The first is that we won't have time to analyze it in great detail, as it is a world in its own right. The second is that I will have to put some question marks, without the slightest intention of blaming the players who had little time to find difficult details. I will only do this to facilitate study, indicating where errors were made. 47. c1b1 [%c_effect b1;square;b1;type;Inaccuracy;persistent;true] 47... e6c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] 48. h1g1  48... f5d6  49. b1b4  49... b6b5  50. b4d4  50... d6f5  51. d4d8  51... c6b6  52. g1f2  52... b5b4  53. a3b4  53... b6b4  54. d8g8  54... g6f7  55. g8g4  55... b4b2  56. f2e1  56... b2b7  57. e1d2  57... b7a7  58. d3a3  58... a7a8  59. d2d3  59... f7e6  60. d3c4  60... f5d6  61. c4b4  61... a8b8  62. b4a4  62... d6e4 [%c_effect e4;square;e4;type;Mistake;persistent;true] 63. a3e3 [%c_effect e3;square;e3;type;Mistake;persistent;true] 63... e6f5 [%c_effect f5;square;f5;type;Mistake;persistent;true] 64. g4g7  64... e4d6  65. e3b3  65... b8c8  66. b3d3  66... d6e4  67. a4b4  67... c8c1  68. d3d5  68... f5e6  69. d5d4  69... e6f5  70. d4d5  70... f5e6  71. d5d3  71... e6f5  72. g7e7  72... e4f2  73. d3c3  73... c1c3  74. b4c3  74... f2e4  75. c3d4  75... e4g3  76. d4e3  76... g3f1  77. e3e2  77... f1h2  78. e7h7  78... h2g4  79. e2f3  79... f5g6  80. h7h1  80... f6f5 The endgame is winning for White, but it's much more difficult than it seems.
