Royal Amazon Chess

Royal Amazon Chess is the result of wondering how much is a piece weakened by being royal. So the Queen was made royal and promoted to an Amazon (Queen + Knight).


Setup is the same as for Orthochess, except that Queens are replaced by Royal Amazons.
Royal Amazon Chess Setup.


The rules of Royal Amazon Chess are identical to those for Orthochess except that the Queens are replaced by Royal Amazons. Royal Amazons move like Queens or Knights. They are subject to check and mate as are Kings, and thus can not enter or remain in an attacked square. They may, however, pass through an attacked square. A Royal Amazon will offer check to another royal piece, even if that royal piece is defended.

The King is still royal as well, so each side has two royal pieces.

A Pawn may promote to the usual Knight, Bishop, Rook or Queen, but not to a Royal Amazon.

The Royal Amazon army vs the standard Orthochess array makes for an interesting match, and allows comparison of the strength of the Royal Amazon as compares to the usual Queen.


It is surprising how much weaker the Royal Amazon feels than a Queen, even allowing it to move through attacked squares. As can be seen from the above sample game, using it to attack is almost certain to be a lethal mistake. I rather doubt that the variant with Royal Amazon vs Queen is balanced -- I think the side with the Queen will have a distinct advantage.
