The only negative thing i can say is if Deep Blue/Thought have more Knowledge
than is in Commercial Programs why were the correct moves played then?
Also if Fritz 7 really picked these will it change it's mind later and when will
the Fritz search in Ply depth be equal to DB/DT if it isn't already?
Not that this game is an end all say all , it is only one example and i am not
100% convinced Fritz or any other program is better but from now on i will only
look at 1996/1997 match games as the one above is NOT officially Deep Blue and
that incarnation did not have some of the features that Deep Blue Definately
had.
