1. e2e4  1... d7d5  2. e4d5  2... d8d5  3. b1c3  3... d5d6 The Scandinavian Defense is not often seen in games between two top players, although Carlsen famously beat Caruana with it. Arjun is used to taking risks to unbalance games against lower-rated players when the pressure to win with Black is greater. The variation itself is not that bad; suffice it to say that it has been played several times by Carlsen at different time controls. This line with 3...Qd6 is a specialty of GM Tiviakov, and it's not the first time that Arjun has played it. 4. d2d4  4... g8f6  5. g1f3  5... g7g6 This is Black's fourth most-popular choice. 6. c3b5  6... d6b6  7. a2a4 Threatening a4-a5. 7... a7a6  8. b5a3  8... c8e6  9. a3c4 This is a good and new move. 9... e6c4  10. f1c4  10... f8g7 This move is criticized by the computer, but the alternative the machine offers is depressing, leading to a painful ending for Black, everything Arjun didn't want when choosing this opening line. 11. e1g1  11... e8g8 The computer already gives White a more or less a 1.5 advantage here, which is surprising to me, as I didn't think it was that bad for Black. 12. c2c3 White won't play the next few moves accurately. I think he lacked a bit of energy and subtlety to avoid Black's counterplay. 12... c7c5 An important move to give Black counterplay by opening the diagonal of the g7-bishop. 13. a4a5  13... b6c7  14. d4c5  14... c7c5  15. d1d4 After exchanging queens, Black no longer has any major problems. 15... f8c8  16. f3e5 It is better to move the bishop to b3 or e2. After the move is played, White most likely will end up with an isolated queen's pawn. 16... e7e6  17. a1a4  17... c5d4  18. c3d4  18... b8c6  19. e5c6  19... c8c6 The position is now more comfortable for Black. White has some suffering ahead. The game has remained close to a draw for a long time. 20. c1g5  20... a8d8  21. f1d1  21... d8d7  22. g1f1 It's usually a good strategy to bring the king to the center in an endgame. 22... f6d5  23. f1e2  23... h7h6  24. g5e3  24... d5e7 The knight was fine on d5, but Arjun gets ready to attack the d4-pawn quickly, a more direct play that is his characteristic. I'd have played 25. c4d3  25... c6d6  26. d1d2 Subelj decides to surrender the d4-pawn, an interesting strategy. Black, however, is in no hurry to capture it. 26... f7f5 Just keeping the pressure. 27. d3c4  27... g6g5 Threatening f5-f4. 28. f2f4  28... g5g4  29. a4b4 Subelj decides to activate. The computer likes 29.h4, which is too deep a move to understand, let alone explain.
