Probably the most significant development of recent years has been establishing that nowadays after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Be7 in addition to 5.Bg5 there is a second main move in 5.Bf4. And after 5.Bf4 0-0 6.e3 there is a trend towards 6...c5, with above all the name of Hikaru Nakamura being attached to it. The American has especially after 7.dxc5 Bxc5 8.a3 Nc6 9.Qc2 Qa5
10.Rd1 given impetus to the renaissance of 10...Re8. In the position in the diagram the Powerbook offers branches with in each case numbers in the mid four figures. But although after 10.Rd1, 10.0-0-0 and 10.Nd2 White can demonstrate a slight plus in each case, Black’s position appears to be basically solid.
