1. c2c4  1... g8f6  2. b1c3  2... e7e5  3. g2g3  3... f8b4 The Reversed Rossolimo Sicilian. 4. e2e4 A  move that White needs anyaway, so why not just play it at once? The  original Bulgarian IM Bogomil Andonov often played like this with reversed colors. 4... b4c3  5. d2c3  5... d7d6  6. f2f3  6... c8e6  7. g1h3  7... a7a5 This is already a novelty and no wonder: the position is quite fresh. 8. a2a4  8... e8g8  9. b2b3  9... b8a6  10. h3g5  10... e6d7  11. c1e3  11... a6c5  12. a1a2  12... a8a6 Aronian is searching for concrete counterplay, and rightly so! 13. a2d2  13... a6b6  14. e3c5  14... d6c5 However, now there might be a problem along the d-file. 15. f1h3  15... h7h6  16. h3d7  16... h6g5 Nothing serious so far. Black had  calculated the lines carefully. 17. h2h4  17... b6d6 Lowering the pressure along  the open file. The drawback of the move is that it creates a potential  weakness on d6. 18. d2d6  18... c7d6  19. d7f5  19... f6h5  20. e1f2  20... g7g6 Logical and obvious. 21. f5g4  21... h5f6 The best defense. 22. d1d2  22... f6g4  23. f3g4  23... g8g7  24. h4h5  24... f8h8 Aronian decided to defend passively and this will prove wrong at the end of the day. 25. f2e2 Black's position is far more unpleasant than it seems. Aronian  needs to constantly watch out for attacks along the d-, f-, and the  h-files as well as queen entries via the d5 square. Looking after so many  weaknesses is simply impossible when there's also a time deficit. 25... f7f6  26. e2d1 Carlsen sends the king in safety and frees the communication  files for his major pieces. 26... d8d7  27. d2e2  27... b7b6  28. e2f3  28... h8h6  29. d1c2
