1. c2c4  1... g8f6  2. g1f3  2... e7e6  3. b1c3  3... d7d5  4. e2e3  4... c7c5  5. d2d4  5... a7a6  6. c4d5  6... e6d5  7. g2g3 [%c_effect g3;square;g3;type;Inaccuracy;persistent;true] In the post-game interview, Carlsen said that he doesn't understand why players keep choosing this line, as he thinks it's very comfortable for Black to play. In light of these words, I guess I have to label 7.g3 as a dubious move. It's hard to argue against Carlsen's chess understanding. 7... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] Carlsen has experience with this move. He has won all the games he has played in this position. 8. f1g2  8... f8b4 This is a great square for the bishop. This piece is ready to capture the knight on c3, if necessary, followed by a knight jump to e4. 9. e1g1  9... e8g8  10. f3e5  10... f8e8  11. c1d2  11... b8c6  12. a2a3 A new move. 12... b4a5 There's no need to hurry to capture the knight. 13. b2b4  13... c4b3  14. e5c6  14... b7c6  15. d1b3  15... h7h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] This is Black's typical plan on this pawn structure. 16. b3c2  16... h5h4  17. f1c1  17... h4h3 [%c_effect h3;square;h3;type;GreatFind;persistent;true] If there's something we've learned from AlphaZero, it is that this h-pawn can just keep going. Before that, grandmasters usually preferred, in similar positions, to keep the tension or even capture on g3 and then try to mate on the h-file. 18. g2h1  18... c8g4  19. c3b1 [%c_effect b1;square;b1;type;Inaccuracy;persistent;true] An ugly move, but So wanted to capture on d2 with the knight. 19... a5b6 [%c_effect b6;square;b6;type;GreatFind;persistent;true] Very accurate play by Carlsen. 20. d2b4 Trying to place the knight on d2. 20... f6e4  21. h1e4  21... e8e4  22. b1d2  22... e4e6 The light squares will be a constant headache for White. The computer already evaluates the position as winning for Black. 23. c2d3  23... d8f6  24. d3f1 The queen returns to make the f2-f3 push possible. 24... e6e8 This is a really difficult move to play. I'd have a hard time removing the rook from e6 and sending it to the queenside. 25. a1b1  25... e8b8  26. b4c5  26... b6a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] 27. c5b4  27... a5c7  28. b4c3  28... a6a5  29. f2f3  29... g4f5  30. e3e4  30... f5e6  31. e4e5 [%c_effect e5;square;e5;type;Inaccuracy;persistent;true] 31... f6e7 The a3-pawn is under fire. 32. b1a1  32... c6c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] The final breakthrough. 33. f1f2
