Xuanxuan Qijing Problem 10 / Attempts

Karl Knechtel: Did I miss the alleged strongest resistance?

6 at a is no good; the stones are trapped due to damezumari  

Variation  

Variation con't - ishi no shita  

If White tries to bridge under  

... con't. (exchanging a for b only delays the inevitable?) Here 8 and 9 are miai  

unkx80: As far as I can see, this problem is essentially the same as Under the Stones Problem 4. Over there, Hans pointed out that the solution should be a ko.

So I did miss it then... :(

W throws in for ko (last chance)
