Beginner Exercise 54 Solution
   

The original discussion has been moved to Beginner Exercise 54 Discussion.

[Diagram]
Diag.: Solution.

If black plays first, he can make two eyes immediately at 1, so white has to play at 1 to stop black from living.


[Diagram]
Diag.: Side Diagram.

Black 2 can solidify an eye at the bottom. However, white 3 is double atari and will destroy the eye at the top, leaving black dead.


[Diagram]
Diag.: Main Line.

Black has to play at 2 or a to prevent the double atari. But white 3 kills.


[Diagram]
Diag.: False Eye.

Even when black plays the two marked stones to capture the two white stones, white still can make a throw-in at 1 to turn it into a false eye.


[Diagram]
Diag.: Trapped.

White has to be careful not to play at 3, thinking she can capture the marked stone. Black 4 traps the two white stones including 3 in a snapback, and lives.


[Diagram]
Diag.: Bad Timing.

White 1 is the correct way to falsify the eye at the bottom, but is too early. Black 2 lives.
