Hi, I'm from Italy and I am still writing my chess engine in c language. I downloaded the source code you told me, but I would like to know something more. I know for pieces like rook,queen and bishop we should look at the rank(or file)_attack[64][256] array,the first index refers to the square the piece sits on and the second refers to the state of the rank, so I want to know how to initalize this array of [64][256]. I know what state of rank means, It can be represented by a number like 00101001, I know about the rotated bitboard, so I will be pleased if I could receive some explanation about that. Thanks a lot.
