-Kungfu

--Dieter: Well, I have to check the problem book again. Even simply descending to 3 immediately saves the group. It feels as if there is a superfluous stone, probably the marked one, as unkx80 indicated. My apologies if it turns out to be so.

Diag.: Solution?

Diag.: Variation 1.

[Diagram]
Diag.: Variation 2 (Main Line).

The next tesuji is White 3, sacrificing yet another stone.


[Diagram]
Diag.: Variation 2a.

Diag.: Variation 2b.

Diag.: Variation 2c.
