I have been looking at the suggestion but so far can not find a win for White here. What does White do after ? One important question that is open is whether White wins if everybody lives. DaveSigaty
Something like this ko ( - )? See below. DaveSigaty
at and wins on the right with a, ignoring any ko threat.
The ko threat at and a second at a are available in many of the variations and make it possible for Black to fight hard. The position on the rest of the board would help to evaluate this situation correctly.
Whenever White retakes the ko in the corner, Black will recapture at and ignore any ko threat.
dnerra: Whew, that is really a tough challenge to SL! Here are my two cents:
Maybe the idea of the "Finnish sequence" is to create a shortage of liberties as with in this diagram. Note that the white dragon virtually has five liberties (I think). At the moment I would expect a result similar to Dave's above, but I have to read further.
OK, just 48 more, and we have a $ :-)
Dave: How about this ?
dnerra: Isn't sufficient then? After , it's a just a liberty counting exercise :-) I think White is one liberty ahead, but maybe I am wrong.
Dieter: Well you are, no ?
go4joy: Isn't White still dead if White at , then Black to the right of . Doesn't Black still win the capturing race?
DaveSigaty: Unfortunately this variation has removed White's local ko threats (successive white plays at a and b will create only a temporary seki since the three white stones have no hope for eyes). Unless there is a 60+ point ko threat on the part of the board that is not shown, Black will ignore any threat and live in the upper left. As a result, looks impossible.
Lucky I had another idea: although is still ko, it is in White's favor.
Now there is little Black can do: is best, since any other move and White plays at herself and wins the capturing race. makes ko.
