1. e4 c5 2. c3 d5 3. exd5 Qxd5 4. d4 Nf6 5. Nf3 e6 6. Na3 a6 7. Nc4 Nbd7 8. Be3. Pretty dubious, indeed.

15. Bxb5 Bxe3 16. Qd3 Bb6
17. Rd1? A mistake which loses a Pawn. The comparatively best is 17. Qc4! Qxc4 18. Bxc4 Bb7! 19. Bb5! Bxa5 20. bxa5 Ke7 21. 0-0 Nc5 with more or less equality.
17. ... Bxa5 18. bxa5 Rxa5 19. c4
17. ... Bxa5 18. bxa5 Rxa5 19. c4
19. ... 0-0! The pointe: if now 20. Bxd7 then 20. ... Rd8 recovering the piece with at least one Pawn ahead.
20. 0-0 Nc5 21. Qe3 Bb7 22. Rd2 Bxf3 23. Qxf3 h6 24. h3 Qe5 25. Re2 Qd4+ 26. Kh1 Ra1 27. Ree1 Rxe1 28. Rxe1 Rd8 29. Rf1 f5 30. Re1 Ne4 31. Bc6. Perhaps White should have sought to somehow arrange an exchange of Queens, because, as things go now, Black meets no obstacles in consolidating her material advantage.
31. ... Nf2+ 32. Kh2 Qd6+. Or 32. ... Qxc4 32. Qxf2 Qxc6 remaining with two Pawns ahead.
33. Kg1. Again, if 33. Qg3 then 33. ... Qxc6 34. Qxf2 Qxc4 with two Pawns to the good.
33. ... Nd3 34. Rd1
20. 0-0 Nc5 21. Qe3 Bb7 22. Rd2 Bxf3 23. Qxf3 h6 24. h3 Qe5 25. Re2 Qd4+ 26. Kh1 Ra1 27. Ree1 Rxe1 28. Rxe1 Rd8 29. Rf1 f5 30. Re1 Ne4 31. Bc6.

33. Kg1. Again, if 33. Qg3 then 33. ... Qxc6 34. Qxf2 Qxc4 with two Pawns to the good.
33. ... Nd3 34. Rd1
34. ... Qc5+. 34. ... Ne5! at once is decisive.
35. Kh2 Qxc4 36.Bb7 Kh7! 37. Bc6? Ne5! 0–1.
35. Kh2 Qxc4 36.Bb7 Kh7! 37. Bc6? Ne5! 0–1.
