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.
