Karjakin, Sergey (2760) - Kramnik, Vladimir (2790)
Moscow Tal Memorial 5th (Moscow), 11/13/2010

Round 8 [Stohl,I]


1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nf3 Nxe4 5.Nc3 Nxc3 6.dxc3 One of the attractions of this line is it often leads to a complex struggle with opposite-side castling and in that case White's king is well protected on the << by the doubled c-pawns. However, this doesn't mean that White gets a strong -> automatically: the open <-> e is a strong neutralizing factor and he must reckon with Black's [+]<=> as well.
6...Be7



7.Be3 /\Qd2,0-0-0
[The other main move with similar ideas is
7.Bf4 , but this is recently somewhat less fashionable among the top players (although in general it's played rather more often, than the text-move). Now Black has a choice:
