1. d4 d5 2. Nb3 e5 3. dxe5 Rxe5 4. Bf4 Re8 5. Nc3 Bb4 6. Bd2. 6. e4 Bxc3 7. bxc3 dxe4 8. Bb5 Nc6 9. a4 is another (interesting) way to make a gambit of it . 6. ... Nb6 7. e4. Carlsen goes for a Pawn sacrifice. 7. ... Bxc3 8. Bxc3 dxe4 9. Qd1. Threatening Re1xe4. 9. ... f5 10. Qd4 Ne6 11. Qe5 0-0 12. Nc5 Re7 13. Rd1 Rff7. Nakamura defended the seventh rank to such an extent to weaken the eight rank! 14. Be2. Intending Be2-h5. 14. a4 (Δ a4-a5) would be equally answered by 14. ... Nf8. 14. ... Nf8 15. Qf4 Ng6 16. Qg3. Best seems 16. Qg5 (Δ Be2-h5) 16. ... c6(!) 17. Bh5 Nd5 18. Bxg6 hxg6 and after 19. h4 (threatening Rd1xd5 followed by h4-h5) 19. ... Qd6(!) 20. h5 gxh5 21. Qxh5 Qh6 Black manages to give back the Pawn just in time for avoiding the worst outcome. 16. ... f4. On the other hand, Nakamura, too, seems to miss the “difficult to see” 16. ... Re8! (Stockfish) which threatens to trap the Queen by 17. ... f4 18. Qg5 Rf5. 17. Rd8+ Rf8 18. Rxf8+ Kxf8 19. Qg5 c6 20. h4! Threatening h4-h5-(h6).
20. ... f3! Black temporarily returns the Pawn to seize the initiative. 21. gxf3 Nf4 22. Bf1 exf3 23. Nd3! Nxd3 24. Bxd3 h6 25. Qg3 Qxg3+ 26. fxg3 Na4 27. Bd2? Despite his minus Pawn White should have been able to get a draw by 27. Bb4 c5 28. Ba3 (Δ b2-b3) 28. ... b6!? 29. Kf2 Bb7!? 30. c3 (not 30. Bb5? on account of 30. ... a6! 31. Bxa4 Re2+ 32. Kf1 Rd2! with powerful threats) 30. ... a6 with a dynamic balance. 27. ... Kg8 28. b3? 28. Bb4 Re5∓ seems to be a lesser evil. 28. ... Nb2 29. Bg6 Nd1! Threatening ... Re7-e2. 30. 0-0. White finally performs his “Rook-move-only” castling, but a little too late for His Majesty to enjoy. 30. ... Bg4 31. Bd3 f2+ 32. Kg2 b5 33. a4 a6 34. axb5 axb5 35. Bb4 Re5 36. Bd2 Re8 37. Bf4 b4 38. Bd2 c5 39. Bf4 Kf7 40. Bd6. Since White cannot prevent the Black King from making decisive progress (such as going to f6 in order to support the advance ... g7-g5), he decides to try his luck with a desperate and totally vain Exchange sacrifice. “I did not know how many moves I had made so far, so I made an impulsive decision”, Carlsen told NRK afterwards. “Had I known that it was the 40th move already, I would have at least delayed such a decision a little longer. However, I guess I couldn’t have saved myself anyway. The position was too bad”. 40. ... Ne3+ 41. Kxf2 Nxf1 42. Bxf1 Rc8 43. Be5 Bf5 44. Bc4+ Kg6 45. Ke3 Bxc2 46. g4 Re8 47. Kf4 Rf8+ 48. Ke3 Re8 49. Kf4 Rd8 50. h5+ Kh7 51. Ke3 Bd1 52. Bd3+ Kh8 0 : 1.
