Zobrist hashing was originally invented for computer chess and is the most popular hash method there. For chess you need 13 different values (for 6 piece types for each side, or an empty square) at each square. In addition it is best to hash in the castling and en-passent status as well. All this makes it a bit more complicated than for go, but still quite manageable. There are the same benefits, in that it is very efficient to incrementally update the hash value after making a move: only the squares affected need their contributuitions recalculated rather than the whole board. 198.142.44.32 00:37, 23 March 2007 (UTC)
