  Difficulty: Advanced   Keywords: Problem, Life & Death

Main line: HashimotoUtaro
Variations: Dieter

[Diagram]
Diag.: Main line

A and B are miai for life.

Related proverb: Strange Things Happen At The One Two Point - in this case you need to know which of the 2 one-two points, of course.


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

Black has two sure eyes at A and B.


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

If white next blocks at A, Black makes a big eye at B. And if White draws out at B, Black enlarges the eye with A. Caution: if white has a stone on one of the encircled points, her move at B suddenly works and Black is dead, although a lot of aji remains, because he can break out into the centre (in this position).



[Diagram]
Diag.: Wrong (i)

Black 1 is wrong. After 2, Black 3 and 5 seem to make the most of it, but when White cuts at 6 it's all over.



[Diagram]
Diag.: Wrong (ii)

If black plays at the other 1-2 point, it is also wrong. 5 and 6 are miai for the kill. After white 6, Black can't play at A nor B because of damezumari.



[Diagram]
Diag.: Wrong (iii)

Black 1 here is also wrong. White can even respond at ease to the hanes at 3 and 5, because whatever Black does, A and B remain miai for the kill.



[Diagram]
Diag.: Wrong (iv)

Finally, what about making the corner EyeSpace as big as possible, with 1 here ? White hanes at 2, threatening to capture three stones. Black has to make a solid connection. This is as in KanazawaProblemOne, but with a White stone at 2, and Black is dead.
