The not often played 'Jaenisch Variation' of the 'Ruy Lopez', probably prepared by Radjabov before-hand especially for this event.

4.d3
[4.Nc3
is considered to be the main line but things are not so clear-cut anyway and I am pretty sure that Radjabov would have come up with some fresh ideas.]

White has gained a clear and long-term advantage. The material in quantity terms is equal but just compare the white e- and f-pawns to the black c5- and c6-pawns. Then it is easy to understand that quality counts.
