Another famous example
This puzzle reminds me of another famous example. See the following position.
This is position occurred after white’s 47th move in the Tiebreak Rapid of the World Championship Match between Magnus Carlsen and Sergey Karjakin (2016). It is clear that white is winning. He has a material advantage. That’s enough to secure the victory in the match (final game!).
Black played: 47. … Ra2+ The answer is forced: 48. Kh1 (of course not Kg1 and white even loses because off Qf2+ and mate). Black decided to renew the mate threat. More tenacious would have been to swap the queens. But I suspect that Karjakin was in no mood to suffer any longer than necessary. 48. … Qf2.
It is likely that Magnus has foreseen everything. He goes for the kill with 49. Rc8+ Kh7 and 50. Qh6+!!
Black resigned because off: 50. … Kxh6 51. Th8# or 50. … gxh6 51. Rxf7#
