Go up one level in this thread


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.
