I did not say that I have a method that is better than hashing but that I am not going to use hash tables in the way that they are used today by chess programs. I also think that 8 mbytes is a decent hash and the difference between 8 mbytes and 128 mbytes is small(I also cannot use 128 mbytes in my p800). I remember a claim by programmers that doubling the hash tables give 6-7 elo and I do not remember a claim that it is dependent on the time control. > >An opening book is a good idea for that reason.
