1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. f2f3 An extremely dynamic, creative and risky opening system, matching Arjun's playing style. 4... c7c5  5. a2a3  5... b4c3  6. b2c3  6... b8c6  7. e2e4  7... d7d6 A typical Nimzo-Indian pawn structure. I've always liked Black in this type of position. 8. g1e2  8... h7h6 This move prevents the pin with Bg5, but for me it's not clear that it's necessary. Black could castle or immediately begin his traditional plan on the queenside with b6-Ba6. 9. a1a2 We saw a similar maneuver in the now famous match game between Ding Liren and Nepomniachtchi. I must admit that I already had difficulty understanding the move in that game and I have even more difficulty understanding it in this one. In fact, I must admit that Arjun's moves in general are incomprehensible to me—perhaps that's why he is my favorite chess player nowadays. 9... d8a5  10. e1f2 [%c_effect f2;square;f2;type;GreatFind;persistent;true] Black was threatening to capture on d4. 10... a5c7 It's open for discussion whether sending White's king to f2 is such a great achievement. The standard presumptions do not apply to this position. 11. d4d5  11... c6e5 This is inaccurate. 12. e2g3  12... e8g8  13. a3a4 Useful to prevent a possible break on b5, which could be dangerous with the white king in the center. Observing breaks in a pawn structure is very important to understand your plan and that of your opponent. The opening was a success for White. 13... c7a5 The queen makes a surprising return to this square. 14. d1c2  14... a5a6  15. a2a3 As I humbly wrote before and reaffirm now: Arjun's moves are difficult to understand, since he plays chess without prejudice. I'd never in a thousand years think about this move. 15... f8e8  16. c2a2  16... a6a5  17. f1e2  17... e5g6  18. h1d1 Considering that Black can close the center, perhaps it would be better to leave the rook on h1 and develop the bishop first, so the h2-h4 advance could be accomplished. 18... e6e5 With the center closed, players can maneuver without haste. White needs to prepare the pawn advance on the king's flank. 19. e2d3  19... f6h7  20. g3f5  20... a5d8  21. g2g3  21... g6e7  22. f2g2  22... h6h5 I don't like this advance. 23. f5e3  23... e8f8  24. a2b1  24... c8d7  25. a3a2  25... h5h4 [%c_effect h4;square;h4;type;Mistake;persistent;true] A serious positional mistake that helps White's attack. 26. e3f5  26... e7f5  27. e4f5  27... d8f6  28. g3g4 [%c_effect g4;square;g4;type;Inaccuracy;persistent;true] This gives Black a good chance to fight back. 28... a8b8 [%c_effect b8;square;b8;type;Mistake;persistent;true] This is a critical moment of the game. 29. d1f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] Black is strategically lost now. 29... g8h8  30. h2h3  30... f8g8  31. a4a5 White is not in a hurry. 31... f6e7  32. a2b2  32... d7c8  33. c1e3  33... e7d8  34. b1e1  34... d8a5  35. f5f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] 35... g7g6  36. b2b5 Another move that would never cross the mind of most chess players. 36... a5a3  37. e3c1  37... a3a1  38. g2h1 Until the end of this analysis I will bother the impatient reader with my admiration for the surprising moves made by White. This is another one of them, and one of the computer's first choices. I suppose a more conventional player would think about taking the h4-pawn straight away. 38... c8d7  39. b5b3  39... a1a5 The queen must go back before it's trapped. 40. e1h4  40... a5d8  41. g4g5  41... d7f5  42. d3e2 Calmly refusing the exchange and keeping an eye on the b5-break, probably the main reason why the bishop didn't go to e4. 42... a7a6  43. f1g1 [%c_effect g1;square;g1;type;Brilliant;persistent;true] Another deep move, the idea of which is related to a rook sacrifice on g4. 43... b7b5  44. c4b5  44... a6b5  45. e2b5  45... d8a5  46. c3c4  46... b8a8  47. b5c6  47... a8b8  48. b3a3  48... a5b4  49. a3a7 [%c_effect a7;square;a7;type;GreatFind;persistent;true] Arjun finds a new way to pose problems to Black's position. Honestly, I cannot praise this game highly enough. 49... b8f8  50. h1h2 Many moves lead to a win, so why not play another mysterious one $2 50... b4c3  51. h4f2  51... e5e4 Desperately trying some counterplay, but now the bishop joins the game. 52. c1f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true]
