makes miai of a and b to live.
After , there are real eyes at the circled points.
After , there are real eyes at the circled points.
Charles I have had an off-line query about this.
What if we get the plays up to here?
Then sets up an oiotoshi. Now if White takes
, Black gets eyes by playing atari at the 1-1 point.
The other 1-2 point is not the solution. White pushes through with and plays at the vital point
, making miai of a and b for the kill.
The 2-2 point doesn't provide life either.
White pushes at and creates a situation very similar to problem 1. As in that problem,
is the vital point, and White strikes it to kill Black.
Playing at a is probably even a better way for White to kill.
unkx80: I believe that is OK, but playing
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 suffices, but it doesn't.
White says "There is death in the hane" and plays . After the eyespace is further reduced with
, Black is left with a bulky five and White strikes at the vital point.
unkx80: After the hane at , Black effectively has an L-group.
Playing at here doesn't help Black.
This is just one variation. Note: Playing at
would make Black play at
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.
