Then why did it take you so long to add code for distant passed pawns?  Pawn
majorities?  I've had it "forever".  Isn't your program the one that thinks
a queen vs two rooks is something like +4.0 for the queen?

And exactly how many _day_ did it take you to come up with that beauty???

Can you stop with the "rectal math"???  (rectal math means pulling numbers
