[%c_effect h2;square;h2;type;Blunder;persistent;true] A rare blunder by Carlsen.
1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5  3... e7e6  4. b5c6  4... b7c6  5. b2b3  5... d7d6  6. e4e5  6... d6e5  7. d2d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] Carlsen strikes with a prepared novelty. Previously White captured automatically on e5. The move played in the game is a new plan, but it's also the computer's first choice, so probably Abasov knew about it. 7... f7f6  8. b1d2 White has long-term compensation for the sacrificed pawn. The c5-pawn is weak and will hardly escape a capture, while Black's structure makes his main asset, the bishop pair, not so useful at the moment. 8... g8h6  9. h1g1 [%c_effect g1;square;g1;type;GreatFind;persistent;true] An extraordinary plan that is certainly part of Carlsen's home preparation. White intends to advance the kingside and castle on the queenside. 9... c8a6 [%c_effect a6;square;a6;type;Inaccuracy;persistent;true] The computer considers this move an inaccuracy. I believe that Abasov had his eye on the typical c5-c4 advance, returning the pawn to open the game. 10. g2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 10... h6f7 Here and on the next moves Carlsen had the option of playing g4-g5, gaining space on the kingside before finishing development. 11. d1e2  11... f8e7  12. c1b2  12... d8a5  13. c2c4 This is a small inaccuracy. Maybe Carlsen wanted to avoid c5-c4 once and for all. 13... g7g5 [%c_effect g5;square;g5;type;Interesting;persistent;true] An interesting move, avoiding g4-g5. 14. h2h4  14... h7h6  15. g1h1  15... e8c8  16. e1c1  16... a5c7  17. d2e4  17... g5h4 [%c_effect h4;square;h4;type;Interesting;persistent;true] An excellent practical choice. It's necessary to change the trend of the game and look for active chances. 18. f3h4  18... h8g8  19. f2f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Carlsen said in the interview that he didn't see a good alternative to this move. First he wanted to play slowly with 19.f3, but Black can play 19...Kb8 with the idea of ...Bc8 and then f6-f5. 19... e5f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] Otherwise White can play f4-f5 with the advantage. 20. e4f6  20... e7f6  21. e2e6  21... c8b8  22. e6f6  22... a6c8  23. d1e1  23... d8d6  24. f6f4  24... g8g4  25. f4e3 It's not clear if this is the best square for the queen. White keeps some pressure after 25.Qf2 and 25.Qd2. 25... d6e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] 26. e3d2  26... f7e5  27. c1c2  27... b8b7  28. e1e3  28... c7e7 [%c_effect e7;square;e7;type;GreatFind;persistent;true] 29. h4f5  29... e7g5  30. b2e5  30... g4g2  31. e3e2  31... g2e2  32. d2e2  32... g5f5  33. h1h5  33... f5f7
