I tested the numbers you use in Crafty, and the minimum hamming distance between
any pair of numbers you generate, is 14. That's even worse that 16. Just for
your information, only one pair of the numbers you generate, have this low
distance. It is the 185th number and the 394th number you generate. That is, the
keys for w_bishop_random[15] and b_queen_random[32] have a hamming distance of
14.

Am I missing something here or are you? :)
