The point is that after a later f5 by Black, the manouvre exf5 gxf5 and then g5 will keep the black minor pieces caged in. The h-file is also opened for attack.

There is a aping hole on c6. We now get an example of the classical principle of two weaknesses. White can probe Black on both the K and Q-side. This double stress will in the end be to much for the defenders, since they lack coordination and space. 29... Ja6 30.
