Robson gets the quick knockout anyway on 17…Qc7 18. Nxf7! Kf8? (going down without a fight, though White should still win in the long run on 18…Qxf7 19. Qxd5 0-0 20. Qxc5 Qxf6 21. Qxd4, with a clear pawn to the good and the better position) 19. Nxh8 gxf6 20. Rd3!, a rook lift that leaves Black with no good answer to the threat of 21. Ng6+ Kg7 (Ke8 22. Qxd5) 22. Rg3! Kh7 23. Nf4 Rg8 24. Nxd5 exd5 25. Qf5+ Kh8 26. Qxf6+ and wins.
