1. e2e4  1... e7e5  2. g1f3  2... g8f6 The Petroff defense is an important part of  Mamedyarov's opening repertoire. Still, it feels somewhat unusual. 3. f3e5  3... d7d6  4. e5f3  4... f6e4  5. d2d4  5... d6d5  6. f1d3  6... f8d6  7. e1g1  7... e8g8  8. c2c4  8... c7c6  9. d1b3  9... d5c4 Quite a fresh try. 10. d3c4 [#] 10... b7b5 Fighting for the control over the d5  square with a novelty. 11. c4d3  11... e4f6  12. f1e1 Dominguez is looking for a way to occupy the  e5-square as early as he can. 12... b8a6  13. a2a3 This knight definitely cannot be allowed on b4. 13... c8g4 Very natural play by Mamedyarov. He increases his lead in  development. 14. d3c2 Dominguez continues with his aggressive strategy. 14... f8e8  15. f3e5  15... d8c7  16. b3g3 Still this risky play! Why not develop the queenside. 16... c6c5 Of course! With the fall of the d4-pawn the White's position  is on the verge of the collapse. Dominguez believes that he has it all  covered and enters a forcing line. 17. c1g5  17... c5d4  18. g5f6
