Q. What happens if my Rook is adjacent to one of my own pieces, I play BOMBARD to jump over that piece, and my opponent plays BOG?

A. Count the square beyond the adjacent piece as the first square of the move (i.e., the Rook stops its move on the other side of the adjacent piece). Similarly for GHOSTWALK — the first empty square counts as the first square of the move.

Q. Using GUARDIAN can a pawn land on another piece and capture it?

A. It may not land on a piece.
