4-4 point low approach, high extension, hoshi  



[Diagram]
invasion  

white+circle is three spaces away, so B1 is a likely invasion later in the game. Aside from local responses, normally a, immediately seeking compensation in the corner is possible.

Secure corner, threaten invasion  

Another followup is B1, which secures Black's corner and threatens to invade at a. W2 is frequent when White wants to respond, or she can first play a forcing move attaching to B1.

[Diagram]
weakness/supporting extension  

Black should play or have an extension around or beyond the midpoint of the side. Any closer and the 3-3 invasion will render this formation inefficiently cramped. If there is no extension, White is bound to attack at b.

[Diagram]
Central development  

Another idea and direction is B1, which also threatens to invade while developing towards the center and the left side. a is older, slower, and similar. White can defend at W2 or again play in the corner, b. Attaching at c can often be reasonable for making a living shape.
