12) Total Sealing of the Position
This method is seldom feasible, but if the position
is already very closed and only a few
pawn-breaks are available, it can sometimes
be applied.
In the following position, if Black manages
to seal off the queenside, White will be unable
to make progress.
1...it.b7?!
l...a5 was correct. This theme also persists
in the following moves; for example, 2 h4 (2 a3
tZ:lb8 3 b4 axb4 4 axb4 li:la6 5 bxc5 tZ:lxc5 =)
2 ... li:lb8 3 @g3 li:la6 4 h5 it.d7 5 h6 tZ:lb4 6 it.bl
@e8 = (Hazai in CBM).

2 h4 Sl.c8 3 h5 it.b7 4 a3 it.c8?!
Now 4 ... a5! was an urgent necessity.
5h6?!
5 b4 was indicated, to prevent the sealing of
the queenside with ... a5.

Finally White seizes his chance. Now Black
must be extremely careful
