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.
Dieter: - is too much of an assumption (see below)
The end result is seki.
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.
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 stones? (Black will sacrifice the stones.)
