A maybe funny question:
What happens to a pawn when it is converted into an undead piece? Say, a white undead bishop attacks a black pawn: Does the black pawn turn into an undead white pawn or does it turn into an undead black pawn under white's control? The difference between the two is the inherited directionality: By becoming an undead white pawn the black pawn turns 180 degrees and marches against his old camp; while an undead black pawn under white's control continues to march against the white camp (and may block white pawns in their progress).
Another question:
Can an undead piece attack a life piece of its own camp? Because this action may strengthen the piece by taking its life it might be a favourable move.
