VIncent...  I had outside passed pawn code before anybody I know of.  I
had pawn majority code before anybody I know of except perhaps one or two
commercial programs and I had this code before most commercial programs did.

You can call something "basic or rude or 'primitif'" all you want.  The ideas
are well-grouned in sound chess and they work very well.  IE for years your
program has played like an absolute patzer in endings.  If my ideas are
"primitive" then what are yours???
