Die Schwalbe, Nr. 13397

1. Dxh8# Under AP, Black claims that he moves and to prove that he starts and should castle sooner or later. 0. ... 0-0? 1. Dg7#! White accepts that Black starts, but mates him anyway! 0. ... exDf6? 1. b4! Immediate draw according to DR rule, since Black can't prevent stalemate. So Black can't castle.
