This is very interesting Gerd. Which approach do you think will work the fastest on 64-bit cpus? Rotated, MMX non-rotated, or plain old non-rotated? A lot of people say rotated are fastest, now there is this MMX that is at least on par with rotated bitboards, and I remember reading a while back that some people were using non-rotated bitboards and doing classic style board scanning to find attacks and such, and that this old-non-rotated method worked fastest for them (maybe because of better cache hits?). So which do you think will be the winner on 64-bit machines? We have all of this talk about which is the fastest on 32-bit machines, but before too long 64-bit will be here and all of the conclusions we've drawn might be turned upside down. What if plain old non-rotated bitboards is the winner on 64-bit hardware? Any thoughts? Russell
