Main line: Hashimoto Utaro
Variations: Dieter

Diag.: Main line

Black starts at the 1-2 point. Usually, White keeps this shape to one eye, but here there is aji in the marked stone. The key move is Black 5. After Black 7, Black can either capture four stones in damezumari at 'a' or make two eyes at 'b'.

Diag.: Variation at 6


Failures

[Diagram]
Diag.: Failure at 1

Due to the marked white stone, Black 1 doesn't work. 3 and 4 are miai, and so are 'a' and 'b'.



[Diagram]
Diag.: Failure at 5

If Black 5 here, White falsens his eye with 6.

Diag.: Failure at 5

7 and 8 are miai to take the eye away.


[Diagram]
Diag.: Failure (ii) at 5

Black 5 here is not forcing enough on White's four stones. White takes the time to create a killing shape with 6. (unkx80 has written specifically about this shape at two by three box)
