[Diagram]
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]
Side diagram

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


[Diagram]
Main line

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


[Diagram]
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]
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]
Bad timing

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