Is this "static null move pruning" actually doing a null move? It sounds more
like a futility-type scheme from your description.

Btw, I've spotted a mistake on your web page for Gothmog. It says "on fast
computers it is probably good enough to offer the average chess player a good
match". Surely it should say "average master..."?!

(You do seem very modest about your program!)
