It was not too obvious; It took some trial and error to find. 1..Rxg2+!! 2. Kxg2 Rg8+ Now there are two lines: a) 3. Kh2 b) 3. Kf1 The first line is the nice one: 3. Kh2 Qf4+ 4. Kh1 Ng3+ 5. Kg2 Nxe2 6. Kg1 Nxc1 With an overwhelming material advantage plus possible mating traps. The second line is simpler than the first: 3. Kf1 Ng3+ 4. Ke1 Nxe2 5. Rxe2 Qxb3 or 5..Qxf3 and Black has a clear winning advantage.
To wrap it up I want to add two more small lines: On 1..Rxg2 Instead of 2. Kxg2 what happens if the King goes to h1 or f1. So 2. Kh1 Nxf2+ 3. Kxg2 Qxe2 wins for Black. And 2. Kf1 loses to 2..Rxf2+
only one move that puts the white king in check without sacrificing a queen…

This is a repeat
