1. e2e4  1... c7c5  2. d2d4  2... c5d4  3. d1d4 A Center Game against the Sicilian $2 Not a common one $1 3... b8c6  4. d4d3  4... g7g6 After a tempo gain, Carlsen decided to opt for a Dragon setup. This is one of the many ways to achieve a good position out of the opening. 5. b1c3  5... f8g7  6. g1f3  6... g8f6  7. f1e2  7... e8g8  8. e1g1  8... d7d6  9. c3d5 The only way to justify the early sortie of the white queen. If the knights are traded, White would enjoy a nice space advantage and easy play along the half-open e-file. However 9... f6d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] spoiled White's plans, and Black is doing great out of the opening after 10. c2c3  10... d7c5  11. d3c2  11... e7e6  12. d5e3 White's pieces look ugly, but as we shall witness Shimanov knows how to bring them together. 12... d8c7  13. f1d1  13... f8d8  14. b2b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] This is the point: the white bishop would feel great on the long diagonal. 14... c5d7  15. a2a3  15... d7e5  16. c1b2  16... e5f3  17. e2f3  17... a7a5 Carlsen adds additional pressure on the b4-pawn, thus, trying to keep the long diagonal closed for the time being. 18. a1c1  18... c8d7  19. c3c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] But a little tactic solves the minor queenside issues that White has experienced. 19... a5b4  20. b2g7  20... g8g7  21. a3b4  21... e6e5 A common idea after the bishop swap, but here it was a tad premature. 22. e3d5  22... c7b8  23. c2b2 Shimanov is heading to the correct idea but drops a tempo in the process. 23... d7e6  24. h2h4 White's chances are connected with the kingside. 24... h7h5  25. b4b5 Same idea, but... 25... e6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] Not the same result now. 26. c4d5 Another inaccuracy. As we shall see, the open c-file plays well for Black. 26... c6d4  27. d1d4 This knight cannot be left onboard. 27... e5d4  28. b2d4  28... g7g8 Black's position seems scary, but as it often happens, Carlsen's pieces arrive in time. 29. g2g4  29... d8c8 [%c_effect c8;square;c8;type;GreatFind;persistent;true] All Black needs is to get rid of the major pieces. 30. c1e1  30... h5g4  31. f3g4  31... c8c2  32. h4h5 Now Black needs to decide how to cover the dark squares. 32... b8a7 Carlsen errs. 33. d4f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] 33... a7a5  34. e1f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] Remember this rook; his time has not come yet. 34... a5d8 [%c_effect d8;square;d8;type;GreatFind;persistent;true] Back to the right place. 35. f6f4  35... d8e7  36. h5g6  36... f7g6  37. f4h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] This is the difference $1 The white queen gets within a striking distance of the enemy king. 37... e7g7  38. g4e6  38... g8f8  39. h6g5  39... c2c4  40. g1g2 [%c_effect g2;square;g2;type;Brilliant;persistent;true] Shimanov plays for the win $1 White's last piece joins the attack, and the time scramble as always benefits the attacker.
