This is known as an amazon
Its estimated worth is 12 pawns.
en.wikipedia.org/wiki/Amazon_(chess)I'll just jump over your Queen as well.
@GCH8215. It covers a 5*5 area already.
checkmates would be easier
15-20 because of the mates
200 if the piece is called Xena.
My guess would be something like 12 points initially, increasing significantly as the game progresses.
it would 9 plus 3 plus 3 which is 16.
