+p.
+ All rules are as in normal chess, except for the following: each turn,
+ a player has the right to refuse at most one move of the opponent.
+ To refuse a move, re-play it from end to starting square.
+ To avoid unnecessary complications, castle is not allowed.
+
+p.
+ Two moves promoting the same pawn on the same square, but to a
+ different type of piece, count as two different moves.
+
+p.
+ If a player has only one legal move, refusing it will end the game,
+ either by checkmate or stalemate (draw).
