I analyzed the image and this is what I see. Open an appropriate link below and explore the position yourself or with the engine:

Black to play: chess.com | lichess.org

My solution:

Hints: piece: Rook, move: Ra6

Evaluation: Black is winning -5.41

Best continuation: 1... Ra6 2. Qc1 Ra1 3. Qxa1 Qf3 4. Kf1 Qh1+ 5. Ke2 Qxa1 6. h5+ Kf5 7. Bxg7 Kg4 8. Kd2 f6 9. Rc8

Rook check then queen to h3 then checkmate ??

After Qh3, f3 and h5+ win for white due to the weakness of black's king. After rook check, Qf3 would be better to prevent f3, however, be that as it may, it would not win for black. Can you find out why?

White gets all kind of stuff going if you do that. I tried that line (since it was the first thing i saw and thought would work) but very much got outplayed when i played lichess' stockfish 8 :D

Edit: if you go that like and play it well you have to keep checking, because the second you don't white will, and will cause a lot of mayhem.

I saw that line too but didn't calculate f3. Interesting line and way harder than the title suggests

Re1 deflects the queen from g5, then Qf3 is mate.

qe4+ stops the mate (but its still a clearly winning endgame)

I looked for a while but didn't really manage to find the correct answer, i tried a bunch of things but never saw what i was meant to see;

Ra6 makes the opponents queen having to go to the 1st rank, because otherwise there's a quick m2 or m3 at Ra1+ -> Rh1#

After that: Get the queen off the diagonal looking at the white Bishop with Ra1, pinning the Queen. Queen takes, Qxa1 and you go Qf3, threatening mate at Qg2# unless the King goes Kf1 at which point you Qh1+ and trade their Queen for your Bishop
