THE RIGHT
EXCHANGE
IOI
2 .•• ~xe3!
Of course' Black wins a rook and two pawns
for bishop and knight, which is more than sufficient.
3 fxe3 ~xe3+ 4 @f3 ~xfl 5 ~xfl !txcl
Here Black forces this exchange mainly to
seize the c-file. However, it is generally accepted
that, with the present distribution of material,
the exchange of a pair of rooks generally
favours the side with the two rooks.
6 ~xcl ~c8!
The black rook becomes active, taking advantage
of the fact that the white pieces are momentarily
uncoordinated and also eyeing the
important a3-pawn.
7 ~b2~c2!
After 7 ... e5? 8 ~e3! White overprotects the
invasion point c2, after which he can still offer
strong resistance.
8 ~xf6 :Sa2 9 'ite3 ~a3
The rook has cleared the way for his a- and
b-pawns. Now Black should win.
10 ~d2 b5 ll toe4 b4? (D)
Carelessly played; Black complicates his
task. Now the white king gains access to the
c4-square and holds up the black passed pawns
for the time being. 11.. .a5 was more precise.
18 ~e7 e5
To break down White's defences, Black must
bring his king into the game.
19 g4 ~cl+ 20@b3@d5 21..tgS ~bl+ 22
@c2~hl
Again threatening ... a4.
23 @b3 ~3! 24 ~f6+
24@c2a4-+.
24 ... @d4 25 ~xh7 ~xd3+ 26 @c2 a4
Now the advance of the black passed pawns
can no longer be prevented.
