The knight finds a good square on b5. 10... b8c6  11. a3b5  11... d6b8 Keeping the bishop is important because it protects the center. Eventually, Black can develop the rook on a6. 12. d1e2 An ambitious idea that Rapport has already tried in a blitz game. White prepares to castle queenside. 12... e8g8  13. e1c1  13... f8e8  14. h1e1  14... h7h6  15. g5h4 The moves from both sides are the most natural after 13.Qe2. One question I have here is whether Black can play g7-g5 to get out of the pin. This is always a difficult move to evaluate in this type of position, leaving us to wonder whether it's worth weakening the kingside and if White can sac the knight on g5. 15... d5d4  16. e2c2 A new and strong move. 16... e6b3  17. c2b3  17... b8a7  18. c1b1 When in doubt, play Kb1 after castling queenside. You can never be too wrong when playing that move. 18... d4c3  19. b2c3  19... a7b6 A calm move, improving the bishop's position. Definitely not an easy move to play, 20. f3d2 Carlsen sacrifices the d3-pawn with check $1 One way to set this up would be to get the king to b2 first. 20... b6c5 Moving the bishop again is too much. 21. h4f6  21... d8f6  22. b5c7  22... f6g6  23. d2e4 Normally, one would expect an easy and comfortable victory for Carlsen in such a position. In this case, however, the players embark on a few adventures. 23... c5e7  24. e1e3  24... g8h8  25. c7a8  25... e8a8  26. e3g3  26... g6h5  27. g3f3  27... a8f8  28. e4g3  28... h5g6  29. g3f5 This allows some counterplay. 29... e7g5  30. g2g4  30... g5f4  31. h2h3  31... f8b8  32. b1c2  32... c6a7  33. b3d5  33... f7f6  34. d1b1 It looks like the game is over, and Black can just resign.
