I played this 15 0 game not too long ago and thought people might enjoy this combination that was played. It requires a little bit of calculation and finding two tricky moves in more than one variation. If you decide to post, post all of your analysis. And don't cheat! 😀 Here are the moves:
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. f4!? Nc6 7. Nxc6 bxc6 8. e5 Nfd7 9. exd6 exd6 10. Be3 Be7 11. Qd4 0-0 12. 0-0-0 Nf6 13. Be2 d5 14. Bf3 Rb8 15. Qxa7 Rb7 16. Qa4 Ng4 17. Bg1 Qc7 18. h3? Rb4! 19. Qa7 Qxf4+ 20. Kb1
Black to play and win. The first move is probably the first move alot of people consider, but finding best moves after that might be a bit tricky. Hopefully this FEN will work.

[fen]2b2rk1/Q3bp1p/2p3p1/3p4/1r3qn1/2N2B1P/PPP3P1/1K1R2BR w - - 0 1[/fen]
Here's the start that I've got so far...
1...Rxb2+!! 2.Kxb2 Qb4+ 3.Kc1 Bg5+ 4.Rd2 Qxc3 5.Qf2?? Qa1#
1...Rxb2+!! 2.Kxb2 Qb4+ 3.Kc1 Bg5+ 4.Rd2 Qxc3 5.Be3 Bxe3 6.hxg4 Qxd2+ 7.Kb1 Qc2#
I really hope I'm not completely off, it's late and I'm not using any analysis boards for help. :/
More....
1...Rxb2+!! 2.Ka1 Rxc2 3.Be3 Qxe3 4.Qxe3 Nxe3 5.Re1 Bg5 -+
and
1...Rxb2+!! 2.Ka1 Rxc2 3.Be3 Nxe3 4.Rb1 Bg5, I had Nc4 here before -+
Rxb2!! is the first important move and after:
Kxb2 Qb4+ Kc1
Bg5+! is the second move. For a while I only looked at Ba3. Anyway, after
..Bg5+ Rd2 Qxc3 Be3?? Bxe3 hxg4?? Qxd2+ Kb1 Bxa7 wins a queen, not entirely sure what Qc2# was about in your variation, although maybe I misread. But what happens after the best move:
Kxb2 Qb4+ Ka1! Qxc3+ Kb1 ?

I posted my lines for Ka1, but I have a suspicion they are either off or incomplete.

The problem is that he still has his dark squared bishop, and it can emerge after:
Rxb2+!! Kxb2 Qb4+ Ka1! Qxc3+ Kb1 Qb4+ Ka1 Bf6+ Bd4
Finding anything here? 😀
1...Rxb2+!! 2.Kxb2 Qb4+ 3.Ka1 Qxc3+ 4.Kb1 Bf5 5.Qa4 Rb8
or 5.hxg4 Bxc2+ 6.Kc1 Bxd1+ 7.Kxd1 Qa1+ 8.Kd2 Bb4+
Alright, so I haven't checked this with an engine, but looked at it for a long time on a board so here goes:
Rxb2+!! Kxb2 (All other don't really make sense) Qb4+ :
Kc1? Bg5+! Rd2 Qxc3 -+
Ka1! Qxc3+ Kb1 Qb4+ Ka1 Bf6+ Bd4 Ne3!! And Black wins in all lines (I think!) Notice that now Rc1?? is simply answered by Bxd4+
