'No player may use a machine for active assistance in analysis.'
Does this mean we cannot use Zillions at all, or simply that we may not
have Zillions search the better move, but are allowed to enter all moves
manually for both sides, and if so, only the moves effectively played to
see the current situation, or also the moves we intend to play or believe
our opponent will play, as we would with a physical chessboard in
correspondence play (but then, Zillions could tell us that a move we
wrongly foresee would be illegal, unless we write a zrf which would allow
each piece to go anywhere on the board and has no winning condition)?
