Like Jassi, I would look at the sacrifice of the queen first. My only concern is the line where white might take at f7, but I think black’s king is safe:
1. …..Qh4! 2. Qf7
No better is the capture at h4: [2.Qh4 Rg2 3.Rg2 Rg2 4.Kh1 Rg4 wins a piece outright]. Continuing:
2. …..Kd8 3. Rg1 Qe4 4. Qf6 Kc8 and the black king will eventually find a haven at b8.
1 … Q:h4
2. Q:h4 R:g2+
3. R:g2 R:g2+
4. Kh1 Rg4+
and Black is up B+P
1. … Qxh4! 2. Qxh4, Rxg2+3. Rxh2, Rxh2+ 4. Kh1 Rg4+ 5. Kh2 Rxh4 0-1
1. … Qxh4
2. Qxh4 Rxg2+
3. Rxg2 Rxg2+
4. Kh1 Rg4+
5. Kh2 Rxh4, up one bishop.
2. Qxf7+ Kd8, still threatening
3. … Rxg2+ etc.
Q e7 to h4(X-N)

1…Q:h4 2. Q:h4 (Q:f7+ comes to nothing after Kd8) R:h2+ 3. R:h2 R:h2+ 4. Kg1 Rg4+ and black recovers the Q, ending up netting a piece.
