The Half-Duck Knight sits inside two diamonds, one described by the ferz-dabbaba (1,1) + (0,2) and the other described by what Charles Gilman describes as the endknight (0,3) + (1,2).
In a 7 x 7 box, the spaces to which it does not go are the wazir, alfil, camel, zebra and (3,3) spaces (represented by Larry Wheeler as a Rhino).
