There are actually four kinds of half-crooked Queen. The even-length moves of the crooked Bishop are the same as the standard Rook (except with different pass-throughs), and the odd-length ones are at ever decreasing angles to the Rook; likewise the crooked Rook and the standard Bishop. Therefore Rook+Crooked Rook and Bishop+crooked Bishop are valid compounds, the latter being a colourbound but otherwise Queenlike piece. There is also a crooked Nightrider, the Quintessence of Quintessential Chess. This leads to a whole familiy of crooked and half-crooked versions of Marshrider (Rook+Nightrider), Cardirider (Bishop+Nightrider), and Acerider (Queen+Nightrider)!
