That said, it's possible to delay this capture as well. 16. f2e3  16... e8g8  17. e1g1  17... b8a8 [%c_effect a8;square;a8;type;Inaccuracy;persistent;true] 18. a1a8  18... f8a8  19. f3h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] A strong move, using tactics to bring the knight to f5. 19... e6g4  20. d1e1  20... c6a5 [%c_effect a5;square;a5;type;Inaccuracy;persistent;true] 21. b3d1  21... g4d1 The f5-square becomes very weak now. Maybe it's better to retreat the bishop, although after 22. h4f5  22... e7e6  23. e1d1  23... g8h7  24. h2h4 [%c_effect h4;square;h4;type;Inaccuracy;persistent;true] This is Carlsen's only inaccuracy in the game. 24... a8g8 [%c_effect g8;square;g8;type;Inaccuracy;persistent;true] Tabatabaei misses the chance to come back to the game. 25. h4g5  25... g8g5  26. g3h4  26... g5g6  27. b2b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 27... a5c6  28. d1f3  28... f6g8  29. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] Carlsen conducts the game with his typical precision. Black has too many weaknesses, and his pieces are passive. 29... e5d4  30. e3d4
