1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... g8f6  4. d2d3 Not yet an endgame with you, Mr  Carlsen. 4... f8c5  5. b5c6  5... d7c6  6. e1g1  6... c8g4 The most annoying reply for the first player. Once that he  castled, he needs to think twice if he really wants to break the pin with  the g2-g4 move. 7. h2h3  7... g4h5  8. b1d2  8... f6d7  9. d2c4  9... f7f6  10. a1b1 A  novelty which intends to dispatch the black bishop from the a7-g1  diagonal. 10... a7a5 Carlsen wants his bishop on the diagonal. 11. c1d2  11... b7b6  12. d2e3  12... c5e7 Now that the e3 square is occupied by the white  bishop, Black can retreat. 13. b2b3 White is arranging his pawns according to Capablanca's rule: on  the opposite color of his own bishop. Make no mistake though, this is  purely defensive here as they are not moving anywhere. 13... d7c5 Carlsen wants to occupy the d4 square in the most convenient  way. 14. a2a4  14... c5e6  15. d1e2  15... c6c5  16. c2c3 Firouzja needs to change the trend. If he stays, he will be slowly smothered. 16... d8d7  17. f1d1  17... a8d8  18. b1b2  18... d7c8  19. b2d2 White is consistent with the preparation of the  d3-d4 break. Indeed, there is nothing else that he can play for. 19... e8g8  20. g2g4  20... h5f7  21. f3h4  21... g7g6  22. h4g2  22... g6g5 Carlsen is stopping the other typical break for  White, f2-f4. 23. f2f3  23... h7h5  24. e3f2  24... g8h7 In order to occupy the h-file before opening it. 25. c4e3 Active play. 25... f8h8  26. e3f5  26... e7f8 Now that the black pieces are awkwardly placed,  the moment should be right: 27. d3d4 Changing the rhythm of the game when  even world champions may err. 27... c5d4  28. c3d4
