Side

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.


Invasion

[Diagram]

Invasion

There are standard sequences on the side when invading a position, see Three Space Extension Invasions

[101] Bill: It seems strange to call these enclosures, except perhaps the Iron pillar, the 3-3 and the kosumi. In general it takes two additional plays besides the 4-4 to secure the corner. That is an important idea.

[102] Bill: Conversely, it seems strange to call these enclosures, because the 3-3 itself suffices to secure the corner. That is another important idea.
