Tsumego From Games 32 Attempts
   

Hans: This seems to be difficult. My guess: Since white cannot win the fight at the top she has to try something in the center. I am not sure about the order of moves. Besides there may be other black moves to capture white. If black insists in capturing white at the end there is a big seki.

Attempt Part 1

Dieter: B6-W7 is too much of an assumption (see below)


[Diagram]
Attempt Part 2 - Seki

White's stones around 7 have to run away and there remains the cutting point marked with a circle.



Dieter: Very interesting. It all depends on the outside of course, but seki indeed seems to be the main line.

[Diagram]

W1 is clearly sente to save stones, but W3 isn't: a and b are miai.


[Diagram]

If we assume W3 here to be sente, B6 or a (see below) is a better response than the one given above.


[Diagram]

The end result is seki.


[Diagram]

W3 is sente.


[Diagram]

If Black B1 here, it turns into seki again.



Hans: Nice analysis, Dieter. I do not have the time at the moment but for a complete solution one must prove that white cannot do anything at the top.

4 fills in at 1

This is the way we saw it at the club after the game... If black doesn't capture the throw in at 1, then white can atari at 6 and then connect. -- Snappy

unkx80: I don't have time to do detailed analysis right now, but doesn't this kill the WC stones? (Black will sacrifice the BC stones.)
