Subject: Node counting in Crafty 14.2 and 15.20

mr Hyatt,

I was comparing the speed in nps of my own program against that of Crafty. I
have the sources for 14.2 and 15.20. I noticed that in Search there is a
difference in node counting between 14.2 and 15.20. In 14.2 you do not count
illegal moves, in 15.20 you do. Is there a reson for this?

15.20
    } else tree->nodes_searched++;
    UnMakeMove(tree,ply,tree->current_move[ply],wtm);

Is this maybe the way nodecounting is done in other programs as well, for better
comparising?
