I am not so sure if the programs of 1997 will win the match. 2)I also believe that not having bugs is important and the deep blue team simply not had the time to test. 3)I also do not know the speed of deeper blue. It is possible that they did only 20M nodes per second and we have no proof except what IBM said. I do not see a reason to believe IBM after Deeper blue stopped to compete. It is natural if people suspect that you have something to hide if you stop to play. Uri
