White wins with 48.Rh1+ Rh5 49.Qb5!
Also winning, according to Stockfish10 and Komodo10, is 48.Bf7, eg 48...Qd8 49.Qh2+ Kg7 50.Be6 Bf6 51.Rh1 Kf8 52.Qh6+ Ke7 53.Rf1 Qh8 54.Qxh8 Bxh8 55.Rf7+ Ke8 56.Rd7, although this is neither so clear nor so pretty as the engines' first line.
The game saw 48.Rf7+? Rg7 49.Rxg7+?! (White is slightly better, according to the engines, after 49.Qh2+ Kg6 50.Rf1) Kxg7 50.Qxg4+ Qg6 ½–½
My final score of +1=2-2 saw me lose 5.6 Fide elo and was an ECF grading performance of 167.8.
