Kanazawa Problem 31 / Solution
Sub-page of KanazawaProblem31
White 1 makes an eye at a and makes miai of b and c for the second eye. It is clearly the vital point.
White 1, 3, 5, 7 and 9 all serve the same purpose: enlarging the eyespace, which is generally a good idea. Black occupies the vital point at 2 and prevents White from making 2 eyes. I seems as if we are heading for a seki (see next diagram) ...
If White plays 1, then after all the circled liberties are filled, Black can give atari at a, White protects at b, and her eyespace is almost filled with a farmer's hat. If White plays at a herself instead of 1, eventually her eye space will be almost filled with a bent three. So, White is dead either way.
White 1 makes an eye where there is already one. It is not vital. Black can now kill by playing either of 2, 3 or 4. Any of those three moves makes miai of the other two to kill White. Choice 2 is shown. After 8, a and c are miai to keep White at 1 eye. Remark: once again, without the cutting point at c, there would be the possibility of seki.
