The amazon's value is estimated to be 12 or 13 points in the
chess piece relative value system. It is extremely mobile, can control every square surrounding itself in a 5×5 area, and can force checkmate by itself. In contrast, although the gryphon (or
griffin) from
Grande Acedrex (which moves one step diagonally before continuing outwards as a rook) would seem to have the value of two rooks (10–11 points), the squares it attacks are more dispersed, and it is more easily defended against than the amazon. In the
endgame of king and amazon versus king and
empress (rook+knight compound), the amazon usually wins; however, in a few positions, the weaker side may force a
draw by setting up a
fortress. Such a fortress forces the side with the amazon to give
perpetual check; otherwise, the side with the empress can force a simplification or give their own perpetual check. King and amazon versus king is a forced win for the side with the amazon;
checkmate can be forced within four moves. In comparison, the queen requires 10 moves and the rook requires 16. In fact, the amazon does not even require its king's help to force checkmate (as an example of a checkmate position, the king is in the corner and the attacking amazon is a knight's move away from it), and this great power is the reason why it is not seen as often in chess variants as the princess or empress. ==Symbol==
