    Plays the following, in priority order:
    1. If own group has single liberty, play there
    2. Amongst opponent groups without two eyes, find the one with the least
       libs, and fill the one with the most second order liberties. If there
       is a tie pick one at random.
    3. Make a random move that doesn't fill own eye
    4. Pass
