Rxd3 h5 21. Ne3 (21. Nh6+ Kf8)
21. ... Nb8 22. f4 Nc6 23. d5 exd5 24. Nxd5 Qe4+ 25. Kf1 Kf8 26. Qb2 Ne7 27. Qa3 Rc5 28. Rd4 Qc2 29. Nxe7 Rxd4 30. Rxd4 Qc1+ 31. Qxc1 Rxc1+ 32. Kf2 Kxe7 33. a4 Ke6 34. g3 Rc2+ 35. Kf3 Rc3+ 36.

21. ... Nb8 22. f4 Nc6 23. d5 exd5 24. Nxd5 Qe4+ 25. Kf1 Kf8 26. Qb2 Ne7 27. Qa3 Rc5 28. Rd4 Qc2 29. Nxe7 Rxd4 30. Rxd4 Qc1+ 31. Qxc1 Rxc1+ 32. Kf2 Kxe7 33. a4 Ke6 34. g3 Rc2+ 35. Kf3 Rc3+ 36.

47. Rb6+ Kd5? A mistake which should lose. The right move was 47. ... Ke7 48. Rf6 (or by transposition 48. Rb7+ Ke8 49. Rxf7 a4 50. Kxg6 a3 51. Ra7 Rxf4=) 48. ... a4 49. Rxf7+ Ke8 50. Kxg6 a3 51. Ra7 Rxf4= with a draw in view.
48. Rd6+? Returning the favour. Now White could win by 48. Rf6! a4 49. Kxf7 a3 50. e6 a2 51. e7 a1=Q 52. e8=Q Qa7+ 53. Kg8 with a position where Black, despite material equality, is helpless against White’s mating attack.
48. ... Ke4 49. e6 fxe6 50. Rxe6+ Kf5 51. Rxg6 Rxf4 52. Rg5+ Ke6 ½ : ½.
48. ... Ke4 49. e6 fxe6 50. Rxe6+ Kf5 51. Rxg6 Rxf4 52. Rg5+ Ke6 ½ : ½.
