I get 400k on a Celeron 466 with mostly material/PieceSquare. With decent eval I
expect to do around 250k.

BTW does everyone count nodes the same way? I for example don't doublecount D==0
nodes. Therefore, before *every* qsearch I do a Nodes-- to eliminate the
doublecount. My NPS would go way up if I did't do this decrement.
