Boshi
   

Boshi means capping play and is visualized in the following diagram. It can be seen as the counterpart of the ikken tobi.

[Diagram]
Diag.: Boshi

[Diagram]
Diag.: Boshi as a reduction move

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


[Diagram]
Diag.: Boshi as an attacking move

Here the boshi 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.
