Logical try 8.Rd3+? Kc4 9.R3d4+ Nxd4 10.Rxd4+ as main, but without black knight on the board – position X1, so black king goes to 7-th rank and captures with the rook avoiding stalemate : f.e. 10…Kc5 11.Rd5+ Kc6 12.Rd6+ Kc7 13.Rc6+ (13.Rd7+ Rxd7) 13…Kb8 14.Rc8+ Kb7 15.Rb8+ Kc6 now, after white was forced to leave d-file, the king goes to g-file (the winning plan appeared before in Kling & Horwitz, 1951) 16.Rb6+ Kd5 17.Rd6+ Ke4 18.Re6+ Kf3 19.Rf6+ Kg4–+
