More important for playing good go is:

0: what is sufficient for a group of stones to be stable.  Stable means that
you can tenuki and don't need to add a defensive move.  In the fuseki, a
single stone is often stable, even though it obviously doesn't have two
eyes :)
If your program adds stones to stable groups to make two eyes, it will lose
quickly.
