1. c2c4  1... e7e5  2. b1c3  2... g8f6  3. g2g3  3... f8b4 A curious thematic match. The Rossolimo  line was discussed disregarding the color. 4. e2e4  4... b4c3  5. b2c3  5... e8g8  6. f2f3 Amazing how fresh these positions are. This is a  novelty! 6... b7b5 And a bold sacrifice in return! 7. d2d4 Long-term factors before everything. Notice how again Carlsen has  only pawns moving, but the presence of his bishop pair makes the dynamic  risk worth it. 7... e5d4  8. c3d4  8... b5c4  9. e4e5 An important move to win a couple of tempos for the  development and stabilize the center. 9... f6d5  10. f1c4  10... c8b7  11. g1h3 The best square for the knight. 11... d7d6  12. e1g1 Now Carlsen misses a chance to use the bishops effectively. 12... b8d7  13. f1e1  13... d6e5  14. d4e5  14... d7b6  15. c4b3 So far both players have played brave, uncompromising chess, and this led to an extremely messy position. 15... d8e7 But this move turns out to be a nasty blunder. 16. e5e6 Carlsen needs no second invitation. 16... f7e6 Caruana  follows his plan, but he might have missed a detail. 17. h3g5  17... f8f6  18. d1c2  18... f6g6 It seems the American GM missed White's next  power blow. 19. e1e6 A killer. 19... e7e6  20. g5e6  20... g6e6  21. c1b2 Carlsen wins material and keeps his best pieces  aboard. The rest is easy for the world champion: 21... a8e8  22. b2d4  22... g8h8  23. c2f5  23... b7c8  24. f5h5  24... c7c5  25. d4c5  25... e6e5  26. h5f7  26... c8h3  27. c5f8  27... e5e1  28. a1e1
