1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. c3 Nf6 5. d3 d6 6. 0-0 0-0 7. Bd2? That must have been a mouse slip, as it is very likely that the intended move was 7. Nbd2. In any case, the Bishop does not do anything on d2 and seriously hampers White’s development. Needless to say, such a loss of time can cost very dear, especially in open games. 7. ... a6 8. Bb3 Re8 9. h3 h6 10. Re1 Be6 11. Bxe6 Rxe6 12. Nh4 d5 13. Nf5 Ne7 14. Nxe7+ Qxe7 15. Be3 Rd8 16. Bxc5 Qxc5 17. Nd2 dxe4 18. dxe4 Red6. White did her best to make of necessity virtue, but, to be sure, Black stands much better, as her Rooks dominate the d-file. 19. Nb3 Qc4 20. Qc2 b6 21. Re2

21. ... Qa4. Now and afterwards Black very probably had to play more energetically. For instance: 21. ... Nh5! 22. g3 Qe6 23. Kh2 Rd3 with a crushing advantage. 22. Rae1 c5 23. c4 Nh7. Eventually heading to d4, via g5 and e6. 24. Nc1 Qxc2 25. Rxc2 Ng5 26. f3 Ne6 27. Ne2

27. ... Rd1. This helps White relieve pressure. By 27. ... Rd2 28. Rec1 R8d3 she would firmly hold her grip on White’s position. 28. Rxd1 Rxd1+ 29. Kf2 g5. A tacit offer of peace. 29. ... Nd4 30. Nxd4 exd4 was Black’s last best bet to keep playing for a win. 30. Nc3 Ra1 31. a3 Nd4 32. Rd2 Rc1 33. Na4 b5 34. Nxc5 Rxc4 35. Nd7 Nc6 36. Nf6+ Kg7 37. Ng4 h5 38. Ne3 Rc1 39. Nf5+ Kf8 40. Rd7 Ke8 41. Rc7 Rc2+ 42. Kf1 f6 43. Ne3 Rc1+ 44. Kf2 Kd8 45. Rf7 Rb1 46. Rxf6 Rxb2+ 47. Kf1 Kd7 48. Nd5 a5 49. Nb6+ Kc7 50. Nd5+ Kd7 51. Nb6+ Kc7 52. Nd5+ Kd7 ½ : ½.
