and thus the character of the position substantially
alters, it is essential to assess the newlyarisen
position correctly and precisely. It often
happens that pieces which had little or no
scope before the exchanging combination are
suddenly able to develop previously unforeseen
activity after the exchange of the other
pieces. In the following game Polugaevsky
played a combination which won two pawns
and even activated his rook, and yet he still
Jost.

Unfortunately for Black, it turns out that he
now has no good way of parrying the threat of 7
!k8 followed by .!oe7+.
Black enjoys an extra pawn. However, in return
White has the bishop-pair and his queen is
very active. A further important criterion for assessing
this position is the contrasting situation
of the kings. Whereas with queens on the board
the white king is always going to be a bit insecure,
after the exchange of queens, the king can
venture forward and actively join the fight. But
with his next move Black discounts this factor.

Black answers the question of the right exchange
incorrectly. He wants to exchange the
active white queen but the exchange of queens
only plays into White's hands. Correct was
1...'&d7 2 ~e3 ~d8, since after 3 \l!Ub6? the
black queen will become active: 3 ... ~f6+ 4

Once more Black fails to solve the problem
of the right exchange. It was time to look for a
way of drawing the game. 3 ... .i.b51 would not
only have split up the white bishop-pair, but it
would also have prepared the exchange of the
a2-pawn; for example, 4 ~xb5 loxb5 5 ~c5 (5
