Black try to open line towards white's king but probably preparing it with 17... a5 first is more accurate.
18. axb4 a5 19. bxa5 Rxa5 20. Nh4 Nhf8 Black can't win a pawn with 20... Nxg5 ?! because after 21. Nxg6 fxg6 22.h4! Nh3 23. Rxg6 White's regain the pawn back with advantage.
21. f4 Qa7 22. f5 exf5 22... Rxa2 doesn't cause white much problems for e.g. 23. Nxa2 Qxa2 24. fxg6 Nxg6 (24...Qa1+ 25. Kc2 Qa4+ 26. Kb1) 25. Nxg6 fxg6 26. Rdf1 Black's king is much in danger compare to white's king.
23. exf5 Bxf5 24. Nxf5 Rxf5 25. Rdf1 g6? This further weaken black's kingside.
26. Rxf5 gxf5 27. Qd3 27. Re1! is stronger for e.g 27... Nb6 (27... Ng6 28. Qc4 Attacking both f7 and c6) 28. Qe5 Rh7 29. Qc5 Ng6 30. d5 Nc8 31. Qxa7 Nxa7 32. d6
27... Ne6? 28. Qxf5 Stronger is 28. g6!1 Nd8 29. Qxf5 And black's position collapse.
28... Nxd4 29. Qxf7+ Kd8 30. Re1 Qc5 31. g6 Ne5
32. Rxe5! Qxe5 33. g7 Re8 34. Qxe8+ Kxe8 35. g8=Q+
White's is a piece up.
35...Kd7 36. Qg6 h4 37. Qg4+ Kd8 38. Qe4 Qf6 39. Bc4 Bd6 40. Qd3 Qg7 41. Be3 Be5 42. Ne2 c5 43. b4! Kc7 44. bxc5 Nxe2+ 45. Qxe2 Qg3 46. Qf2 Qxh3 47. Qf7+ Qd7 Other move will lead to checkmate for e.g. 47... Kc6 ?? 48. Bd5+ Kb5 49. Qb7+ Ka4 (49... Ka5 50. Qb6+ Ka4 51. Bc6+ Ka3 52. Qa5+ Kb3 53. Bd5#) 50. Qa6+ Kb4 51. Qb6+ Ka4 52. Bc6+ Ka3 53. Qa5+ Kb3 54. Bd5#) (47... Kb8 48. Qe8+ Ka7 49. Qe7+ Kb8 50. Qxe5+
48. Qxd7+ Kxd7 49. Bf1 Black's h-pawn was safely block.
49...Kc6 50. Bg2+ Kb5 51. Kd2 Kc4 52. Ke2 Bc7 53. Bf2 Bd8 54. Kf3 Kb5 55. Kg4 Be7 56. c6 Bd8 57. Bxh4 1-0.
Black resign because after for e.g 57... Bb6 58. Bg3 Ka6 59. c7 Bxc7 60. Bxc7 black will lose.
