I don't think Otake would like to be described as a 9-dan, and certainly not as a 9p. I'll explain that later, but first a note on his retirement at the age of 79 in December 2021. It made the national press in Japan, after all.
He retired with a win-loss record of 1317-846, plus 5 jigos and 1 void game. This year his record has been 8-9, and last year was 4-7, so he still has what it takes to be even a 9-dan, but his real title was Honorary Gosei. He monopolised that for a time. He also won the Meijin, Oza and Judan titles, but the Kisei and Honinbo escaped him, though he did reach the title match in the Kisei a couple of times. In all he won 50 titles.
His win record of 1317 games made him only the fourth in Japanese history to pass the 1300 mark.
A couple of his games even made it into
Hikaru no Go (GoGoD 1993-02-08a v. Takemiya, and 1996-06-14a v. Cho Chikun). Really, that was a little remiss of the Shonen Jump team. If you want to show the best of Otake you should be showing him against Rin Kaiho, his long-time rival. They are the same age, and at his farewell press conference Otake paid tribute to Rin for making him what he became. He added that he had misgivings about retiring before his old friend. But he said he had thought about his decision for the past few weeks, and what convinced him it was time to go was that he was now seeing, in his mind, pictures of go that just didn't seem right. He put this in a rather cryptic, enigmatic way (図/貧相) that had clearly been prepared so as to make people think. Since most people associate Otake with the aesthetics of go, his audience could fairly be expected to make that link here. Precisely what is meant by the famous "Otake aesthetic" is a matter of debate, however.
He is alleged to have resigned games just for making a bad move. That may be apocryphal. Even talking about his go on the go board may miss the mark a little. He certainly had strong views on good shape. He felt that playing lots of games taught one to recognise lots of positions and how to play them - the neural network approach, of course. When he was learning go as a child he didn't seem to invest too much time in rational thought. Mrs Kitani, in her autobiography recounts that in the Kitani school's evening sessions, when the pupils were supposed to play each other, he would do so with a comic in his hand.
Indeed, although he is associated with katachi (good shape), and even began a well regarded book on lightning go (the only one?) with a chapter on "learning by means of good shape", his introductory remarks in that book showed that he had in mind something that is more like dynamic haengma. This is what he says:
"In lightning go, the most important thing is to have a definite rhythm. If you lose that rhythm your stones will unexpectedly start moving in
the wrong direction. Once you lose the feeling of rhythm, you will end up with the phenomenon where "bad moves call forth more bad moves." Therefore the problem you have to solve is how to maintain this feeling of rhythm. Learning to play in good shape is essential to be able to complete a
whole game in a short time. It also serves by allowing this rhythm to flow naturally to the end. As soon as a certain shape appears on the
board, you need to be able to say: that's where I play now. A typical example is playing hane at the head of two stones. Of course in go there
are no absolutes. You must always look at the surrounding position before deciding whether or not a shape is good."
He then goes on to discuss sabaki, which is not what many westerners think it is. He is at pains to stress that the meaning is simply "coping" or "managing". Again a direct quote which is notable for the absence of the usual western sabaki buzzwords 'light' and 'flexible':
"Sabaki comes from the verb sabaku which means 'to bring things to a successful conclusion' or 'to resolve a confusing situation.'
But in a broader sense his aestheticism seem to derive from a love of Japanese tradition, with a feeling for hierarchy. This involved respect.
He was reportedly appalled by the behaviour of certain western amateurs at a European go congress, arguing about rules. Since he was for several years the President of the Nihon Ki-in, it is no surprise (as I have been told from several sources) that this had an impact on Japanese support for western go, though an unexpected Japanese economic downturn must have played a bigger part.
This (if true) was not xenophobia. A similar sense of what he regarded as right and proper can be seen in a domestic venture: the Meikikai or Distinguished Players Association, formed in 2003 in response to a call by Yoda Norimoto, O Rissei and Kato Masao.
This was an elite (and apparently elitist, to its critics) gathering limited to current pros in the Nihon Ki-in who had held one of the seven major domestic titles at least once. Its ostensible purposes were: (1) to help the spread of professional go; (2) to be a forum for debate on the way forward in professional go; (3) to support moves to make go more popular among the younger generation. The first association president was Otake Hideo, and Rin Kaiho was vice-president. Founder members, whom we might term 'the usual suspects,' totalled 20. Despite the formal articles of association, the real purpose of the association was seen in the press as a way of differentiating the very best players from the run-of-the mill 9-dans. The background at the time was that Japan had 443 professionals of whom 113 were 9-dan (out of a world population of 956 pros: 193 [26 9-dans] in Korea and 298 [20 9-dans] in China). In a phrase, rank inflation. But there was again an economic side to it: pensions were awarded on a rank basis, and the Nihon Ki-in was in the red.
Another clue to his mindset is that in his retirement press conference, he said that he hoped to enjoy life now as in Mito Komon. This was a long-running period drama on Japanese tv in which Mito, a retired merchant, roams around old Japan with two fun-loving samurais, Suke-san and Kaku-san. They right wrongs and take on gangsters while having their fun. (For gangsters I'd be tempted to read rules mavens!)
Mention of Kaku-san reminds me, because his full name is Atsumi Kakunoshin, that Otake also produced a couple of new proverbs. One, which I don't rate highly, is "When in danger, enter the tiger's lair." But I am rather fond of the other one: "When your opponent is thick, you must become thick, too."
Now, to finish, another look at Otakian sabaki.
In the following position, how does Black achieve sabaki? There are two answers, depending on whether ladder breakers work or not.
