I invented a variant with two new pieces: the Heir and the Maiden

The Heir "H,h" (or prince) moves as a king first and then as a knight or only as a night if the king move is blocked, the Maiden "M,m" (or princess) moves first as rook and then as bishop and viceversa.

The Heir cannot put himself in check if the King is in check and converts to king  if the king is checkmated.

The problem is (almost always) dealing with the configuration files of some of the few avaible copnfigurable fairy chess engines: Fairy Max, Sjaak II, Nibiru, etc, that not even H.G.W. Muller seems to understand. I dropped the towel with fairy max, it bit to bit flags makes it powerful but unfriendly to humans, it would be awsome if it had some gui to configure the pieces, by the other hand Sjaak II seems less complicated but more limited as I leart experimenting today.

The Sjaak's manual says: that to define a leaper that can be blocked you should use the following sintax:

Move: leap (1,0)+(1,1) & (1,2)

This should define a knight that cannot move towards a piece on the next square but on the practice of my tests is just a knight.

So if I understood correctly sjaak's sintax my Heir should be:

Move: leap ((1,0)|(1,1))+((1,2)) #the king + knight  move

# Move as a wasir (1,0) or (|) as a fertz (1,1) (like a king) and then  (+) moves as a knight (1.2)

Move: leap (1,2) # the night move

But the resulting move is just (3,2)|(3,3), leaps 3,2 or leaps 3,3 and cannot be blocked.

The maiden side should be esier as it's move should be:

Move: slide ((H,V)+(A,D))|((A,D)+(H,V))

BUT APPARENTLY SJAAK CANNOT ALTERNATE SLIDES, I know fairymax can do it but I'm not into bit to bit analysis.

white bishops mark whe the Heir can move black pawns where can capture.

Anybody can give me a hint on how to edit sjaakII or fairymax to make my variant?
