Not every game is a tactical melee. Today GM Khachiyan admits that he did "nothing special" - but there is beauty in simplicity. He's the king of practical play, and he chooses the most solid moves at every turn, stifling his opponent. Don't let Melik grab hold of an open file or let him latch on to a weak pawn. You'll be given a lesson in Karpovian style, but it'll cost you the point.
