Chess for pacifists

I met up with Jason Masters today and he wondered what it would be like if you played chess with the goal of not capturing any of the opponent's pieces. He had a board handy so we gave it a shot. We added the condition that your pieces may never move backward; and, for the pieces that move laterally, they may never cross over the same square twice. You win when your opponent is forced to take one of your pieces or he is forced to put you in check mate. I won when Jason ran out of moves thanks to some unfortunately placed pawns. We then returned to normal rules where he proceeded to wipe me off the board. Lesson: looking at ordinary objects in extraordinary ways can be very entertaining.
