And if you do add them, >do they come from sugguestions made by GMs? The rules rarely come from GM players. They often point out something I should be doing (or not doing). But if then takes lots of thought to encapsulate such ideas into the eval... efficiently... I often try inefficient implementations to see if the idea is sound, then if it turns out to be good, I try to make it more efficient later... As far as how many rules? That would be a wild guestimate. The evaluation code by itself is over 3,000 lines of C.
