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  28. c1d1  28... d2f4 For the exchange, Black already got one pawn and is about to take a second one which, combined with his strong pieces, will promise him an edge. How serious that advantage would be is the question. 29. a3b4 The wrong plan according to the world champion. 29... e7e6  30. d4c3  30... f4b4 \"It's very much in my interest to exchange queens there. My bishops are so strong in the endgame that he stands no chance.\" (Carlsen) Indeed, the strength of the bishop pair increases in the endgame. 31. c3b4  31... g7e5  32. b4a3 For the time being, the white rooks control the open files, but their functions are purely defensive. Whereas Black can soon open a file for his rook as well while protecting all the entry squares. 32... e5f6  33. g1f2  33... f6e7  34. b1b6  34... e8c8  35. d1d2  35... f7f6  36. f3f4  36... e6e5 Creates a passer at once while opening the f-file for his rook and the e6-square for the king. 37. f4e5  37... f6e5  38. d2e2  38... c8f8  39. f2e1  39... f8f5  40. b6b1  40... e5e4  41. b1c1  41... e7h4  42. g2g3  42... h4g5  43. c1b1  43... f5f3 The black pieces steadily put the situation under control. 44. a3c1  44... g5f6  45. b1b6  45... f3f5  46. c1a3
