2 ^ 64 = 18,446,744,073,709,551,616 How many positions is your program going to search? If you are Deep Blue maybe Billions, but for anything else probably less. In fact you can only store a few million positions unless you have lots of RAM. I am sure that with a search key of 64 bits that there are a lot of redundant positions, but your program is not going to find them in the course of a normal search. If you look at 30 million positions what is the probabity of any of those positions having the same exact search key? I don't know enough about statistics to give you the answer but I suspect that it is low. John John Coffey
