1a. A piece does not have to be developped to be considered dangerous on the
    Queen's side or King's side of the board, the point in case here, is
    weather to Castle so soon on one side or the other without realizing the
    future potential of those pieces located on the same side of the castled
    King.

2a. Therefore, a subroutine would be very helpful on the earlier stage of the
    openings, where the center is closed. When a computer program play against
    a GM, it should not play the same opening so blindly as a human. what is a
    good opening for a human is not always a good opening for a computer.
