Once again, you guys have provided a ton of useful info. Thanks so much!

First of all, I have to apologize - I forgot to mention that I do use a history
heuristic table. Just a very simple one...if a move fails high, I increment
history(square.source, square.dest). Then I add the MVV/LA score if it's a
capturing move, and sort by the sum of those two. I had hash tables, aspiration
windows, and null-move, but I took them out to seek if I could get my move order
% up without them.

As far as  killer moves, what usually defines them? I haven't read much about
them.

And with reference to Andreas' comment, do most of you agree? It makes sense to
me that if both move order % and nps are low, it could be something in
quiescence. What do you guys suggest I look at first?

Thanks a ton for your help! Andrew
