224. Drive-By Rook. and 225. Drive-By Nightrider. Since I have an extremely full day traveling tomorrow, I'm putting a pair of related pieces up here. They're from a recent inspiration of mine, and I haven't had a chance to test them much yet other than to be sure that their listed XBetza does work in the XBetza Sandbox (and in the Play-Test Applet).

The Drive-By Rook is the basic form of this piece. It moves like a regular Rook, but also has the option of replacing a capture at the end with a capture in a space it's passing by. Basically, it begins its move, stops, does a rifle capture to the immediate left or right, and then continues. (RyascabyaqmR)

The four posts represent the guns it presumably uses to shoot to the side as it passes.

This same principle can obviously be applied to the Bishop and Queen, and it's not much of a stretch to also apply it to bent sliders such as the Rhinoceros and Griffin. Less obvious is an oblique piece: the Nightrider. (NNyascafyaqmNN)*.

As you can see, the front post is taken up by the horse's head; what you can't see here is that the back one remains, obscured by the Rider wings.

*I really do not know why the usual b in a rifle-capture goes forward, turning its longer path around, while f lets it behave like b should. If I had to guess, I'd say it had to do with how the relative chiral movements are arranged on a Knight. Regardless, there's a solution here, and it works.
