The Russian GM brings out his light-squared bishop at the price of a pawn and forces his opponent into defense. 15. a3b4  15... c8b7  16. b1d2  16... a7a5  17. a1a5  17... a8a5  18. b4a5  18... d8a5  19. f3d4  19... h6f5 At the end of the  day, Dubov sacrificed a pawn. In return he has brought back his knight  into the game and developed his remaining pieces aggressively. Carlsen has to watch out.
