$1 {Diagram [#] Attacking Black's outpost with the c-pawn is superior to 8.e3
or 8.e4 which was dealt with in the last game. As you will see soon, it is
best to do so immediately, since a preparation isn't necessary. Nonetheless,
in most games White did exactly this and played 8.Bd2. If there is any line in
the whole 6..d4-complex, which is capable to exert a certain pressure on Black,
than it is 8.c3! Very logically a man of Karjakin's strength is opting for
exactly this.} (8. Bd2 {Now, Black has easy equality:} e5 (8... Nd5 {is a good
