Then a Mammoth with 5.4198 compared to a Rook with 5.8148 seems to be about 1/2 Pawn unit weaker. Additionally I want to mention, that when exchanging pieces not only their average piece value will vanish from the board, but also their positional influence. Thus it is quite often when exchanging Knights with Bishops, that a Knight will have the bigger positional influence at the board thus making an exchange nearly equal. But this does not hold for the whole game. Regards, Reinhard Scharnagl. P.S.: In my calculations I prosumed, that a mammoth has to slide to its two distant targets, thus not jumping over pieces like a Knight.
