Kanazawa Variations 46
Keywords: Problem
Authors: DieterVerhofstadt, unkx80 This is a failure diagram from KanazawaProblem46
I would like to ask, why doesn't Black simply play at 2 instead? Seems dead to me, but now it is 1 am Singapore time, and I might be wrong... --unkx80 I don't know why I missed this one. At the time I started this page, I was or should have been clearly awake #:-7 --Dieter
Now, how about the strongest responses for both ?
This results in an approach ko. If Black 10 fills a liberty at a, then White 10 makes seki. What happens if Black plays 4 at 5 in this diagram ?
This is another approach ko, but now Black takes first, and his loss is smaller if he loses the ko, so this is probably better. (please correct, unkx80, my previous contribution was terrible).
If White 6 here, then Black can cause an AlmostFill with a FarmersHat at the marked points and White is dead.
However, White plays kosumitsuke at 2 and Black has to play 3 to prevent two eyes. Now White throws in at 4 ...
... and she has enough outside liberties to fill in the inside liberty, putting Black in damezumari. This is a copy of the living page "Kanazawa Variations 46" at Sensei's Library. ![]() |
