I suggest a couple additional rules to traditional chess. The Silence (bishops) can move without being seen every other turn. Also, the Amelia Pond figure cannot move for the first twelve turns.
What other rule changes do you suggest to make playing with Emmi Visser's excellent chess set optimized for Whovians?

The Weeping Angel Knights can only move if no other pieces are facing towards them.
