Tord said something about having the null move search a window
wider than -beta+1,beta and and then testing the return value
against alpha-MARGIN. If less than that, a faillow and then
extending.

Has anyone else with PVS search implemented mate. Can you just
include your code fragment in reply to this. I have programmer's

Thanks. Stuart
