You need to convert square numbers that are in the range 0..255 into those in the range 0..63 (using SQUARE_TO_64) before indexing any of the magic_bb_xxx arrays. Maybe you can do this within bishop_attacks(), rook_attacks() etc.

Is there any advantage to a 16x16 board when using bitboards?

I don't understand your question, do you mean "is there any advantage of a 16x16 board"? If not, can you please explain your question?

Well, maybe we should not start a discussion on what is correct English idiom.


Why would there be ANY square re-numbering when using bitboards... For bitboards, squares 0-63 is the ONLY thing that makes any sense at all. Leaving a 3-bit rank and 3-bit file which is perfect.

Makes no sense to consider a bitboard which must use 0-63, and then re-map to 0x88 or anything else...
