I am only 12 kyu on KGS so this is definitely a kyu-level attempt.
Throw in with to create a bulky five shape.
My first instinct was to throw in at to create the bulky five shape but
refutes that.
This seems to be another solution.
White dies.
Dieter: (I have to write something on page 5000?) This variation is to be considered too, I think. After , a play at 1 and at the marked stone are miai to live.
unkx80: Thanks for the attempts. =)
Black should play at . Then if
connects,
kills the group. If
is played at
instead, then Black plays at
and White is still dead (a is a false eye).
If White captures immediately, Black captures the two stones on the left.
If here, there is no eye at the
stones and a dead shape in the eyespace.
Goantti: I'll add a missing variation.
White can try but then Black plays
.
Now the points a and b are miai to kill.
I calculated also the variation where instead above, White plays counter-atari at
. It would have worked if there had been one more line of white stones on the right. In this case White would not take at a but would atari at
instead.
Now kills the three
stones (under the stones). If
then
oshitsubushi prevents a dead shape.
