I've heard quite a bit about bitboards in posts here and I'm trying to figure out what they are and why they increase performance so much? Are there any links to go and read an article about them? I think they are a way to represent the board but why rotate them and where is the big benefit? Right now I basically use a variation on the basic array of 64 integers to represent the board (ala TSCP) and I get about 30K nodes/sec on a Pentium 200. But I see discussions of 100-200+ K nodes/sec on similar hardware with bitboards! Thanks in advance for any hints/tips... Greg
