1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4 Praggnanandhaa is a great specialist in the Italian Opening, with excellent wins with both colors. 3... f8c5  4. d2d3  4... g8f6  5. e1g1  5... d7d6  6. c2c3  6... a7a6  7. f1e1  7... c5a7  8. b1d2  8... e8g8  9. d2f1  9... c6a5  10. c4b3  10... a5b3  11. a2b3 This opening is a little shocking. When I was a kid, my trainers told me never to let a knight capture my light-squared bishop in the Italian or in the Spanish. Time passes and new ideas appear, but is the old wisdom wrong $2 The position doesn't seem too scary for Black, although White's side has already been defended by several elite GMs, including the legendary Vishy Anand. 11... h7h6 Always a useful move, preventing the pin with Bg5. 12. f1g3  12... f8e8  13. h2h3 To be quite honest, I don't really know what White has in exchange for the very powerful light-squared bishop. For now, he is heading toward the traditional plans, playing Be3 or maybe Nh2-Qf3-Ng4 and trying an attack on the kingside. 13... b7b5 Black expands the queenside and prepares the development of the bishop on b7, a good diagonal, despite leaving the f5-square weakened. To protect the king, Black relies on the traditional rook move to e6, reinforcing the defense through the sixth rank. 14. b3b4  14... c8b7  15. f3h2  15... d6d5 It's a natural reaction to break in the center and seek life for the bishops. 16. d1f3  16... e8e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] 17. g3f5  17... g8h7  18. f3g3  18... f6e8 A move that requires accurate calculation, something that Gukesh certainly isn't lacking. 19. h2g4  19... d5e4  20. d3e4  20... e8d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] It's scary to leave the g7-square unprotected, but in chess the best thing is not to see ghosts and believe in the calculation. 21. g4e5  21... d6f5 [%c_effect f5;square;f5;type;Mistake;persistent;true] This is a big mistake that puts Black in trouble. Black has good play with three queen moves. 22. e4f5  22... e6f6  23. c1e3  23... a7e3  24. g3e3  24... f6f5  25. a1d1  25... d8f6  26. f2f3 White has a big advantage here. His last move reduced the bishop's potential, and he is now ready to penetrate on the seventh rank. In some cases, the knight can find a very strong square on c5. The rook on f5 is misplaced and in trouble. 26... h6h5  27. g1h2 A good prophylactic move. 27... b7c6 Protecting the d7-square. 28. e5c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] 28... f6c6  29. e3e7 The difference in the activity of the heavy pieces is notable. 29... a6a5  30. b4a5  30... a8a5  31. e1e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] 31... b5b4 The best chance. 32. e5a5  32... f5a5  33. e7b4  33... a5e5 White has a clean extra pawn, and on a good day Praggnanandhaa would have no trouble converting his advantage. 34. b4f4  34... c6e6  35. d1d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] 35... e5f5  36. f4c7  36... e6e2  37. d7e7  37... e2d2  38. h3h4  38... f5f4  39. c7e5  39... f4h4  40. h2g3  40... h4h1  41. e5e4  41... h7h6  42. e4f4  42... d2f4  43. g3f4  43... g7g5 Yet another example of how difficult rook endgames are. Every chess player who aspires to mastery has to make a serious study of this type of ending, and even that will not save him from eventual frustrations. 44. f4g3 [%c_effect g3;square;g3;type;Mistake;persistent;true] 44... f7f5 Black has enough counterplay for a miracle draw. 45. e7e6  45... h6g7  46. g3f2  46... h1b1  47. e6e2  47... f5f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 48. e2d2  48... g5g4  49. g2g3  49... h5h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] The only drawing move. 50. g3h4  50... g4g3  51. f2g2  51... b1c1 [%c_effect c1;square;c1;type;GreatFind;persistent;true] Again the only move. Black has to stop White's pawns from advancing. 52. g2h3  52... c1h1  53. h3g4  53... h1h2  54. d2d1  54... h2b2  55. g4f4  55... g3g2  56. d1g1  56... b2c2  57. f4g4  57... g7h6  58. f3f4  58... h6g6  59. c3c4  59... c2c4  60. g1g2 The rook endgame with the f- and h-pawns is a theoretical draw, very well explained by chess literature since the classic endgame book written by Smyslov and Levenfish, studied by generations of chess players. Nowadays, the modern classic is Dvoretsky's Endgame Manual, where the theory of this endgame is well explained and checked by computers. Gukesh defends smoothly and makes everything look easy. 60... c4c1  61. h4h5  61... g6h6  62. g2e2  62... c1g1  63. g4f5  63... g1a1  64. e2e8  64... a1a2  65. f5g4  65... a2g2  66. g4f3  66... g2a2  67. e8e5  67... a2a1  68. e5b5  68... a1a2  69. b5c5  69... a2a1  70. c5e5  70... a1a2  71. f3g4  71... a2g2  72. g4f5 White cannot make progress without losing the h-pawn. 72... g2f2  73. f5e4  73... f2a2  74. e4f3  74... a2a1  75. f3g4  75... a1g1  76. g4f5  76... g1f1  77. e5e4  77... f1a1  78. f5f6  78... h6h5  79. f4f5  79... a1a6  80. e4e6  80... a6a7  81. e6d6  81... h5h6 This is another well-known theoretical endgame. 82. d6b6  82... h6h5  83. b6e6  83... h5h6  84. e6e5  84... h6h5  85. e5e7  85... a7a6  86. f6g7  86... h5g5  87. e7f7  87... a6b6  88. f5f6  88... b6a6  89. f7e7  89... a6f6  90. e7e5
