Kanazawa Solution Three
    Keywords: MiddleGame, EndGame

Authors:

Main line: HashimotoUtaro 9p
Variations: AndreEngels 3D, unkx80 1D*, DieterVerhofstadt 1k



[Diagram]
Diag.: Main line

After 1, making an eye at the circled point, A and B are miai for life.


[Diagram]
Diag.: 2 and 3 are miai (i)

After 3, Black has real eyes at the circled points.


[Diagram]
Diag.: 2 and 3 are miai (ii)

It seems as if White falsens the eye, but the capture of three stones with 5 results in a real eye.


[Diagram]
Diag.: 2 and 3 are miai (ii cont)

Even if white throws in at 6, Black lives with 7.




[Diagram]
Diag.: Variation

If White captures at 2, Black 3 makes a second eye. If Black doen't respond, white A kills the group.



[Diagram]
Diag.: Wrong (i)

The other 1-2 point is again not successful. With 2, Black is left on the spot. Even if allowed to play two moves in a row, he can't live anymore.



[Diagram]
Diag.: Wrong (ii)

When Black plays 1 here, white can choose between A and B to kill Black. Someone an opinion which is the better ?




[Diagram]
Diag.: Wrong (iii)

Also wrong is black 1 here. White 2 and 4 leave A and B miai for the kill.



[Diagram]
Diag.: Variation

Making the eye as large as possible with black 1 here, seems to be correct as well, but it is not the solution from the book. After white 2, black 3 follows, and black lives as shown. White 3 is followed by black 2, white A, black 7. White 7 is answered by black 3. White 4, black 7. White 5, black 4.


[Diagram]
Diag.: Variation (2 at 1-2 point)

If Black 1 is a mistake, then it must be because White can next play at 2. If Black now plays 3, white 4 kills the entire black group. But ...


[Diagram]
Diag.: First try

... when Black throws in at 3, White fails.


The authors of the variations shown here, have not yet found the reason why 1 in the main line is preferred to 1 here.
