Standard replies to 3 space extension invasion
bobulatorm: a, b and c are all standard responses, depending on surrounding board positions. b is a strong attack when B has supporting forces nearby. c is a slightly weaker attack, and a is only to be played as a purely defensive attatchment.

White can now cut back at a or draw out at b.
Black sacrifices to get outside influence, while White gets some territory.
HolIgor: Acceptable. Usually
Diagonal attack
diagonal attack attempts:
still black needs to defend at a

Weaker attack
