Beginner Exercise 43 Solution
  Difficulty: Beginner   Keywords: Problem

[Diagram]
Solution

White doesn't have to resist with W2, but nothing else works for her either. W2 at B3 fails because Black can capture at a. Now b and c are miai for the kill.


[Diagram]
The circled point is now a false eye

Notice how the BC's cause the circled point to become a false eye.


[Diagram]
Failure

Pushing at B1 allows W2 to live.



[Diagram]
How about this???

Sorry, I am new so if my suggestions look stupid. Sorry. Wouldn't placing on B1 do? White would place W2 forming an eye, but black can push in and stop from forming another eye, and B1 prevent white from forming a double eye on the other side.

How about this???

unkx80: I will not call your suggestion "stupid", questions are welcome. However, after W4 I do not see how BC can escape or be used to destroy the eye on the right side.

KarlKnechtel: If there is any misunderstanding here, I think the key phrase is "B1 prevent white from forming a double eye on the other side." Only one eye is needed on each side of the circled pair (and you already have the one on the left side), because the two sides are connected. You can connect through an eye (see elbow), and you only need two eyes for the whole thing. :) To be pedantic, black cannot prevent an eye with the throw-in at the squared point because those stones are not connected, and white can just CaptureThreeToMakeAnEye.

unkx80: Oh, I did not read that statement properly. But the "double eye" I presume is "two eyes"? But see the first diagram again, together with the statement "b and c are miai for the kill". =)
