1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... h7h6 Dubov's pet move with which he  won a few beautiful games last year (see below). 5. b1c3  5... f8b4  6. e1g1  6... b4c3  7. b2c3  7... e8g8  8. c4b3 Not a common continuation  but a logical move. The bishop steps back in anticipation of the imminent  central break d7-d5. 8... d7d5  9. e4d5  9... f6d5  10. h2h3 This pawn sacrifice turns out to be  dubious, to say the least. 10... d5c3 Dubov accepts the sacrifice and quickly spots an  important attacking detail. 11. d1e1  11... c6d4 The point. 12. f3e5  12... c3e2  13. g1h1 This move, played almost instantly, is a blunder!  Carlsen wanted to avoid problems along the b8-h2 diagonal, but it turns  out that the king is not safe there either. 13... c8h3 Uncovering the king along the long diagonal. 14. g2h3  14... d4b3  15. e1e2  15... d8d5 This intermediate check might have been  missed by the world champion. 16. h1h2  16... b3a1 Ah, such a pity! Dubov missed a brilliant way to finish the  game in his favor. 17. c1b2 Now White gets a glimpse of hope. 17... a8e8 And after this  obvious move, there might not be a win at all! 18. f1g1 The four remaining white pieces develop a strong initiative  against the enemy king on the open files and diagonals. 18... f7f6  19. e2g4  19... g7g5 As risky as it looks, Dubov had no other choice. 20. g4f5  20... e8e7 Reluctant to accept the draw, the Russian GM even loses now! 21. e5g6  21... d5d6  22. g1g3  22... a1c2  23. g6f8 Carlsen wins a piece and quickly  finishes the game. 23... c2d4  24. b2d4  24... d6d4  25. f8e6  25... d4e5  26. f5g6  26... g8h8  27. g6h6  27... h8g8
