1…Kg6+! Black king goes to the safety zone. 2.Kb6!! The point, winning move. C line and sixth rank have to be open for the white queen, so the white king should not be in the way of its queen. 2…Kh7! The field g7 should be free for the black rook. 3.Qc2+! 3.Qd3+? Kh8! 4.Qd6 Kh7! 5.Kc7 Rg7+ 6.Kd8 Rg8+ 7.Ke7 Rg7+ 8.Kf8 Rg8+=
3…Kh8 4.Qc6! The right place for the queen.
Now the effect is visible of 2.Kb6!! [4.Qc8+ Kh7 5.Qc2+ Waste of time
4…Kh7 5.Qe4+! A maneuver with a tempo that leads to an even better position on the 6th rank. 5…Kh8 6.Qe6! Kh7 7.Kc7 Rg7+ 8.Kd8 Rg8+ 9.Kd7 The shortest way to win. 9.Ke7 Kg7] 9…Kg7 10.Ke7 Kh7 11.Kf7 Rg5 12.Kf8 h5 13.Qf6 Rg6 14.Qe5 Again, the shortest way. [14.Qf5 Kh6] 14…Kh6 15.Kf7 Rg4 16.Qh8+ Kg5 17.Qf6#
Recently, Arestov and Kiryakov (12th UAPA 2020) published a study with a visually similar maneuver, but the moves in the two studies, as well as the ending, are different. http://www.problemistasajedrez.com.ar/ 12th-international-internet-tournament-uapa-2020-mt110-francisco-benko/ arestov-kiryakov-sec-a-no1-bview-php/
