THE ART OF PAWN PLAY

A further example of the legendary strength
of a blockading knight:
B
2.11
I.Bondarevsky- V.Smyslov
Moscow Ch 1946
White cannot really profit from his lead in
development, since he cannot open the position
in his favour. In fact, he should already be
thinking about damage limitation, since Black
has the following idea at his disposal:
1 ... fS! '
The aim is to set up a light-squared blockade.
2 eS?
A serious positional mistake which deprives
White of any counterplay. 2 it.gs! ~xgS 3 lbxgS
h6 (Wells in CBM) was more accurate, even if
Black's position is still slightly preferable.
2 ... lbe6 3 it.d2 gS 4 lbe2 cS!
It is very important that White cannot exchange
the e6-knight.

Thanks to the mighty blockading knight,
within a very short time Smyslov has completely
outplayed his opponent.

The presence of opposite-coloured bishops
is here no indication of drawing chances; instead
it merely accentuates Black's advantage.

The rook is not a good blockader since, in
contrast to the knight, it exerts no active power
from its blockading square. Furthermore it can
easily be dislodged by pieces of lesser value.
2.12
H.Kmoch - A.Nimzowitsch
Bad Niendorf 1927
Nimzowitsch disrupts the white blockade
with a fantastic move, which gives him three
connected passed pawns:
1 ... 1;!.b4!! 2 cxb4 a4 3 bS+ @xbS 4 .i.a3 c3 S
1:lbl @c4 6 f4 @xd4 7 @£2 @c4 8 @el d4 9

In the next example Black succeeds in breaking
the blockade:
