When entering the Exchange Variation of the Queen's Gambit, White should always take care to control of the b1-b7 diagonal, and his move-order is conditioned by that ambition. The queen move haa several positive points, an early simplifying ...ke4 is prevented, ...Bf5 is thwarted, and White's dominance of this diagonal will facilitate either a kingside attack or a queenside minority attack, depending on where White castles.
7...Nbd7
8.Nf3
Nf8
The beginning of a long maneuver which will take the knight via e6 and g7 to f5. At this delicate4 opening stage, it is dubious to invest so much time in a somewhat unnatural scheme. Some times this elaborate plan involves a different route - a6-c7-e6-g7-f5. In contrast the simple, logical 8...0-0 looks healthier.

Both sides consistently carry out their strategic plans. Black prepares 13...Bf5 and desires simplifications, while White is ready to play b4. 12...a5 13.a3 would not change the course of events.
13.b4
The closed pawn-center as a rule directs the play towards the wings. By advancing his b-pawn, White follows an old prescription, to reach the b5 square and exchange at c6, creating a backward pawn on the c-file, the potential target of his pressure.

We see the MINORITY ATTACK in its pure form. As a result, White's more compact pawn-structure will be an asset , but for the time being the inevitable reduction of material helps Black to keep his problems under control.
