1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. e2e3  4... b7b6 Less played than 4...0-0 or 4...c5, but still with a gigantic theory, like all the lines of this classic Nimzo-Indian line. 5. g1e2 A logical move, which has the idea of ​​playing a3 and then taking with the knight on c3. 5... f6e4  6. c1d2 Preserving White's good pawn structure. The same can be achieved with 6.Qc2, a popular alternative that has been played by Arjun himself. 6... e4d2 Better to take a bishop than a knight, at least in this position. 7. d1d2  7... e8g8  8. a2a3  8... b4e7  9. g2g3 Developing the bishop on g2 is a natural idea, although White has to be careful after Bb7. 9... c8b7  10. e3e4  10... b8c6 Black prepares to challenge the white center, either by playing …e6-e5 or with Na5 attacking the c4-pawn. 11. d2d3 A new and good move. 11... b7a6 The start of a completely crazy plan. 12. b2b4  12... e7b4 The only justification for the previous move, but even so it is better to just return the bishop to b7. 13. a3b4  13... c6b4  14. d3b1  14... c7c5 Arjun made a mistake in his judgment when he entered this position, as his compensation isn't enough. He is an elite player who, unlike his peers, plays a lot of open tournaments and is used to taking risks to win games with Black. This time, however, I think he overdid it. 15. a1a6 There was no need to return material. 15... b4a6  16. d4d5  16... a6b4 Now we have a material imbalance of bishop and knight against rook and two pawns, with a complex position with chances for both sides. White still has some advantage, but the position has become difficult to play. 17. f1g2  17... e6d5  18. c3d5 This move is debatable. 18... b4d5  19. e4d5  19... f8e8  20. b1d3  20... b6b5  21. e1g1  21... b5b4 Black has managed to create two dangerous passed pawns that are ready to advance. 22. d5d6 The only move. It's important to create counterplay before Black plays d7-d6. 22... a8b8  23. e2f4  23... d8f6  24. d3b3 The position is difficult to play: there are decent alternatives for both sides on each move. White surrenders the d6-pawn, probably not the best idea. 24... f6d6 Black takes one more pawn, but the game continuation shows that things are not so clear. 25. g2d5  25... d6a6 Preventing Ra1. 26. f1d1  26... e8e7 Defending the weak pawns on f7 and d7. 27. g1g2  27... a6a3 Advancing pawns isn't easy, so Arjun proposes exchanging queens, even though this means weakening in the pawn structure. 28. b3b1 An excellent decision. White decides to keep the queens and attempt an attack, taking advantage of the fact that the black queen is far from the kingside. But this means allowing the black pawns to advance. 28... b4b3  29. b1f5 A natural move, but wrong. 29... a3a6 The queen returns to help. 30. f4d3  30... a6f6 Not an easy move, as it offers the exchange of queens, breaking the structure and giving away the c5-pawn. But Black needs to stop white's queen activity. 31. f5f6  31... g7f6  32. g2f3 This loses without a chance. 32... b3b2  33. d1b1  33... b8b3  34. d5e4  34... d7d5 Winning material. 35. c4d5  35... c5c4
