Wouldn't black rather live by playing at b or c instead of inside his own territory?

unkx80: Good point here, but the emphasis here is that white has to do something inside black's territory before he can even think of killing.

Failure.  

joshsz: My first thought was to close off potential eyespace, but after looking at it some more I see that black can play at and create two eyes.

Jacob4Jesus: should be at a. As is, a and b make a false eye and at b kills.
