Arjun decided to resign instead of trying to find a move in this sad position. A possible continuation is
1. c2c4  1... e7e6  2. g2g3  2... d7d5  3. f1g2  3... g8f6  4. g1f3  4... d5d4  5. e1g1  5... b8c6  6. d2d3  6... f8c5 A popular line among the elite nowadays. Nepomniachtchi was knocked out of the World Cup by Vidit in this variation. 7. b1d2  7... e8g8  8. d2b3  8... c5e7  9. e2e3  9... d4e3  10. c1e3  10... a7a5  11. h2h3 A useful move, preventing ...Ng4. 11... a5a4  12. b3d4  12... c6d4  13. f3d4  13... c7c6 [%c_effect c6;square;c6;type;Inaccuracy;persistent;true] A new move and not a very good one, since it's a bit passive. 14. d4f3 [%c_effect f3;square;f3;type;GreatFind;persistent;true] The knight returns and makes way for the advance of the d-pawn. 14... d8a5  15. d3d4 White has a dream position from the opening. He has more space and his bishops are much better than Black's. 15... f8d8  16. d1c2  16... h7h6  17. a1d1  17... c8d7  18. f3e5  18... d7e8  19. a2a3 A typical blitz move: it's not clear if it's useful, but it doesn't compromise anything. 19.Rfe1 is very natural and the more direct 19.c5 is also good. 19... a8c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true] 20. e3d2 [%c_effect d2;square;d2;type;Interesting;persistent;true] 20... a5a6  21. d2c3  21... b7b5 [%c_effect b5;square;b5;type;Inaccuracy;persistent;true] This leaves Black without any counterplay. 22. c4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] This gives away the d5-square, but White has a big space advantage and can prepare an offensive on the kingside. 22... f6d5  23. f1e1  23... c8b8  24. e5d3  24... e7f6  25. g1h2  25... a6a7  26. c2c1 Nepomniachtchi is not in a hurry. 26... e8d7  27. d3b4  27... d7e8  28. g2e4 White's idea is to play, at some moment, Bb1-Qc2. 28... d5b4  29. a3b4  29... a7e7  30. e4b1  30... e7f8  31. d1d3  31... d8d5  32. e1e4  32... b8d8  33. c1c2  33... g7g6  34. b1a2  34... d5d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] The final mistake, and now White wins by force. 35. e4f4  35... f6g5  36. f4f3  36... f8e7  37. h3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] 37... g5f6  38. f3f6  38... e7f6  39. d4d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 39... f6f5  40. d5d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] White's position is worthy of a picture. Black's dark squares are very weak and the bishops point to the opposing king. The material disadvantage is not felt, as the black rooks can barely move. The plan is Qe2, followed by Rf3. 40... f7f6  41. c2e2  41... e8f7  42. d3f3 The f-pawn is lost. 42... f5g4  43. c3f6  43... d8e8  44. f6e5  44... g4b4  45. e2e3  45... g8h7  46. f3f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Sending the queen away. 46... b4a5  47. a2b1 [%c_effect b1;square;b1;type;GreatFind;persistent;true] The bishop keeps pointing at the king. 47... a5d8  48. h4h5  48... e8g8
