4-5 point 3-3 invasion

3-3 approach  

White comes in at the 3-3 point in search of a quick way to live.

Black normally answers with a diagonal at a, giving White a choice of direction, or a keima at b to build a wall on the upper side. The attachment of c has many variations. If Black has a stone the left side, he may play the otherwise inferior kick at d.
