Masao Sugiuchi 9-dan was born in 1920; he is 96 years old. He is a famous player, who had the nickname, 'the god of Go' (from Wikipedia).
A few years ago, someone said to me: 'Sugiuchi Sensei always uses the stairs when he had a game at the Nihon Ki-in.' That made me think and since then I try to use the stairs as much as possible. On the morning of this game, too, I saw him walking briskly along the first floor of the Nihon Ki-in and he headed without hesitation for the stairs. (Our game was on the 6th floor.)
As we faced each other over the Go board before the game, he said to me: 'Ms. Osawa, you've made instruction trips overseas, haven't you? Where did you go?' In the few minutes before the game started, he talked quite a lot with me.
I was surprised that he knew I had been overseas to teach and I enjoyed our conversation very much.

In the opening, Sugiuchi Sensei played his favourite Chinese Opening. He spent almost no time on his moves.
After Black forced with 15, he made a youthful, flexible attack with 17, and the game developed satisfactorily for him, with Black taking territory while attacking.

Next, White expanded the left side on a large scale with 40 on, strengthened its core with 62, and secured a large territory on the left side. The game was even or slightly favourable for White.
Then Black made a severe follow-up attack with 63.
White played on the vital point with 80, dodging Black's attack. Just at the moment I thought I had captured Black's group, I made a major blunder with 84!!
Black 85 was a marvellous move that combined rescuing the group with a capture. I was full of shock for a while (for more than 30 minutes), but I was also impressed.
Somehow I pulled myself together and defended with 86, but when Black linked with 87 and captured the four white stones in the centre, the game was no good for White.
If I had simply played White 84 at A, putting two stones in atari, I would have been able to capture either two stones (Black 45 and 47) or four stones (Black 63, 65, 15, 73) for free and that would have been decisive.

I knew that A was good, but it's a little bad style, and I facilely thought that the good-style move of 84 would give the same result, but this was awful. A difference of one line is a difference of 20 points.
There were two pieces of chocolate laid out, but when I chose the more delicious-looking one with the better shape, for some reason there was a poisonous toadstool inside! That's what the shock felt like . . .
After that, I felt like I was dying, but the game entered the endgame; though close, White was losing by a little.
In answer to White 122, Black chose 123, which gains two points, but the corner becomes thin and an attack became possible, so White ended up in the lead.
Apparently Black would have won by a little if he had played 123 at C.
I was very happy to have this chance to play Sugiuchi Sensei.
I will also make it my goal to be able to play youthful moves that move people no matter what my age is.
Everyone, how about using the stairs when you go to play Go?
