One of the nice things you get almost for free with attack tables is that it is almost trivial to compute safe mobility rather than pseudo-legal mobility. >Calculating attack tables is very slow, but you can use them for a lot other >things. How slow is the attack table calculation for you? Do you have a couple of test positions we could compare? In the opening position (which is probably not a good position, because all sliding pieces are blocked) I generate my 16-bit attack tables almost exactly 1000,000 times per second on a PIV 2.4 GHz.
