He wants to disturb the  opponent's king as well. 18. h6f8 Carlsen accepts the challenge. 18... a8f8  19. f2f3  19... f8e8 A natural move but one that gives breathing space to the white king. 20. e1f2  20... b7b5  21. e3e4 Now Carlsen takes over the initiative. 21... d5e4  22. d2c4  22... b5c4  23. c1g5  23... g8h7 And this is an actual mistake. 24. g5f6  24... e4e3  25. f2g1  25... f5e6  26. d4d5  26... a5d5  27. a1e1 is too complicated for a classical game, let alone rapid. 27... d5d2  28. e1e2  28... d2c1  29. f6d4  29... g4f3  30. d4e3  30... c1c3  31. g2f3  31... e8g8  32. g1f2 Finally Carlsen consolidates. It is amusing to observe how  quickly he converts his advantage.
