Double Moves

We used to link to a page of Ron Drinning's Chess variants, but that page disappeared. The description of this game is based off of an archived copy of his site at https://web.archive.org/web/20041029004601/http://homepage.ntlworld.com:80/rondrinning/double.html. This game has been included here, because it has been referenced on another page.

Setup

Same as Chess.

Pieces

Same as Chess.

Rules

After each player moves one of his own pieces, he has to move a piece belonging to the opponent. This must be a legal move, of course, and the player who is moving may capture one of his own pieces with the move.
