There are programs that do not use bitboard. I think that wasting too much time about changing the data structure of the chess programs is a mistake. There are discussions about the question if bitboards really help. Even if they help and can do the program 10-20% times faster then it still seems to me a bad idea to waste time about it when there are a lot of ways to improve chess programs without it. Uri
