TFG9 - What the Finnish Dan Players Suggested
I have been looking at the suggestion but so far can not find a win for W here. What does W do after B 4? One important question that is open is whether W wins if everybody lives. DaveSigaty
Something like this ko (6 - 10)? See below. DaveSigaty
W 7 at 3
W 9 at 5 The ko threat at 10 and a second at 'a' are available in a lot of the variations and make it possible for B to fight hard. The position on the rest of the board would help to evaluate this situation correctly.
W 5 at the marked W stone
dnerra: Whew, that is really a tough challenge to the SL! Here are my 2c: Maybe the idea of the "finnish sequence" is to create a damezumari as with W1 in this diagram. Note that the white dragon virtually has 5 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 $ :-)
AvatarDJFlux Since when a dollar is made of 50c??!? Dave: How about this B 2? dnerra: Isn't W3 sufficient then? After W5, it's a just a liberty counting exercise :-) I think W is one liberty ahead, but maybe I am wrong. Dieter: Well you are, no ? dnerra: Ooops yes, I didn't see B5. So W has to play at 4 instead of W2, in case mutual life is sufficient?
go4joy: Isn't white still dead if W at 4, then black to the right of 4. Doesn't black still win the semeai?
go4joy: referring to Dave's third diagram
go4joy: This is the best I can come up with. White will need a big ko threat. At least this variation removes black local ko threats. DaveSigaty: Unfortunately this variation has removed W's local ko threats (successive W plays at 'a' and 'b' will create only a temporary seki since the 3 W stones have no hope for eyes). Unless there is a 60+ point ko threat on the part of the board that is not shown, B will ignore any threat and live in the upper left. As a result, W 3 looks impossible.
