Side patterns

Shoulder hit

[Diagram]
Shoulder hit  

W1, diagonally approaching a stone on the third line, is know as a shoulder hit. Black has several options for dealing with this move, the most important of which are a and b. Playing elsewhere is generally a bad idea in this situation.


Capping play

[Diagram]
Example  

W1, approaching a stone on the third line from above, is know as a capping play. Common responses include a and b. Ignoring this move is less serious for black than ignoring a shoulder hit.


Approach

[Diagram]
Approach  

The approach W1 is common when dealing with a stone on the fourth line.
