DEMONSTRATION (II)conclusion: In the multi-path model, Marshall
(Knight+Rook)is of itself kin to combining apples and oranges, elements
from the extremes of the categories. (Knight+Camel) is properly a compound of leapers. Knight plus Zebra is a compound. Rook+Sissa is a compound, in
part, making three-path to Rook squares. Cardinal(Knight+Bishop) is a
'pseudo-compound', having combination rules of movement for patenting
and also everday purposes. Neither do we consider Bishop+Antelope(4,5 leaper) a compound, but a combination piece. Antelope does not augment the Bishop's move with a pathway, as for instance Crooked Rook would. Disparagingly, 'pseudo-compound' fits also because of improbability that movements combining powers at opposite extremes, namely leaper and one-path slider, could be very effective within one piece. Hence their unpopularity. The term is in nature of argumentative style because more important is accurate description of the rules of movement. So, in our system, there are compound leapers and compound sliders(like QUEEN!) and compound multi-path movers(FALCON, SCORPION, DRAGON, PHOENIX, ROC) and others(like riders), but no compound of Leaper and Slider. Marshall or Cardinal as compounds are misnomers and rather combination pieces.
