Black has a slight material plus - the exchange
for a pawn. But his king position is insecure.
If you add to this Black's weakened dark
squares when his opponent has a dark-squared
bishop, then White's position looks the more
promising.

Well then ... The dark-squared bishop and the
queen are already attacking White's king position.
Black's light-squared bishop has acquired
freedom. The passed pawn on c4 will be supported
from the rear by the major pieces. And
all this has merely cost the exchange. But here
again, let us try to state some useful generalizations.
In open positions where the knight has no
outposts in the centre, the strength of two bishops
and a pawn is no less (and tends to be
greater) than that of a rook and knight.
From this it is clear that the diagram position
must be recognized as favouring Black.
