learned from Kato sensei. His fighting spirit, both at his Go life and his personal character, a good character, and his responsibility as a Chairman (he really did what he must did!).
Thank you Kato Masao. You've left us not only your priceless kifu, but also something we must learn about. Two thumbs up for you.
