7...Be5 8.Bxg7! Bxg3 9.Rxg3 with mate to come.

With a decisive advantage.

Heading for a7 in order to seize the g1-a7 diagonal, where there is no opposing white bishop.

Or 4.cxd5 Ne5 5.Qd2 f5! with counterplay

Black is completely winning.

Preparing 2...Rh8 to fight for the h-file.

3.Rxh8 Qxh8 and the queen takes command of both the h-file and the a1-h8 diagonal.

Now Black enjoys a pleasant initiative.

With the centre safely blocked, this is the simplest way of securing the king and connecting the major pieces.
