I am currently implementing the same attacks after readinf Ed's article. either i got it wrong or Ed's error in his diagram. instictively, i reversed the bits(BIT0 and BIT7) as left is usually the higher order bits and seems better. so 1 white pawn + 1 white bs attacking a sq is x = 01011000 (lsb is right) so 1100 (masking off left 3 bits) is very powerful. if black has king + queen attacking same sq == y = 01000011 so, x & 31 > y & 31 ( masking off the highest 3 bits). I think Ed mentioned we figure out how to use the 3D tables. Rasjid
