Hello,
i want to include pawn hash tables in my chess program holmes, but i don't know
how i have to calculate the hash index and the hash key.
I think the hash index of the position will only calculated with the pawns on
the board like the following,
for (pos=A1;pos<=h8;pos=pos+1) {
if (figure[pos]=pawn) {
PawnHashIndex = PawnHashIndex ^ RandomIndex[pos].index;
}
}
is this right??
How can i get a good hash key? What have i calculate with xor?
Thanks for each information.
Andreas
