1. g1f3  1... g8f6  2. g2g3  2... d7d5  3. f1g2  3... e7e6  4. e1g1  4... f8e7  5. c2c4 After a short flirt with the open games against Carlsen, Artemiev returns to his bread and butter—the Reti. 5... d5d4  6. e2e3  6... c7c5  7. e3d4  7... c5d4  8. f3e5 It is a reversed Benoni and besides the first move advantage White has one more hidden tempo—the black e-pawn only moved to the sixth rank. Thus, why not play more actively? 8... d8c7 Mamedyarov tries to fight the annoying knight at once and does it with a novelty. 9. f1e1  9... e7d6  10. d1e2  10... b8d7 This is where things really started to go downhill for the Azerbaijani GM. 11. e5f3 Justified both tactically and positonally. The black pieces are stepping on each others' toes, therefore Artemiev does not plan to free them with trades. 11... c7b6  12. b1a3 The d4 pawn is in huge danger, and the white pieces are entering the battle with clear aims. 12... d6c5  13. d2d3 Once more White is tactically alert. 13... e8g8  14. c1f4 Practically paralyzing his opponent with natural moves. 14... a7a6  15. a1b1  15... c5b4  16. f4d2 Lifting the blockade. 16... e6e5 In his younger days Mamedyarov played countless games with his friend and Benoni expert Vugar Gashimov. He certainly knows what kind of a mess he is into, and tries to escape tactically. 17. d2b4 Very consistent play again.
