Superqueen
Fairy chess piece
Fairy chess piece that combines the power of the queen and the knight, i.e. it can move not just like the queen, but can also make a knight-move:
= +Note that it can control 5x5 squares around itself.
Its value is far more than the queen's. It is somewhere around a queen plus a knight, maybe a little bit even more. Using the usual valuation of the pieces, its value is approx. 12-13 points (the queen's is 9).
The superqueen can mate the king in its own. The special is that it can do it without the support of its own king.
