Nf3 e6 7. Be2 exd5 8. cxd5 d6 {As an experienced Benoni player, I have
problems finding a proper name for this almost non-existent variation; "the
e3-Benoni" sounds almost comical! However, White's setup is not without venom.
By refraining from exposing his e-pawn to early attacks (...Re8), White
intends to obtain more freedom of action for his minor pieces. His king's
knight could go to c2 (via e1) in order to counter a later ...b5 with b4, or
to the more usual c4-square, without having to care about defending the
e4-pawn from d2. We shall see further differences with respect to the
classical system (e4, Nf3 and Be2) as the game advances. White's philosophy is
similar to that from the fianchetto system: White refrains from an early
occupation of the centre, but the later advance of the e-pawn should not be
discarded. One possible drawback of this system is that the c1-bishop will
remain passive for a long time. From psychological point of view, Morozevich's
choice is simply brilliant. Kramnik does not play this opening regularly 
(although he employed it in the penultimate game of his match against Leko,
when he desperately needed to win) and, almost surely, never studied the
e3-system! There are not many recent cases when the World Champion was taken
"out of the book" at such an early stage, with the position remaining complex
at the same time. Como jugador con mucha experiencнa de Benoni, tengo
problemas en encontrar un nombre a esta casi inexistente variante; "la Benoni
con e3" Ўsueсa casi cуmico! Sin embargo, el sistema de desarrollo escogido por
las blancas no carece de veneno. Al evitar de exponer su peуn de e a ataques
tempranos (...Re8), las blancas aseguran mayor movilidad a sus figuras menores.
Por ejemplo, el caballo de rey puede ser trasladado a c2, para contestar un
eventual ...b5 con b4, o a c4, sin necesidad de defender el peуn de e4 desde
d2. Veremos mбs detalles a lo largo de la partida. Una posible desventaja
serнa conectada con las dificultades en desarrollar el alfil de c1. Desde un
punto de vista psicolуgico, la escogida de variante de Morozevich es
simplemente brillante. Kramnik casi no juega la Benoni (aunque si la empleу en
la penъltima partida de su encuentro contra Leko, cuando necesitaba
desesperadamente ganar) y, ciertamente, Ўnunca debio de estudiar la variante
de e3! Noson muchos los casos recientes cuando el Campeуn del Mundo fue sacado
de su libro de aperturas en un estado tan temprano de la partida, con la
posiciуn quedando suficientemente complicada.} 9. O-O Bg4 {Since Black is

able to face up to the young contenders. But despite his poor over-all
performance he did play two very attractive games with rook sacrifices. Im
historischen Kandidatenturnier in Zьrich 1953 war der alternde Euwe nicht mehr

little to complain that the pawn moved from c3 to c5 - on c5 it only helps
Black to exchange it by means of b7-b6 and also open more files.} 21. Rab1 b6
