to black's defence, and control of it
MUST be recovered. The 'loss' of white's
dark squared bishop gives black a handy
superiority on these squares, and again,
as mentioned in the text, white's heavy
commitment to the attack ( note the poor
co-ordination between his king-side
major pieces and the rook on a4 ) is a
further source of justification and
compensation.

Again, it is at least partly the degree of
white's commitment to attack,and the
concomitant structural neglect of the
queenside ( don't overlook black's
glorious knight on c5 ) which helps to
justify this. Also do not underestimate
the importance of the role of the queen
on e7 in denying white's queen access to
h4.

It is also worth mentioning the effect of
the sacrifice on the value of the c2
bishop. In the attacking notes above, this
piece had a truly heroic role to play. It
can in this sense be seen as part of the
'commitment to all-out attack baggage' of
white's position. Without these threats, it
resembles a depressingly standard 'bad'
bishop. What of my discussion of these
ambiguities in CBM77? Well, I have to
admit that it performs a reasonable duty
of defending white's weak queenside
pawns, but it doesn't mean that it is
happy in its work! 28.£xg7+ ¢xg7

Black should be happy, his dark square
bishop is nicely cooperating with the
pawn structure. But the relief has come
at a cost, e6 pawn is weak and white is

clear example of a strategy, that is very
efficient: consequent play at limiting
opponents possibilities.
It is much more difficult than trying to
"come first" (towards king or with pawn

have mastered the art of "limiting" play in
many brilliant games. ¥b6

square strictly is not an outpost, as it

Knight being placed there takes a

getting into the d-file. White is winning
here, even being a pawn down. 27.¦ac1

Wells: 'This position is in fact considered
in my book piece power. There I pointed
out that white's recapture with the bishop
was incorrect, because it enabled black
to implement his plan of isolating and

then blockading the white d-pawn with a
really text-book clarity. This example
merits another look.' 13.£xf3

[ 13.¥xf3?! Wells c6 14.a4 cxd5
15.exd5 ¤c4 16.b3 ¤d6 The classic

blockader! As the textbooks are keen
to tell you the knight is happy here
because he can best combine this
defensive function with a continued
offensive influence on the position. Its
all true! Here black also has chances
of a dark-square bind ( we shall see
several cases later of where giving up
a bishop on one coloured square
promotes the chances of creating play
on the others .) Its implimentation turns
out to be almost eerily smooth. Black is
even able to exchange dark-squared
bishops and end up with the 'dream'
good knight v. genuinely fumbling
bishop ending. 17.¥a3 ¤ef5 18.¤e4

black has to be precise in order to solve
mounting problems. Wells: 'This I like
though it looks as if black, frustrated by
his inability to blockade on d6 would land
a compensatory square on d4. However,

white prepares that knights immediate
exchange, and althougj there will be a
'contest' of passed d-pawns, white's
bishop pair will come into its own again.'
