Beginner Exercise 16 Solution
   

[Diagram]
Diag.: Solution.

The key is at 1, making a tiger shape. Notice that black cannot play at a.


[Diagram]
Diag.: Solution.

If black 2 blocks, white 3 sagaris and secures one eye. If black 2 at 3, then white 2, black a, white b, black c, white d, and white still secures the eye on the right side.


[Diagram]
Diag.: Solution.

The interesting part comes when black 4 attempts to destroy the other eye. However, white can play as in Beginner Exercise 19, making the throw-in at 9 and capturing three black stones in a connect-and-die to form the second eye. Subsequently, if black a, white b ataris.



[Diagram]
Diag.: Failure 1.

White 1 (or a) trying to expand the eye space fails instead. The wedge at 2 is the vital point, and is a common killing technique. Now it is not possible to make a real eye on the left side.


[Diagram]
Diag.: Failure 2.

Six die but eight live, so connecting at white 1 does not work either.
