Here's an entertaining online game I just won, playing black. After two nice sacrifices, I almost blew it.
The comments are entirely mine. The engine didn't agree with everything I said, but I'm not going to mention any of that because I want to give the readers a chance to question my conclusions.

1. e4 c5 2. Nf3 Nc6 3. Bb5 e6 4. Bxc6 {Yay - I get the mass of center pawns.} bxc6 5. O-O d6 6. c4 Nf6 {Oops - I am just learning this opening, so I forgot to be careful about allowing e5 which makes black's pawns ugly.} 7. Re1 e5 { Whew} 8. h3 Be6 9. b3 h6 {Probably unnecessary. I can just retreat my B if he plays Ng5.} 10. Nc3 Be7 11. Bb2 {Very slow. A plan with d3, N-somewhere and f4 would at least make black take notice.} O-O 12. d3 Ne8 13. a3 Rb8 {To slow down b4 a bit.} 14. Rb1 f5 15. exf5 Bxf5 16. Ne4 {White got a square for the N, but at the cost of making d3 weak.} Qd7 17. Ng3 Bh7 18. Bc3 Nc7 {With the idea of ...Ne6-d4, or -f4.} 19. b4 cxb4 20. axb4 Ne6 21. d4 {I wish I could say I saw the hanging Rb1. At least then I could claim to have deep positional insight about how my Bh7 was so great I didn't want to trade it.} exd4 22. Nxd4 Nf4 {Right after I sent this move, I saw ...BxR. But the attack after this move was fun.} 23. Ra1 {He must heard my thoughts through the internets.} Bh4 { Threatens 24...Nd3 25.Re2 Nxf2 26.Rxf2 Bxg3. White blocks the f-file to squelch my Rook.} 24. Nf3 Bxg3 {Committing to the sac on the next move. It seemed much better than meekly retreating the B.} 25. fxg3 Nxh3+ {Now if 26. gxh3 Qxh3, I expected something like 27.Re3 guarding the N. Then 27...Qxg3+ and figure out how best to bring other pieces in.} 26. Kh2 {White coughs up a pawn rather than suffer the Q infiltration.} Nf2 {Obviously, black will try this instead of ...Ng5 if he thinks he can get away with it.} 27. Qd4 {He missed the next shot, although I still had to think a bit to bring down the defenses even with this gift.} Rxf3 {! With the point that 28.gxf3 Qh3+ 29.Kg1 Qxg3+ 30.Kf3 Bd3+ is curtains.} 28. Re6 {A fascinating desperation move that throws a wrench into the gears. After lengthy thought, it seemed best to un-hang the Rook and get rid of white's B that's creating the mate threat. It's risky. The more prudent choice is ...Rf7.} Rxc3 29. Rxd6 {?? Oh no. 29.Rxa7! was a better try, creating a latent mate if the Q moves, and setting the trap 29...Rxc4?? 30.Qxc4! Qxa7 31.Re8#. 29...Rb7? looks risky because of the back rank, so black's only way to keep the win may be the drastic 29...c5.} Qf5 {! I really liked this move. I had worked out a nice attacking finish if he takes the R. White pulled the punk card.} 30. Qxc3 Ng4+ 31. Kg1 {Or 31. Kh1 Qh5+ 32. Kg1 Qh2+ 33. Kf1 Qh1+ 34. Ke2 Re8+ 35. Kd2 Qxg2+ 36. Kc1 Re1+ 37. Qxe1 Qc2#} 31... Qf2+ 32. Kh1 Be4 33. Rg1 Bxg2+ 34. Rxg2 Qf1+ 35. Rg1 Qh3#
