Corner pattern

The formation on the left commonly occurs after White plays a wedge on the top. White's stones form a solid base but Black has a tesuji to capture one of White's stones.

[Diagram]

Tesuji

B1 is the tesuji. White should give up the stone and take sente with the sequence to B7.

[Diagram]

White resists

W2 offers strong resistance. If white keeps resisting with W8, Black will cut at B9.

[Diagram]

B19 at B11 and W20 at B15.

B11 start a two-stone edge squeeze.

[Diagram]

Black captures everything

After B21 Black captures everything. White is clearly worse off than if she had just given up the stone.
