FORTRESSES 101

Black has a simple drawing plan: he puts his
king on c7, after which the queenside is safe
against any infiltration by the white king, and
then he simply oscillates his bishop between d6
and e7. Black's fortress cannot be breached by
a bishop sacrifice at h6 either: if the white king
stays on the queenside, then .i.h6 will always
be answered by ... i.f8, with the threat of ... gxh6.
If White prepares the .i.h6 sacrifice by @h5,
Black need not take on h6 (since then g7 follows),
but can simply wait with a king move.

A peculiar kind of drawn position has arisen.
The great defensive power of Black's bishop
stands in stark contrast to its minimal attacking
potential.
The pawn-barrier is also an important defensive
idea in pawn endings themselves. Take a
look at what happened in the following game:

In both preceding examples, the pawn-chains
of future barriers were easy to foresee. In this
position, however, the contours of a possible
pawn-barrier are somewhat obscured. But with
the right idea, this position too is easy to defend.

White has an extra protected passed pawn
and obviously should be clearly winning. Black
is unable to keep the kingside closed and with
precise play White will penetrate there in a few
moves.

This move does not spoil anything. How-
ever, 2 g4! is technically more convincing.

unaware of any danger. 3 'i9f2 would
