Did white play Rd1?
One has to assume time pressure here- otherwise hard to explain missing 1.Rd1 which will win both black pieces.
The threat of mate on h1 is the first place to look: 1. Rd1 Rf5+ 2. Bxf5 Bxf5 3. Kxf5 g3 4. Rd7 g2 5. Rxf7 g8(Q) 6. Rh7+ Kg2 7. Rg7+ K moves 8. Rxg1 Kxg1 9. f7 and a quick promotion.
R-d1
1. Rd1 Rf5+ 2. B:f5 B:f5 3. K:f5 g3 4. Rd7 g2 5. R:f7 g1Q 6. Rh7+ Kg2 7. Rg7+ Kf1 R:g1+ and wins
1. Rd1, threatening Ra1#
The only means Black has to stop it is
1. … Rf5+
2. Bxf5 Bxf5
3. Kxf5 1-0
