Examples

[Diagram]
Cap as a reduction move  

Here the cap reduces the moyo formed by the black stones. If Black were allowed to play at 1, his moyo would be perfected.

[Diagram]
Cap as an attacking move  

Here the cap blocks off White's natural escape to the center. The purpose can be twofold: make territory at the top while White is fleeing along dame points and/or create thickness towards the center.
