1. e2e4  1... e7e6 The French Defense is rarely played by Carlsen in classical games, although he had beaten Karjakin and Ivanchuk with it a long time ago. 2. d2d4  2... d7d5  3. b1c3  3... g8f6  4. e4e5  4... f6d7  5. f2f4  5... c7c5  6. g1f3  6... b8c6  7. c1e3  7... a7a6  8. c3e2 Caruana has played this before in a blitz game, so it hardly came as a surprise. It's also the first move of the engine I used. 8... d8b6  9. d1c1  9... f8e7  10. c2c3  10... e8g8  11. g2g3  11... f7f6  12. f1g2  12... c5d4  13. c3d4  13... b6a5  14. e2c3 [%c_effect c3;square;c3;type;GreatFind;persistent;true] A new move. 14... d7b6 Carlsen prepares the development of the light-squared bishop. 15. e5f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] A capture that changes the pawn structure is always a difficult one to choose. 15... e7f6  16. b2b3 Now this move is possible. 16... c8d7  17. e1g1  17... a8c8  18. c1d2  18... f6e7  19. c3e2  19... a5d2  20. e3d2 White has a slightly better endgame. The backward e-pawn is always a concern for Black, but the position is not the end of the world. 20... c8c7 The plan is to double rooks on the c-file. 21. a1c1  21... f8c8  22. f4f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] A very good move, seizing a tactical chance. The pawn cannot be captured because the c7-rook has no squares. 22... e7a3  23. c1e1  23... a3b4  24. d2b4  24... c6b4  25. f5e6  25... d7e6  26. e2f4  26... e6f5  27. f3e5 A good and natural human move. 27... g7g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] Very good defense by Carlsen. The bishop is protected. 28. g3g4  28... f5e4
