Hikaru No Go Problems
   

The Sensei collective doesn't read Hikaru no go for the pictures, the plot twists, the charming personalities... no, not even for the cute little wrinkle in Akari's cheeks when she smiles. They read it for

The Problems

HolIgor: I've never read any manga or comic strips. But this one is about go and people liked to discuss it. So, I've downloaded some. It is quite interesting and there is go there too. Umezawa Yukari does her work.

Hikaru - Problem 1

So, here is a problem that Sai solved at a glance provoking Hikaru's remark That spoiled a game in children's tournament.

DaveSigaty: I have altered the diagram so that it matches the drawing in the manga. The original was somewhat different.

Diag.: Black first

Comments were that even a pro would take time to solve it. No solution is given, of course.

Those who read the manga know the first move in the solution, but do they see the implications?

So I open the discussion of the problem

The problem is also discussed at KanazawaSolution75. The move is White 5 in the main line.



Hikaru - Problem 2

The problem is from chapter 7.

Diag.: Black first

Solution



Hikaru - Problem 3

Also from chapter 7.

[Diagram]
Diag.: Black first

Solution



Hikaru - Problem 4

Still from chapter 7.

[Diagram]
Diag.: Black first

Solution



Hikaru - Problem 5

This one comes from chapter 19.

[Diagram]
Diag.: Black to live or White to kill

Solution



Hikaru - Problem 6

[Diagram]
Diag.: "I want to improve!"

This is not a formal problem but is interesting. In chapter 61 Hikaru and Sai are playing a teaching game. Hikaru has been inspired by his recent game and is talking about how much he wants to get stronger. In the midst of this Hikaru plays 1. Sai is thinking about what Hikaru has just said and criticizes this play.

Where should a student professional (or any student?) play instead of 1? Why?
Solution



Hikaru - Problem 7

[Diagram]
Diag.: Pro Exam - Black Goes Next

This game appears in chapters 90/91. Hikaru takes black here and his lower right corner is apparently in trouble. Can black live? Hint: the hero of the manga is Hikaru, so the answer to this question is pretty obvious. :) The more interesting part is how.

DaveSigaty: If you're too lazy to figure out this simple problem for yourself :-), the original game is now identified and linked on Hikaru No Go Games.
The game was the subject of a special game commentary in Go World no. 22 which includes the following statement at this point in the game:
"The following commentary is presented more for entertainment than for edification. The game becomes so complicated that a definitive analysis is beyond the present level of professional skill. The main points to emerge from the post-game analysis are given, but the conclusions are necessarily tentative."
