First White brings all his pieces into better
positions for a siege:

This gives White a potential pawn-break to
open a second front. 5 ... @f6 was indicated.

If the doubled pawn is part of a compact
pawn-mass, things are generally not so simple,
since they often provide support-points for
pieces; the pawns themselves have great resilience
and do not constitute a static weakness.
However, only rarely do they exhibit any dynamism.

Important prophylaxis, since the immediate 9
cd? could be answered by 9 ... c5 ! IO bxc6 tZ)xc6.
The black structure is still compact, but he
must watch out for White eventually playing
b5.
