Go up one level in this thread

>- When BLACK is to move I use the bit-wise inverse of the hashkey

I'm not sure, therefor I ask to more experimented programmer to confirm what I
write, but I think it is not a good idea to use the bit-wise inverse for the
black size. It's like using a key that is 0xFFFFFFFFFFFFFFFF and this not
random, it's hand picked.

On the other hand I can not see what problem would it cause, but I often heard
that the zobrist keys must be made of "very randoms" numbers.
