1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5  3... g7g6  4. e1g1  4... f8g7  5. c2c3 This is what we call the Classical Rossolimo. In the beginning, it was all about White expanding in the center. 5... g8f6  6. f1e1  6... e8g8  7. d2d4  7... d7d5 Black naturally would not give the most vital part of the board without a fight. 8. e4e5  8... f6e4  9. c1e3  9... c5d4  10. c3d4  10... d8b6  11. d1e2  11... c8d7  12. b5a4  12... a8c8  13. b1c3  13... e4c3  14. b2c3  14... b6d8 A brilliant move that defends the bishop, thus preparing the knight maneuver via a5 towards the c4-square, while creating the tactical threats of Nc6xd4! and/or Nc6xe5! 15. a4b3  15... c6a5 Carlsen is strictly following his plan, but this move is surprisingly a novelty. 16. a1c1  16... a5b3 A hefty bishop pair has been acquired… 17. a2b3 at the expense of the improved pawn structure for White. However, one should not forget that pieces almost always have priority to pawns. 17... d8b6 Carlsen is trying to discourage the c3-c4 break, thus gaining stability. 18. e2a2  18... a7a5  19. a2a3  19... f8e8  20. c3c4  20... d5c4  21. b3c4  21... b6a6 At the end of the day, Black would provoke the advance of the c-pawn and this will promise his solid control of the light squares. 22. c4c5  22... d7c6  23. c1b1  23... a5a4 \"I went for a somewhat risky plan here, as I have to spend some time later for Qa6-a8-c8, bringing the bishop back into the game.\" (Carlsen) 24. e1c1 Caruana has two major problems: his two minor pieces... None of them has any prospects—the bishop being particularly bad, but the knight too, does not have any good outposts. Take all the minors away and White would do great, but how to deal with them now? 24... c8d8  25. f3d2  25... a6e2 Black spots a chance and grabs it! The queen is heading toward the kingside. 26. f2f3  26... d8d4 \"The exchange sacrifice was screaming to be played.\" (Carlsen) 27. e3d4  27... e2d2
