THE RIGHT
EXCHANGE
77
be a particularly faulty exchange here, since the
e4-pawn would considerably hamper the hannonious
development of the white pieces.
5ii..h4!
White preserves his bishop from possible exchange.
After 5 cxd5?! lcixg5 6 h4 lcie4 7 lcixe4
'&xd5 8 lcic3 '&a5 the exchanges would bring
about the first material imbalance; Black would
have the bishop-pair. Theory evaluates the resulting
position as favourable to Black.

Question: should Black play 8 ... cxd4?
8 ••• cxd4?!
Black answers the exchanging question incorrectly.
He seeks simplification, but this does
not always bring any real relief. 8 ... loc6!? or
8 ... ii..g7!? should be preferred.

White transfers the knight to the queenside,
to provoke weaknesses there.

This time it is White who makes the wrong
exchanging decision. It is understandable that
he wants to invade the seventh rank as quickly
as possible, but in doing so he allows the exchange
of his important light-squared bishop.
He should have played 20 ii..f3! ± first.
What should Black play here?
25 ii..gl?
25 lcib4! is the best move - pawn exchange
as a defensive strategy! If Black manages to exchange
the a2-pawn his drawing chances will
increase quite considerably; for example, 26
