I've managed to solve the hash table problem - it wasn't really a problem, just
the way I was counting the nodes.

I've checked again and the cutfirst rate is actually 83% for the initial
position, which I am not happy with!  I can't understand why it is so low when I
do the standard move order of Hash, Good Captures, Killer1, Killer2, History,
the rest.  Any ideas?

I see you're entering the Dutch.  Is this you x88 or your bitboard program?  Are
you still using C++ Builder?

Regards,
