Hi David,

>What are the, say, 10 best ideas/techniques to cut this number down?

The other posters in this thread have already pointed out most
of the known things to do in your case.

If you are looking for more detailed explanations and some pseudo-code
of futility pruning in the quiescence search and elsewhere, you might
want to take a look at my book "Scalable Search in Computer Chess".

Please take a look at http://supertech.lcs.mit.edu/~heinz/node1.html
for more information about the book.

Cheers,
