{ The breakthrough systematically prepared  The difference between this
partially fixed formation and the normal blocked oblique centre is that the
Black d-pawn stands on d7 instead of d5, and this improves Black's chances as
d5 is a splendid support-point for his Knight. For the time being White
retains some chances of Kingside attack, and his two Bishops may play a useful
part; but sooner or later the tide must turn. Black's strategy includes the
opening of the f-file by ... Pf6 } 1... Rac8 ( 1... f6 2. Qh4 Rf7 3. Bxg6 ) 2. Bd1 ( 2. Qh4 Nf6 3. Be4 Qxc1+ 4. Rxc1 Rxc1+ 5. Kf2 Nxe4+ 6. Ke3 h5 ) 2... f6 3.
