It could also be that the 'patches' for the eval function would be to taxing on
a PC system. How expensive would certain things like the x-ray effect of pieces
be? You know, lining up a rook-rook-queen battery behind pieces and pawns for
devastating effect, or pawn-bishop-queen. I once proposed this to a programmer,
suggesting values for who controlled a square through this battery effect (even
though the piece at the end would be quite a distance from the controlled
square). The idea was to speed up certain tactics this way, and the positional
understanding of the program on who had better square/space control. When I was
told this was too costly, I realized that systems that had super hardware
offered possibilities one could only dream of with PCs. I have no doubt that DB
probably had MANY such dreams implemented.
