1. e2e4  1... c7c5  2. g1f3  2... e7e6  3. c2c3 An interesting opening choice by Aronian. 3... d7d5  4. e4d5  4... d8d5  5. d2d4  5... g8f6  6. b1a3  6... b8c6  7. c1e3  7... c5d4  8. a3b5  8... d5d7  9. b5d4 In this line White is aiming for a slight opening advantage, thanks to his queenside majority. 9... a7a6  10. f1d3  10... f8d6  11. e1g1  11... c6e7 "I was really happy I got a fight out of the opening." (Caruana) Black wants to preserve as many pieces as he can. 12. d1c2  12... e8g8  13. e3g5  13... e7g6 Black is OK with the doubled kingside pawns as  long as the knight is around to shield the king. 14. a1d1  14... d7c7 "I kind of liked my position. I felt like I had a lot of potential here. I also had  more time on the clock; he was hesitating a lot." (Caruana) 15. f1e1  15... c8d7  16. g2g3  16... f8e8  17. g5f6  17... g7f6  18. h2h4 However, Aronian is also happy with the  weakened black kingside and launches an immediate attack. 18... g8h8  Too ambitious. Black is downplaying the opponent's threats. 19. c2d2  19... d6f8  20. h4h5  20... g6e7 Caruana was very proud of this maneuver but missed Aronian's  next move: 21. d3c2 "I need one move basically. If I can get Re8-d8  and Qc7-c5, my position is amazing." (Caruana) Qd2-d3 is a strong threat,  and if f6-f5, White can simply capture the pawn with the knight. 21... e8d8  22. d2d3  22... f6f5 At this point Aronian thought that he was close to  winning. (Caruana) And he was right! 23. g3g4 "A very surprising move."  (Kramnik) "I was very happy to see this. I thought it was not a good  move." (Caruana) 23... f7f6 "I stopped considering other moves. It was a direct,  positional choice to stop Nf3-g5." (Caruana) 24. g4g5 "This feels wrong."  (Caruana) 24... c7f4 Now Black is safe and is playing for a win. On top of  this, Aronian was very low on time. 25. g5f6  25... f4g4  26. g1f1  26... g4h3  27. f1e2
