Analyze it and show me the variation to confirm this. I'll help get you started with 46.f4 Kf5 47.Rxf7+ Kg4 48.Rf6 Kxg3 49.Rxg6+ Kxh4 (49...Kh3 50.Rxe6 Ra1+ 51.Kf2 Kxh4 52.Re1=) 50.Rxe6 Kg3 51.Re1=; 48...Kh3 49.Rxg3 Rg2+ 50.Kh1 Rxg3 (50...Re2 51.Kg1 and Black has nothing better than 51...Rg2+ again; 50...Ra2 51.Rxe6 Kxg3 52.Re1=) Rxe6 51.Rf3 Re1=. It is not necessary to analyze this so much, but I'm trying to give you plenty to work with. BTW, I'm at work, so this is all "blindfolded" without use of a set. Hopefully, no errors crept in.
