1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. d2d4  3... c5d4  4. f3d4  4... e7e5  5. d4b5  5... d7d6  6. c2c4  6... f8e7  7. b1c3  7... a7a6  8. b5a3  8... c8e6  9. a3c2  9... a8c8 Not the main line. 10. f1e2  10... c6a5 Cori wants to generate queenside play before he castles, but  this might be a risky strategy here. 11. b2b3  11... b7b5  12. c2e3  12... b5c4  13. e3d5 Only energetic play can refute  Black's idea. This move is a novelty and reveals some problems behind  Cori's set up. 13... g8f6  14. c1e3 Be3-b6 is a huge threat and Black needs to initiate some trades. 14... e6d5  15. c3d5  15... f6d5  16. d1d5  16... e8g8  17. e1g1  17... c4b3  18. e2a6  18... c8c3  19. f1b1 Wonderfully played! Nihal spots that the c3 rook is in  danger. 19... a5c6  20. b1b3 White wants to keep a passer along the a-file as then his bishop may support it all the way up to the promotional square. 20... c3b3  21. d5b3  21... c6d4 Cori decided to defend a gloomy position with  opposite-colored bishops on the board. 22. e3d4  22... e5d4  23. a6c4 Black is in trouble. His bishop is significantly  underperforming in comparison to its counterpart and the a-passer is a  monster. 23... d8a5  24. g2g3  24... e7g5  25. g1g2  25... g7g6  26. c4d5  26... a5c3  27. a1d1  27... g8g7  28. d1d3  28... c3c5  29. a2a4  29... g5d8  30. b3b2  30... d8b6  31. d3b3 For a moment White hesitates. 31... b6a5  32. b3d3  32... a5b6  33. h2h4 Finally Nihal finds the right plan. The major weakness in the  position is the black king and the h-pawn puts it in great danger. 33... f8c8  34. b2e2  34... b6a7  35. h4h5  35... c5c1  36. e2g4  36... c8c7  37. d3f3  37... d4d3 Cori finds the only way to defend against the immediate  mate. 38. g4h4  38... a7d4  39. f3d3 Safe play. 39... g6g5 This weakens the king. 40. h5h6  40... g7f8  41. h4h5 Nihal is almost there with Rd3-f3 as a decisive threat. Cori  finds one last chance: 41... d4f2  42. d3f3 ...which is nicely  parried by White. Initiative is everything in the opposite-bishop attacks.  42... c1g1  43. g2h3  43... g1h1  44. h3g4  44... h1h5  45. g4h5  45... f2d4  46. a4a5 Now the pawn moves and it is over in a few moves. 46... c7a7  47. a5a6  47... f7f6  48. f3a3  48... f8e7  49. h5g4  49... e7d8  50. d5b7 The rook is out of the game. Nihal calmly prepares the final blow. 50... d4c5  51. a3b3  51... d8e7
