Kanazawa Solution Six
Black 1 makes miai of A and B to live.
After 3, there are real eyes at the circled points.
After 3, there are real eyes at the circled points.
The other 1-2 point is not the solution. White pushes through with 2 and plays at the vital point 4, making miai of A and B for the kill.
The 2-2 point doesn't provide life either. White pushes at 2 and creates a situation very similar to problem 1. As in problem 1, 4 is the vital point, and White strikes it to kill Black. Playing 2 at A is probably even a better way for white to kill. unkx80: I believe that 2 is OK, but playing 4 at 'a' is a far better way to kill. It avoids the "bent four in the corner" by the sequence black 'a', white 'b', black 'c', white 'd' altogether.
One would think that enlarge the eye space with 1 suffices, but it doesn't. White says There is death in the hane and plays 2. After reducing the eyespace further with 4, Black is left with a bulky five and White strikes at the vital point. unkx80: After the hane at 2, black effectively becomes a L-Group. See The L Group Is Dead.
Playing at 3 here doesn't help Black. This is just one variation. Note: Playing 6 at 8 would make Black play at 6 and White at A. This is a bent four in the corner shape and it's dead too, but if you can avoid that shape and kill in a simpler way, it is better to do so.
