Some information about the search:
search depth is 5 to 6 ply. (fixed)
For the last 14 open places the program does a full search to see if it can do a move with wich it wins. If it does you have lost, and there's nothing you can do about that!
The last 12 open places the program calculates the optimal move.It displays by how much it wins or loses. This can only get worse for you (when making non-optimal moves)
