Fhayashi: My attempt.
JuhoP: at
. My final (?) attempt.
JuhoP: I earlier suggested this. I assumed that black can play Ba, Wb in sente, but then c is white's privilege, giving the same count as the new variation above. Anyway, this problem got me to look at 'The Endgame' again. In a similar situation the book suggested at
here, leading to the variation I give above. I suppose the reason is that it's in white's interest not to leave any aji or ko threats, but get the situation played out completely.
gets nowhere.

Pashley What about this?
Looks to me like both Black moves are forced.
However, I am not utterly certain Black cannot live in the corner with something like 4 at a. Doesn't look like it to me, but I'd like to hear stronger players' opinions.
JuhoP After Pashley's sequence, I think black can play this in sente, and then a is white's privilege. This seems to produce the same point count as Fhayashi's sequence, and 2 points less for white than my suggestion.
