I think that using the 50 move rule for this and several other large Chess variants is probably not appropriate. For example, my Chess engine computes the maximum number of moves to mate in this variant for Bishop+Knight vs King to be 69 moves, for Queen+King vs Rook+King to be 72 moves, and for Knight+Wizard vs King to be 85 moves! Perhaps for this and other large Chess variants it should be a 75 or 100 move rule, or possibly only if the game falls into one of these reduced-material mating patterns.
