White has numerous ways to secure an advantage. 11 Qd2, to recapture with the queen on f4, looks attractive, and so does 11 Be3, but none of them can compare to the way Karpov decides to alter the pawn structure!
11.e3!
Maintaining perfect control over the center. As far as ideal squares are concerned, here it is the disappearance of them. Now Black is unable to find any good squares for his pieces.
11...Nxf4 12.exf4
Now Black has no easy way to develop. In fact examination of the position indicates that there is no difficult way either!
