Which is seriously wrong.

I'm going to take a break - can't be on the computer forever.

Matthew:out

Don't do "some more quick code". It is a waste of time. When returning from your break, I suggest that you start over from scratch, in your case from original Fruit 2.1. Now put in the code step by step, following all the advice that has been given here (I especially recommend what Lucas wrote), and test everything until it works, including "perft". Don't add 200 lines when you did not test the first three lines.

For your bitboards in the board data structure, I suggest that you use something like this:

uint64 bb_colour[2];
uint64 bb_piece[6];
uint64 bb_occ;
uint64 bb_empty;

instead of the array of 10 entries. I think it will be easier to debug.

As to your other mail that I only saw after sending my previous post, I don't think this improves your version of board_from_fen().
