Main line

Black 1 makes miai of a and b to live.


[Diagram]
2 and 3 are miai

After 3, there are real eyes at the circled points.


[Diagram]
Yes they are

After 3, there are real eyes at the circled points.



[Diagram]
Wrong (i)

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.


[Diagram]
Wrong (ii)

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.


[Diagram]
Wrong (iii)

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 an L-group.


[Diagram]
Wrong (iii)

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.
