Hikaru's comment

    Keywords: Culture & History

This article is about a game in the anime and manga series Hikaru no Go. Two characters, Toya Meijin (the meijin in the series, real name Koyo Toya) and Fujiwara-no-Sai are playing a Go game. Hikaru Shindo, the protagonist, is placing the stones down for Sai, who is a spirit. Hikaru makes a comment regarding one of Toya Meijin's moves.


JonatanLindstrom: When Sai's game against Touya Meijin is finished (chapter 116) Hikaru comments one of Touya's moves. Could any one please comment the comment? :-)

HolIgor: As I remember, I have to check with the game though, Toya Meijin had a placement tesuji in the left top corner that allowed him to skip connection and thus win the game. But I did not read that out.

JonatanLindstrom: Hikaru is speaking about move #181 (the [ext] game is really between Yoda Norimoto (White) and Rin Kaiho played on 1997-05-01 during the 22nd Meijin League).

move #181  

Hikaru says: "If he had placed a stone in the corner over here..." (we can't see where he is pointing) "White is forced to protect"

Where is "here", and what happens next?

Robert Pauli: In the game White kind of protected at circle, but to me the corner seems save without: enough outside liberties to sqeeze . . . Was circle just a big yose?


Vesa: My theory...corrected

variation for #181  

Black scores points compared to the game.

Later approximately 7 points endgame  

Tas: I still don't understand this. Could someone please elaborate? And what are the further suroundings? are all outside stones alive?

Zelda91:(hypothesis) It's not seki, so if you want to kill the stones you must get rid of all ko threats first, I suppose that what is meant, so it's a tesuji forcing him to play connected on the whole board which is a sacrifice of pts. I suppose the particular shape of the game made it a very solid in connections type. So no threats are avoided: more pts are scored.

standardtrickyness?: the critical thing is that without S15 (see game) white has to answer T17 with T16 then if black tenuki locally white plays at T18 relative to if white plays S15 first then if black T17 white T16 and we can see although the same number of moves have been played on each side in the game variation white is 1 pt ahead @zelda91 I don't think that was the main point in the difference of move order just the one point difference if white responds locally its no that significant if the game was not close.


anonymous: The real life game which was used in the manga and anime was a game from the 22nd Meijin League between Rin Kaiho 9p (Black) and Yoda Norimoto 9p (white), played May 1, 1997. You can see the whole game [ext] here and it was close, White (Yoda) won by a half point.

standard trickyness? to elaborate if white responds to black T17 with S15 then whites liberties are not enough to squeeze when black plays T18 so white will respond with T16 but this move does not work well with S15 so Robert S15 is quite an important yose as it allows white to respond to T7 with T16 so white can keep the corner regardless of outside liberties ps anyone want to tell me how to include my name into edits automatically?

anonymous: The game record was published in the Nihon Ki-in yearbook issued in 1998. There are very brief comments with no illustrating diagrams but maybe there is some interest because there are comments on some other moves in addition the one Hikaru commented on. The commentator is not named. Here they are: "White 12 is a new move. Black 19 is a little kikasare(pushed around). Black 33 is dubious; there is no good ladder breaker. Black 39 is a popular move in Korea. Black 59 is a bad move. The moves following Black 99 are reasonable. After Black 101 it is a close game. Finally, if Black 223 had been at the 224 point Black would have won by a half point."
