So, I went an looked up the game- I was right- it is a forced mate in 10, but Shtembuliak diverted to a Q vs R+N ending rather than keeping the black king in the mating net- in the line I gave it continued 4....Kg7 5.exf6+? allowing black to give up the queen for the rook to escape mate. White should have played 5.Rh5/4/3 to make room for the white queen on h6- this forces black to start sacrificial delays like 5....Qc5 etc.

I never noticed the edit function until just now!

I think it probably a forced mate after 1.Rg4+ Kh8 2.Qe3 Kh7 3.Rh4 Kg6 4.Rxh6+. Hard to believe the black king can escape mate after this.
