Under the stones

In the space created by the four captured stones, White can recapture two stones.


Pitfalls

[Diagram]

Pitfall 1

Obviously, White mustn't answer 2 at 3 here.

[Diagram]

Pitfall 2

If White hastily answers the atari by (temporarily) saving her stones with 2, Black 3 kills.

[Diagram]

No Under the stones

If White fails to make the four-stone sacrifice, and connects at 5 here, then Black 6 takes three stones, and there is not enough room to play "underneath".


[Diagram]

Failure

White 1 makes one eye in the corner. Black 2 makes miai of a and b to take away the other eye.

[Diagram]

Inferior for Black

Black 2 here would allow White to live in ko.
