Standard chess assumes all soldiers follow their king's orders. But what if there were traitors in the ranks? What if some soldiers were taking orders from the other king? Traitor Chess makes this happen. Now you have the chance to move your opponent's pieces! But of course, traitors must be careful not to be caught and executed. The circumstances governing when, how and why such 'traitor moves' can occur are contained in this book. It also includes rules regarding special circumstances and answers to common questions, e.g. "Can my opponent move my piece when I'm in check?" Limitations and optional variations are detailed together with information regarding how these may be annotated. Other than an ordinary chess set, basic Traitor Chess requires no additional materials. A small number of additional materials may be useful for some of the optional variations however all of these may be borrowed from other common board games (e.g. backgammon).
