1.Rf7 Rd8 No move 1…O-O-O!? In the initial position it is White’s move. Before this move was made by black: black pawns had not yet moved, then either the king or the black rook was in play. This means that castling is impossible!
2.Rf8+ Ke7 3.Rxd8 Kxd8 4.Kf7!
4.Kf8? Kd7! 5.Kf7 Kd6–+
4…h5 5.e5 h4 6.e6 h3 7.e7+ win.
A study with a retroanalysis of the impossibility of castling.
