comment: Arjun misses a good winning chance.
context: 1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... d7d5  4. d1b3 Arjun and Vachier-Lagrave are two creative and aggressive players. A no-holds-barred battle was expected, and they didn't disappoint. They have different styles of opening play: while Arjun can try anything, Vachier-Lagrave sticks to his favorite openings. The theoretical battle starts early—the move 4.Qb3 is not very popular. 4... d5c4  5. b3c4  5... c8e6 This is the way to exploit White's move order. 6. c4b5  6... e6d7  7. b5b3  7... c7c5 This move is the basis of all of Black's counterplay in the Grunfeld defense. 8. d4d5  8... b7b5 Sacrificing a pawn to exploit the lead in development. White's opening strategy looks a bit dubious. 9. e2e4 Arjun refuses the pawn. 9... b5b4 Black advances the wrong pawn. 10. e4e5 A forced reply. Otherwise, White loses the e-pawn. 10... b4c3 A new move and also an inaccuracy. 11. e5f6 Black's position is difficult now. 11... d8b6  12. g1e2 A creative reaction. 12... b6f6  13. e2c3  13... f8g7  14. f1e2  14... e8g8  15. e1g1  15... d7c8 A good defensive move, preventing ...Qb7 and preparing Nd7 and Ba6. 16. c1e3  16... b8d7  17. b3a3  17... c8b7  18. f1d1  18... f8d8  19. a1c1  19... f6h4 An excellent idea to create counterplay. 20. e2b5 A natural reply, preparing either Bxd7 or Bc6. 20... g7e5 Black has two good alternatives to this move. 21. h2h3  21... e5d6 This allows White to achieve a big advantage. 22. b5c6  22... b7c6  23. d5c6  23... d7e5  24. e3c5  24... e5c4 The game becomes tactical, and Black is on the verge of defeat. 25. a3a6 This move allows Vachier-Lagrave to demonstrate his incredible calculation skills. 25... d6c5  26. d1d8  26... a8d8  27. c6c7  27... d8f8  28. c3e4 What a delightful game. Tactics against tactics. 28... h4e4  29. c7c8q  29... c5f2  30. g1h1  30... c4e3 The Frenchman naturally goes forward, but there's a better route for the knight. 31. c8c6 How cool is writing \"Qcc6\" on the scoresheet $2 31... e4d4  32. a6a4 Exchaning queens is a priority. 32... d4b2  33. a4b3  33... b2d2
