I know that part of the program can find the draw if you let them to play against themselves. You need only to let programs to play against theirselves them and learn from the games in order to find the draw. programs do not use even 10% of their time for doing it and I believe that it is a mistake at long time control and that it is going to be a mistake at tournament time control because the hardwrae is getting better. I also do not agree that the move Qc1 is a quiet move. It is not a check but it is easy to see that this move threat to take the bishop. A real quiet move do not have a threat to take material in the next ply. > >Hang on to the position for a while.

The reason is that I believe that kasparov is not going to repeat the mistake of playing against something unknown. I believe that Deeper blue could win kasparov in a match because of the fact that kasparov could not see games of the same machine and could not buy something similiar to the same machine to learn about the weaknesses of deeper blue.
