The Wide Receiver is supposed to (in addition to the forward Rook and backward Bishop) start with a single Wazir move sideways, then turn 45 degrees toward the front to move one more space as a Ferz, and then turn 45 degrees again to slide directly forward like a Rook. There shouldn't be any Knight moves in that one.
So, interpreting this, I'd go with sf[W?F?qR]?
(At the least, if it's as simple as that, I'll be happy.)
