context: 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.
