Vincent: After , black must prevent the connection with .

and are forced and makes life.

Harleqin: What happens if White plays directly at ?

Vincent: Good point. Black must play a.(Since this gives black one less capture, it is actually better than my first suggestion.)

unkx80: What about this?

HermanHiddema: This is the refutation of the attempts posted earlier.

Vincent: Hmph! You're right. (And I thought I was so clever).

 

HermanHiddema: The tesuji seems to be to play 2-2, here's one possible diagram (11 at a), but there are many complicated variations and I haven't checked them all. The basic trick is to make an eye in the corner somehow (or capture some stones if black wants to prevent it).
