1. e2e4  1... c7c6  2. d2d4  2... d7d5  3. e4d5  3... c6d5  4. f1d3 Fifty years ago R. Fischer revived  this line in his games versus the former world champion T. Petrosian. The  Carlsbad pawn chain is extremely popular nowadays, namely thanks to the  rise of the closed systems like the London one. 4... g8f6  5. h2h3  5... g7g6  6. g1f3  6... c8f5  7. d3e2 White correctly leaves the opponent's bishop on the  board as it might be a concern for the second player in the long run. 7... b8d7  8. e1g1  8... e7e6 Bf5 is left out but is obviously vulnerable. On top of that,  Aronian did not castle yet. 9. c1f4  9... d8b6  10. b2b3  10... g6g5 A creative try by Aronian! In the age of computers, when  human players are mocked for every different move, it takes a lot of  courage to play creatively! 11. f4g5  11... f6e4  12. g5h4 Tari is also aggressive and prevents the opponent's  castling. The bishop on h4, however, is more vulnerable than it seems. 12... h8g8  13. g1h1  13... e6e5 The only logical follow-up! The queen is  entering the battle with huge effect. The strongest black piece gains  access to both the sixth rank and the f2-pawn, and Aronian launches an  immediate attack against the white king. 14. d4e5  14... b6g6 Only here did Black go astray. 15. f1g1  15... f8c5  16. d1e1 Tari defends in time. 16... a8c8  17. b1d2 And consolidates. After the active black pieces are traded,  White would be simply two pawns ahead. 17... g6b6  18. d2e4  18... d5e4  19. f3h2 A solid human choice. 19... d7e5  20. a1d1 Bringing more and more pieces out. 20... b6h6  21. h4g3 Again the simplest and most solid choice. 21... g8g3 The last chance to get some play, but it is too late. 22. f2g3  22... c5g1  23. e1g1  23... h6b6  24. g1f1  24... f5g6  25. f1f4 Tari gave away one of his  pawns but defended everything and now has positional advantage besides the extra pawn. The only problem for the Norwegian GM was his clock situation.  25... f7f6  26. h2g4  26... e5g4  27. e2g4  27... c8d8  28. d1f1 A step in the wrong  direction. White needed to swap the rooks. 28... b6d6  29. f4h6  29... d6e5  30. h6g7 This seems like a winning move, but it is based on a wrong assumption. 30... e5e7  31. g7g8  31... e7f8  32. g8c4  32... f8e7  33. c4g8  33... e7f8  34. g8c4  34... f8e7  35. g4f5  35... e8f8  36. c4c3  36... f8g7
