Generates a move from this board position.
If the game is already over (somebody has won), returns RESIGN.
Derived Benzene players that use different search algorithms should not extend this method, but the protected virtual method Search() below.
If state is terminal (game over, vc/fill-in win/loss), returns "appropriate" move. Otherwise, calls Search().
- Bug:
- Subtract time spent to here from max_time after each step.
